If the led remains solid after you press the assign button, it is not getting the command for some reason.
Can you down load the Version 92 firmware? Is the temp updating? That would eliminate some possibilities.
Some computer comm questions. Look in system settings is your RS232 port really comm 1? What kind of RS232 port are you using? Do you have another program trying to use the com port. RSlinxs (Allen Bradley & the old Palm software was real bad about that. Do you have a IR port.

Thank you for yet another speedy response!
I can re-check the pins on the RS232 to CAN cable (the next time I'll be able to do so is on Thursday), this is the only thing I can think of that would be the issue, because it's not even updating the temperature.
We have not updated the firmware from factory default, I was afraid that the issue was with sporadic communications, not no communications, and that might risk bricking the jag.
Under the system settings, it used to be that a printer port on the laptop (a very old laptop) was assigned to COM1, we disabled that in the system settings, and forced the com port on the jag to 1, under the software of the usb to serial interface that we use.
When we select "connect" in BDC comm, the status LED on the adapter blinks (it's active), and the software shows it as a "busy" state, all leading me to think that we do have comms, but it must be with wiring. I will also try with another black jag, and see if it's the jag that's the issue, I'll keep you posted
