GENLOCK
NOTE: Using genlock requires a DSMC2 Base Expander, DSMC2 V-Lock I/O Expander, DSMC2 Jetpack
Expander, DSMC2 Jetpack-SDI Expander, or DSMC2 REDVOLT Expander. For more information, go to “Input/
Output Connectors” on page 167.
Generator locking (genlock) is a tri-level signal used to synchronize video and audio systems. Genlock is based
on SMPTE 296M and 274M.
There are two (2) important genlock sync modes:
Monitor Sync
Sensor Sync
MONITOR SYNC
NOTE: Using genlock requires a DSMC2 Base Expander, DSMC2 V-Lock I/O Expander, DSMC2 Jetpack
Expander, DSMC2 Jetpack-SDI Expander, or DSMC2 REDVOLT Expander. For more information, go to “Input/
Output Connectors” on page 167.
Monitor Sync occurs when a genlock signal is provided that is compatible with the current monitor output
frequency. Monitor Sync is achievable even if the camera is using another form of synchronization to sync the
camera sensor.
1. Connect the genlock device to the camera:
‒ DSMC2 Base Expander, DSMC2 V-Lock I/O Expander, DSMC2 Jetpack Expander, or DSMC2 Jetpack-SDI Ex-
pander: Connect the SYNC port (00B) on the expander to the device (green BNC) using a 3BNC-to-00
LEMO Sync Cable.
‒ DSMC2 REDVOLT Expander: Connect the GENLOCK port on the expander to the device using a 75 ohm
BNC cable.
2. Go to Menu > Settings > Display > Monitor Control > Monitor.
3. Select HDSDI from the drop-down menu.
4. Select the desired monitor output frequency from the Frequency drop-down menu.
NOTE: Select Auto to automatically match the HD-SDI output to the current Project Time Base.
Monitor Sync is achieved automatically when a genlock signal is provided that is compatible with the
current monitor output frequency. When Monitor Sync is achieved, the GEN indicator in the Lower Status
Row illuminates green.
