DT3120 Device Driver Capabilities

30
Because the Frame Grabber SDK is intended to be used with all
DT-Open Layers frame grabbers, the DT3120 may not support all of
the Frame Grabber SDK capabilities or may support the Frame
Grabber SDK capabilities differently from other boards.
To help you determine which capabilities are supported by the
DT3120 board, you can use query functions provided by the Frame
Grabber SDK. These functions return either information about a
specific capability or the current value of a specific capability.
The tables in this chapter list the capabilities supported by the
DT3120 board and the information needed to query the board. The
left column of the tables lists the capabilities along with the query
key/control used for the listed function. The query's possible
returned flags, if any, are indented under the key along with a
description. The right column indicates whether the DT3120 board
support the capability or flag or the range of values supported by the
capability.
To find the information about a capability more readily, use this
information:
