[App_rpt-users] DMK URI to Motorola R100

I went directly inside and soldered directly to where I needed things.  Very simple to do.  I do not use Cor.  I let the USB FOB, do the PL decode for me.  Mine was also DPL but I programed it without a DPL and let the USB Fob encode that was well

What is presently on the line to pull low?  In other words, do you need to
add a voltage line with a 10K pull up resistor to give it something to pull
low to start with? A VOM will tell you.

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?
