GPIO in combination with Pulse Width trigger
More precise exposure time can be obtained by using the GPIO in combination with Pulse Width
trigger mode. The clock generator and counter can be programmed in very fine increments. As for
the setting example, refer to chapter 6.5.1.
8.3.4. 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 AC coupled.
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 left).
The internal DIP switch is set to OFF (two switches to the right) as factory default.
