Thanks for checking Carl.

Yeah, tried that.

The guys at Martins are going to ask Meridian, the only thing we can think of is the comms address is different for the AC200 compared to the other controllers.

What is the bridge cable needed on the C5 end of a master cable for when using an AC12 with legacy speakers?

I'm trying to think what that actually does.
The pin 5 to ground.

I have jumpered pin 1 to pin 5 on the 180 speaker end, but obviously can't do the jumper on the C5 end as I just have the master and ground.

No Darling, I've had it months!
