Norman, Compumotor SX series (SXF) can only be programmed via RS232, you can design "sequences" or program subroutines in SX's memory and activate it with PC's parallel output (using the VRD command that "reads" velocity value from parallel input/output - found in Parker's Command Software Reference guide p/n 88-011871-01E).
In order to work with software like Mach 2 mill, an interface card is needed to send the velocity and direction (using 4 to 8 inputs depending on the design of the sequence) to each drive.
The command VRD uses a 4 digit input.
Interface card can use compumotor's internal 5 DC power supply. Motors can have encoder (recomended) or not. If you use magnetic sensors for displacement limits most of these sensors works with 10 to 30 Vdc.
Have you some SX drives on sale ?
