I have an H-100 Controll on a Hitachi 345Q machine. I have the Stop bits at 1 on my Mastercam, Paraty at none, and data bits at 8. I can change these in mastercam, but am not sure how or what parameters to change on the EDM Control. Baud Rate is at 9600. I can send from the machine to the computer but not the other way around. Any Ideas?
