This chapter provides information on the Zebra Rapixo CoF hardware. It covers the architecture, features, and modes of the board’s acquisition section. In addition, the chapter covers the Zebra Rapixo CoF hardware related to the formatting and transfer of data. A summary of the features of Zebra Rapixo CoF, as well as pin assignments for the various connectors, can be found in Chapter 5: 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 Zebra Rapixo CoF, each CoaXPress connection in a CoaXPress link uses the same acquisition path.
Digitizer.
Aurora Imaging Library-Lite uses the concept of an Aurora Imaging Library digitizer to represent the acquisition path(s) with which to grab from one input source (one CoaXPress link on Zebra Rapixo CoF) of the specified type. When several Aurora Imaging Library 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 an Aurora Imaging Library 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 Aurora Imaging Library-Lite function. For more specialized adjustments, use the Zebra Imaging Capture Works program to adjust the DCF file.
