(1) Default baud rate: 9,600 bps, check bit: none, data bit: 8 bit, stop bit: 1 bit
(2) Interface type: RJ45, communication power supply output specification: 5VDC/200mA
(3) The RS485 communication line sequence is defined as follows, with interface integrating
remote switch interface (SW1/SW2) and CAN communication interface. When the switch
interface (SW1/SW2) is floating and open circuit = OFF mode; when the switch interface
(SW1/SW2) is short-circuited = ON mode.
