Key Features
Key features of the DT3145 frame grabber board are summarized as
follows:
• Operates on the 32-bit, 33 MHz PCI local bus interface.
• Accepts a single Camera Link-compatible digital source
operating in area-scan or line-scan mode.
• Acquires and stores data in single-port format (8-bit, 10-bit,
12-bit, 14-bit, and 16-bit monochrome), dual-port format (8-bit,
10-bit, and 12-bit monochrome), or RGB format (24-bit color).
• In area-scan mode, acquires regions of interest (ROIs), also called
areas of interest or AOIs, that are 8 to 4,096 pixels wide by 1 to
4,096 lines high, depending on your camera.
• In line-scan mode, acquires lines that contain 8 to 16,384 pixels,
depending on your camera. You can acquire either a single line
or multiple lines to build your own frame.
• Acquires data at frequencies up to 66 MHz, determined by the
Camera Link clock.
• Accepts an external trigger (either isolated or TTL) with
software-selectable polarity.
• Provides two programmable look-up-tables (LUTs), each with
three 256 x 8-bit sections that correspond to input ports
A, B, and C.
• Provides four, software-selectable camera control output signals,
which you can program to output the following:
−
An expose output signal to control the exposure time for
asynchronous reset cameras.
−
An integration signal to control the exposure time for
line-scan cameras.
−
A strobe output signal to control lighting.
−
A general-purpose output signal.
