Check out the manual on the Jaguar here:

On page 9 is a diagram detailing all of the inputs and outputs from the Jaguar, and the "Limit switch inputs" are on the bottom right. There are 4 pins there. Put a jumper connecting the two on the left to allow forward movement, and a jumper on the two on the right to allow reverse movement.

These pins allow you to hook up normally-closed limit switches so the motors will automatically turn off when pressed - for example, when an arm reaches a maximum limit. To use that feature the FIRST rules state you need to use the CAN bus instead of PWM control... however missing a jumper will prevent the Jaguar from turning in that direction.


If you aren't sure if your missing one, or if your Jaguar is hooked up correctly, please post a picture of it so we can take a look.
