Notes on cable configurations
The presence of lighting equipment and television receivers nearby may result in video and audio
noise. In such cases, change the cable configurations or placement.
Notes on attaching the lens
Avoiding dust particles
When attaching the lens to the camera, stray dust and other particles may adhere to the sensor
surface and rear surface of the lens. Be careful of the following when attaching the lens.
•Work in a clean environment.
•Do not remove the caps from the camera and lens until immediately before you attach the lens.
•To prevent dust from adhering to surfaces, point the camera and lens downward and do not allow the
lens surface to come into contact with your hands or other objects.
•Always use a blower brush to remove any dust that adheres.
Never use your hands or cloth, blow with your mouth, or use other methods to remove dust.
Phenomena specific to CMOS image sensors
The following phenomena are known to occur on cameras equipped with CMOS image sensors. These
do not indicate malfunctions.
•Aliasing
When shooting straight lines, stripes, and similar patterns, vertical aliasing (zigzag distortion) may
appear on the monitor.
•Blooming
When strong light enters the camera, some pixels on the CMOS image sensor may receive much
more light than they are designed to hold, causing the accumulated signal charge to overflow into
surrounding pixels.
This “blooming” phenomenon can be seen in the image, but does not affect the operation of the
camera.
•Fixed pattern noise
When shooting dark objects in high-temperature conditions, fixed pattern noise may occur
throughout the entire video monitor screen.
•Defective pixels
Defective pixels (white and black pixels) of the CMOS image sensor are minimized at the factory
according to shipping standards. However, as this phenomenon can be affected by the ambient
temperature, camera settings (e.g., high sensitivity and long exposure), and other factors, be sure to
operate within the camera’s specified operating environment.
Notes on exportation
When exporting this product, please follow the export regulations of your country or region.

GO-5100M-USB / GO-5100C-USB
Features
The GO-5100M-USB/GO-5100C-USB is an industrial progressive scan camera equipped with a
2/3-inch global shutter CMOS image sensor with 5.1 effective megapixels (2464 × 2056). The unit is
compact and lightweight in design and is equipped with USB 3.0 interface.
The GO-5100M-USB produces monochrome output while the GO-5100C-USB produces Bayer output.
Compact and lightweight
The unit’s compact (approx. 29 × 29 × 41.5 mm, excluding lens mount) and lightweight (approx. 46 g)
design allows for easy assembly and installation.
Output formats
You can choose from 8-bit, 10-bit, and 12-bit* output for both monochrome and Bayer.
* As the color camera cannot perform white balance when using 12-bit output, perform white balance on the
application.
High frame rate
The GO-5100M-USB and GO-5100C-USB are both capable of frame rates of up to 74 fps (8-bit format)
for full 5.1-megapixel output. Even faster frame rates can be achieved when a smaller ROI (region of
interest) is specified.
ALC (automatic level control) function
Combine the automatic gain control and automatic exposure control functions to allow handling of
changes in various brightnesses.
Variety of pre-process functions
•LUT (lookup table)
For programmable control over gamma and contrast.
•Gamma correction
Gamma can be set to 0.45, 0.60, or 1.0 (off).
•Shading correction (flat field and color shading)
Non-uniformity (i.e., shading) in the amount of light generated by the lens and lighting equipment can
be corrected.
•Bayer white balance (GO-5100C-USB only)
White balance can be automatically adjusted continuously. It can also be adjusted manually using R,
and B gain.

•The diagonal of the camera’s CMOS image sensor is 11 mm, the size of standard 2/3-inch lenses.
To prevent vignetting and to obtain the optimal resolution, use a lens that will cover the 11 mm
diagonal. Some lens manufacturers offer lenses with an 11 mm format. If not, a 2/3-inch lens is
recommended.
Caution
•The maximum performance of the camera may not be realized depending on the lens.
•Attaching a lens with a mount protrusion of 9.1 mm or longer may damage the lens or camera.
Note
The following formula can be used to estimate the focal length.
focal length = WD / (1 + W/w)
WD: Working distance (distance between lens and object)
W: Width of object
w: Width of sensor (8.5 mm on this camera)

