6. Absolute Value Iris Control 6-2
6.1 Clearing the Iris Manual File
Conventionally, the iris manual files controlled by the MCP had been automatically
cleared as required when the MCP and the BS/CCU of OCP is connected in parallel.
In case of OCP-300, there are cases that the manual files are not automatically cleared
depending on the network connection and the control panel concurrently connected.
This is not a failure and is a proper system operation. In addition to automatic clearing,
it is also possible to clear manually.
When the manual file is added in other panel, the OCP IRIS control value and the lens
iris position become different, and the failure may occur during the operation. In that
case, you can clear the manual file by pressing the RELATIVE switch.
In addition, when valid/invalid of the IRIS variable range setting knob is switched by
pressing the FULL switch, the manual file is cleared.
࣭ Blinking of the RELATIVE switch
Adding of the relative data from other control panel (condition that the data is in the
manual file) can be indicated by blinking the OCP-300 RELATIVE switch depending on
the camera head firmware version. Even in this condition, the manual file can be
cleared by pressing the RELATIVE switch or the FULL switch.
In addition, the blinking function of the RELATIVE switch can be disabled.
Reference
: Refer to "21.1.3 Setting Items" for detailed description of the setting.
6.2 Auto Iris Operation
During the auto iris operation, fine adjustment of approximately ± 1 stop for the F value
for auto iris control value is possible by using the IRIS control knob regardless of the
FULL switch condition. In addition, the actual fine adjustment is the additional value
with the control from other control panel.
6.3 Initial Mode
In the power supply is OFF, and during OFF of the enable, the FULL switch status is
kept the same. Because this mode uses the absolute data control, there is a case that the
iris value jumps depending on the IRIS control knob position.
