Digital Side Car issues

[Jon Stratis]

Possible problems in order of likelihood:
1. Incorrectly assembled/damaged cable
2. Poorly written code (This is always high on the list... it would be number 1, except you got ports 1-4 working, so it seems like you should know what you're doing for the other ports)
3. Damage to the DSC (metal shavings, burned out components)
4. Damage to the Digital I/O module on the cRio (a bent/broken pin, burned out through misuse)
5. Damage to the cRio (a bent/broken pin, metal shavings, burned out components)

Start by replacing the cable. If that doesn't work, replace the side car. If that still doesn't work, pray that someone has a space cRio you can try out.
