At this point, what I would do is take a PWM signal generator and plug that straight into the Jaguar and see what happens then. I'll assume you don't have something like that on hand, however, so here are your options right now:

Swap out the Jaguar for something else that has been proven to work, such as a Victor or servo (in the case of the servo, remember to toss a jumper on the pins next to the PWM output). If it still doesn't work*, try switching the PWM channel, e.g. from 1 to 10, or if possible, use a channel that has been proven to work (in Colonel's case, try using an output from last year's DS). In my experience, there are rare occasions where, for some unknown reason, a DS output will not work, and using a different output channel will remedy the situation.

*By work, you should also ensure that the response varies with respect to input - i.e. for a Victor, turn green on forward and red on backwards.

If you have a multimeter available, measure the voltage (DCv) across the black and red pins (center and darkest color) at the Jaguar's end of the PWM; the reading should be +-5V (the reading should only be negative if you're reading voltage backwards).

Another approach you could attempt is setting up the serial-RS45 connector and attempting to configure the Jaguars themselves. If this fails (assuming you've done the process correctly) - you'll be able to tell if some Jaguars respond and others don't, or if you've followed every step to the letter and none of them respond - then it's a possibility that your Jaguars themselves are bad, in which case you'll need a replacement.

In short, what you want to do is isolate the problem by removing each and every variable from the problem - use stuff that you know works, so that it becomes a controlled variable.
