3.3.2 Configure RS485 sensors
Some sensors might need to configure before normal operation. User can configure such sensor
via PC and RS485 adapter or through RS485-LN AT Commands AT+CFGDEV. Each AT+CFGDEV
equals to send a RS485 command to sensors. This command will only run when user input it and
won’t run during each sampling.
AT Commands Description Example
AT+CFGDEV This command is used to configure the RS485
devices; they won’t be used during sampling.
AT+CFGDEV=xx xx xx xx xx xx xx xx xx xx xx xx,m
m: 0: no CRC, 1: add CRC-16/MODBUS in the
end of this command
AT+CFGDEV=xx xx xx xx xx xx xx xx xx xx
xx xx,m
