The diagram below shows the connections between the Watec USB Camera and a PC. Please use aconversion connector separately according to the USB port of the PC to which the camera is connected.

Fig.1 Watec USB Camera – PC Connection Example
It is recommended to use a PC with a USB 2.0 port and a Windows 10 32 / 64bit or later OS installed.
The Watec USB Camera is compatible with USB Video Class.
When the Watec USB Camera is connected to a PC for the first time, the driver will be installed
automatically. If the driver installation does not occur, and the Watec USB Camera is not recognized by
the PC, please check to make sure that the connection is correct, and please check that the PC
requirements are met.
It is possible to acquire videos on a PC with an OS of XP or earlier, but some functions are limited.
Please refer to Section 3 “Functions and Settings” for details.
Please connect the camera to the PC, and after confirming that the camera is recognized, please start theviewer software and begin the Preview/Capture of video.

53. Functions and Settings
The Watec USB Camera settings are separated into Video Capture Pin, which is used to set the output
image size, and the Video Capture Filter, which is used to set the image brightness and color.
This section explains each of the functions of the Watec USB Camera and their respective setting
methods using the WatecCameraViewer (Watec USB Camera Capture Software which can be
downloaded from our company’s website, http://www.watec.co.jp/ ) as an example.

The resolution is higher than MJPG, however, the frame rate is limited as described in
the later section.
MJPG: Output video is compressed with MJPG(Motion-JPEG) format. The resolution will
decrease, however, the frame rate will be maintained even at the maximum image size.

*fps: Frames per Second, the number of frames processed per second in a video image,
the higher frame rates produce smoother, more fluid video.

is set with 320x240 or 640x480.
On the WAT-08U2 / WAT-09U2, 60fps is available when the image size 1280x720 and lower isselected.
It crops and outputs a read area of the image sensor when 60fps is selected. In order to crop andoutput the central part of the screen, the angle of view is different from other frame rates.

The default setting is "ON" (checked box). When Low Light Compensation is "ON", the camera
will decrease the shutter speed to increase sensitivity, if the camera judges that there is notenough illumination. In this mode, the frame rate will decrease.
*The shutter speed does not change due to Low Light Compensation when the frame rate is
7.5fps on WAT-03U2 / WAT-03U2D.
*The shutter speed does not change due to Low Light Compensation when the frame rate is 5fps

Almost all functions are set from the Video Capture Pin or Video Capture Filter, and Camera Control.
However, “Sensor Sense” can be set only from the Camera Control window.
3.5.1.Sensor Sense
The default setting is “HIGH”. When the setting is “LOW”, the sensitivity of the image censor ishalf in the “HIGH” setting. “LOW” setting is effective in the very bright areas, such as in the
sunlight.
This function is available for WAT-05U2M / WAT-06U2 / WAT-06U2D / WAT-07U2 / WAT-07U2D /WAT-08U2 / WAT-09U2.

4. GPIO Connection
The WAT-01U2 / WAT-03U2/ WAT-06U2 / WAT-07U2 has a 2 pin GPIO (General Purpose Input/Output)
connector at the back of the camera. Currently, an external trigger for capturing Snapshot is assigned tothis connection.

*The WAT-02U2D / WAT-03U2D / WAT-05U2M / WAT-06U2D / WAT-07U2D / WAT-08U2/ WAT-09U2 doesn't have this function.
4.1.Snapshot Function
To use the GPIO Snapshot function, refer to the figure below to connect the 2-pin cable to thecamera GPIO connector and use a push button switch as the trigger is recognized by closing of thecircuit.
When the button is pressed (circuit is closed), the camera will stop the video capture and switch tothe static image capture. A static image approximately 1 second after the button is pressed will be
output. Thereafter, the camera will revert back to the video capture.
From the time when the button is pressed until the Snapshot is output, the camera will adjust the
exposure and white balance. During this time, please note that a good Snapshot may not be
captured, if the environment changes, such as lighting conditions.

4.1.1.Method to Confirm Operation (saving of static image)The saving of the image file captured by the Snapshot function is done by using theWatecCameraViewer (available for download from our website: http://www.watec.co.jp/).
While the WatecCameraViewer is open, and the video image can be previewed, shorting the GPIO
circuit will save a Snapshot to an image file (.jpg or .bmp).
(The image file will be saved in the same folder as where the WatecCameraViewer is operating)
The same Snapshot function can be operated from the WatecCameraViewer.
(Capture->Trigger for Still Capture)*Please heed caution to the following when using the WatecCameraViewer in the Windows
Vista/7/8/8.1/10/11 OS environments:
・When starting the program from C:¥ProgramFiles¥.. with UAC (User Account Control) enabled,
make sure to start up the WatecCameraViewer with Administrator rights, as creating and saving of
new files in this folder/directory tree is not permitted without Administrator rights. (Right Click on
WatecCameraViewer executable file -> Run as administrator)
Please refer to the following section for setting of the image file to be saved.
