7.5.5 Auto Iris Lens video output (12-pin Hirose connector)
This analog 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.
Fig. 25 Video output circuit.
To use this signal, an 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
