Parallel Port breakout boards, motherboards, and dedicated accessories / pmdx-126 and limit switches

I am in the process of replacing a gecko-g540 with a pmdx-126.
The swap has been pretty straight forward with the exception of limit switches.
The limit switches are 2-wire npn proximity switches that run off 12-24 vdc.
The g540 was able to drive a pair on Omron tl-n7dm2 wired in series on a single input and a pair of q5md2 on another input .
How would I go about hooking this up to the pmdx-126? If they are wired like mechanical switches and say use jp11 pin 11/gnd is used there isn't enough power to activate them.
