We have it connected to the Digital I/O of the digital side car.

Have you wired it correctly? There should be a +5, A, G, and B on the encoder.
PWM 1 - black to G, red to +5, white to A
PWM 2 - black to G, red to +5, white to B

The second PWM cable doesn't really need the ground and power connected. Since you didn't provide enough information, are you sure you connected both the A and B channels and selected the right ones in LabView? (are you using LabView or C++?)
