Matrox Rapixo CL Pro hardware reference
This chapter provides information on the Matrox Rapixo CL Pro hardware. It
covers the architecture, features, and modes of the board’s acquisition section. In
addition, the chapter covers the Matrox Rapixo CL Pro hardware related to the
formatting and transfer of data. A summary of the features of
Matrox Rapixo CL Pro, as well as pin assignments for the various connectors, can
be found in
Appendix B: Technical information .
Acquisition path
This manual uses the term acquisition path to refer to a path that has the capability
to, for example, capture a component or stream of the video input signal. The
term
independent acquisition path is used to refer to an acquisition path that can,
if required, acquire data from a video source independently from another such
path on the same frame grabber. On Matrox Rapixo CL Pro, there are up to four
acquisition paths (depending on the model).
Digitizer
MIL-Lite uses the concept of a MIL digitizer to represent the acquisition path(s)
with which to grab from one input source of the specified type. When several MIL
digitizers are allocated, their device number along with their DCF identify if they
represent the same path(s) (but perhaps for a different input format) or
independent path(s) for simultaneous acquisition.
Digitizer
configuration format
To program the acquisition section, allocate a MIL digitizer using MdigAlloc()
with an appropriate DCF (supplied or created) and digitizer device number. If
you find a DCF file that is suitable for your video source, but you need to adjust
some of the more common settings, you can do so directly, without adjusting the
file, using the appropriate MIL-Lite function. For more specialized adjustments,
use the Matrox Intellicam program to adjust the DCF file.
