Blinking of the RELATIVE switch
When the lens iris position and the OCP IRIS control value become different, the
OCP-300 can indicate that condition with the RELATIVE switch blinking, depending on
the camera head firmware version. In this case, you can match the OCP IRIS control
value and the lens iris position by pressing the RELATIVE 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.
࣭ Difference in camera head operation depending on whether or not the camera head
supports the command
The camera head operation after pressing the REALTIVE switch partially varies
depending on whether or not the camera head
supports the command. When the camera
head does not support the command, the OCP IRIS control value is sent as the relative
data after the manual file clearance is sent. Therefore, there is a case that the position
moves greatly once from the iris position. On the other hand, when the camera head
supports the command, the difference between the lens iris position and the OCP IRIS
control value is subtracted from the manual file without clearing the manual file. With
this operation, the lens iris position and the OCP IRIS control value can be matched
without any additional movement.
