[Toa Circuit]

I actually did this for our driverstation this year, only used a Jaguar. We had tried a Victor 884 (Which never worked with our cRIO fully; the victor is very silly, we got it to work a few times... otherwise it does weird things.) to no success except one instance of calibration.
A few things:
1. Check that your wiring is correct. There is a skematic on this page which is full of doing somewhat what you want right now (Jag instead of victor; but they work the same(ish)), verify that it is the same: http://circuittech.tumblr.com

2. Check the victor indicator light. Is it blinking orange as if it is unsignaled? Is it solid orange, as if there is a signal, but not a signal to move? Knowing this would help us more.

3. The 5V pin running to the victor/jaguar is unneeded. Save yourself a little wiring chaos (Shorts from pins being close) and don't wire it up.

4. What is your code? You sure you're doing everything right?
