I used the original THCAD card on my parallel port. You have to set the
output frequency divider so the software can read the pulse stream.

It also says "The frequency output can optionally be divided by 32, 64

I think I answered my own question. Per the documentation output of the
THCAD is 100Khz to 1Mhz. Looks like it needs an FPGA encoder counter.

Will the THCAD work with the paralell port? Will he need an FPGA card in
order to use the THCAD card?

I use the Mesa THCAD card to convert volts to frequency then the thc
component to control my Z while cutting. About 1/5th the cost of that.
But if your using a Ox/Acc torch then you need that. For plasma you want
to control the height based on tip voltage.

The controller that he already has is Modbus, but I am not sure how
well that integrates with Realtime/HAL

New on 2.4 is a THC comp designed to work with the Mesa THCAD High
Isolation A-D Card. This card takes a 0-10v input and converts it to a
pulse that is read by the 5i20 encoder input. The velocity output goes
into my THC comp and controls the Z axis with offsets to maintain the
desired input. A

John,
Yes, that is controlled via the 'anti-dive' settings.

They have both a cabinet and rack mount unit.
