Iris control voltage (V)
IRIS
7-2-2. IRIS control input
When terminal D is open, the VCR becomes AUTO-IRIS mode. When terminal D connects with the GND, the VCR
becomes MANUAL-IRIS mode.
With the voltage to input to the C terminal, the iris is changes. As for the relation between the iris control voltage
and the iris, it is as shown in the following.
Even if AUTO-IRIS is used, the iris can be corrected according to the input voltage.

NOTE:
The control voltage and the
iris, which are shown below
are a reference value. Because
there is a little difference, see
as the reference data.
