I will check what Jon's PPMC does, but I think that he takes 5v
differential signals.

The PPMC has jumpers to set each encoder for differential or
single-ended, and provides up to 200 mA at 5 V to each encoder with a
self-resetting thermal "fuse" (PolySwitch). It also has a termination
resistor (120 Ohms) when in differential mode to absorb reflections on
the lines.
