Table 13.8: Available input standards of LineIn0, LineIn1 and LineIn2 (Footnotes:
1)
The HTL treshold con-
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
Ω
resistor and
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.
