https://www.toshiba-teli.co.jp/en/Notes on using this product● 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. Moreover, during shooting under hightemperatures, vertical stripes or white spots (noise) may be produced, depending on the subject or camera
conditions (such as increased gain). However, such phenomena are not malfunctions.
● Check a combination with the lens
Depending on the lens and lighting you use, an image is reflected as a ghost in the imaging area. However,this is not because of a fault of the camera.
In addition, depending on the lens you use, the performance of the camera may not be brought out fully due
to deterioration in resolution and brightness in the peripheral area, aberration and others.
Be sure to check a combination with the camera by using the lens and lightning 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.
Install a next lens; its dimension of protrusion from bottom of the screw is equal to or less than 10 mm. If alens does not stand to this condition, it might not be installed to this camera.
C-mount lensBottom ofthe screw

10mm or less

● Mounting to pedestal
When mounting this product to a pedestal, make sure carefully that 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.
● 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.

communication.
Operation of this equipment in a residential area is likely to cause harmful interference in which casethe user will be required to correct the interference at his own expense.

[Phenomena specific to CMOS sensor]⚫

Defective pixels

A CMOS image sensor is composed of photo sensor pixels in a square grid array. Due tothe 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. Thisphenomenon, which is not a defect is exacerbated under higher temperatures and longexposure time.
⚫

Image shading
The brightness of the upper part of the screen may be different from that of the lower part. Notethat this is a characteristic of a CMOS image sensor and is not a fault.

Notes on Connection:- Please confirm the power supply of the camera off when plugging in or pulling out the I/O Connector. It causes thebreakdown.
- If your camera is used in a system where its connectors are subjected to strong repetitive shocks, its connectors are
possible to break down. If you use your camera in such a situation, use an USB3.0 cable with a lock screw, and secure
the camera cable as close as possible to the camera body for avoid physical shock to the camera connector.
- About e-CON cable: In the case that electric-wire is long or thin, input and output voltage may not satisfy specificationsof the camera or your system by voltage drop. Please confirm wires’ specifications before use them.

https://www.toshiba-teli.co.jp/en/Notes on 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.
- 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 camera, the projection distance from bottom of the screw should use
10mm or less.

Scalable
BU series provides the scalable mode that can read out defined area of the screen.
In the scalable mode, camera reads out only necessary area at the normal speed and reads out other area
at high speed. The frame rate can be faster when the vertical height size is small. However, the frame ratecannot be faster only when the horizontal width size is small.
Only single rectangle is selectable. Concave or convex shape is not selectable.

your application. Please refer to the TeliCamSDK for details.

Notes on Frame Drops of Image:
Depends on your PC or USB3.0 interface card configurations, images may not be captured normally (e.g. frame drops
may occur). In this case, change to frame rate setting lower.

This section describes trigger control of TriggerControl category for the BU series.
This camera series provides two kinds of exposure synchronization.
1. Normal Shutter mode

: Free run operation (internal synchronization)

2. Random Trigger Shutter mode

: Synchronized with external trigger input

In Random Trigger Shutter mode, two kinds of trigger input are available.
1. Trigger signal via the I/O connector (HardwareTrigger)
2. Trigger command via the USB interface (SoftwareTrigger)

DPCControl
This DPC (Defective Pixel Correction) function corrects defective pixels from the image sensor. Specifying X
and Y coordinates of the defective pixels, the defective pixels are corrected by calculation from the neighboring
pixels.

Then, set the index number for entry to “DPCIndex” register, and coordinates of defective pixels to“DPCEntryX”, “DPCEntryY” register. After setting coordinates, the defective pixel is corrected by
calculation from the neighboring pixels. In the case that there is a number of defective pixels, they can becorrected by pointing new DPCIndex and setting coordinates

Appendix
UserSetSave and UserSetQuickSave difference
If you want to change multiple Camera Settings (e.g. ROI setting) at once, UserSet feature is useful.
Application needs to save the camera settings in UserSet memory in advance or in initialization stage.
By UserSetSave, UserSet is stored to non-volatile flash memory.
It takes about 700ms to execute UserSetSave because Non-volatile flash memory needs to be erased
before writing. If you want to switch over multiple different settings in run time, overhead time of UserSetSave
is inevitable.

By UserSetQuickSave, UserSet is stored to internal RAM. It takes less than 100us in execution.
It can reduce the overhead time of UserSetSave greatly.
You can also save UserSets to Serial Flash if necessary by UserSetSave.

MultiFrame and Bulk function differenceThis section describes the difference between MultiFrame function of AcquisitionMode and Bulk function of
TriggerSequence.
- MultiFrame function sets limits to the number of frames to transfer with AcquisitionFrameCount register.
- Bulk function sets limits to the number of frames to exposure with TriggerAdditionalParameter register.

- MultiFrame function in Normal Shutter mode (TriggerMode = Off)
Camera transfers “AcquisitionFrameCount” frame(s).
AcquisitionMode = MultiFrame
AcquisitionFrameCount = 3
TriggerMode = Off
