In this scenario, a PIX 240i is the master sync source for multiple cameras , each with or without their
own PIX acting as a recorder. Because of this locked connection, the cameras can be run indefinitely
and be assured of frame-accurate sync with no possibility of drift.
Set the output of the sync generator to a selected rate and connect the PIX 240i Sync Out (Genlock)
and timecode output to multiple cameras (“mult” the genlock output). This connection uses the PIX
240i as both the video sync source and timecode source. Heads and tails sync for the camera’s and
PIX files will be perfect.

In this scenario, each camera is its own master video sync source , but the PIX is the source of the
timecode. The PIX 240i records its files based on the camera’s clock. The heads will match perfectly,
but the tails may drift depending on the cameras’ clocks.
