Sync Sources

Previzion’s internal data capture and rendering engine can be synchronized to external, data driven signals, or an internal timer when no external sync data signal is available. The external encoder box and the Airtrack both generate serial data streams when triggered by a tri-level sync genlock signal applied to their genlock input.

When first started up, Previzion defaults to the Timer sync, but will store the selected sync sources when shut down, and automatically reconnect to them when started up again.

Configure Timer Frame Rate

Clicking Config to the right of the Timer sync source opens the dialog box above. This is only done for test purposes; in actual use it is necessary to use a genlocked data source such as the Airtrack or the encoder system to provide sync.

Airtrack Sync

When the Airtrack or encoder box is connected to Previzion over RS232 and connected to a genlock signal, the green light to the right of the drop down box will light up to show a sync connection.

Select Airtrack from the Sync menu, and verify that the green light goes on. If not, check the power and serial data connections for the Airtrack.
