Looking for assistance in connecting COMPUMOTOR DB DRIVE

I have 2 COMPUMOTOR DB DRIVE units which I would like to make use of.

I am trying to identify the functions of the wires that connect to these
units.

I would appreciate any feedback or links to web site as you may have.....

Also, any comments from anyone who has actually used these drives woudl be
welcome.

Pinouts for COMPUMOTOR DB DRIVE

On the LEFT side of the controller is an 8 position screw terminal which
looks like the power and motor side. It is labelled as follows:

B+ To Motor
B - To Motor
A + To Motor
A - To Motor

- 12-48V DC IN
+ 12-48V DC IN

CURRENT (No idea what this is for. Is this also tied to the DC
Supply voltage?
LOGIC GROUND (Do I just tie this to the PC Controller Ground and/or
to chassis ground?)



On the RIGHT side of the controller is an 8 Position screw terminal which
looks like the controller side. It is labelled as follows:

LOGIC GROUND (Do I just tie this to the PC Controller Ground and/or
to chassis ground?)

RES SEL A (No idea what this is but "A" is jumpered to "B" and
"C" Is not connected)
RES SEL B (No idea what this is but "A" is jumpered to "B" and
"C" Is not connected)
RES SEL C (No idea what this is but "A" is jumpered to "B" and
"C" Is not connected)

DIR - (I assume that this goes to the direction pin on
the controller?)
DIR + (I assume that this goes to the direction pin on
the controller?)

STEP - (I assume that this goes to the step pin on the
controller?)
