RSP Address
Each Line Unit is assigned to a RSP address
The RSP address is unique within the Comport
The RSP address is the same for Line Unit A & B side
Every node in a RCS system must have an address
The RSP address is within range 1 .. 255. Typically the
following intervals applies:
[1..127] RTU lines
[128..199] Emulator lines
[200..255] Master Lines
