Description

KEYBOARD- VIDEO-MOUSE SYSTEM AND METHOD OF PROVIDING AND

USING THE SAME

FIELD OF THE INVENTION

[0001] This invention relates generally to keyboard- video-mouse systems, and relates more particularly to such systems having virtual ports to configure user interfaces of the systems and methods of providing and using the same.

CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. Provisional Application No. 61/482,850, filed May 5, 2011. U.S. Provisional Application No. 61/482,850 is incorporated herein by reference in its entirety.

DESCRIPTION OF THE BACKGROUND

[0003] Keyboard-video-mouse systems (i.e., systems employing a keyboard-video-mouse (KVM) switching device) represent a class of switching systems designed to provide user(s) centralized control and monitoring of one or more host computers from a control terminal (e.g., keyboard, monitor and mouse). The control terminal is frequently located remotely from the host computers. Through the KVM switching device, the user(s) can select and switch between the one or more host computers to operate the one or more host computers with the control terminal. The KVM switching device routes audio-visual data of the selected host computer to the control terminal so that the user(s) may view and/or listen to the audio-visual data at the control terminal. The KVM switching device also routes the signals from peripheral input devices of the control terminal (e.g., a keyboard and/or a mouse of the control terminal) to the respective peripheral input device ports of the selected host computer. From the host computer's perspective, it appears as if the control terminal's peripheral input devices are directly coupled to the host computer. The user(s) may select which host computer to operate from the control terminal with a user interface of the KVM system that is configured to control the KVM switching device.

[0004] Accordingly, a need or potential for benefit exists for an apparatus or system that can permit a user to pair a user interface with a KVM switching device and/or to configure the user interface to permit the user interface to control the KVM switching device.

DETAILED DESCRIPTION OF EXAMPLES OF EMBODIMENTS

[0043] Some embodiment include a system. The system comprises a keyboard- video-mouse switching device. The keyboard-video-mouse switching device is configured to communicate with one or more host computer systems, a control terminal, and a user interface. The keyboard- video-mouse switching device can comprise a virtual port through which the user interface communicates with the keyboard-video-mouse switching device and one or more physical ports through which the one or more host computer systems communicate with the keyboard-video- mouse switching device. Further, the user interface can be configured to permit selection of at least one selected host computer system of the one or more host computer systems after the user interface is paired with the keyboard- video-mouse switching device. However, the user interface can be unable to select the at least one selected host computer system of the one or more host computer systems until the user interface is paired with the keyboard-video-mouse switching device. Meanwhile, when the keyboard-video-mouse switching device is communicating with the one or more host computer systems and the control terminal and when the user interface is paired with the keyboard-video-mouse switching device, the keyboard- video-mouse switching device is configured to route host computer audio-visual data from the at least one selected host computer system of the one or more host computer systems to the control terminal.

The method can comprise: manufacturing a keyboard-video-mouse switching device comprising a virtual port and one or more physical ports; configuring the keyboard-video-mouse switching device to communicate with one or more host computer systems, a control terminal, and a user interface, the keyboard-video-mouse switching device being configured to communicate with the user interface through the virtual port and to communicate with the one or more host computer systems through the one or more physical ports; configuring the user interface to permit selection of at least one selected host computer system of the one or more host computer systems after the user interface is paired with the keyboard-video-mouse switching device; configuring the user interface to be unable to select the at least one selected host computer system of the one or more host computer systems until the user interface is paired with the keyboard-video-mouse switching device; and configuring the keyboard-video-mouse switching device such that when (a) the keyboard-video-mouse switching device is communicating with the one or more host computer systems and the control terminal and (b) the user interface is paired with the keyboard-video-mouse switching device, the keyboard-video-mouse switching device is configured to route host computer audio-visual data from the at least one selected host computer system of the one or more host computer systems to the control terminal.

[0045] Further embodiments include a method. The method can comprise: detecting a user interface at a virtual port of a keyboard-video-mouse switching device when the user interface is coupled with the keyboard-video-mouse switching device, the keyboard-video-mouse switching device being configured to communicate with one or more host computer systems, a control terminal, and the user interface; pairing the user interface to the keyboard-video-mouse switching device; and receiving a selection of at least one selected host computer system of the one or more host computer systems at the keyboard-video-mouse switching device via one or more user interface inputs of the user interface when the user interface is paired with the keyboard-video-mouse switching device.

[0046] Turning to the drawings, FIG. 1 illustrates system 100, according to one embodiment. System 100 is merely exemplary and is not limited to the embodiments presented herein. System 100 can be employed in many different embodiments or examples not specifically depicted or described herein.

[0047] System 100 comprises keyboard- video-mouse (KVM) switching device 101. KVM switching device 101 is configured to route host computer audio-visual data (e.g., audio data and/or video data) from one or more host computer systems 102 to control terminal 113. For example, KVM switching device 101 can be configured to route the host computer audio-visual data from one or more presently selected host computer systems (e.g., host computer system 103) of host computer system(s) 102 to control terminal 113. Generally speaking, the presently selected host computer system(s) only comprises one host computer system of host computer system(s) 102 although the presently selected host computer system(s) could comprise multiple ones of host computer system(s) 102 in some embodiments. Accordingly, one or more users of system 100 and/or KVM switching device 101 can select from which of host computer system(s) 102 (e.g., host computer system 103) to receive the host computer audio-visual data at control terminal 113 by using user interface 111, as described in further detail below. As a result, KVM switching device 101 is configured to provide control (e.g., centralized control) of host computer system(s) 102 (e.g., to the user(s) of system 100 and/or KVM switching device 101) via user interface 111. FIG. 15 illustrates an exemplary system 100 being used by the user(s).

