power bar wiring question
#1
Hi,
I'm a little confused on the power bar wiring (the first power bar, with the 12 v power supply in it.  So I connect the wires to the vga connector, 1-8 signals and black to ground pin.  The other ends of these wires connect to the corresponding relay board pins.  I don't connect the white wire to the VGA connector (power), instead I connect the white wire to the 5v + side of the regulator.  The regulator gets 12v power and ground from the power supply (in parallel with the dc jack that goes to the controller).  Where do I hook the ground to on the 5v side of the regulator?  My thought was wiring it to the extra ground point on the relay board.  Is that ok?  Did I miss anything?  I looked at the diagram and description in the instructions, but it didn't make complete sense to me.

Thanks,
Warren

Further to this, I did some testing.  First, the 5 volt regulator seems to put out closer to 8.7v on the 5 v side, which seems pretty high.  My outlets are on by default, with 3.3v on the pins and while I see the voltage drop when I toggle the pins via the touchscreen, the voltage drops to .45 v, but the relay never switches, it just stays on.  The indicator LEDs in the power bar dim when I toggle, but don't turn off completely.

Ideas? 
Thanks,
Warren
