Camera identification and control
6.
In this chapter, the functionality of the camera is explained by means of the commands that control it.
The subsections are in fact the ICategories (see section 5.2.2).
Interface settings (ICategory: BootstrapCoaXPress)
6.1
The Bootstrap CoaXPress consists of a set of identification parameters as well as parameters to
configure interface settings.
Interface and xml file identification
6.1.1.
The parameters in the table below are reserved for identification of the interface.
The Standard is identified by the number 3232209637. In Hex this equals C0A79AE5, which looks
similar to the word ‘COAXPRESS’; the CXP revision 65536 corresponds to 10000 in Hex and equals
revision 1.0 of the standard.

Interface configuration
6.1.2.
The Q-xAxxx/CXP described in this manual can be operated with a single or a double link, with the link
bit rate configurable by LinkConfig. Note that the camera always starts up in LinkConfigDefault.
The LinkConfig value looks like LinkXSpeedYYYY, where X is the number of links (1 or 2) and YYYY is
the data rate per link in Mb/s (1250, 2500, 3125, 5000 or 6250).
The camera has a buffered pipeline architecture, in which the sensor with it’s acquisition frame rate
and the interface with it’s transmission frame rate are decoupled. The minimum of the two determines
the highest possible sustained frame rate. In section 6.4 this is explained in more detail. Also, there
more information is provided on how the interface speed depends on it’s exact configuration.
