I have a Motorola CDM1550 wired to a Zetron tone remote 250, which is in turn wired to a Zetron tone remote 284, all in the same room as a bit of a lab set up.

Can someone please confirm whether or not I am correct in my assumption that when this set-up is powered up that I should have comms between a (Motorola HT1250) handheld and the tone remote 284 when they both have the same channel selected?

Yes, you should, assuming everything is connected correctly.

Sorry, don't mean to sound snarky or anything, but we've all had brainfarts ocasionaally, right?

The 284 is a 4-line remote, isn't it (been a while)? I forget how it comes up on POR; or don't you have to tell it which lines to automatically select?

2 wire operation? Got the right pair?

And does the CDM1550 RX & TX with the handheld OK?
