Resetting the C-Rio

[Mark McLeod]

If you have a low battery, that can be the cause of your connection problem.
You can test the battery under load by powering up the cRIO, then using a multi-meter on the Power Distribution Panel input power lugs to see that you're getting enough voltage. Assuming it's only powering the cRIO (not any motors), then it doesn't have to read 12v, but shouldn't read less than 8v (and that's really too low).

Don't attempt to re-image if your battery isn't above 10v to be on the safe side. If the power dips too low during imaging, then you'll leave the cRIO in a funky state and have to build the cRIO up from scratch, and without reliable power, it'll never get done.

What kind of manual are you looking for?
If you're just looking for instructions on re-formatting the cRIO, then I can write those up for you.
Getting Started with the 2012 Control System is a good general FRC document to start with.
cRIO-9074_OperatingInstr.pdf are the general cRIO I operating instructions.

You probably don't want to pay too much attention to the standard generic cRIO operating instructions. Some of the information applies, but other directions it gives isn't what you should be doing with our special hardware/software setup of the cRIO for FRC. For instance, the NI standard tool, MAX, probably isn't what you should be using without better expert guidance.
