Solenoid Wiring and Compressor Help

[BurtGummer]

Well, tonight has been an interesting one. The last electrical thing I have to get working is our pneumatic system, and one day to do it, uhhg.

Anyways, I have been trying to get the compressor to run, but I can't get it to do that. The wiring is as follows.

1. Power cables from Distribution board to the Spike, and the other M+ and M- Terminals to the compressor.

2. PWM cable running from spike to the Digital Sidecar Relay channel 1. The Black wire of the cable is closest to the edge/outside of the digital sidecar, and is innermost on the Spike.

3. 2 pin cable, whose connector was cut off and wires stripped to be hooked up to the pressure sensor. The intact 2-pin connector is connected to the middle and outside pins on the Digital Sidecar on the I/O. This is where I think we might be wrong. Do we need to use another 3-pin PWM cable, and run the wiring to the outermost pins on either side of the digital sidecar, not connecting to the middle one?

Simple put, do we connect the pressure sensor wires to the (-) and Signal pins on the digital sidecar, and NOT the PWR pin?

Like I said the above #3 is where I think our problem lies. I'd like to try it, but I'm at home now.

Now, I haven't even tried to conect the solenoid yet. We will be using the Festo one, because it is the only one we have. I know you hookup wires to 1 and 2 on the solenoid, but what pins do they connect to on the actual Pneumatics Bumper on the CRIO? And I assume we need to cut one end of the PWM cable to do the connection on the solenoid right?

This is our first year of doing anything robotics at our school, and we just started 2 weeks ago because of delays. I have already learned soo much from reading these boards!

Thanks!!!!!!