[0048] Control terminal 113 can comprise audio-visual display device 114 (e.g., an electronic visual display such as a computer monitor and/or the like), one or more peripheral input devices 117 (e.g., computer keyboard 115, computer mouse 116, and/or the like), and/or at least one speaker (not shown). Audio-visual device 114 can be similar or identical to refreshing monitor 1706 (FIGs. 17 & 18). Computer keyboard 115 can be similar or identical to keyboard 1704 (FIGs. 17 & 18). Computer mouse 116 can be similar or identical to mouse 1710 (FIGs. 17 & 18). The speaker(s) can be integrated with and/or separate from audio-visual display device 114. Audio-visual display device 114 and/or the speaker(s) can be configured to present the host computer audio-visual data to the user(s) of control terminal 113. Peripheral input device(s) 117 can be configured to permit the user(s) to provide command data (e.g., one or more user input(s)) to host computer system(s) 102 and/or KVM switching device 101 in order to communicate with and/or to operate host computer system(s) 102 and/or KVM switching device 101. Accordingly, when the user(s) are operating peripheral input device(s) 117 of control terminal 113, KVM switching device 100 can also be configured to route the command data from peripheral input device(s) 117 of control terminal 113 to host computer system(s) 102. In some embodiments, system 100 can comprise one or more of control terminal 113, one or more of audio-visual display device 114, and one or more of peripheral input device(s) 117 such as keyboard 115, mouse 116, and/or the speaker(s). The interactions of control terminal 113, audio-visual display device 114, peripheral input device(s) 117, keyboard 115, mouse 116, and/or the speaker(s), with respect to routing the audio-visual data and/or the command data, are described in further detail below with respect to FIG. 2.

[0049] In many embodiments, host computer system(s) 102 can comprise four computer system (e.g., host computer system 103, host computer system 104, host computer system 105, and/or host computer system 106). In other embodiments, host computer system(s) 102 can comprise more or less than four computer systems. Each host computer system of host computer system(s) 102 (e.g., host computer system 103, host computer system 104, host computer system 105, and/or host computer system 106) can be similar or identical to computer system 1700 (FIG. 17), as described below. In another embodiment, each host computer system of host computer system(s) 102 (e.g., host computer system 103, host computer system 104, host computer system 105, and/or host computer system 106) can be similar or identical to chassis 1702 (FIG. 17) of computer system 1700 (FIG. 17) and the circuit board(s) and/or other component(s) contained in chassis 1702 (FIG. 17), as described below. In some embodiments, system 100 can comprise two or more of host computer system(s) 102 (e.g., host computer system 103, host computer system 104, host computer system 105, and/or host computer system 106). In various embodiments, any host computer system of host computer system(s) 102 can be configured to require a common access card (CAC) (e.g., authentication and/or validation of the CAC) in order to be secured and/or operated, as described in further detail below.

[0050] System 100 and/or KVM switching device 101 can comprise one or more switching device peripheral device(s) 120 configured to communicate with KVM switching device 101. In many embodiments, switching device peripheral device(s) 120 can comprise CAC reader 121. CAC reader 121 can be configured to receive the CAC and permit the user(s) to access one or more of host computer system(s) 102 when any of those host computer systems require CAC access. In the same or different embodiments, switching device peripheral device(s) 120 can comprise any suitable other slave device 122 (e.g., a printer, an external hard drive, a modem, one or more speakers, etc.). In some embodiments, any of switching device peripheral device(s) 120 can be part of and/or can be located at control terminal 113 (e.g., for ease of access to the user(s) of system 100). In other embodiments, one or more of switching device peripheral device(s) 120 can be located remotely from terminal 113. KVM switching device 101 can permit communication between the switching device peripheral device(s) 120 and the appropriate host computer system(s) 102. In many embodiments, switching device peripheral device(s) 120 can be coupled to KVM switching device 101 via different connectors (although the connectors may be the same type of connectors) than peripheral input device(s) 117.

[0051] Further, system 100 can comprise user interface 111. As mentioned briefly above, user interface 111 can be configured to control KVM switching device 101, thereby facilitating control (e.g., central control) of host computer system(s) 102. Accordingly, KVM switching device 101 can be configured to communicate with user interface 11 1. In many embodiments, user interface 111 can be coupled (e.g., mechanically and/or electrically) with KVM switching device 101. Coupling user interface 111 to KVM switching device 101 can facilitate communication between user interface 111 and KVM switching device 101 and also can facilitate communication between KVM switching device 101 and host computer system(s) 102.

[0052] User interface 111 can be integrated with or separate from KVM switching device 101. Further, user interface 111 can be configured to communicate with KVM switching device 101 through wired and/or wireless communication. For example, user interface 111 can be configured to communicate with KMC switching device 101 via (a) one or more components configured to provide wired communication (e.g., one or more data buses, such as, for example, universal serial bus(es); one or more networking cables, such as, for example, coaxial cable(s), optical fiber cable(s), twisted pair cable(s); any other suitable data cable, etc.) and/or (b) one or more components configured to provide wireless communication (e.g., one or more radio transceivers, one or more infrared transceivers, etc.). Further, the wired and/or wireless communication can be implemented using any one or any combination of wired and/or wireless communication network topologies (e.g., ring, line, tree, bus, mesh, star, daisy chain, hybrid, etc.) and/or protocols (e.g., personal area network (PAN) protocol(s), local area network (LAN) protocol(s), wide area network (WAN) protocol(s), cellular network protocol(s), Powerline network protocol(s), etc.). Exemplary PAN protocol(s) can comprise Bluetooth, Zigbee, Wireless Universal Serial Bus (USB), Z-Wave, etc.; exemplary LAN and/or WAN protocol(s) can comprise Institute of Electrical and Electronic Engineers (IEEE) 802.3, IEEE 802.11, etc.; and exemplary wireless cellular network protocol(s) can comprise Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Evolution-Data Optimized (EV-DO), Enhanced Data Rates for GSM Evolution (EDGE), 3GSM, Digital Enhanced Cordless Telecommunications (DECT), Digital AMPS (IS-136/Time Division Multiple Access (TDMA)), Integrated Digital Enhanced Network (iDEN), etc. The components implementing the wired and/or wireless communication can be dependent on the network topologies and/or protocols in use, and vice versa.

