following steps:

input signal to channel 0 (VID0). If you are using an S-video
(Y/C) input, connect the Y signal to the luminance signal of
channel 1 (Y1), and connect the C signal to the chrominance
signal of channel 1 (C1).
2. From the DT-Acquire main menu, click Setup , then click Select
Device .
3. Select the alias that you gave to the DT3130 Series board when
you configured the device driver, then click
OK . To get started,
select device -1.
4. Leave the remainder of the settings under Setup at their default
values.
5. From the DT-Acquire main menu, click Run , then Single Frame

changing the associated values, then repeat step 5.
Note: If you change the video input channel, ensure that you
connect the video input signals to the appropriate channel.
