Freeset sequence (except XCG-CG40)
You can perform multiple (maximum 10 patterns) exposure and
GPO output with 1 trigger signal.
The start time and length as well as the gain of exposure and GPO
output can be set to any value.
The set sequence of exposure and GPO output is established as 1
cycle, and this cycle can be repeated.

Trigger Inhibition
Trigger input can be disabled. This function is effective when
disabling the trigger signal to a specific camera in the environment
where multiple cameras are connected by the same trigger
signal and when preventing false operations caused by noise
contamination to the trigger signal line (due to the installed
environment).

Trigger Range Limit
Only signals in the set trigger width can be accepted as the trigger
signal. This functions as a noise filter, which removes chattering or
disturbance noise in the trigger signal line. When the trigger signal
is input, exposure is started with the time lag of the trigger range
setting values. Image will not be output, when trigger signal width is
out of set range.

Overlap trigger
The trigger signals can be accepted during the sensor readout
signals are asserted.
If the trigger cycle overs the maximum value of the frame rate,
images are distorted.
Set FastTriggerMode to OFF for XCG-CG160/CG160C and XCG-
CG510/CG510C.

User Set
Main set values can be saved to the channels 1 to 16 of USERSET.
User set is available during special trigger mode (Bulk Trigger/
Sequential Trigger).
Gain
Manual gain
The manual gain can be finely set in 0.1 dB units or bit levels.
Although the settable lower/upper limit values of the gain are
slightly different in each camera, the gain parameter value can be
set from –1 dB or less to 27 dB or more.
Auto gain (AGC)
By setting AUTOGAIN, the gain is automatically adjusted according
to the image pickup environment.
AGC works so that the average level in a detection frame may
reach AGC-LEVEL. The AGC detection frame is set to the central
region by default. The detection frame can be displayed or the
detection area changed.
Frame Rate Control
Auto frame rate
The reading cycle is set to allow the frame rate to be the maximum
value automatically according to the current shutter setting and the
partial scan setting in the free-run operation (Shutter has priority).
The next exposure is performed while outputting a video and the
next video output is started immediately after finishing all video
outputs. The frame rate is lowered when setting the shutter time
longer than the video output time.
Specifying frame rate
The frame rate of the video output can be specified in the free-run
operation. The value of the frame rate [fps] should be entered. The
frame rate faster than the fastest frame rate cannot be set.
Look-Up Table (LUT)
The camera's look-up table consists of 4,096 values, with 12-bit
input and output. The look-up table allows setting an arbitrary
gamma curve or binarization. Also, a gamma curve coefficient
can be specified for the standard black level. For levels below the
standard black level, set the gamma value to 1 to prevent burnt-out
highlights in the black level.
