RS485, CAN Communication Specification & Wiring
RS485 serial port supports MODBUS_RTU protocol and custom communication,
which contains 485A, 485B and public end.
The CAN interface of the controller adopts the standard CAN communication
protocol, which mainly includes three ports, CANL, CANH and the public end. And it can
connect to CAN expansion modules and other standard CAN devices.
