RS485

AIBOX-PRO has one RS485 interface. If the CPU is RK3588, the device name is /dev/ttyS6; if the CPU is RK3576, the device name is /dev/ttyS3. It supports half-duplex communication, and the default baud rate is 9600. This interface uses a Phoenix terminal block, so a compatible terminal connector is required. Once connected, it can be debugged using standard serial port methods.
