UART6 Jumper Cap

Use the jumper cap to switch the serial port communicaon

mode with the sub 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.

UART5 Jumper Cap

Use the jumper cap to switch the serial port

communicaon

mode with the sub lane controller. You can switch between the
