2.7.5.3 Selectable Auto/Manual Iris
To be able to select between auto and manual iris,
Option C must be installed in the control receiver and
the lens must be modified to use this option. Since
each lens is configured differently, you must consult
with the factory before using this option.
The lens ALC output that normally is connected
internally to the lens iris motor must be disconnected.
Then both the ALC output and the iris motor input must
be brought out to the control receiver board. This
includes both sides of the ALC outputs and the motor
inputs.
