Sync Signals

Variable-Scan Video Signals
If you want to use variable-scan video signals, the camera or
imaging/device must provide the horizontal and vertical sync
signals. Pin 1 of connector J1 on the DT3162 accepts a vertical sync
signal; pin 2 of connector J1 on the DT3162 accepts a horizontal sync
signal. Both the EP332 cable and the CAMERA connector on the
Camera Interface Module accept horizontal and vertical sync input
signals.
Note:
Pins 1 and 2 of connector J1 on the DT3162 accept sync input
signals only if sync output mode, described in the following section,
is disabled.
If you are using a variable-scan video signal, specify the sync input
source as ExternalSync using software. You can also specify the
polarity of the horizontal and vertical sync signals (ActiveHigh or
ActiveLow). Selecting an active-high polarity means that the sync
input pulse is a low-to-high going signal; selecting an active-low
polarity means that the sync input pulse is a high-to-low going
signal.
