The Acroloop ACR-8000, if that is what you have, can be run as stand-alone or ISA bus.
If you run on a bus then you need the parallel interface program, if stand alone then the serial.
If you have the board in a slot, then there is not much point in running serial to it.
I also have the AcroCut and AcroMill software that runs on that card.
I am in fact running a couple of Knee mills with it.
What software did you get from Parker?
