Unplug the ribbon cable from the sidecar, and see if all three power lights on the sidecar are lit up.

Which slot is your NI 9742 module installed in?

To help rule out hardware problems with the cRIO or the module, run one of the examples (e.g. Solenoid with Compressor). If the green LED on the module still doesn't light when you turn on the solenoid output, I suggest that you should talk to NI about getting a replacement.

That's good advice for problems controlling a Spike relay, but the Digital Sidecar is not involved at all in the problem being described here.

Thanks, we will try this on Monday.

Totally missed the 24v solenoid part... Thanks.
