2.4.4 Main Control Board Serial Port ID Descripon
You can use the jumper cap on the main control board to switch the interface communicaon
mode. For details about switching between RS-232 and RS-485 communicaon type, see S
witching
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 c
orresponded to UART7 and UART8. Wiring Interface is corresponded to UART1,
UART4, UART6, UART6, and Lane.
The main control board descripons are as follows:
U
ART2/UART3 Jumper Cap
Reserved serial port. Use the jumper cap to switch the serial port communicaon mode. You
can switch between the RS-485 communicaon mode and the RS-232 communicaon mode. By
default, it is in RS-485 communicaon mode.
U
ART6 Jumper Cap
Use the jumper cap to switch the serial port communicaon mode with the slave lane
controller. You can switch between the RS-232 communicaon mode and the RS-485
communicaon mode. By default, it is in RS-232 communicaon mode.
U
ART5 Jumper Cap
Use the jumper cap to switch the serial port communicaon mode with the slave lane
controller. You can switch between the RS-484 communicaon mode and the RS-232
communicaon mode. By default, it is in RS-485 communicaon mode.
UART1 Jumper Cap
Use the jumper cap to switch the serial port communicaon mode with the master lane
controller. You can switch between the RS-484 communicaon mode and the RS-232
communicaon mode. By default, it is in RS-485 communicaon mode.