[0053] Accordingly, in many embodiments, when user interface 111 is separate from KVM switching device 101, user interface 111 can operate as a remote user interface. For example, user interface 111 could communicate with KVM switching device 101 using a mesh wireless communication network such as a Bluetooth™ mesh computer network connection. However, in many examples, using wired communication between user interface 111 and KVM switching device 101 can provide increased security of the host computer audio-visual data where heightened security is an issue. When user interface 111 is configured to communicate with KVM switching device 101 through a wired coupling, user interface 111 can comprise the cable and/or bus connector (e.g., the cable and/or bus connector can be integral with user interface 111). The cable and/or bus connector can be approximately 3.05 meters (10 feet) in length. In some embodiments, the cable and/or bus connector can be coupled to KVM switching device 101 via a latching connector. In many embodiments, user interface 111 is not an onscreen display (OSD) (i.e., user interface 111 is not provided (e.g., displayed) via control terminal 113 and/or audio-visual display device 114), but rather is a separate electronic device.

[0054] Operating user interface 111 remotely from KVM switching device 101 can provide various advantages to the user(s) employing system 100. For example, the user(s) of system 100 can operate user interface 111 at a location proximate to control terminal 113 (e.g., on a desktop surface supporting control terminal 113) while the remaining elements of system 100 (e.g., KVM switching device 101, host computer system(s) 102, etc.) can be located elsewhere (e.g., under the desk having the desktop surface and/or in another room, building, etc.), thereby reducing the spatial volume of system 100 located proximate to control terminal 113 (e.g., saving space on the desktop surface) and/or the user(s). In the same example, user interface 111 could be located near peripheral input device(s) 117 (e.g., mouse 116) of control terminal 113. Meanwhile, operating user interface 111 also can provide ease of switching between host computer system(s) 102 by bringing user interface 111 to the user(s) as opposed to requiring the user(s) to go to KVM switching device 101, which may be inconveniently located away from control terminal 113 and/or the user(s) (e.g., under the desktop surface supporting control terminal 113 mentioned above), thereby minimizing switching errors (e.g., by switching to an incorrect host computer system) and/or providing clear, unambiguous indication of which host computer system is presently selected, as explained in greater detail below. [0055] Operating user interface 111 remotely from KVM switching device 101 can also provide various advantages to technicians tasked with installing and maintaining system 100. For example, operating user interface 1 11 remotely from KVM switching device 101 can permit quicker deployment and/or easier replacement of system 100, KVM switching device 101, and/or user interface 111. Likewise, operating user interface 111 remotely from KVM switching device 101 can further improve reliability and durability of system 100, KVM switching device 101, and/or user interface 111, reducing the need for technical support of system 100, KVM switching device 101, and/or user interface 111.

[0056] User interface 111 can comprise one or more user interface inputs (e.g., capacitive buttons, resistive buttons, and/or mechanical buttons) permitting the user(s) of system 100 to select from which host computer system(s) of host computer system(s) 102 to route the host computer audio-visual data to control terminal 113, where each user interface input is associated with one physical port of KVM switching device 101, as described in further detail below. Meanwhile, user interface 111 can be configured (e.g., by the user(s), as described below) to associate a number, name, symbol, and/or a color with each respective host computer system of host computer system(s) 102 by assigning that number, name, symbol, and/or color that is associated with the respective host computer system of host computer system(s) 102 to the user interface input associated with that physical port to which the respective host computer system is coupled. The user(s) of system 100 can customize the association of a number, name, symbol, and/or color established by user interface 111 during configuration of user interface 111, as described below. In some embodiments, the number associated with each user interface input is static and not subject to customization but the name, symbol, and/or color remain subject to customization. In various embodiments, the user interface input(s) can be recessed into the front surface of user interface 111 to prevent accidental activation by the user(s) of system 100.

[0057] In some embodiments, user interface 111 can comprise an electronic display (e.g., a liquid crystal display such as a monochrome liquid crystal display, an organic light emitting diode display, etc.). The electronic display can comprise a touch screen electronic display (e.g., a capacitive or a resistive touch screen electronic display). The electronic display can comprise the user interface input(s), and/or the user interface input(s) can be separate from the electronic display, as shown in FIG. 1. In the same or different embodiments, the user interface input(s) can comprise one or more light emitting diodes (e.g., red-green-blue (RGB) light emitting diodes) configured to emit one or more colors (e.g., whichever color is selected for association with that particular user interface input and/or that host computer system coupled to the physical port with which that particular user interface input is associated). In other embodiments, when the user interface input(s) are implemented as mechanical buttons as opposed to capacitive and/or resistive buttons operating as part of an electronic display of user interface 111, the user interface input(s) can comprise the light emitting diodes (i.e., because the color coding could otherwise be implemented at the electronic display as opposed to the separate light emitting diodes).

