MODBUS communication is divided into two encoding modes which are namely
RTU and ASCII, here code is directly transmitted according to RTU mode,
character structure: 11-bit, which could be any of the following 2 formats. For
detailed selection mode, please see parameter table.

Communication data frame structure (RTUmode)
GT610/GT620 communication data frame format adopts RTUmode, and data
format is as follows:
10ms Interval
+ Slave Computer Address + Function Code + Detail Data + CRC CHK +
10ms Interval
Length: 2 bytes
Length: Multiple bytes
Length: 1 byte
Length: 1 byte
The following table is an intuitive expression of list form:
STX
Keep no-input signal larger than or
equal to 10ms.
