Communication parameters Description
Baud rate 9600
Data bits 8
Check bit None
Stop bit 1
Start bit 1,one frame command finished, using CRC to check
Function code Inquiry: 03H. Control: 06H/ 10H
Unit address 1-32
START b1 b2 b3 b4 b5 b6 b7 b8 STOP
Start bit Data bit Stop bit
2. Data frame format definition
Device address Function code Data CRC verification
8 bits 8 bits N*8bits 16 bits
Attention: In order to avoid data detection errors caused by the frame length being too long, the total length of a
data frame in query, setting, and response is controlled within 50 bytes.
