I usually make the Brown wire the power (closest to standard black for ground).
On the Digital Sidecar the ground wire for PWMs is to the outside.
On the Jaguar the ground wire goes to the inside (it's marked too).
Even if you got one end wrong, trying the other end in both possible orientations would make it matchup eventually.
Here's a list:
- PWMs opened (only once each) in Begin.vi
- Code downloaded permanently to the robot (Build & Run as startup)
- Driver Station running and in communication with robot
- Robot Code light on DS also green
- Robot Enabled at the Driver Station
- 3 Power lights on Digital Sidecar all bright green
- Digital module in slot 2 of the cRIO
- DB37 cable between the cRIO Digital module and the Sidecar tested for miswiring (forms a loop when plugged into itself, NOT a mobius strip)
- PWM cable ground on Digital sidecar (outside pin) maps to Jaguar ground (inside pin)
- Jaguar powered (the blinking light confirms this)
Try downloading the Default code just while you're working to get the Jaguars communication. Ignore the control changes for now.
