7-1 7. Relative Value Iris Control
7. Relative Value Iris Control
With the relative value iris control, the iris is controlled by the relative data as the
control of the MCP. During the relative value iris control, the RELATIVE switch lights
on. This control method is adopted for the initial setting of the network. You can switch
between "absolute value iris control" and "relative value iris control" by using the panel
configuration.
The actual iris control uses the additional value from other control panel.
When adding of the relative data is not conducted on other panel, the operation becomes
the same on a superficial level as the absolute value iriscontrol.

possible.
When the FULL switch is on, controlling the entire iris operation range is possible by
using the IRIS control knob.
When the FULL switch is off, iris adjustment is possible within the range that is set
with the IRIS variable range setting knob. Set the center position of the iris operation
by using the RANGE knob. Set the oscillation from the center position, where is set with
the SENSE knob. Iris adjustment is available within the range set with the RANGE
and SENSE knobs by using the IRIS control knob.
7.1 Clearing the Data of Other Control Panel
When the relative data from other control panel is added, the OCP IRIS control value
and the lens iris position becomes different, and the failure such as the knob becomes
effective only one side may occur during the operation. You can solve this condition by
using the knob free function. However, you can also solve this condition by clearing the
relative data from other control panel to match the OCP IRIS control value and the lens
iris position.
You can send the command that clears the manual file by pressing the RELATIVE
switch. After clearing the manual file, send the IRIS control value, which is determined
by the OCP IRIS control knob and the IRIS variable range setting knob positions, as the
relative data. By executing this operation, the camera manual file can be set to the
control value from the OCP only.
In addition, when valid/invalid of the IRIS variable range setting knob is switched by
pressing the FULL switch,you can match the OCP IRIS control value and the lens iris
position.

free function.
