It should be noted that, in some cases, if the computer management device 22 to which the control module 28 is connected already has an analog digital converter, the analog converter 287 of the control module 28 can be omitted, that is, the computer management device. The digital image 'image nickname' output by 22 can be directly processed by the processor 288. The computer official device 22, which already has an analog-to-digital conversion, can be a KVM-Over-IP, such as provided by Acer Automation Technology Co., Ltd. • CN6000, CN8000 'KH1508i, ΚΗ1516Ϊ, etc. product. Under the control of the second peripheral device controller 286, an analog video signal (for example, a VGA video signal) output by a controlled computer 24 is transmitted by the switching device 23 in the computer management device 22 by the control module 28 The VGA connection of the second communication interface 282 is received by the state 2824 (as shown in FIG. 4A or FIG. 4B). The analog digital converter 287 then converts the analog video signal received via the second communication interface 282 into a digital video signal and outputs it to the processor. The processor 288 causes the digital video signal generated by the analog-to-digital converter 287 to be converted and encoded into the image of the USB signal format 201122823 signal 'and transmitted under the control of the first peripheral device controller 284 through the first communication interface 280 and the USB Connector calendar (as shown in Figure 4A (4) format image 麟 it 到 到 到 到 2.6. ^ ^ On the other hand, in this embodiment, the central control computer 26 is installed with a management program and has - USB host controller (not shown Show), the management program Ap can convert the control signal sent by the computer 26 (such as the cursor generated by the mouse or the keyboard or the simple word or letter) to the format of the coffee signal. . The first peripheral device controller 284 is relatively a controller device, and the control device issued by the central control device 26 can be employed by the first communication interface 28 of the control panel 28 (four) Cong connector (as shown in FIG. 4A). Or received as shown in the first offence. The receiver transmits the control signal to the controlled power = 4 via the second communication interface and the USB connector 2822 (as shown in FIG. 4A) under the control of the second peripheral device controller 286.
