UART1 Jumper Cap: Use the jumper cap to switch the serial port communication
mode with the master lane controller. You can switch
between the RS-484 communication mode and the RS-232
communication mode. By default, it is in RS-485
communication mode.
Lane: Use the jumper cap to switch the serial port communication
mode with the lane controller. By default, the interface is
wired and it is in RS-485 communication mode.
If wiring other controllers (compatible with Hikvision
communication protocol), use the jumper cap to switch
between RS-485 and RS-232 communication mode.
UART4: The serial port is in the wiring interface according to the
picture above, which has a fixed RS-232 communication
mode to communicate with the master lane controller. It
contains no jumper cap and cannot change the
communication mode.
UART7/UART8: Reserved serial port. The serial port has a fixed RS-232
communication mode. It contains no jumper cap and cannot
change the communication mode. It can connect QR code
