I decided to download the software and make some programming changes on my DTR550s. The cable was the one sent for my Nextels years ago. It has the number 04292-0091655 on it. When I use the software, it reads the DTR 550, but when I go to write back to the DTR 550, I get the message:
Communication Error
For RM and RMM Series radio, please toggle the USB cable to ANALOG (CPS) mode.
For DLR Series radio please toggle the USB cable to DIGITAL (Flash) mode.
What should I try next?
AFAIK, the only CPS cable that works with the DTR radios is one like this one. They are available at lots of places.
Thank you for the reply. I was just reading your blog post about these, which helped put everything in perspective.
I looked a bit closer at my cable and it is marked NNTN5970A. When I was a Nextel customer, it was sent to me to update some of those devices. Even though the connector works with the DTR 550, I am not sure if I can use it for anything.
Glad it helped!

Probably not.
As you’ll see as you read more here, sometimes these cables can be frankensteined into flash cables.
