Help connecting a stepper driver

Hi Guys

Im in dire straights at the moment.
System consists of Sound logic BOB ,Rutex servo drives and some Reliance Electric servos. Every thing works great.

Problem...... Now I am trying to connect a chinese stepper + driver for a 4th axis.

When I conect with the chinese BOB all is well. Stepper works as it should.

When I try to conect withe current Souind Logic BOB I can not get it to work.

See Atached pic for chinese bob connection.

Markings on chinese driver is as follow:
CP+
CP-
CW+
CW-
EN+
EN-

Markings on Sound Logic BOB:
Dir
Step
+5V

I tried the following connctions:
CP+ ------+5V
CP- ------ Step
CW- ----- Dir

No movement with the above connection.
When I remove the +5V and bridge CP+ CW+ EN+ (as with chinese BOB)I get movement only in one direction. Changing the step high lo setting nothing happens. Changing the Dir High Lo setting movement is still the same but buttons on the Mach changes from A+ to A-

Urgently in need of help please.

Thanks
Deon
