Does anyone know if the RS-232 control connection for the monitor port connected with display one can operate a Panasonic PT-AX100U lcd projector? I’m only looking for on and off control.

BeoSystem 3 and Panasonic projector

Or perhaps asked another way - does anyone know if the RS-232 connection is generic enough that another tv/monitor/projector will accept the issued commands from the BeoSystem 3? If so, it could give my theater system an easier integration by keeping the IR signals in the equipment closet and route a comm cable to the ceiling projector. I would appreciate anyone’s experience here.
I found an outfit that will custom order a one-off cable for me for about $65. Before I waste my time (I may have already wasted my money), does anyone know if this will work?
With you using this as the main screen, I think you’ll be OK.
The protocol looks the same, and the serial port speed is the same. On/off commands and prefixes are the same (PON/POF) The only difference is the plug on the projector.
although not having tried it, so caveat emptor! Note that you need to tell the Beosystem 3 that you are using a B&O monitor so it will send commands through the serial port. Choose a relatively early display (with the correct resolution) to minimise all the extra commands the Beosystem 3 will send.
I’ve never used a projector, but if you choose one that can be switched on/off with HDMI-CEC, then you can do this with a serial cable and a raspberry PI. that’s how I drive a couple of Beosystem 3s with a LG and Samsung (respectively) monitor attached
I’m hoping the custom cable I ordered will be able to control the projector directly. I’ll see what happens next weekend, after it comes in. I don’t think the projector has HDMI-CEC control.
So here’s my stupid question of the day - can I just plug a mono cable between the BeoSystem 3 control output and the Oppo Blu-ray player IR input? If so, do I set it for IR or Plug?
If you have the PUC, set it for plug with no modulation
Thanks, that’s great information and will lead to a much cleaner installation, with less dangling wires.😁If you have the PUC, set it for plug with no modulation
I tried connecting a stereo cable instead of a mono cable, changed to “plug without modulation” and it did not provide control. I’ll buy a mono cable soon and try again.I’ll note the PUC, when used with IR, can provide control to a point. It will turn the Oppo off, skip tracks, pause and play, but will not turn it on. Any ideas?
