24v Power Conector to from the PDB to the cRIO

[mcf747]

Hi everyone,

I have attempted to post on the official first forums but it says that an administrator must approve me so I am going to post her for some one to help me or re-post for me on the FIRST forums.

I know the power adapter linking the cRIO and the Power Distribution Board has 4 "terminals" (please correct me if I am using the wrong terminology) but according to 3.2.6 in the Control System Documentation you only need to use 2 out of the possible 4 connections between the PDB and the cRIO

How do I build a cable for passing 24V power to the cRIO?
1. Take a color coded pair of 22-14AWG wire and cut to length
2. Optionally twist the pair now for better cable management.
3. Strip 5-6mm off of both ends of both wires.
4. Use a small flat head screwdriver to actuate the Sauro CTF04BV8-CN connectors
5. Insert the positive wire in the port labeled “V”
6. Insert the negative wire into the port labeled “C” next to the “V” port.
7. Insert into the Sauro CTM040V8. Tighten screws to ~¼Nm.
8. Give a smart tug to verify the connection is secure.

I was wondering if anyone knows what the other two are for?

Thnanks for any help you can provide,
