USAGE PRECAUTIONS
 Handle carefully
Do not drop the equipment or allow it to be subject to strong impact or vibration, as such action may
cause malfunctions. Further, do not damage the connection cable, since this may cause wire
breakage.
 Environmental operating conditions
Do not use the product in locations where the ambient temperature or humidity exceeds the
specifications.
Otherwise, image quality may be degraded or internal components may be adversely affected. In
particular, do not use the product in areas exposed to direct sunlight.
 Combination of C-mount lens
Depending on the lens you use, the performance of the camera may not be brought out fully due to
the deterioration in resolution and brightness in the peripheral area, occurrence of a ghost,
aberration and others. When you check the combination between the lens and camera, be sure to
use the lens you actually use.
When installing a lens in the camera, make sure carefully that it is not tilted.
In addition, use a mounting screw free from defects and dirt. Otherwise, the camera may be unable
to be removed.
As for the C-mount lens used combining this product, the projection distance from bottom of the
screw should use 10mm or less.
10mm or less
C-mount lens
Bottom of
the screw
 Mounting to a pedestal
When mounting this product to a pedestal, make sure carefully that the lens doesn't touch with the
pedestal.
 Do not expose the camera’s image-pickup-plane to sunlight or other intense light directly.
Its inner CMOS sensor might be damaged.
 Occurrence of moiré
If you shoot thin stripe patterns, moiré patterns (interference fringes) may appear. This is not a
malfunction.
 Occurrence of noise on the screen
If an intense magnetic or electromagnetic field is generated near the camera or connection cable,
noise may be generated on the screen. If this occurs, move the camera or the cable.

USAGE PRECAUTIONS
 Handling of the protective cap
If the camera is not in use, attach the lens cap to the camera to protect the image pickup surface.
 If the equipment is not to be used for a long duration
Turn off power to the camera for safety.
 Maintenance
Turn off power to the equipment and wipe it with a dry cloth.
If it becomes severely contaminated, gently wipe the affected areas with a soft cloth dampened with
diluted neutral detergent. Never use alcohol, benzene, thinner, or other chemicals because such
chemicals may damage or discolor the paint and indications.
If the image pickup surface becomes dusty, contaminated, or scratched, consult your sales
representative.
 Disposal
When disposing of the camera, it may be necessary to disassemble it into separate parts, in
accordance with the laws and regulations of your country and/or municipality concerning
environmental contamination.
[Phenomena specific to CMOS sensor]
“This symbol is applicable for EU member states only”
 Defective pixels
A CMOS image sensor is composed of photo sensor pixels in a square grid array. Due to
the characteristics of CMOS image sensors, over- or under-driving of the pixels results in
temporary white or black areas (as if these are noises) appearing on the screen. This
phenomenon, which is not a defect is exacerbated under higher temperatures and long
exposure time.
 Image shading
The brightness of the upper part of the screen may be different from that of the lower part. Note
that this is a characteristic of a CMOS image sensor and is not a fault.

1. Overview
This BU CMOS series is an integrated-(one-body)-type camera that adopts a global shutter CMOS
sensor. These are BU205M (2M 2/3 type) BU406M (4M 1/1 type). There is BU406MN which was more
excellent in near-infrared (NIR) sensitivity in BU406M. Suffix [C] or [CF] are attached to the color
models. For video output and camera control, the USB 3.0 interface standard is adopted for high
transfer rate, and it is easy to integrate into industrial equipment.
2. Features
2.1 High frame rate
Supporting high frame rate, BU205M 170fps, BU406M/MN/MC 90fps.
2.2 Global shutter
As it employs a global electronic shutter similar to a CCD image sensor, clear images of even
fast-moving object are obtainable with less blur.
2.3 USB 3.0 interface
Video output and camera control are performed via the USB 3.0 standard interface. Data transfer
is up to 5Gbps (Maximum) that enables to output uncompressed video data at high frame rate.
2.4 USB3 Vision
This product is based on USB3 Vision Ver.1.0.
2.5 GenICam Ver.2.4, Ver.3.0
his product is based on GenICam (Generic Interface for Cameras) Ver.2.4 and Ver.3.0.
2.6 IIDC2 Digital Camera Control Specification Ver.1.1.0
This product is based on IIDC2 Digital Camera Control Specification Ver.1.1.0.
2.7 e-CON Connector adoption
The e-CON connector adoption enables to assemble the cable easily without using special tools.
2.8 Random Trigger Shutter
The Random Trigger Shutter function provides images in any timing by input of an external trigger
signal. Trigger control from PC is available as well.

5. Functions
5.1 Gain
Manual gain control is available up to 8 times.
Notes on gain setting:
Setting the gain value too high increases noises. When you adjust the brightness of the image, I ask
you to have final image quality checked with your environment.
5.2 Black Level
Black level is adjustable from -25% to +25% as white saturation level is 100%.
5.3 Gamma
Gamma correction curve is adjustable from 0.45 to 1.
5.4 LUT (Look up Table)
Arbitrary curve and binarization are possible by using 10 bit input and 10 bit output LUT.
5.5 Exposure Time
Manual exposure time control is available. Exposure time is adjustable by the internal sync signal.
5.6 White balance
Color models have two white balance modes, manual white balance (MWB) and one-push auto white
balance (OPWB). Select the mode to suit the subject and purpose.
5.6.1 MWB
R/B gain can be set independently.
5.6.2 OPWB
When OPWB is executed, the camera adjusts R/B gain automatically.

5.7 Random Trigger Shutter
An image is captured at the desired timing using trigger signal input. External trigger signal from
trigger input connector and software trigger from control command via the USB 3.0 interface are
available (Edge mode / Bulk mode). Trigger polarity is selectable (High active / Low active).
Note that Random Trigger Shutter will cause a delay between trigger signal and start of exposure.
See 7. Timing Chart for detail.
- Edge mode (TriggerSequence0)
The exposure time is determined by Exposure Time setting.

Notes on Random Trigger Shutter mode:
- In the period when FRAME_TRIGGER_WAIT signal is inactive, user must not input external trigger
signal to this camera.
- When the interval of the input trigger signal is extremely short, or when the trigger signal is noisy,
there is a possibility of causing the malfunction. In this case, please input a proper trigger signal.
