First time posting so go easy on me. I've searched AVS archives and googled for an hour or 2 without finding much that was helpful.
Got a new to me house (~4.5 YO) and am trying to trouble shoot the installed Legrand/ABus/OnQ multi room audio system, which is fed by my AV system and drives in-ceiling installed speakers in different rooms.
Basically the system consists of an A-Bus source Input Unit.
Which is fed by my AV system via an RCA jack cable. The input unit feeds via cat 5 an OnQ A-Bus 4 zone distribution hub.
This feeds, via cat 5, the speaker control ABus keypad in the individual rooms. The room's speakers are hardwired to these keypad.
The problem is that one of the keypads doesn't work - doesn't power on, no sound from speakers. The other does. The problem one doesn't light up when I push the power button. If I had a schematic of the keypad I could check the input power - which I believe is 24vdc. Then I could see if the keypad is at least getting power.
Anyone know anything about this stuff or have some other troubleshooting methods? The only test equipment I have is a volt/ohm meter. I'd like to do some swapping around of connections the problem with that being that the cat-5 cable is terminated at punch-downs and I don't have any tools for that
I suspect that the keypad is bad, but for all I know the cat-5 wire feeding the keypad is damaged.
Thanks for your thoughts.
BTW - I could not post my url links showing the involved devices. Something about "You are only allowed to post URLs once you have at least 3 posts." I'll see if I can post them below.
