Flare 12M CXP User's Manual
3.12 Lens Control
The 12M180 cameras come with support for an optional EF lens mount with integrated lens
control. The EF lens mount is connected with a FLARE-EF adapter, shown in Figure 16, and
its associated cable, CABFLAREBATT2.
Note
: The EF lens adapter requires a 12V power
supplied by the CABFLAREBATT2 cable connected to the main camera power connector. It
is likely the camera will use the 12V supply to power up because of the delay in the power
sequencing using PoCXP in the frame grabber. When using the EF adapter it is
recommended to disable PoCXP on the frame grabber to avoid any camera detection issues
3.12.1 Aperture
The lens aperture is controlled through the
Len Control Aperture
register. A value of 0x00
corresponds to the lens' largest aperture (smallest F-number). The Maximum Lens Aperture
register reports the lens' maximum aperture value, corresponding to its smallest aperture
(largest F-number).
