Not if he wants to control 2 CT's from an XP-8.
1 driver controls zones A-F on CT #1
2nd driver controls zones A-F on CT #2
My point was maybe lexiphanic has one or both of his CT units that currently are set on a different code set (ie codeset 21-26). Therefore one way RS232 would work but the driver control wouldn't.
