Product Precautions
Handle the camera with care. Do not abuse the camera. Avoid striking or shaking it. Improper handling or
storage could damage the camera.
Do not pull or damage the camera cable.
During camera use, do not wrap the unit in any material. This will cause the internal temperature of the unit
to increase.
Do not expose the camera to moisture, or do not try to operate it in wet areas.
Do not operate the camera beyond its temperature, humidity and power source ratings.
While the camera is not being used, keep the lens or lens cap on the camera to prevent dust or
contamination from getting in the Sensor or filter area and scratching or damaging this area.
Do not keep the camera under the following conditions:
In wet, moist, and high humidity areas
Under hot direct sunlight
In high temperature areas
Near an object that releases a strong magnetic or electric field
Areas with strong vibrations
Apply the power that satisfies the requirements specified in this document to the camera.
Use a soft cloth to clean the camera. Use pressured air spray to clean the surface of the glass. DO not
scratch the surface of the glass.
The camera is a general-purpose electronic device; using the camera for the equipment that may threaten
human life or cause dangers to human bodies directly in case of failure or malfunction of the camera is not
guaranteed. Use the camera for special purposes at your own risk.

Product Specifications and User’s Guide
1) FrameTriggerWait
The user can check the camera condition (camera exposure and image output processing by the
trigger signal with this FrameTriggerWait signal).
This signal is LOW for the period from the trigger input signal to the image output.
a) High status (3.3V): No processing by the trigger signal. The camera accepts the trigger signal.
b) Low status (0V): The camera is exposed and the image output processes by the trigger signal.
The camera default setting is the input trigger signal is INVALID while at the low status of this signal.
When the exposure starts while the image output by the next trigger signal, please change the
camera setting (Device code: 00H, Command No. : 13H) to accept the trigger signal while the
image outputs.
The noise appears on the image when the exposure begins while the image is output. The noise
appears on the image when the start exposure while the image is output. In this case, please
change the “H reset” for the exposure start mode (Device code: 00H, Command No. : 12H) to
change the exposure start point to the next HD timing.
2) UserOutput
The status of the UserOutput signal can change with the “UserOutputValue”.
3) ExposureActive
The user can check the exposure time with the ExposureActive signal.
4) TriggerAuxiliary
The TriggerAuxiliary signal is the input trigger signal.
5) TriggerInternal
The TriggerInternal signal is the input trigger signal with the trigger delay time.
6) SensorReadOut
The SensorReadOut signal is the FVAL signal, which is the image output period of the time.
7) StrobeSignal
The StrobeSignal signal is the strobe control signal.
