Functions of the XCL-V500
XCL-X700/V500
The speed of the electronic shutter is determined by
the frequency of the external input clock signals.
Calculate the shutter speed according to the following
formula.
Normal shutter speed:
Exposure time = { 685
×
A + 95
×
(A–1) + 187 }

External trigger pulse width shutter
speed:
• When trigger signals are input through the 12-pin
connector
Exposure time = { external trigger pulse width
+ 1
µ
s} + 144
×
2/ECLK
•When trigger signals are input through the DIGITAL
IF connector
Exposure time = { external trigger pulse width }
+ 144

Shutter speed = 1/Exposure time
Be aware that the external trigger pulse width should
be set in the range of 3
µ
sec to 1/4 sec when inputting
external clock signals.

Binning Function
Mixed signals for vertically adjacent pixels of the
output of the CCD are output in this function and
sensitivity and frame rate are approximately doubled.
When the Normal shutter is OFF in the Normal Mode,
the frame rate is doubled but exposure time is halved,
so that the effect of this function is cancelled out as in
the Reset/Restart mode. Both sensitivity and frame
rate are doubled when the Normal shutter is ON (1/100
s is not supported).
All modes are supported for the Camera Mode.
But High-rate scan II in Trigger Mode2 is not
supported.
