Re: Crio-Sidecar

We are using 4 wheel drive, and after much trouble shooting we are certain it is not the code. We have figured out though, if you unplug any of the two jags the problem goes away. One other thing we have noticed is that if we toggle the disable/enable button after it stops working the 5v light turns on again, but the same problem will occur. My team doesn't know where to go with this, any help is very much appreciated. The first thread started out in programming because we originally thought it was a code issue.

Sounds to me like your battery is low. When you draw high current from your 4 cims the battery voltage will drop. If the battery voltage is too low then the cRIO will go into protect and disable everything until the voltage rises again.
