I kind of get the impression that your word on certain matters is authoritative (you seem to be quite knowledgeable about cRIO hardware for example), but being somewhat new around here, I do not know from whence that authority arises.

Sorry! No offense taken, I'll try to tone it down a bit.

I designed the kit of parts electronics that are encased in blue plastic (PD, DSC, and the breakouts) as well as some of the kit sensor boards (2009 and 2010 Gyro and Accelerometer).

I also did a bit of the architectural legwork before the project really kicked off in earnest. This puts me at a disadvantage, because sometimes I know what it was supposed to do 3-4 years ago, and not what it actually does now. Also, I don't touch software.

You can test the Jaguar limit inputs for yourself (I did) under PWM control.
Simply pull out the jumpers one at at time test Jaguar motion and replace.

It's one of the fault conditions we have people check for when their Jags don't work in one direction or another.

I have no official standing as does Eric however. I just tinker a lot and visit a bunch of teams who's purpose in life often seems to be to break things in interesting and unique ways...

What a great idea. And so easy. Thanks.

If I had more convenient access to the hardware I'd probably start thinking along those lines more often.

My point of course is that testing or other direct experience (sometimes bad experiences) will be the source of most of the answers you find on this forum.

Authoritative answers in the traditional sense, such as Eric's and Greg's, are rare.
