Features
GigE Vision compliant
This unit supports GigE Vision Ver.2.0/Ver.1.2, and the
versions are switchable by changing the settings.
IEEE1588 compliant
This precision clock synchronization via network
protocol conforms to the defined IEEE1588 standard.
This unit can synchronize the exposures of multiple
cameras via an Ethernet cable.
External trigger shutter function
By synchronizing with an external trigger signal, any
shutter timing can be used.
Partial scan
The camera module can limit the number of video
output lines to achieve high frame rates, enabling highspeed image processing.
Body fixing
The screw holes to install the camera module are located
under the front panel (the image sensor reference plane).
Installing the camera module on the front panel
minimizes deviation of the optical axis.
LUT (Look Up Table)
You can switch to OFF or ON. When set to ON, you can
select from five preset values, such as inversion,
binarization, settable five-point approximations, etc.
Switching an Output Bit Length
You can select 8-bit output, 10-bit output, or 12-bit
output.
For color models, you can also select an output of RGB
24-bit, YUV 24-bit (YUV444), or YUV 16-bit
(YUV422).
High image quality
This unit produces stable output images, by adopting the
latest CMOS image sensors with a global shutter
function.
By adopting the square pixel image sensor, images can
be processed using the original aspect ratio without a
converting procedure.
The following models and resolutions of their image
sensors are shown below.

You can adjust the R and B level against G level to adjust
the white balance. This unit is also equipped with the
one-push white balance function, by which the camera
can automatically adjust the white balance.
Area gain function
You can set the gains between 0 to 32 times for a
preference position (up to 16 positions). If the set area is
duplicated, the low-numbered area takes priority.
Equipped with temperature sensor
This unit can readout the temperature inside of the
camera from the temperature sensor installed on the
module board. If the update interval of the temperature
sensor value is set to other than 0, the temperature
information can be sent to a PC application as event
data.

Phenomena Specific to
Image Sensors
Binning function (XCG-CG160 only)
Adding 2 pixels in the vertical and horizontal directions
achieves higher sensitivity and frame rate.
Note
The following phenomena that may occur in images are
specific to image sensors.
They do not indicate a malfunction.
White flecks
Although the image sensors are produced with highprecision technologies, fine white flecks may be
generated on the screen in rare cases, caused by cosmic
rays, etc.
This is related to the principle of image sensors and is
not a malfunction.
The white flecks especially tend to be seen in the
following cases:
• when operating at a high environmental temperature
• when you have raised the gain (sensitivity)
• when using the slow shutter
Aliasing
When fine patterns, stripes, or lines are shot, they may
appear jagged or flicker.

When mounting the camera
When the value read from temperature sensor is above
75 °C (167 °F), heat dissipation is required.
* For CG160/CG160C, in addition to the above
condition, use in environments where the difference
with the ambient temperature is 34°C or less.
To promote heat dissipation from the unit and maintain
performance, mount the camera to a metallic heat
dissipation plate.
Dimension of the heat dissipation plate: 160 mm ×
130 mm × t5 mm or more (Thermal conductivity:
16.3 W/m·K or more)
Plate that prevents heat dissipation
(made of wood, resin, etc.)
Notes
• When mounting the camera to the heat dissipation
plate, secure the camera tightly by using the reference
screw holes (see page 7) and screws.
• Do not mount the camera to a plate made of a material
such as wood or resin that prevents heat dissipation.

Connections
Network Settings
For the camera to be connected to a network, the
following address data must be properly specified:
• IP address
• Subnet mask
• Default gateway
The camera provides the following three methods for the
address data setting:
• Using Persistent IP
• Using DHCP
• Using Link Local Address (LLA)
Using Persistent IP
Use this method when the IP address to be assigned to
the camera has been specified in advance. When you use
a fixed IP, setting of subnet mask is necessary. To use
beyond the router, you need to set the default gateway as
well.
Packet Delay
The delay amount to be inserted between packets can be
set when sending them to a network. By increasing the
packet delay, you can reduce the network bandwidth that
the camera uses for sending packets. However, as the
amount of data sent in a certain time is decreased with
increased delay, the frame rate of output images of the
camera may be consequently decreased.
Using DHCP
The camera is equipped with a function to automatically
obtain an IP address by communicating with a DHCP
server on a network. When using the DHCP method for
IP address setting, the subnet mask and default gateway
values automatically obtained from the DHCP server are
also used.
Using LLA
If neither Persistent IP nor DHCP is used, or if an IP
address cannot be obtained from the DHCP server, the
IP address is determined by LLA. The IP address
determined by LLA will be 169.254.XXX.YYY, with
XXX and YYY automatically specified.
Packet Size
The amount of image data per packet can be set in bytes.
To permit the camera to operate properly, set the packet
size to a value less than the MTU of the network device
connected to the camera. Set the largest value in the
networks including the hub.
10
Network connection
speed
This unit supports the connection with 1000Base-T
(1 Gbps) or 100Base-TX (100 Mbps).
When you connect the unit to the network, negotiate the
communication speed with the connected equipment
and start communication at a higher speed of that both
equipment are compatible with.
When using the unit with 100Base-TX connection, the
frame rate to be output is limited, because the output
data band width from the camera becomes narrow
compared to the 1000Base-T connection.
The camera has a buffer to store multiple images and all
of the shot images are stored once in the buffer.
The stored images are output from the camera in order
starting from the oldest image in the buffer.
Therefore, if the frame rate during shooting is faster than
the frame rate that can be output from the camera, the
image data will always be stored in the buffer, and the
time interval from shooting to image output becomes
large.
To avoid this situation, it is required to set the shooting
frame rate to the proper value when using 100Base-TX
connection.
The data rate of images is obtained by the following
formula:
Notes
• Any persistent IP address can be entered, but the
camera may become unable to be detected, depending
on the IP address setting. If this occurs, use a tool for
issuing ForceIP and set a persistent IP address again.
• When setting the parameters (Width, Height, and
PixelFormat) for calculating the payload size, stop
camera image output beforehand.
Data rate = Width
× Height × BPP × FPS

FPS: Frame rate [frame/sec]
It is possible to minimize delay by using the camera at a
frame rate where the data rate becomes low with a
margin against 100 Mbps.

Note
• When inputting a trigger signal to the camera using the DC-700/CE, use DC 5 V or less at the logical high level.
• Make sure to supply power to the camera module and confirm that the camera module is operating before inputting a
trigger signal. If you input trigger signal to a camera module without the power supplied, this may cause a malfunction
of the camera module.

Functions
Binning (XCG-CG160
only)
Partial Scan
Only the area selected from the effective pixel area can
be read out. Adding 2 pixels of vertical and horizontal
directions achieves higher sensitivity and frame rate.
The area size is selected by the Height and Width
registers, and the read beginning point is selected by the
OffsetX and OffsetY registers. Reducing Height
increases the frame rate, but changing the Width register
does not change the frame rate. Partial scan can be set
with or without a trigger.
OffsetX and OffsetY relate to Width and Height as
follows:
OffsetX + Width
OffsetY + Height
Note
Since the shutter setting has priority, use a shutter speed
high enough to enable partial scan at a higher frame rate.
