http://pico-systems.com/codes/jebport/ contains the complete configs file set for my Bridgeport. This uses my PPMC servo interface hardware. The most significant file is pendant.hal, which has all the code for the pendant. The jog encoder is read in on channel 3 of the PPMC encoder counter board. http://pico-systems.com/codes/minimill/ contains the complete configs for my minimill. This uses my Universal PWM Controller board, but all channels are in use here. (The 4th encoder counter is used for the spindle, the 4th PWM output is used to run the spindle motor.) So, I had to use general digital I/O for the jog encoder. Both of these configs use the ilowpass filter to remove the high-frequency steps from the jog encoder so the servos don't go crazy when you move the dial. Oh, one comment on the CNC4PC pendant. There is an unlabeled white button on it. It is wired normally closed, and in series with the axis selector switch. This made no sense to me, if you press the button it can't read the switch position. So, I moved a wire to the normally OPEN contact, so you had to push the button to enable the axis selector. If you don't press the button, it doeasn't jog, so you can't accidentally bump the dial and crash the machine. I have wired my two machines the same way.
