Sync Master Mode
Note:
Sync Master mode can be used for area-scan operations only.
It cannot be used for line-scan operations.
Enabling Sync Master mode automatically disables the Sync
Sentinel. For more information about the Sync Sentinel, refer to
.
Typically, the camera generates the sync signals (composite or
variable-scan) for the DT3152-LS frame grabber board, and the board
locks to them.
If this is not appropriate for your application, you can use Sync
Master mode to set up the DT3152-LS board to generate the sync
signals to drive one or more cameras. The video signal from the
camera is then digitized as usual, using the syncs generated by the
board as the sync basis. This process is called gen-locking.
Gen-locking allows you to synchronize signals when switching
among channels.
You can enable or disable Sync Master mode through software. When
Sync Master mode is enabled, the horizontal sync signal is output on
pin 13 (LINE_CLK) of connector J2; the vertical sync signal is output
on pin 14 (FRAME_CLK) of connector J2. Both are active-low, TTL
signals.