[0058] For example, user interface 111 can comprise an organic light emitting diode (OLED) capacitive electronic display (e.g., an OLED touch screen display). In some embodiments, the user interface input(s) can comprise capacitive buttons displayed on the OLED capacitive display. Each user interface input can display the name, symbol, and/or color associated with the respective host computer system coupled to the physical port with which that user interface input is associated.

[0059] In another example, user interface 111 can comprise a monochrome liquid crystal display and the user interface input(s) can comprise one or more mechanical buttons positioned adjacent to the liquid crystal display. Accordingly, each user interface input can comprise one or more light emitting diodes configured to emit one or more colors, as determined upon configuration of user interface 111 by the user(s). A number can be pre-assigned to each user interface input, and the liquid crystal display can be configured to display a name associated with each of the user interface input(s) (e.g., at least for those user interface input(s) that are coupled to a host computer system of host computer system(s) 102) next to that respective user interface input of the user interface input(s).

[0060] Turning ahead in the drawings, FIG. 23 illustrates an exploded view of an exemplary user input 2300 implemented as a mechanical button, according to an embodiment. User input 2300 can be similar or identical to one of the user input(s) described above with respect to system 100 (FIG. 1). Accordingly, multiple of user input 2300, as described below, can be implemented to provide the user input(s) of system 100 (FIG. 1).

[0061] User input 2300 can comprise face portion 2301 and connector portion 2302. Face portion 2301 can comprise opening 2304 and can be configured to couple with connector portion 2302. When face portion 2301 is coupled with connector portion 2302, user input 2300 can comprise recess 2305. In some embodiments, face portion 2301 can also comprise opening

2306. Further, user input 2300 can comprise color chip 2303. Meanwhile, connector portion 2302 can comprise coupling mechanism 2307.

[0062] Connector portion 2302 can be coupled to a user interface via coupling mechanism

2307. For example, the user interface can be similar or identical to user interface 111. Accordingly, user input 2300 can be coupled to the user interface via connector portion 2302. An electronic display of the user interface can be positioned proximate to user input 2300 so as to display a relevant number, name, symbol, and/or color associated with user input 2300 next to user input 2300. The electronic display can be similar or identical to the electronic display of user interface 111.

[0063] Color chip 2303 can be coupled with user input 2300, thereby permitting association of a color of color chip 2303 with user input 2300, such as, for example, to permit distinction of user input 2300 from another user input. Further, color chip 2303 can be interchangeable with one or more other color chips similar or identical to color chip 2303 so that user input 2300 can be customized by the user(s) of user input 2300. For example, color chip 2303 and the other color chips each can comprise different colors configured to permit differentiation of each of color chip 2303 and the other color chips from each other. User input 2300 and/or recess 2305 can be configured to receive color chip 2303, and recess 2305 can be shaped to match a shape of color chip 2303. For example, color chip 2303 and recess 2305 can be approximately semicircular in shape although other suitable shapes can also be used. Accordingly, recess 2305 can be configured to receive color chip 2303 via opening 2304. That is, color chip 2303 can be inserted into recess 2303 through opening 2304 and where applicable, around to opening 2306 on an opposite side of recess 2305 from opening 2304. Color chip 2303 can be removable from user input 2300 and/or recess 2305, such as, for example, when face portion 2301 comprises opening 2306. For example, by application of force (e.g., via a pin or a similarly pointed object, such as, for example, an unfolded paper clip) to color chip 2303 through opening 2306, color chip 2303 can be partially pressed out of recess 2305 via opening 2304 and extracted from recess 2305 via opening 2304. Accordingly, color chip 2303 can be replaced with another color chip, as desired. In some embodiments, one or more of the color chips (e.g., color chip 2303) can comprise the same color, as desirable. Color chip 2303 can comprise a marker (e.g., an arrow) to indicate how to insert color chip 2303 into opening 2304 and/or recess 2305.

[0064] FIGs. 24-28 illustrate user input 2300 from various different views when user input has received color chip 2303, according to the embodiment of FIG. 23. For example, FIG. 24 shows a front, right, top isometric view of user input 2300. FIG. 25, shows a rear, right, top isometric view of user input 2300. FIG. 26, shows a front, bottom isometric view of user input 2300. FIG. 27 shows a front, top isometric view of user input 2300. Finally, FIG. 28, shows a front view of user input 2300.

[0065] Returning now to FIG. 1, by implementing the user interface input(s) as part of an electronic display of user interface 111, user interface 111 can be smaller and therefore occupy less space. This approach can also remove redundancy where a number, name, symbol, and/or color of the port might otherwise be displayed both on the electronic display and separate user interface input(s). Likewise, this approach can offer a singular point of feedback as well as higher visibility than alternative approaches for implementing the user interface input(s) as a result of higher contrast and/or resolution provided by the electronic display.

[0066] In an operational example of user interface 111, illumination and/or color of the number associated with each of the user interface input(s) can indicate whether or not there is a host computer system of host computer system(s) 102 coupled to the physical port with which that user interface input is associated (i.e., whether or not the user interface input and/or the related physical port are presently active) and/or whether or not the host computer coupled to the physical port with which each of the respective user interface input(s) is associated is presently selected for use by the user(s). For example, the number of any user interface input that is presently active, but not presently selected, can be illuminated and/or colored to appear light grey whereas the number of inactive user inputs can appear dark grey. Meanwhile, the number of any presently selected and active user interface input (i.e., host computer system) can be illuminated and/or colored white. Further, the user interface input(s) can indicate whether or not CAC access is required to login to the host computer system related to that particular user interface input, such as, for example, by displaying a symbol (e.g., an icon of a card) at each of the user interface input(s) indicative of whether or not CAC access is required to login to the host computer system related to that particular user interface input.

