GENLOCK
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
NOTE: Genlock is ONLY possible between BRAINs that can achieve the same project time base and sensor 
frame rate.
MONITOR SYNC
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 BRAIN is using another form of synchronization to sync the 
camera sensor. 
1.  Connect the desired genlock device to the BRAIN using a 3BNC-to-00 LEMO Sync Cable.
A.  Connect the green BNC connector to the genlock device.
B.  Connect the 00B LEMO connector to the SYNC port on the BRAIN.
2.  Go to Menu > Settings > Display > Monitor Control.
3.  On the Monitor tab, select Brain 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.
