•
All commands start with "Uuu", whereby "uu" stands for the address (00-31)
•
"*" can be used as a joker for any position in the address. The sensor always converts this in
its address. In case of more than one sensor, the joker must not be used, because otherwise
several slaves will answer
•
Commands that modify the instrument return the command with "OK“. "EE-ERROR" replaces
"OK" if there was a problem changing the configuration
