Thank You Hood,
Hey I have another question, I've been looking over the input cable rework & we determined pins 28,29,30,12&9 should be 0 volts (com-). The wiring diagram I got from seller says 3.5&7 are GND (ground). Here's the question, are ground & 0 vdc (com-) the same thing in this application, I mean can/should I tie these ALL together?

Pins 3, 5 and 7 etc are for the Step/Dir signals and in reality, according to the manual, they should really be the inverse of the signals, ie differential signalling should really be used. Often drives will work fine being connected single ended like that but I always use a line driver to make the step/dir signals differential as it makes them much more immune to noise problems.
Looking at your BOB I am thinking the 24v and the 5v will be tied together internally, you can probably check with an volt meter between the 24v out and gnd and then also between a Dir pin and that Gnd, if you get 24 and 5v (may have to jog a different dir to get the 5v) then they are tied and not much you can do if you use that BOB.
Most drives I have seen have separate commons for the stp/dir inputs and the logic power but whether yours do I dont know, easy enough to check with an ohm meter between the commons of each on the drive itself (with no plug connected)
I wouldnt like to say for sure whether it would be a problem or not if they are isolated but as said if your BOB is not isolated then not much you can do about it.
