Multiport BliSwitch v2 (8-port)
BliSwitch v2 8-port KVM+ATX switch
The BliSwitch v2 is an 8-channel KVM+ATX switch for 8 hosts to share input and power.
Function: 8 hosts share a keyboard, mouse, and display, with power control for all.
Switch Method: Button or USB control. BliSwitch v2 works on its own, but for KVM-Over-IP it needs BliKVM or other KVM.
"BliSwitchv2 Introduction"
"BliSwitch v2 Power Supply Logic"
In addition to the power supply port, the v2 can also be powered via USB from the connected controlled PCs. The specific port providing power depends on which port has the higher voltage. When using the v2 with a KVM, if you notice abnormal behavior such as the KVM restarting during switching or external keyboards malfunctioning, it indicates that one of your controlled PCs is powering the KVM. To prevent this issue, you need to add a USB splitter board to the KVM's USB-PC port.
Features
- ATX on each port(support button and remote control)
- Full control via web ui
- Compatible with BLIKVM V1, V2, V3 V4 and PikVM hardware.

Control Protocol
"If you want to use Blicube's switch on other platforms, please refer to the following protocol"
- Communication baud rate is 19200
- The message to switch to channel 1 is SW1\r\nG01gA
- The message to switch to channel 2 is SW2\r\nG02gA
- The message to switch to channel 3 is SW3\r\nG03gA
- The message to switch to channel 4 is SW4\r\nG04gA
- The message to switch to channel 5 is SW5\r\nG05gA
- The message to switch to channel 6 is SW6\r\nG06gA
- The message to switch to channel 7 is SW7\r\nG07gA
- The message to switch to channel 8 is SW8\r\nG08gA
- The message returned by the switch for the current channel is: G01gA, G02gA, G03gA, G04gA, G05gA, G06gA, G07gA, G08gA
Software Configuration
"If you are using BliKVM software, from version 1.5.3 onwards, power on the switch and connect the cables before starting BliKVM, then enable and configure it through the web interface."
- If multiple USB devices are connected, use the command
ls /dev/ttyUSB*to identify the switch's device name, then configure it through the web interface.
"If you are using PiKVM software, the configuration for Raspberry Pi versions (v1, v2, v3) and the Allwinner-based v4 version is slightly different, with v4 having additional ATX configuration."
v4 usage demonstration
- Modify xh_hk4401.py to support 8 channels
Modify /usr/lib/python3/dist-packages/kvmd/plugins/ugpio/xh_hk4401.py
https://github.com/pikvm/kvmd/blob/master/kvmd/plugins/ugpio/xh_hk4401.py#L90 need to be changed from 3 to 7 also
https://github.com/pikvm/kvmd/blob/master/kvmd/plugins/ugpio/xh_hk4401.py#L175 change [1-4] to [1-8] (used to get which input switch is on)
https://github.com/pikvm/kvmd/blob/master/kvmd/plugins/ugpio/xh_hk4401.py#L185 change channel <= 3 to <= 7 (used to change inputs)
You can directly download and replace xh_hk4401.py 2. For Raspberry Pi versions (e.g., BliKVM v1, v2, v3), /etc/kvmd/override.yaml configuration
