I think I am supposed to install the card and then connect the cable adapter to it. I will not use the Smooth Stepper. I am not sure what the small CD disc is for, it may be for a SATA link driver. Sorry for the confusion on my part.

On another question if I may ask, the ports and pins sheet I got with my X4+ is not very clear on a few points and I hope you may be able to help.
What are output "signals 1 and 2" used for, they are supposed to be connected to pins 3and 9 respectivlly. I am using signal 1 for the coolant.
What is the "A home" input to pin 15 used for? There is no home switch on the 4th axis.
What pins are used for the charge pump?
The last question I have pertains to the problem of spindle speed control. No matter what you set a g code Sxxx you always get the same speed, around 780RPM. The spindle responds to M3,M4 and M5 but not to S requests for different speeds. I know this has been kicked around before but I can not find any resolutions to the problem.
