Have you confirmed your wiring matches both the Robot Power Distribution (with correct polarity) and Robot Data Connectivity diagrams, paying particular attention to the power and signal wires to the digital sidecar?
|
Yes

Is the digital module on the cRIO in slot 4 (with 1 being the slot nearest the lights)?
|
Yes

Are the lights green on your cRIO?
|
Yes

Does anything else on the digital sidecar work (PWMs, sensors, whatever)?
|
Yes the entire system works except for the signal light. On the digital sidecar we have 4 victors, 1 spike, 1 sensor, and 2 servos. All work correctly.

If so try switching the two modules and if it still doesn’t work try another 40 pin cable and if it still doesn't work try re-imaging the c-Rio.
|
We have tried 4 modules, 2 40 pin cables, 2 digital sidecars, and 2 cRIOs. We also have reimaged the cRIO numerous times.

Are the three power supply LEDs lit on the sidecar?
|
Yes

|
If not is there a breaker in the PD that is feeding battery to the sidecar?
|
Yes the sidecar is in the 30 amp spot with a breaker
Quote:
|
Have you rechecked the wiring at both the PD and the sidecar?
|
Yes we have rewired the entire system 4 times

If the battery LED is on and the other lights are not, try removing the Robot signal light from the sidecar. If they come on with the RSL removed, you may have shorted the wiring for the RSL. If they do not come on, it is possible that the card is defective.

The 3 power/ battery lights are on the digital sidecar. The Signal light still doesn’t blink and when we remove the signal light the small green led does not blink.
Please HELP! We don’t know what else to do!
Thanks for your help!
