How would I set them up so they both run on one computer. They run on serial cables. Thanks Dave Chris Wool replied 13 years, 5 months ago 1 Member · 1 Reply 1 Reply Chris Wool Member 22 June 2012 at 17:12 think the older summas have a paralel (printer port) as well so could use that for one of them. or usb if it has it. or add a serial port card to the computer or use a usb to serial converter or use a switching box either one or the other.
