7.7. 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 mode only.
The signal is taken after the CCD sensor output passes through the gain circuit. The video
output is without sync. The signal is 0.7 Vp-p.
To get this signal, the internal DIP switch (SW 601) must be set. Refer chapter 5.4.
