PXI 6528 Digital output not working

[NickH.]

Problem: I have a PXI 6528 and I can't get the Digital Outputs to work. 

Background: I've tested all the digital inputs using the +5V and ground on the board and they all work. I can't get the outputs to output any voltage using NI MAX. I've tried hooking the "+" and "-" to a multimeter and I used the test panel to force all the out puts high but that didn't work. I tried "+" and "ground" and I did the same thing forcing all outputs high but no luck. I'm not sure what I am doing wrong unfortunately I'm having trouble understanding the manual for hints on how the digital outputs are suppose to work. I had assumed when sent high they would output a +5V or +3.3V signal. Any help would be appreciated.

Equipment

I have a NI PXI 6528 going into an SCB 100 break out module. I'm using Labview 2014 and NI MAX version 15.0.x.x.

Hello,

Is the SCB 100 in DIO/passthrough mode?

Steps to do this can be found in the SCB-100 Installation Guide:

The SCB 100 is in direct feedthrough mode.

I figured out the the Digital Outputs are just relays and the positive and negative are just 2 sides of a switch.

i am disappointed that the NI PXI 6528 can't supply it's own voltage.

That is correct. 

As this card's outputs are sink/source outputs, they will require an external power supply.

How to connect an external power supply to the PXI-6528 ?
