put finger to keyboard and composed:

The above encoders are optical types, so you will need to wire up a 5V
DC supply.

I notice that there are three unused wires in the J12/J13 harness in
the Model 23. If the Model 75 also has unused conductors, then maybe
you could utilise them for bussing the +5V supply to the optical
encoder.