[0067] User interface 111 can comprise a housing (e.g., a plastic housing). For increased security, the housing can be sealed with tamper-evident labels to indicate if the housing has been compromised. FIG. 14 illustrates an exemplary user interface 111 (FIG. 1) and/or exemplary user interface input(s) of user interface 111 (FIG. 1).

[0068] Meanwhile, user interface 111 can also be configured to be paired with (e.g., authenticated by) KVM switching device 101. In various embodiments, only one user interface 111 can be paired with KVM switching device 101 at any given time. In many embodiments, user interface 111 can be configured not to communicate with KVM switching device 101, or vice versa, until user interface 111 is paired with KVM switching device 101. In the same or different embodiments, KVM switching device 101 can be configured such that user interface 111 cannot communicate with and/or control KVM switching device 101 until the user interface 111 has been configured by the user(s). FIG. 2 is a block diagram illustrating system 100, according to the embodiment of FIG. 1. FIG. 2 helps to illustrate system 100, KVM switching device 101, and/or user interface 111 in operation generally and also helps to illustrate pairing user interface 111 with KVM switching device 101 as well as configuring user interface 111 to permit user interface 111 to control KVM switching device 101.

[0069] Referring now to FIG. 2, KVM switching device 101 (FIG. 1) comprises KVM circuitry 201. KVM circuitry 201 can be configured to permit KVM switching device 101 (FIG. 1) to route the host computer audio-visual data from host computer system(s) 102 (FIG. 1) to control terminal 113 (FIG. 1). KVM circuitry 201 can comprise one or more physical port(s) 207 (e.g., physical port 202, physical port 203, physical port 204, and/or physical port 205). Each physical port of physical port(s) 207 can be configured to couple with one host computer system of host computer system(s) 102 (FIG. 1). Each physical port of physical port(s) 207 can comprise at least one audio-visual input connector and at least one peripheral input device connector. For example, the audio-visual input connector(s) can comprise any suitable audiovisual device connector(s) (e.g., a universal serial bus (USB) connector, a high-definition multimedia interface (HDMI) connector, a digital visual interface (DVI) connector, a display port (DP) connector, a video graphics array (VGA) connector, composite cable connectors, an S- Video connector, an optical audio connector, Radio Corporation of America (RCA) connectors, a tip-ring-sleeve (TRS) connector such as a 3.5 millimeter TRS connector, etc.) and can be configured to receive a corresponding data cable and/or bus configured to couple to any appropriate corresponding audio-visual input connector(s) of the corresponding host computer system of host computer system(s) 102 (FIG. 1). Further, the peripheral input device connector(s) can comprise any suitable peripheral input device connectors (e.g., a USB connector, a keyboard/mouse connector, etc.) and can be configured to receive a corresponding data cable and/or bus configured to couple to any appropriate corresponding peripheral input device connector(s) of the corresponding host computer system of host computer system(s) 102 (FIG. 1). Meanwhile, KVM circuitry 201 can also comprise separate audio-visual input connector(s) and peripheral input device connector(s) configured to couple control terminal 113 (FIG. 1) (e.g., audio-visual display device 114 (FIG. 1), the speaker(s) of control terminal 113 (FIG. 1), peripheral input device(s) 117 (FIG. 1), computer keyboard 115 (FIG. 1), computer mouse 116 (FIG. 1), etc.) to KVM switching device 101 (FIG. 1). Accordingly, KVM circuitry 201 can comprise any suitable electrical networks configured to route host computer audiovisual data from any appropriate host computer system(s) (e.g., the presently selected host computer system(s)) of host computer system(s) 102 (FIG. 1)) through the corresponding physical port of physical port(s) 107 (FIG. 1) to control terminal 113 (FIG. 1) via the corresponding data cable(s) and/or bus(es) and data cable and/or bus connector(s), as appropriate. Likewise, KVM circuitry 102 (FIG. 1) can comprise any suitable electrical networks configured to route command data from control terminal 113 (FIG. 1) to the appropriate host computer system(s) (e.g., the presently selected host computer system(s)) of host computer system(s) 102 (FIG. 1)) and/or virtual port 206, as described below, via the corresponding data cable(s) and/or bus(es) and data cable and/or bus connector(s), as appropriate. Further, KVM circuitry 201 and/or its electrical networks can comprise any suitable electrical switches for implementing the KVM functionality of KVM switching device 101 (FIG. 1), as is well known to those having ordinary skill in the art such that it will not receive a detailed description herein. Further still, KVM circuitry 201 can comprise any suitable electrical networks configured to permit host computer(s) 102 (FIG. 1) and/or control terminal 113 (FIG. 1) to communicate with switching device peripheral device(s) 120 (FIG. 1), as applicable. Although communication between host computer system(s) 102 (FIG. 1), switching device peripheral device(s) 120 (FIG. 1), control terminal 113 (FIG. 1), and KVM switching device 101 (FIG. 1), is generally described here with respect to wired communication, wireless communication similar to that described above with respect to the communication between KVM switching device 101 (FIG. 1) and user interface 111 (FIG. 1) could alternatively and/or additionally be implemented here.

