Pulse Train Generator
Pulse waveforms can be output from the GPO2/3
connector. Available range is 0.5Hz to 100kHz.
Status LED
The LED-on, blinking, or LED-off condition of the LED
on the rear panel is as follows:
Temperature Readout
Function
The camera’s internal temperature can be read from the
temperature sensor installed in the circuit board. Its
accuracy is ±2°C. Use this value as a general guide.
If the interval of the temperature sensor value is set to a
value other than 0, the temperature information can be
transmitted to a PC application as an event data.
Sensitivity Control
The VSUB (substrate bias voltage) in the CCD can be
changed*
1
. VSUB adjustment allows you to change the
Qs (saturation signal charge) value. Increasing the
VSUB has the effect of improving the sensitivity*
2
.
Therefore, when capturing a dark image but the
exposure time cannot be extended, this has the effect of
improving the image quality. On the other hand,
decreasing the VSUB has the effect of reducing image
smearing. The factory setting is adjusted to the optimal
value.

Not including XCG-C130 and XCG-C130C

If Qs exceeds the maximum signal charge amount
that can be transferred vertically and horizontally, a
transfer error will occur, resulting in image smearing,
etc.
User Set
Main set values can be saved to the channels 1 to 16 of
USERSET. Refer to “Command List” (page 37) for
items to be saved. The factory setting is saved to channel
0, which cannot be overwritten.
Setting example (1):
Shutter is 3 ms, Gain is 3 dB, Pulse signal is output to
GPO3 connector (this setting is saved to the channel
1).
ExposureTime=3000
Gain=3
LineSelector=Line3
LineMode=Output
LineSource=PWM
UserSetSelector=1
UserSetSave
Setting example (2):
The user set saved in the channel 2 is loaded.
UserSetSelector=2
UserSetLoad
User set memory
This is one of the items to be saved in the user set
channel. Signed 32-bit numbers are assigned to slots 0 to
15.
