Operating Mode settings include:
•
Slave Acquisition Mode—The 1408 device supports the following
slave acquisition modes:
–
Standard—In standard mode, the 1408 device receives an
incoming video signal and generates a CSYNC signal. The
internal CSYNC signal generates the PCLK, HSYNC, and
VSYNC signals. The 1408 device acquisition control circuitry
uses these signals to store the acquired data in PCI memory.
You can control each of these signals in software. The board
parameters adjust the pixels per line (to generate PCLK), the
horizontal start (to generate HSYNC), and the vertical start and
lines (to generate VSYNC).
Note:
The Signal Polarity, CSYNC Source, and PCLK Select options are
disabled in this mode.
