Section III: Timings specifications
When you have, for example, an camera with incomplete documentation, or there
is no DCF available which matches the camera closely, and the camera cannot be
sent into Matrox Imaging for testing, fill in the information requested below, or
include the timing specification documentation provided by your camera
manufacturer. Refer to the manual for your particular frame grabber for possible
grab limitations.
