The Levelmaster commands are based on the following syntax:
•
Capital letters are at the beginning of certain data fields
•
Small letters stand for data fields
•
All commands are terminated with "<cr>" (carriage return)
•
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
