CDM Programing Cable Question

[rydzewski]

I'm going over the schematics to build this cable..

I saw that you need a flash adapter to update the firmware. My question is, Can I just add a Switch to my cable (linked above) to connect DB-25 pin 1 to pin 25?

Sure, you can.

Thank You

Ok... Now im lost...

Here is the cable I made... following the batlabs diagram and removing the test set part.

DB 25 20pin on radio

1--------------------7
4---| -connected pin 4-11 on db25
11--|
12------------------13
15------------------17
25------------------18

I also installed a switch that connects db 25 pin 1-25. When I try to read the radio from the accessory port it shows data on the rib, then tells me to check the connections. If i try my mic programing cable it works fine...I'm trying to flash my radio with a built in switch for the cable.. any insight would be appreciated

Thank you.

If you're trying to upgrade the firmware:
1. Switch on your cable to off position
2. Start firmware upgrade kit software
3. Set switch to on on your cable, reset power as instructed on CDM
4. Click 'OK' on popup window to start reflash

At which step above are you encountering trouble?

my issue is the cable wont even read the radio... i cant open it in cps, or the firmware tool.

I just checked the pinout that you listed against my AARKN4083 cable, and your information is correct, Ben. Remember, the connector on the rear of the CDM is 20 pin...pins 1 & 20 are adjacent to 1 & 2. If you're using a 16 pin connector to plug into the rear of the CDM, you have to make adjustments to account for the listed pinout vs. actual pin numbering on your cable's connector.

Maybe it's the pins on the back.... I have a 20-pin connector i got off eBay. on it it says 2 10 20 on the top of the connector.. so i went from left to right counting up.. so bottom left is 1, upper left is 2, then lower 3 upper 4 and so on.... is this correct... if not then there's the problem!

[Al]

Viewed from the front(pin end) of your connector with the locking tab at the top, M labels the pins as: 19, 1,3,5,7,9,11,13,15,17 on the top row. Bottom row is: 20, 2,4,6,8,10,12,14,16,18 left to right viewed from the pin end.

yeah i saw that online. i tried that as well. i think i might just go buy the cable tomorrow and make life easier. thanks for all your help.
