The nodes listed under the device name are the formats the device supports. They
may correspond to the different resolutions and color spaces that your device
supports, or to different video standards or camera configurations. This information
comes from your device adaptor. Select the format you want to use.
See “Selecting Your Device in Image Acquisition Tool” on page 3-8 for more
information about devices and formats.

Use the Preview feature to test and set up your device by clicking the Start
Preview button. If necessary, physically adjust the device to achieve the desired
image area, or use the Region of Interest tab of the Acquisition Parameters
pane to constrain the image.
See “Previewing Data” on page 3-30 for more information on previewing.
3
Set the Frames Per Trigger on the General tab and the Number of Triggers on
the Triggering tab, to set the total number of frames for the acquisition, if you did
not do so while previewing.
For example, if you set Frames Per Trigger to 4 and Number of Triggers to 2,
the total number of frames acquired will be 8.
If you just want a snapshot of one frame, leave the default settings of 1 in both fields.
If you want a specific number of frames, use the fields to set it.
Alternatively, you can set the tool to acquire continuously and use the buttons in the
Preview window to manually start and stop the acquisition.

Set any necessary acquisition parameters if you did not do so while previewing. See
“Setting Acquisition Parameters in Image Acquisition Tool” on page 3-11 for more
information.
5
Choose your log mode, which determines where the acquisition data is stored.
On the Logging tab, use the Log To field to choose to log to memory, disk, or both.
Disk logging results in a saved VideoWriter file. If you choose memory logging, you
can export your data after the acquisition using the Export Data button on the
Preview window.
For more information about logging, see “Logging Your Data” on page 3-16.

Start the acquisition by clicking the Start Acquisition button.
