Pin 1 (+5V out)
Pin 9 (GND )
To use single-ended
encoders, jumper this
pin to GND (pin 9).
Then leave A-, B- and
Z- not connected.
This is not available
on the "MASTER
Encoder" connector.

ENCODER INPUTS:
Differential comparator accepts two-phase quadrature incremental encoders
with differential (recommended) or single-ended outputs. Max. frequency is
12.0 MHz post quadrature. TTL-compatible voltage levels: Low
≤
0.4V,
High
≥
2.4V. Maximum input voltage is 5VDC.
MASTER ENCODER:
The master encoder is used for Following, and not for servo feedback or
stepper stall detect. The pin outs are the same as the other encoders, except
that pin 8 is ISO GND (can’t use a single-ended encoder).
