The control chip 30 is configured to control the first multiplexer 10 and the second multiplexer 20 to perform a switching operation at the same time, so that the first computer 1 and the second computer 2 are respectively arranged in two pairs. The serial communication connection is established by signal transmission and reception (details are detailed in Figure 2).

In this embodiment, the control chip 30 is programmed or installed with a software program module, such as a preset module 301, a detection module 302, and a control module 303. The module refers to a program segment that can perform a specific function. The function of each module will be specifically described in the flowchart of FIG. 2.

Referring to FIG. 2, the method for establishing a communication connection between the pair of serial signal transmission and reception of the first computer 1 and the two pairs of serial signal transmission and reception of the second computer 2 by using the peripheral device 100 A flow chart of a preferred embodiment.

In step S1, the peripheral device 100 is respectively connected to the pair of serial signal receiving ports of the first computer 1 and the two pairs of serial signal receiving ports of the second computer 2.

Specifically, the first serial signal receiving port 11 of the peripheral device 100 is connected to the fourth serial signal transmitting port 101 of the first computer 1, and the first serial signal is sent to the first and second serial signals. The fourth serial signal receiving port 102 of the first computer 1 is connected. In other facts, the first serial signal receiving port 11 may be connected to the fifth serial signal transmitting port 111 of the first computer 1, and the first serial signal may be sent to the first and second serial signals. The fifth serial signal receiving port 112 of the first computer 1 is connected. That is, the peripheral device 100 only needs to be connected to the pair of serial signals of the first computer 1.

At the same time, the second serial signal transmission port 21 of the peripheral device 100 is connected to the sixth serial signal receiving port 201 of the second computer 2, and the second serial signal of the peripheral device 100 is received and received. The sixth serial signal transmission port 202 of the second computer 2 is connected, and the third serial signal transmission port 31 of the peripheral device 100 is connected to the seventh serial signal receiving port 211 of the second computer 2, And connecting the third serial signal receiving port 32 of the peripheral device 100 to the seventh serial signal transmitting port 212 of the second computer 2. That is, the peripheral device 100 needs to be connected to the two pairs of serial signal transceivers of the second computer 2.

In step S2, the preset module 301 presets the first multiplexer 10 to turn on the first serial signal receiving port 11 and the second serial signal transmitting port 21, and preset the second multipath. The switch 20 turns on the first serial signal transmission 埠12 and the second serial signal reception 埠22. Then, the first computer 1 establishes a serial communication connection with the second computer 2 by using the peripheral device 100. At this time, the first computer 1 establishes a serial communication connection with a pair of serial signal transceivers formed by the sixth serial signal receiving port 201 and the sixth serial signal transmitting port 202 of the second computer 2.

It should be noted that, in other embodiments, the preset module 301 may also preset the first multiplexer 10 to send the first serial signal receiving port 11 and the third serial signal. The 埠31 is turned on, and at the same time, the second multiplexer 20 is preset to conduct the first serial signal transmission 埠12 and the third serial signal receiving 埠32.

In step S3, the detecting module 302 immediately detects whether the first serial signal receiving port 11 receives the first multiplexer 10 and the second multiplexer 20 sent from the first computer 1. Signal for channel switching. When the signal for switching the first multiplexer 10 and the second multiplexer 20 is detected, step S4 is performed; otherwise, step S3 is continued.

Specifically, when the first computer 1 desires to transmit and receive another pair of serial signals of the second computer 2 (ie, the seventh serial signal receiving unit 211 and the seventh serial signal transmitting unit 212) The first computer 1 can send the signal for switching the first multiplexer 10 and the second multiplexer 20 to the first series when the communication connection is established. The signal is received 埠11. The detecting module 302 can detect the signal for switching the first multiplexer 10 and the second multiplexer 20, and step S4 is performed.

The first multiplexer 10 disconnects the first serial signal receiving port 11 from the third serial signal transmitting port 31, and turns on the first serial signal receiving port 11 and the second string. The column signal transmits the connection of the port 21, and controls the second multiplexer 20 to disconnect the first serial signal transmission port 12 from the third serial signal receiving port 32, and turns on the first The serial signal transmission 埠12 is connected to the second serial signal receiving port 22. That is, the first computer 1 uses the peripheral device 100 to establish a pair of serial signal transmission and reception ports constituting the sixth serial signal receiving unit 201 and the sixth serial signal transmitting unit 202 of the second computer 2 again.

The communication connection between the two pairs of serial signals is saved, and the pair of serial signal transmission and reception resources on the first computer 1 are saved.

In the actual application, for example, the test host described in the background art needs to control the server to perform testing under different hardware systems, because the server main system of the server and the BMC (Baseboard Management Controller) management system share the server. After a pair of serial signals are transmitted and received, the server's SAS (Serial Attached SCSI) controller system and the SAS Expander system share the other pair of serial signals of the server, and the test host can serve as the host.
