Performing a Passthru Operation
To capture live images and display them (without saving the images),
perform the following steps:
1. If you are using a composite video input signal, connect the video
input signal to channel 0 (VID0_IN). If you are using an S-video
(Y/C) input, connect the Y signal to channel 1 (VID1_IN), and
connect the C signal to the CHROM_IN input.
2. From the DT-Acquire main menu, click Setup , then Select
Device . Leave the remainder of the settings under Setup at their
default values.
3. Select the alias that you gave to the DT3153 board when you
configured the device driver, then click
OK .
4. From the DT-Acquire main menu, click Run , then
Start Pass Thru! .
Live video is asynchronously acquired to display memory, converted to
bitmap format, and displayed on the screen.
5. To stop the asynchronous passthru operation, click Run , then
Stop Pass Thru! from the DT-Acquire main menu.
6. If you wish, modify the parameters available for the DT3153
board by clicking the desired parameter under
Setup and
changing the associated values, then repeat steps 4 and 5.
Note: If you change the video input channel, ensure that you
connect the video input signals to the appropriate channel.
7. When you are finished with this utility, from the DT-Acquire
main menu, click
Setup and Close Device . Then, close the
application.
