Stephen,

A pot, or potentiometer, is an electronic component used to change 
the reistance in a circuit to permit volume adjustments. It's often 
found as a rotary control (a volume knob). Jun is pointing out that 
because the inputs on the Yamaha module have no sensitivity control 
of their own, some non-Yamaha pads are going to send signals into 
them like gangbusters and register every hit at too high a level, 
without graduated steps. A pot spliced into the cable leading from 
one of these pads (a Roland, Pintech, or what have you) into a Yamaha 
input would allow the user to adjust the signal strength to keep 
light and intermediate hits from registering too high a gain. The 
Yamaha pads have their own pots to compensate for what the module 
lacks (the TP80S had the sensitivity knob on the bottom), leaving 
other companies' at a disadvantage. The 250k is simply a measurement 
of that resistance, allowing for enough signal attenuation to create 
a smooth curve.
