Guys - I just had a client add a second CT600.1 for expansion of zones. We had wired it and programmed the 1st unit as serial (RS232). Apparently, when you add the expansion of another unit you MUST use IR only which means i had to reprogram the whole system to IR from serial. All of the tuner direct presets were rs232 listed in the database. They are not listed in the IR database.

I cannot find the zone specific tuner presets. Only thing i have come up with is preset+ and preset-..... any help is appreciated it.
