Pass Thru
When you select Sync Out Pass Thru, the
signal received on Sync In is sent to Sync
Out. The only setting t ha t a ff ects this
signal is the Invert Sync In option which
simply inverts the signal.
5-3 Master/Slave Setup
There are many possible configu r ations
used to synchronize groups of cameras.
The Master/Slave configu r ation is o ft en used when a group cameras is used to capture multipl
synchronous views of an event that is not driven by a clock or PLC. For example, when studying
animal or human kinetics, th e subject (animal or human) is not supplying a sync signal for the
camera system, so the camera system uses its own: Sync Out from a Master camera.
In this configu
r ation any camera may be used as the Master.
Commonly, all cameras are set to the same Frame Rate and Resolution are triggered together,
and integrate frames together (synchronize frame start tim e s). For this setup:
• Enable External Trigger for all cameras and use the same polarity for all.
• Sync Out from the Master camera is set to “Per Frame”
• Sync Out for the Slave cameras are set to “Pass Thru.” Invert Sync In is
not selected.
• Sync In for the Slave cameras Master Frame rate is set the same as the Frame rate of the Master
camera.
• Choice of Shu tt er or Duty Cycle does not ma tt er.
