A.5.4
Increment encoder input [X10]
The input supports all commonly available incremental encoders.
For example, Heidenhain encoders conforming to the ROD426 industrial standard, or en-
coders with "Single-Ended" TTL or "Open collector" outputs.
Alternatively, the A and B track signals from the device are interpreted as pulse direction
signals, allowing the controller to be controlled from stepper motor controller cards.

A.5.5
Incremental encoder output [X11]
The output provides incremental encoder signals for processing in higher-level control
systems.
The signals are generated with a freely programmable number of lines from the rotation
angle of the encoder.
In addition to the A and B tracking signals, the emulation also provides a zero impulse,
which goes high for ¼ of a signal period once per rotation (while the A and B tracking
signals are high).
