1) Compressor is normally powered by a spike, since it is just I/O
2) The solenoid comes off the solenoid breakout. The breakout is powered either to 24 or 12 volts, depending on which solenoid you have (it should be labeled). So, PDB to solenoid breakout on the cRIO, and from the 8 inputs on there, you put one or two two wire signal cables. Dual action solenoid gets 2, single action gets 1
3) Solenoids can be powered from a spike, but I myself have never tried this, so someone will have to walk you through it.
4) If you are using a robot, you need a cRIO. however, if you use a spike, you will wire it to the digital sidecar, whereas my way you wire to the solenoid breakout board on module 9472. If you use a spike, this module is unnecessary. However, you still need the cRIO for at least the module that connects to the digital sidecar (9403). Either way, you still need a cRIO
5)On the solenoid breakout board, you need the top attachment (the Solenoid breakout itself mounted on the 9472 module. And on the board, you ned to have the signal wirees to the solenoid (one on each side, or just one for signle action)
