I just had a Apollo brain open a few weeks ago, but AFAIK scrollerpower supplies are very similar.
There is a power supply, (or 2) that put power down pins 1 and 4. And DMX sent down pins 2 and 3. I would think this is something simple, like a loose optoisolator chip.
I would move it around a lot as you have it on the bench.
Also, when you say it won't send data or pass it through, do you mean it won't pass DMX? That seems unlikely. But if nothing else it should help you troubleshoot. DMX ports are a straight passthrough.

I may be a little late to the party, but I think you have a ground issue. If the power supply works on the bench, then it should work in the air if you isolate it from the rig. As to schematics, they will be available starting July 1 on the website.
