RE: [CAD_CAM_EDM_DRO] Re: Indexer LPT

Not so, Art. The dongle only goes on one parallel port, while you
can output signals over up to 3 ports. Even before requiring the
dongle for the windows versions, I-LPT could do 90K PPS, or so.

I've got it and the windows g-code frontend, which I will be using
as soon as I have time to get my hands dirty.

Ballendo:

Ahhh, I think the Hardware assist module is a black box timer.
It is
really what I was curious about. 90,000 PPS from windows seemed an
fantastic
accomplishment and I was very curious about how it was done. I
think the
Dongle is the answer, it is probably like the rutex box, a pulse
timer.

Thanks, your a fountain of information,
