When Setting device id's make sure you use the "Flash LED" command to identify the correct talon srx before setting the id and buss number. Quite common to setting the id to another SRX than the one you wanted.

What did you do with the

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.
Another thing that happens, is that it shows that a talon srx is a pdb and sometimes even a vrm, which gets me even more confused (Image added as example)

And it says in the picture that it's port is number 6, when a second before that happened the port was 1.