[0070] KVM switching device 101 (FIG. 1) also can comprise virtual port 206. In some embodiments, virtual port 206, KVM system 100 (FIG. 1), and/or KVM switching device 101 (FIG. 1) can comprise a virtual port computer system. In the same or different embodiments, virtual port 206 can be configured to communicate with the virtual port computer system. The virtual port computer system can be similar or identical to computer system 1700 (FIG. 17), as described below. In another embodiment, the virtual port computer system can be similar or identical to chassis 1702 (FIG. 17) of computer system 1700 (FIG. 17) and the circuit board(s) and/or other component(s) contained in chassis 1702 (FIG. 17), as described below. In many respects, virtual port 206 can be similar to any physical port of physical port(s) 107 but for that virtual port 206 and/or the virtual port computer system can be part of (e.g., internal to and/or integral with) KVM switching device 101 (FIG. 1).

[0071] In many embodiments, one or more of the audio-visual input connector(s) and/or peripheral input device connector(s) of virtual port 206 and/or one or more of physical port(s) 207 can be implemented as electrical networks of KVM circuitry 201 (i.e., the audio-visual input connector(s) and/or peripheral input device connector(s) would not be externally accessible to the user(s)). Still, in many embodiments, virtual port 206 comprises another physical port similar or identical to physical port(s) 107 (FIG. 1) and can be physically located at the exterior of KVM switching device 101 (FIG. 1) (i.e., making virtual port 206 externally accessible to the user(s)). Regardless of the manner of implementation, virtual port 206 and/or the virtual port computer system (a) can be configured to route switching device audio-visual data from virtual port 206 and/or the visual port computer system to control terminal 113 and/or (b) can be configured to receive command data from control terminal 113 (FIG. 1) (e.g., from peripheral input device(s) 117 (FIG. 1)) through any of the various data cable(s) and/or bus(es) and data cable and/or bus connector(s) coupling KVM switching device 101 (FIG. 1) and control terminal 113 (FIG. 1), as appropriate. Still, in many embodiments, the virtual port computer system may not have the level of sophistication and/or complexity of host computer system(s) 102 (FIG. 1). For example, the virtual port computer system may only have those processing capabilities and/or memory storage capabilities as are reasonably necessary to pair user interface 111 (FIG. 1) with KVM switching device 101 (FIG. 1) and/or to configure KVM switching device 101 (FIG. 1), as is described in further detail below. In these examples, the virtual port computer system could simply be implemented as a microcontroller comprising flash memory, or the like. Reducing the sophistication and/or complexity of the virtual computer system can reduce the size and/or cost of implementing system 100 (FIG. 1). Nonetheless, in other embodiments, the virtual port computer system may need additional sophistication and/or complexity to operate as desired.

[0072] Virtual port 206, KVM switching device 101 (FIG . 1), and/or the virtual computer system can comprise one or more memory storage modules (e.g., the storage modules of computer system 1700 (FIG. 17) and/or flash memory, as described above). The memory storage module(s) can be configured to store a code indicating the pairing of user interface 111 (FIG. 1) with KVM switching device 101 (FIG. 1), an indicator (e.g. a flag) of whether user interface 111 (FIG. 1) is presently configured, and/or configuration settings (e.g., numbers, names, symbols, and/or colors associated with the user interface input(s), the physical port(s) of the user interface, and/or the host computer system(s) as described above with respect to system 100 (FIG. 1)).

[0073] Skipping ahead now in the drawings, FIG. 17 illustrates an exemplary embodiment of computer system 1700 and chassis 1702 (and its internal components) that can be suitable for implementing an embodiment of host computer system(s) 102 (FIGs. 1 & 2), the virtual port computer system, and/or a user interface computer system and/or another part of system 100 (FIGs. 1 & 2) as well as methods 1600 (FIG. 16) and 3100 (FIG. 31) and/or any of the various procedures, processes, and/or activities of methods 1600 (FIG. 16) and/or 3100 (FIG. 31). One or more parts of computer system 1700 (e.g., refreshing monitor 1706, keyboard 1704, and/or mouse 1710, etc.) may also be appropriate for implementing control terminal 113 (FIG. 1). Computer system 1700 includes chassis 1702 containing one or more circuit boards (not shown), Universal Serial Bus (USB) 1712, Compact Disc Read-Only Memory (CD-ROM) and/or Digital Video Disc (DVD) drive 1716, and hard drive 1714. A representative block diagram of the elements included on the circuit boards inside chassis 1702 is shown in FIG. 17. Central processing unit (CPU) 1810 in FIG. 18 is coupled to system bus 1814 in FIG. 18. In various embodiments, the architecture of CPU 1810 can be compliant with any of a variety of commercially distributed architecture families.

[0074] System bus 1814 also is coupled to memory 1808, where memory 1808 includes both read only memory (ROM) and random access memory (RAM). Non- volatile portions of memory 1808 or the ROM can be encoded with a boot code sequence suitable for restoring computer system 1700 (FIG. 17) to a functional state after a system reset. In addition, memory 1808 can include microcode such as a Basic Input-Output System (BIOS). In some examples, the one or more storage modules of the various embodiments disclosed herein can include memory 1808, USB 1712 (FIGs. 17-18), hard drive 1714 (FIGs. 17-18), and/or CD-ROM or DVD drive 1716 (FIGs. 17-18). In the same or different examples, the one or more storage modules of the various embodiments disclosed herein can comprise an operating system, which can be a software program that manages the hardware and software resources of a computer and/or a computer network. The operating system can perform basic tasks such as, for example, controlling and allocating memory, prioritizing the processing of instructions, controlling input and output devices, facilitating networking, and managing files. Examples of common operating systems can include Microsoft® Windows, Mac® operating system (OS), UNIX® OS, and Linux® OS. Common operating systems for a mobile electronic device include the iPhone® operating system by Apple Inc. of Cupertino, CA, the Blackberry® operating system by Research In Motion (RIM) of Waterloo, Ontario, Canada, the Palm® operating system by Palm, Inc. of Sunnyvale, CA, the Android operating system developed by the Open Handset Alliance, the Windows Mobile operating system by Microsoft Corp. of Redmond, WA, or the Symbian operating system by Nokia Corp. of Espoo, Finland.

