The Unit ID Number is used strictly for communication purposes; it can take any value from 1 to 247. Only
one master can exist in each loop.
Note: Do not duplicate the Unit ID number in a single communication loop!
This situation will lead to response collisions and inhibit communications
to units with duplicate ID numbers.
