You would need a new firmware for the Any-IO card, as I think that the
7i89 is almost entirely passive.

(It does have firmware, but I don't know what it does)

Looking at the pinout of the DB25 each encoder channel appears there,
so the actual counting is on the FPGA card that the 7i89 plugs into.

Why do you need 24 frequency counters? This sounds like you might be
doing analogue input via voltage to frequency conversion? In that case
there are likely to be better choices.
