Ports changed independently?

As the symptoms don't make much sense for PWM control, I'm presuming that you're using Talon SRXs controlled through CAN.

What did you do with the

"No problem, let's fix that", and we did.

?

Best guess:

It sounds like the Talon SRXs were never given addresses, or given duplicate addresses. The directions to detect and correct this is given in section 2.2 (pages 16 and 17) of the Talon SRX Software Reference Manual. Note that it is necessary to refresh the browser after changing the address; failure to do this caused us some unnecessary confusion the first time we did it. We now do a refresh following each assignment; possibly overkill, but better than confusion.
