Have a look at DB25 breakout boards. Generally they give you one or two (male/female) DB25 ports wired to a barrier strip with screw terminals.
Using those you just mount a breakout board in proximity to the Ipac, run wires between the screw terminals on each pcb, and run a stock DB25 cable to your control panel. Another breakout board of the same kind can offer termination at the control panel end, no cutting, soldering or hacking required.
