Manta Technical Manual V8.0.1
Test conditions
Output: external 2.4 kΩ resistor to GND, isolated out power set to 12 V.
Auto Iris (video type) output description
Manta cameras provide built-in video type auto iris controls.
Higher external values increase the times in the previous table.
NOTICE
The following schematic uses Camera POWER to power the video iris lens and
assumes Camera POWER = 12 V. Most video iris lenses operate at an 8 to 16 V
input voltage. Therefore, this circuit is not appropriate when using a 24 V camera
power supply. Doing so may irreparably damage your lens. Consult your video type
auto iris lens specifications for the appropriate drive voltage.
