Synchronization
The camera's sensor and SDI outputs can be synchronized to either
a genlock signal (a tri-level HD signal or an analog black burst sig-
nal) present at the BNC SYNC IN connector (1) or a timecode signal
present at the 5-pin LEMO TC connector (2). The camera's sensor
needs to run at equal or double the frame rate of the reference signal
to establish synchronization.
► Select MENU > System > Sensor > Genlock Sync
Following options are available:
Off
Sync In
Timecode
Info: Simultaneous use of the timecode mode Jam-sync and Genlock Sync is not supported.
Sync Shift
The Sync Shift setting can be used to apply an offset to the reference signal at the input. The minimum
step size is 52 ns and the maximum correction is +/- 20 ms (= 384000 steps), depending on the sensor
frame rate.
► Select MENU > System > Sensor > Sync Shift to set the sync shift.
Synchronization is not enabled.
The camera will synchronize to a tri-level or black burst signal present at the SYNC IN connector.
The camera will synchronize to timecode present at the TC connector.
Active synchronization is indicated by the Genlock icon on the HOME screen and in the
Status Info. The icon turns orange when the camera cannot synchronize to the reference
signal or when no signal is present. See MENU > Alerts for detailed information.
