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.

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 Corey N3FE ________________________________________ From: app_rpt-users-bounces@ohnosec.org [app_rpt-users-bounces@ohnosec.org] On Behalf Of Steve Agee [n5zua@earthlink.net] Sent: Wednesday, June 05, 2013 1:13 PM To: Geoff Cc: app_rpt-users@ohnosec.org Subject: Re: [App_rpt-users] DMK URI to Motorola R100 What is presently on the line to pull low?

The URI(x)Cor line requires a transition from Hi Impedance(open) to ground. It does not require voltage to be applied. So if your radio is supplying a voltage change by sourcing a logical hi like 5 V when cor is active and but the voltage is not grounded when "low" then the URI will not see a change. So if your radio does not pull the line all the way to ground then you could use a resistor and NPN transistor to pull the cor line low for the URI. Having said that, I'm sure the radio can be configured to give an active low output to drive the URI directly. Jon On 6/5/2013 7:48 PM, Corey Dean wrote:

Turns out - it really wasn't. Thought I'd let you folks know that the node is up and running. I wound up with DMK URI R100 J(aux) 1 - PTT 4 8 - COR 25 (after a mod for Carrier Detect) 13 - GND 1 19 - GND 6 21 - Mic_in_AC 15 Spkr 22 - Left Out 16 Mic Hi I'll be the first to admit, it was cock-pit error, mostly... but there were a couple of issues that had to be overcome first, that and a couple of .conf files that were 'tweaked'... Mostly it was trying to re-train my brain to count backwards on the DB-25's. Then, the Jaux plug on the R100 is upside down(!) So, 1 starts on the left, and reads right... but it starts at the Bottom... guess the ol' brain is simply getting old ~sigh~ I still say I'm an analog guy, in a digital world. Give me a couple of mercury vapor rectifiers and 3 triodes, and I'll wind up an ol' AM transmitter! These 3-legged devils and one-way wires and 40-legged craptastic monsters you can't see with a good microscope (let alone solder to one of it's itty-bitty legs!) just ain't my cup o' tea... but, hey... when you want a link you can rely on from Houston to San Antonio so you can talk to your mom, via ham radio... you do what you have to. 73, y'all -Geoff
