It -really- can't be this hard...

The Service manual for the R100 is at http://www.repeater-builder.com/motorola/r100/uhf-r100-service-manual-6881078e15-o.pdf

On page 58 is the output of Jaux

I'm using pins
14 - gnd
15 - spk hi
16 - Mic hi
17 - Mic gnd
18 - PL monitor (active low)
19 - PTT (active low)

Corresponding Pins on the DMX URI ~should~ be (I would think)

URI            R100 Jaux
1     PTT    19 PTT
8     COR   18(*) PL Monitor
24    Ain    15 Spk Hi
12    Aout  16 Mic Hi
13    gnd   17 Mic gnd
13    gnd   14 gnd

So... when I plug it in, the R100 keys up, and running radio-tune-menu, nothing works.

(* = I use COR for PL monitor, because my R100 uses DPL (DCS) and not CTCSS.)

Thoughts?
