Consolidating PWM's to one serial cable

Still, this would get you 8PWM sigals and one ground per cable for the Victor drives. Very interesting....

Did you also consider using CAT5 (Ethernet) cable? The RJ series connectors are quicker to disconnect/connect and are just as secure as the DB9 cables... but its pretty much a draw for which is better.

It'll be interesting to see how this turns out....

The CAT5 does sound like an interesting solution. Only problem i see with that is that the CAT5 wire to my memory ( i could be wrong) only has 8 pins. So that would make for a weird distribution of wiring.
Unless I put 4 victors per CAT5 wire (if i remove the ground) and then have a CAT5 wire just for grounding purposes, which may workout that I can still give each victor its own ground.
Thank you for the idea. Sorry i was kinda thinking out loud there.
