Name Excitation Voltage Output command
Description Send a value to the analog output channel of the addressed
strain gauge input module. Upon receipt, the analog output
channel will output this value.
Syntax $AA7(data)(cr)
$ is a delimiter character.
AA (range 00-FF) represents the 2-character hexadecimal
address of the strain gauge input module.
7 is the Excitation Voltage Output command.
(data) is the value that has to be output through the analog
output channel. The data format is engineering unit and the
range is between 0 ~ 10 V.
(cr) is the terminating character, carriage return (0Dh)
Response !AA(cr) if the command is valid.

Example command: $337+05.000(cr)
response: !33(cr)
The command sends the value +05.000V to the analog
output channel of the strain gauge input module at address
33h. The module responds that the command is valid. Its
output data format is in engineering unit, the value is +05.000V.
