LPTx in PC vs Port#1 in Mach3 ??? just need to clarify
« on: May 03, 2010, 04:52:58 PM »
My computer has no parallel port on motherboard, so I bought a PCI parallel port board, and I set it as LPT2 in PC. While in Mach3, I clicked the port#1 and input the related LPT2 address. It works, anyway.

Does it really matter if I set PCI as LPT1 or LPT3 or LPTx as long as I set port#1 with correct address?

I tested with setting as LPT1 in PC, it works too. why?

Thanks.

As you have found the Port in Mach has no relation to the LPT number that windows calls it, Mach just looks at the address you enter.

Look at the resources of the port in Device Manager.
