2.4.4 Main Control Board Serial Port ID Description
You can use the jumper cap on the main control board to switch the interface communication
mode. For details about switching between RS-232 and RS-485 communication type, see Switching
RS-485/RS-232 Mode.
Figure 2-9 Main Control Board
According to the picture above, the RS-485 serial port corresponds to UART2 and UART3. RS-232
serial port is corresponded to UART7 and UART8. Wiring Interface is corresponded to UART1,
UART4, UART6, UART6, and Lane.
The main control board descriptions are as follows:
UART2/UART3 Jumper Cap
Reserved serial port. Use the jumper cap to switch the serial port communication mode. You
can switch between the RS-485 communication mode and the RS-232 communication mode. By
default, it is in RS-485 communication mode.
UART6 Jumper Cap
Use the jumper cap to switch the serial port communication mode with the slave lane
controller. You can switch between the RS-232 communication mode and the RS-485
communication mode. By default, it is in RS-232 communication mode.
UART5 Jumper Cap
Use the jumper cap to switch the serial port communication mode with the slave 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.
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.
