Hi to all, looks as though I've stumbled at the first hurdle, lets hope this is not a sign of things to come. Anyway I have no native parallel ports on the PC that I intend to use for Mach 3 so have fitted 2 PCI parallel port cards as I will need more than 5 inputs. When I look into device manager they are configured to Port 1 CE00-CE07, IRQ 18 and port 2 CC00-CC07 IRQ 19. So far so good. If I enter CE00 into Port 1 address in config the entry changes to 0x378 however entering CC00 into port 2 address results in 0xcc00. Is this what I should expect?. I want to be able to test the port outputs and the breakout boards prior to connecting to the rest of the control system which I guess I can do through the diagnostics screen, yes? Many thanks for your assistance for what might be a dumb question, it may not be my last methinks.
Bob.
