SYNC MENU
This menu is used to select the way the camera maintains frame synchronisation. The
menu changes depending on the sync mode selected.
Options: AUTO, INT
When AUTO is selected the camera will automatically set itself for the appropriate sync/
power input. To do this, the camera checks for a genlock synchronisation signal. If a genlock
signal has been applied to the camera, then the camera will lock its frame rate to that of the
genlock source. A genlock synchronisation signal can be used with AC and DC power
supplies.
If a genlock synchronisation signal is not present, the camera will then check for an AC
power source. If an AC power source is present, the camera will line lock its frame rate to
the AC frequency, ensuring that the camera is triggered at the same point on every AC
cycle.
Only if neither of these sources are present will the camera default to the INT option (internal
lock). The INT option locks the camera frame rate to a frequency generated by an internal
crystal.
If required, the INT option can also be selected in the menu regardless of whether a
genlock synchronisation signal or an AC power source is present.
When AUTO is selected, a number of options will be displayed in the menu (as seen
above). However, H PHASE, SC PHASE and GENLOCK TERM are only applicable when
a genlock source is being used for synchronisation. Adjusting these settings will have no
effect if the camera is using an linelocked AC power supply for synchronisation.
The V PHASE menu item can be used both when a genlock source is being used for
synchronisation and when an AC power supply is being used. However its reference changes
in each instance.
See the following page for more details on these menu items.
