Does windows see it now? If so then as long as it is a proper parallel port then it should work with Mach.

Forgive the flood of screenshots, but I'm hoping you can confirm that I am seeing a corectly installed port.  I am thinking that it is?

I'm at a loss.  If it is installed right, then perhaps I need to start considering the purchase of a regular 5v 32bit PCI parallel card?

Thanks Hood,

So that leads me back to the question of why my inputs for M1-- and M1home are not displaying an LED when they are configured just like the other input pins.  Nothing is hooked up to the parallel port.  So it can't be external.  I have the pins all set to active high which should indicate a triggered switch since nothing is hooked up.  Pins 12, 13, 15, and 10 do this, but pin 11 doesn't.  

I guess that is why I am second guessing the parallel port card (pci express).

At this point, I am kind of dead in the water.

It seems to me that for some reason your card is still not being seen properly. Try shorting the pins to Gnd on the ones that do work and see if the state changes, also do the same for the ones that are not working. If neither change then Mach is looking at the wrong port for some reason.

What does this mean? (pin 11 being inverted that is?)  Does that mean that in order to run active high, I have to be checked active low?

It would make sense in respect to what I am seeing.....

Or, is this even the type of parallel I'm using?

YOU do realize that not all pins on the port are bidirectional. Some are inPut only some are output only on Machs port useage..
(;-)

ONly on Mach port 2 can you set it up to be all input

Thanks for the input Vmax!  Yeah, the pins I'm using for input are 10, 11, 12, 13, 15.   My question is whether or not that single inverted pin on inputs (11) is causing me to have to set it as active low in order to make the led light up on the diagnostic tab.  I have nothing hooked up to the parallel.  So nothing should be able to recieve the 5v signal, right?  Or am I wrong??  I'm not totally sure.  My  table is wired to have the limits and homes all normally closed.  So I would want active high, right? ???

I just got home and I am going to try what hood said.

Thanks

One queston:

Are any of the pins 18-25 a suitable ground pin for any of pins 10, 11, 12, 13, and 15?

Sorry for the bombardment of questions?

Thanks,
