(I thought I had a schematic of the pendant wiring for the PPMC, but it is very similar to the way the minimill pendant is set up. I'll try to get that drawing on there shortly.) These use diodes to encode the switch settings, so you can hook up 7 axis selections (XYZAB plus feedrate and spindle override) and 3 jog rate selections with only 5 digital inputs.
