Embodiment Construction

[0014] see figure 1 and figure 2 , is the multi-computer switching system 100 of the preferred embodiment of the present invention, comprising a KVM switch 10, four computer hosts 20, four sets of KVM switch cables 30, a display 40, a keyboard 50, a mouse 60, and a Root console VGA cable 70.

[0015] The KVM switch 10 includes a front 101 and a back 102 opposite to the front 101 . Four switching switches 1011 are arranged on the front side. The back side 102 is provided with four sets of connection ports 1021 and one set of control ports 1022 . Each group of connection end interfaces 1021 corresponds to one switching switch 1011 . Each group of connecting port interfaces 1021 includes a first VGA interface 1021a and two first universal serial bus (universal serial bus, USB) interfaces 1021b. The console interface 1022 includes a second VGA interface 1022a, two second USB interfaces 1022b and two PS / 2 (personal system 2) interfaces 1022c.

[0016] Each host computer 20 i...

Abstract

A video graphics array (VGA) cable comprises a first VGA connector, a second VGA connector, an indicator lamp and a transmission line for joining the first VGA connector and the second VGA connector. The first VGA connector and the second VGA connector a re respectively connected to a multi-computer switcher (kernel-based virtual machine (KVM) switcher) and a computer host. The first VGA connector comprises an insulation main body and 15 pins which are stored inside the insulation main body. The 15 pins comprise one power supply pin which is connected with a power supply and one grounding pin which is used for grounding. The indicator lamp is arranged outside the VGA cable, and two ends of the indicator lamp are respectively connected to the power supply pin and the grounding pin. The computer host transmits an image signal to the KVM switcher through the VGA cable, and the indicator lamp is lightened after being powered supplied by the KVM. Whether the computer host normally transmits the image signal to the KVM switcher or not can be conveniently recognized. The invention also provides a multi-computer switcher system.

Description

technical field [0001] The present invention relates to a cable, in particular to a video image array (video graphic array, VGA) cable and a multi-computer switching system using the VGA cable. Background technique [0002] Currently, a KVM switch (keyboard, video, mouse, KVM switch) is used to connect multiple computer hosts and a keyboard, a monitor and a mouse. A KVM switch has multiple connection ports and multiple switches. Each switch corresponds to a connection port, and each host computer is connected to a corresponding connection port through a VGA cable, that is, each switch controls a corresponding host computer. During use, the operator turns on one of the switches to test whether the host computer corresponding to the turned on switch can output image signals to the display through the corresponding VGA cable and the KVM switch. However, during the testing process, operators often cannot quickly identify which computer host is being tested, resulting in low te...
