Re: [CAD_CAM_EDM_DRO] Compumotor OEM 670X drives

Jon:
Yes it is a RS232C interface it uses only a 3
wire connection pin 2,3,5 on a 9 pin and 2,3,7 on a 25
pin. It uses X lanuage for communication.Loop back
shows a good echo from the computer but none of the 5
OEM controllers will respond.

Thank you for repling. Mike Guyer
