APX6500 Mobile O-7 Multiple Control Head Addressing

[JeffFireRadio]

I've been doing this on XTL5000s and O-5s forever, but how do you address an O-7 control head as #1, #2, etc. on an APX mobile? The fire chief wants to add a second O-7 remote head to his already single O-7 remote head APX6500 for rear-of-the-vehicle purposes. The old hold-down-a-button-and-then-power-on option doesn't seem to be the process for the APX. A CPS-only thing? Auto configure? Do tell. Thanks.

Are you getting some sort of error when the two heads are connected?

As far as I'm aware, you use CPS.

No, just can't get into 'assign control head number' mode on the standalone control head. I might have found some documentation within the last minute or two. I don't think I was using the correct button hold sequence before powering on. I'll give this new process a try. Thanks.

Left most Menu Select button and Emergency while powering on. Wasn't sure that you needed to do that for the APX but apparently it's still a thing.

Yep, the left button plus emergency button is still a thing even with the E5 head. The BK KNG Series has a similar function, why they cant simply generate their own addresses on the data bus on power up is beyond me...

I wasn't getting the emergency button into the sequence. My outstanding memory must be declining. Darn. Thanks all.