[0075] As used herein, "processor" and/or "processing module" means any type of computational circuit, such as but not limited to a microprocessor, a microcontroller, a controller, a complex instruction set computing (CISC) microprocessor, a reduced instruction set computing (RISC) microprocessor, a very long instruction word (VLIW) microprocessor, a graphics processor, a digital signal processor, or any other type of processor or processing circuit capable of performing the desired functions. [0076] In the depicted embodiment of FIG. 18, various I/O devices such as disk controller 1804, graphics adapter 1824, video controller 1802, keyboard adapter 1826, mouse adapter 1806, network adapter 1820, and other I/O devices 1822 can be coupled to system bus 1814. Keyboard adapter 1826 and mouse adapter 1806 are coupled to keyboard 1704 (FIGs. 17-18) and mouse 1710 (FIGs. 17-18), respectively, of computer system 1700 (FIG. 17). While graphics adapter 1824 and video controller 1802 are indicated as distinct units in FIG. 18, video controller 1802 can be integrated into graphics adapter 1824, or vice versa in other embodiments. Video controller 1802 is suitable for refreshing monitor 1706 (FIGs. 17-18) to display images on a screen 1708 (FIG. 17) of computer system 1700 (FIG. 17). Disk controller 1804 can control hard drive 1714 (FIGs. 17-18), USB 1712 (FIGs. 17-18), and CD-ROM drive 1716 (FIGs. 17-18). In other embodiments, distinct units can be used to control each of these devices separately.

[0077] In some embodiments, network adapter 1820 can be part of a WNIC (wireless network interface controller) card (not shown) plugged or coupled to an expansion port (not shown) in computer system 1700. In other embodiments, the WNIC card can be a wireless network card built into computer system 1700. A wireless network adapter can be built into computer system 1700 by having wireless Ethernet capabilities integrated into the motherboard chipset (not shown), or implemented via a dedicated wireless Ethernet chip (not shown), connected through the PCI (peripheral component interconnector) or a PCI express bus. In other embodiments, network adapter 1820 can be a wired network adapter.

[0078] Although many other components of computer system 1700 (FIG. 17) are not shown, such components and their interconnection are well known to those of ordinary skill in the art. Accordingly, further details concerning the construction and composition of computer system 1700 and the circuit boards inside chassis 1702 (FIG. 17) are not discussed herein.

[0079] When computer system 1700 in FIG. 17 is running, program instructions stored on a USB-equipped electronic device connected to USB 1712, on a CD-ROM or DVD in CD-ROM and/or DVD drive 1716, on hard drive 1714, or in memory 1808 (FIG. 18) are executed by CPU 1810 (FIG. 18). A portion of the program instructions, stored on these devices, can be suitable for carrying out at least part of system 100 (FIGs. 1 & 2), method 1600 (FIG. 16), and/or method 3100 (FIG. 31).

[0080] Although computer system 1700 is illustrated as a desktop computer in FIG. 17, there can be examples where computer system 1700 may take a different form factor (e.g., a mobile electronic device, a laptop computer) while still having functional elements similar to those described for computer system 1700. In some embodiments, computer system 1700 may comprise a single computer, a single server, or a cluster or collection of computers or servers, or a cloud of computers or servers. Typically, a cluster or collection of servers can be used when the demand on computer system 1700 exceeds the reasonable capability of a single server or computer.

[0081] Returning again to FIG. 2, virtual port 206 and/or the virtual port computer system can be configured to permit the user(s) to pair user interface 111 (FIG. 1) with KVM switching device 101 (FIG. 1) and to configure the manner in which user interface 111 (FIG. 1) controls KVM switching device 101 (FIG. 1) and the respective host computer system(s) 102 (FIG. 1), as a result.

[0082] To begin with, upon turning on KVM switching device 101 (FIG. 1), KVM switching device 101 (FIG. 1) can be configured to detect whether user interface 111 (FIG. 1) is presently coupled with KVM switching device 101 (FIG. 1). If KVM switching device 101 (FIG. 1) detects user interface 111 (FIG. 1) is not presently coupled with it, KVM switching device 101 (FIG. 1) can be configured to switch to virtual port 206 and virtual port 206 can be configured to route switching device audio-visual data from virtual port 206 (e.g., from the virtual port computer system) to control terminal 113 (FIG. 1). The switching device audiovisual data can instruct the user(s) to couple user interface 111 (FIG. 1) to KVM switching device 101 (FIG. 1) and can be presented by control terminal 113 (FIG. 1) (e.g., via audio-visual display device 114 and/or the speaker(s) of control terminal 113). FIG. 3 illustrates exemplary switching device audio-visual data instructing the user(s) to couple user interface 111 (FIG. 1) to KVM switching device 101 (FIG. 1). As an example, this switching device audio-visual data can be presented to the user(s) on audio-visual display device 114. When KVM switching device 101 (FIG. 1) detects user interface 11 1 (FIG. 1), KVM switching device 101 (FIG. 1) can proceed to pairing with user interface 111 (FIG. 1).

