7.1 Interface Overview
The switch drive supports RS485 communication and uses Modbus-RTU to communicate with our EMS
integrated energy efficiency management system or third-party platform communication protocol.
Default communication settings: address is 001 and port rate is 9600.
7.1.1 Transmission mode
Information transmission is asynchronous, and in bytes, the communication information
transmitted between the host and the slave is in 11-bit format, including 1 start bit, 8 data bits
(the lowest effective bit is sent first), no parity bit, and 1 stop bit.

Address code: The address code is at the beginning of the frame, consisting of a byte (8-bit
binary code), the decimal system is 0~255, and the maximum system can be set to 247. These bits
indicate the address of the user-specified terminal device that will receive host data from and
connected to it. The address of each terminal device must be unique, and only the addressed terminal
