Table 14.8: Available input standards of LineIn0, LineIn1 and LineIn2 (Footnotes:
figuration is set globally to all inputs, which are configured as single ended HTL.)
Differential P and N input is available on the 17-pin I/O connector, when a dif-
ferential input standard is selected.
If a single ended I/O standard is configured, only the P input is available. The N
input must be tied to ISO_GND externally.
The input standard of LineIn3 is TTL and terminated with a 120
can't be changed. This line can be used either as a normal camera line input or
as an encoder alarm indication. If used as an encoder alarm indication it must be
activated by setting the EncoderAlarmMode to True. Otherwise this configuration
must be set to False.
The isolated RS485 input on the 17-pin I/O connector is optional. Please contact
Photonfocus for activation.
