7.5.5 Auto Iris Lens video output (12-pin Hirose connector)

This analogue signal is not routed through the GPIO.
This signal is available at pin 4 of 12-pin Hirose connector. It
can be used for lens iris control in Continuous and RCT modes
only.
The signal is taken from the CCD sensor and is output after the
gain circuit. The video output is without sync. The signal is 0.7
V p-p from <400 Ω AC coupled.
To get this signal, the internal DIP switch must be set
as follows.
The auto-iris lens video output is enabled by setting switch
SW600 to ON (two switches to the left). The internal DIP
switch is set to OFF (two switches to the right) as factory default.
