(5-2) Setting of shutter speed
The shutter speed is determined by assigning "0 - 9" to the shutter switch position or specifying the shutter speed in H
(Horizontal scan time) unit.
As this camera is not equipped with the substantive shutter setting switch, the shutter speed is specified by changing the
Feature settings regarding the exposure time of GenICam API or using the serial communication command via serial
communication software.
The shutter speed setting is mainly decided by setting position "0" to "9" of (Hypothetical) shutter switch.

(Note) (H) and (V) in the table represent the horizontal time unit and the vertical time (frame duration) unit respectively.
(Note) "No shutter" in the table means the continuous shutter mode with exposure time = 1 frame duration.
(Note) The value of the each shutter speed is the factory default value. The shutter speed of each position (excluding
shutter position = 0) is possible to change by the user with serial communication command.
(!) As for this camera, "Pulse width control time/asynchronous" must be set to be "Pulse width control (PWC) =
ENABLED".
When it is set to be "Pulse width control (PWC) = DISABLED" (default), the selection can be made out of the 9 levels
not only for the continuous shutter operation but also for the asynchronous shutter operation.
(!)
"Shutter switch" means the hypothetical shutter switch set on the memory inside the camera via serial communication
command.
[Explanation]
The shutter speed is specified by reading out the value on the electronic shutter table (separately exist on page A to F )
corresponding to the set position of shutter switch.(excluding directly designated value )
The electronic shutter table can all be rewritten with the serial command "E" (shutter table Edit command) except shutter switch "0"..
