SDI Input Embedded Timecode
The PIX 240i can use timecode embedded in the SDI or HDMI input signal.
Timecode/Sync
 Timecode Mode must be set to Ext TC (SDI, HDMI).
HDMI Input Embedded Timecode
The PIX recorders can use timecode embedded in the HDMI input signal.
Timecode/Sync
 Timecode Mode must be set to Ext TC (SDI, HDMI) on the PIX 240i or
Ext TC (HDMI) on the PIX 220i.
Synchronization/Timecode Examples
The following examples illustrate common scenarios where synchronization can be employed with
the PIX 240i and other devices.

In this scenario, the video camera is the master source of the video sync. The timecode can either be
read from the camera or be generated by the PIX 240i. The accuracy of the recording is dependent on
the internal clock accuracy of the camera.
To receive timecode from the camera, set Timecode/Sync  Timecode Mode to Ext TC (LTC) for cam-
eras that output standard SMPTE timecode to the PIX 240i’s Timecode BNC or LEMO 5-pin input.
Alternatively, the PIX 240i can receive timecode from the SDI or HDMI input (if the camera sends
timecode in this way) by setting Timecode/Sync
 Timecode Mode to Ext TC (SDI, HDMI).
The Setup Menu option Timecode/Sync  Sync Out can be set to several valid settings, including the
following:
• Off - sync signal is disabled.
• Genlock, Follows Video In - Genlock for another camera is derived from the video signal of the
single camera.
• Wordclock, Follows Video In - Wordclock for an audio device is derived from the video signal
of the single camera.

In this scenario, the PIX 240i is the master source of video sync. Set the output of the sync generator
to a selected rate and connect the PIX 240i Sync Out (Genlock) to the same camera. Feed the time-
code output of the PIX 240i into the timecode input of the camera.