Exposure Auto* Off
* This item is only enabled when [Exposure Mode] is set to [Timed].
Caution
When [Exposure Mode] is set to [Off], [Trigger Mode] cannot be set to [On]. Other settings may also be restricted
depending on the exposure mode, so be sure to set the exposure mode before configuring the trigger settings.
■Control via External Triggers
When Controlling the Exposure Time Using Specified Exposure Times
Configure the settings as follows.
Item Setting value / selectable range
Trigger Selector (trigger operation) Frame Start
Trigger Mode On
Trigger Source (trigger signal source) Any
Trigger Activation (trigger polarity) Rising Edge (rising edge of input signal), Falling Edge (falling
edge of input signal)
Exposure Mode Timed (control via exposure time)
Exposure Time 8 bit: 7 to 7999920(µs)*1
10/12 bit: 8 to 7999900(µs)*1
Exposure Auto Off, Continuous
1Set [Exposure Mode] to [Timed].
([Timed] is the default setting.)
* 1 The minimum value will differ depending on the [Pixel Format] setting value.
The actual exposure time will consist of the image sensor’s offset duration (13.7 μs) added to the
setting configured on the camera.
When [ExposureMode] is set to [Timed] and the exposure time is set to 7 μs, the actual exposure
time will be as follows.
7 μs + 13.7 μs (offset duration of image sensor) = 20.7 μs
When [ExposureMode] is set to [TriggerWidth], the exposure is slightly longer than the width of the
trigger signal. To achieve an exposure time of 20.7 µs and the exposure time offset is 13.7 µs, use
20.7 µs - 13.7 µs = 7 µs as the high or low time for the trigger signal.

2Specify the exposure time in [Exposure Time].
The setting value for the exposure time can only be changed when [Exposure Auto] is set to [Off].
If [Exposure Auto] is set to [Continuous], temporarily set it to [Off] before changing the exposure
time.
3Set [Trigger Selector] to [Frame Start].
([Frame Start] is the default setting.)
4Set [Trigger Mode] to [On].
5If necessary, change the [Trigger Source], [Trigger Activation], and [Exposure Auto]
settings.
When Controlling the Exposure Time using the Pulse Width of the Trigger Input Signal
Configure the settings as follows.
Item Setting value / selectable range
Trigger Selector (trigger operation) Frame Start
Trigger Mode On
Trigger Source (trigger signal source) Any
Trigger Activation (trigger polarity) Level High (high-level duration), Level Low (low-level
duration)
Exposure Mode Trigger Width (control via trigger width)
1Set [Exposure Mode] to [Trigger Width] .
When you select [Trigger Width], [Trigger Mode] will automatically be set to [On].
2Set [Trigger Selector] to [Frame Start].
([Frame Start] is the default setting.)
3If necessary, change the [Trigger Source] and [Trigger Activation] settings.
Other controls
In addition to exposure time, the following can also be controlled by external triggers. Select these
control operations in [Trigger Selector].
[Trigger Selector] setting Description
Acquisition Start Start image acquisition.
Acquisition End Stop image acquisition.
Acquisition Transfer Start Output acquired images at a specified timing. (Up to 8
frames for 8-bit, and up to 4 frames for 10-/12-bit.)

Step 5: Adjusting the Image Quality
Adjusting the Gain
Adjust the sensitivity via the analog gain (i.e., master gain).
For details on gain control, see “Gain Control” (page 29) in the “Main Functions” section.
■Manual adjustment
1Expand [Analog Control], and set [Gain Auto] to [Off].
([Off] is the default setting.)
2Configure the gain.
uExpand [Analog Control], and select the gain you want to configure in [Gain Selector].
•For the GO-5100M-USB, only [Analog All] (master gain) can be configured.
•For the GO-5100C-USB, [Analog All] (master gain), [Digital Red] (digital R gain), and [Digital
Blue] (digital B gain) can be configured individually.
vConfigure the gain value in [Gain].
•[Analog All] (master gain) can be set to a value from x1 to x16 (0 dB to +24 dB). The
resolution is set in x0.01 steps (0.005 dB to 0.08 dB depending on the setting value). Values
are configured by multipliers.
•For the GO-5100C-USB, the [Digital Red] (digital R gain) and [Digital Blue] (digital B gain)
can be set to a value from x0.45 to x5.62 (–7 dB to +15 dB) the [Analog All] (master gain)
value. The resolution is set in x0.01 steps.
