Synchronizing to an external source is most common in applications whe r e a preferred sync pulse
is available such as one from a PLC, IRIG, or GPS.
NOTE: Please refer to “Appendix D: Power and I/O Connections” on pa
e 82, for
electrical specifi c ations .
This sync pulse may be used for a localized group of cameras, in which the cameras are connected as
in “Figure 5-6: External Sync: Local Grouping” on page 40 is commonly used. The cameras may also
be placed far apart, in which case they are connected to a distributed sync signal as in “Figure 5-7:
External Sync: Distributed Grouping”.
In the case of using a PLC or other local clock, you will need to know the polarity and frequency of
the signal in order to set the cameras up. Optimum f r ame rates can o ft en be derived using the
Rate Devisor function
When using IRIG or GPS as an input, you will fi
r st need to derive a 1Hz signal from the source,
then use the Per Second option. This gi v es you complete fl e xibility with respect to frame rate: you
can select any frame rate you wish to use.
Note: full IRIG and GPS implementation is planned
f or a future release.
Triggering in a distributed grouping may either be implemented locally via switch, camera bu tt on,
or soft w are, or it may be available along with the sync as a distributed signal.
