5.5.5 Resolver and Incremental (TTL) Encoder
This example of a resolver on A and B as channel 1 and a 2-track incremental TTL encoder on Z and D as channel 2. The internal
supply of the option is used for resolver excitation. The encoder supply (pin 17) is inactive, so the incremental encoder must be
supplied by an external power source.
