13.7.4 Encoder Interface

Fig. 13.7 and Fig. 13.8 show, how differential and single ended encoder must be connected to
the GigE camera's I/O interface. Encoder A and B singals must be connected to LineIn0 and
LineIn1. They can be connected in either way, as long as the encoder is configured accordingly
Section C.5.
If available on the encoder, the Z signal must be connected to LineIn2 and the Y/ALARM to
LineIn3.
The EncoderAlarmMode of the encoder configuration must be set to True in order
to use the alarm indication.
Consider the polarity of the encoders Y/ALARM signal. The LineIn3 must be in-
verted, when the Y/ALARM signal is low active.
The Z signal is a single pulse that occurs once every shaft encoder rotation. It can
be used to reset the encoder (Section 6.4).
