Unit Address
The Unit Address is a number that uniquely identifies the controller. It is
typically embedded in communications telegrams so that each GCM knows
who is to respond to which telegram. The lowest address is always one (1), and
the highest depends on the protocol selected. The default address is 1, but this
may change if there are multiple controllers connected to one network or serial
communications bus (i.e. RS-485).
If multiple Genetix GCM's are connected to one Genetix Color User Interface,
each GCM must have a sequential Unit Address, starting at one (1).
If multiple Genetix GCM's are connected to one network protocol converter,
each GCM must have a uniquel Unit Address, but they need not necessarily
start at one (1), although this is typically the case.
The Unit Address is port and protocol specific. For example, it is possible to
have a Unit Address on port 1 that is different from the Unit Address on port 2,
along with different protocols.