[0083] After coupling with user interface 111 (FIG. 1), KVM switching device 101 (FIG. 1) can be configured to detect whether user interface 111 (FIG. 1) is presently paired with KVM switching device 101 (FIG. 1). If KVM switching device 101 (FIG. 1) detects user interface 1 11 (FIG. 1) is not presently paired with it, KVM switching device 101 (FIG. 1) can be configured to switch to virtual port 206, and virtual port 206 can be configured to route switching device audio-visual data from virtual port 206 (e.g., from the virtual port computer system) to control terminal 113 (FIG. 1). The switching device audio-visual data can instruct the user(s) to enter a code presented at user interface 111 (FIG. 1) to pair KVM switching device 101 (FIG. 1) and user interface 111 (FIG. 1). This switching device audio-visual data can be presented by control terminal 113 (FIG. 1). FIG. 4 illustrates exemplary switching device audio-visual data presented or displayed at audio-visual device 114 and instructing the user(s) to provide the code presented at user interface 111 (FIG. 1). Meanwhile, user interface 111 (FIG. 1) can present user interface audio-visual data at user interface 111 (FIG. 1) where the user interface audio-visual data can comprise the code for pairing user interface 111 (FIG. 1) with KVM switching device 101 (FIG. 1). FIG. 5 illustrates exemplary user interface audio-visual data comprising the code presented at user interface 111 (FIG. 1).

[0084] The user(s) can provide the code (e.g., as command data) to control terminal 113 (FIG. 1) via peripheral input device(s) 117 (FIG. 1) and/or the user interface input(s) of user interface 111 (FIG. 1). For example, the user(s) can enter the code via computer keyboard 115 (FIG. 1) and/or mouse 116 (FIG. 1), as would be the case where the code resembles the code in FIG. 5, or can enter the code as some particular provided sequence of the user interface input(s) of user interface 111 (FIG. 1). FIG. 6 illustrates the user(s) providing the code to control terminal 113 (FIG. 1) via the user interface input(s).

[0085] When the user(s) incorrectly provide the code presented at user interface 111 (FIG. 1) to KVM switching device 101 (FIG. 1) via control terminal 113 (FIG. 1), virtual port 206 can provide updated switching device audio-visual data at control terminal 113 (FIG. 1) notifying the user(s) that the code has been incorrectly entered and needs to be entered again. If the user(s) provide a wrong code multiple times (e.g., ten times), virtual port 206 can again provide updated switching device audio-visual data notifying the user(s) to contact an administrator and/or a manufacturer of KVM switching device 101 (FIG. 1). FIG. 7 illustrates exemplary switching device audio-visual data notifying the user(s) that the code has been incorrectly entered and needs to be entered again. FIG. 13 illustrates exemplary user interface audio-visual data notifying the user(s) to contact the administrator and/or the manufacturer.

[0086] When the user(s) correctly provide the code, KVM switching device 101 (FIG. 1) can erase its memory storage module(s) of any previously paired user interface (e.g., previous configuration settings, codes, flags, etc.). The KVM switching device 101 (FIG. 1) can then be paired with user interface 111 (FIG. 1).

[0087] After pairing with user interface 111 (FIG. 1), KVM switching device 101 (FIG. 1) can be configured to detect whether user interface 111 (FIG. 1) is presently configured. If KVM switching device 101 (FIG. 1) detects user interface 111 (FIG. 1) is presently configured, KVM switching device 101 (FIG. 1) can be configured to switch to a predetermined physical port of physical port(s) 102 (e.g., physical port 202 (FIG. 2)). If, instead, KVM switching device 101 (FIG. 1) detects user interface 111 (FIG. 1) is not presently configured, KVM switching device 101 (FIG. 1) can disable the user interface input(s) of user interface 111 (FIG. 1) until completion of the configuration of user interface 111 (FIG. 1), and virtual port 206 can present switching device audio-visual device at control terminal 113 (FIG. 1). Meanwhile, user interface 111 (FIG. 1) can present user interface audio-visual data notifying the user(s) that user interface 111 (FIG. 1) is nearly ready for use and/or to configure user interface 111 (FIG. 1) at control terminal 113 (FIG. 1) (e.g., via peripheral input device(s) 117). FIG. 8 illustrates exemplary user interface audio-visual data notifying the user(s) that user interface 111 (FIG. 1) is nearly ready for use and to configure user interface 111 (FIG. 1) at control terminal 113 (FIG. 1).

[0088] For purposes of configuring user interface 111 (FIG. 1), the switching device audiovisual data present at audio-visual display device 114 can comprise a configuration module configured to permit the user(s) to configure the manner in which the user(s) desire user interface 111 (FIG. 1) to control KVM switching device 101 (FIG. 1) and/or host computer system(s) 102 (FIG. 1). FIG. 9 illustrates an exemplary configuration module displayed at audio-visual display device 114 (FIG. 1). The configuration module can comprise one or more graphical user interface (GUI) inputs by which the user(s) can configure user interface 111 (FIG.

1) . The configuration module can permit the user(s) to select which physical port(s) 207 (FIG.

2) are presently, or desired to be, active (e.g., via a check box input). The configuration module can also comprise one or more check boxes indicating whether any of the host computer system(s) 102 (FIG. 1) coupled to physical port(s) 207 (FIG. 2) require CAC access. Likewise, the configuration module can also comprise one or more drop down lists for selecting names and/or colors for each of physical port(s) 207 and/or host computer system(s) 102 (FIG. 1). Finally, the configuration module can also have a GUI input (e.g., a "Done" button) by which the user(s) can affirm that he/she/they are done configuring user interface 111 (FIG. 1).
