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
1. 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)
