Functions
Partial Scan
Only the area selected from the effective pixel area can
be read out. Clearing unnecessary parts at high-speed
allows high-speed reading. The area size is selected by
the HEIGHT and WIDTH commands, and the read
beginning point is selected by the OFFSETX and
OFFSETY commands. Using the ROI command, you
can set HEIGHT, WIDTH, OFFSETX and OFFSETY at
the same time. Reducing HEIGHT increases the frame
rate, but changing WIDTH does not change the frame
rate. Partial scan can be set with or without a trigger.
Binning can be used at the same time.
OFFSETX and OFFSETY relate to WIDTH and
HEIGHT as follows:
O WIDTH
≤
WIDTH (maximum value)
O HEIGHT
≤
HEIGHT (maximum value)
When selecting sensor tap4, a central line divides the
screen into two halves symmetrically for a vertical
division. For the relationship between OFFSETY and
HEIGHT, see the following formula:
OFFSETY × 2 + HEIGHT = Maximum lines
(For XCL-S600 the maximum number of lines is 2208,
for XCL-S900 the maximum number of lines is 2712)
Because the value of OFFSET is set automatically by
HEIGHT and the maximum number of lines, the
command to change OFFSETY is not available.
(Example of XCL-S900)
>SENSOR-TAP 4
>HEIGHT 480
t
HEIGHT is 480, OFFSETY is set to
1116 ( = (2712 – 480) ÷ 2)
>OFFSETY 0
t
OFFSETY change not available.
Note
Since the shutter setting has priority, use a shutter speed
high enough to enable partial scan at a higher frame rate.

OFFSETX, WIDTH: 2-step increments
OFFSETY, HEIGHT: 4-step increments
Binning
By adding 2 vertical pixels or 2 horizontal pixels, the
frame rate in vertical binning is increased along with the
sensitivity. The color camera cannot set this. This can be
set with or without a trigger. Partial scan can be used
concurrently and horizontal and vertical can be set at the
same time.
Sensor Tap
Switching sensor tap
This unit has a CCD with 4-channel output which is
available for 4-channel, 2-channel and 1-channel
reading. The reading speed becomes faster as the value
of the channel number increases.
