and GenICam V1.0 compliant.
Applied standards
Prosilica GX at a glance
GigE Vision®
GenICam™
The GigE Vision standard is an interface standard for digital machine vision
cameras administered by the Automated Imaging Association (AIA) that is widely
supported in the machine vision industry. In contrast, Gigabit Ethernet is the
network GigE Vision is built upon.
GenICam is a machine vision standard hosted by the European Machine Vision
Association (EMVA). The aim of GenICam is to provide a generic configuration
interface for cameras and devices independent of the used interface technology
(i.e. GigE Vision, USB3 Vision, DCAM IEEE1394, Camera Link). This approach
enables proper interoperability between GenICam compliant hardware and
software solutions without the need for customization.
The GenICam standard consists of multiple modules that specify tasks to be solved.
Allied Vision cameras and software make use of these modules, like the Standard
Feature Naming Convention (SFNC) that standardizes feature names and types via
an XML file or the transport layer interface (GenTL) that is used to grab images.

This chapter describes the components required for
your vision system including configuring the host
computer, Ethernet adapter settings, and connecting
your Prosilica GX camera.
Prosilica GX Technical Manual V2.3.117
Configuring the host computer
Allied Vision GigE Vision cameras can operate on 10/100 or Gigabit speed Ethernet
adapters. In order to reach the maximum camera frame rate, a Gigabit speed
Ethernet adapter with jumbo packet support is required.
If your host computer has an available Ethernet interface, this can be used with
Allied Vision GigE cameras. We recommend that your camera system uses a
dedicated Ethernet interface not shared with Internet or local area networks. If
more ports are needed, or your existing Ethernet adapter is unable to operate at
Gigabit Ethernet speeds, installing additional hardware may be required.
Usage on mixed-use networks (with printers, Internet/email, etc.) is possible but
may impact camera performance (e.g., framerate). Check with your IT
administrator if required for network configuration.
Installing the Ethernet adapter driver
Installation and hardware
Install the network card driver from your network card manufacturer. If no
installation application is provided, update the driver manually.
To update the driver manually
1.Click the Start icon and select Control Panel in the menu.
2.Click View by Large Icons and select Device Manager in the list.
3.Under Network Adapters, locate the Ethernet network adapter, right-click the
entry, and select Update Driver Software in the menu.
4.Select the Search automatically for updated driver software or Browse my computer for driver software.
5.Click Close once the driver has been installed.
Optional: Modifying Ethernet adapter IP
address
After initial Ethernet adapter hardware installation, connect the Ethernet adapter
directly to the camera. The default configuration assigns an IP address
automatically using the Link-Local Address range of 169.254.xxx.xxx or an address
defined by the DHCP server, if present.
Users can fix the adapter address to minimize the time required for a camera to be
recognized by the host application. Systems that employ multiple Ethernet
adapters connected to multiple cameras will also be required to fix the address of
the Ethernet adapter.
To connect to the camera, edit the host PC’s adapter settings and configure the
following settings:
•IP Address: 169.254.100.1
•Subnet mask: 255.255.0.0
•Default gateway: blank

Connecting your camera
Use a Category 6 or higher rated Ethernet cable to connect the camera to the host
adapter. Crossover cabling is not required but does work. The camera has circuitry
to determine if a crossover cable is being used.
Allied Vision recommends Category 6 (Cat 6) or higher rated Ethernet cables. A
different rating may not sustain peak interface bandwidth; leading to lost
connectivity or image data coming from the camera.
Installation and hardware
Contact your Allied Vision Sales representative or your local Allied Vision
distribution partner for information on accessories.
A camera power adapter for each GigE camera is available from Allied Vision. See
Specifications on page 22 for connector definition and voltage specifications.
For Prosilica GX cameras
•Use only DC power supplies with insulated cases.
•For all power connections use only shielded cables to avoid electromagnetic
interferences.
Connecting to host application
Once you have installed the Vimba Viewer or third-party application to your host
computer, you can connect your Allied Vision GigE camera via an Ethernet cable
and connect the Hirose cable to power the camera.

Notes on specifications
Read first
For some Prosilica GX cameras, e.g. Prosilica GX1910, Prosilica GX2300, bandwidth
limiting occurs even in 8-bit pixel formats, although not as severely as with a 16bit pixel format.
Dimensions and mass
Dimensions include connectors but not the tripod and lens.
Mass does not include the tripod and lens.
Modular options
Prosilica GX cameras can be ordered with several modular options including lens
mount, optical filter, and sensor options. For more information, see the Modular Concept.
Specifications
Monochrome models
As monochrome models do not have an optical filter always attach a dust cap
when a lens is not attached to minimize the possibility of contaminants falling on
the sensor surface.
Mono8
Prosilica GX color models include the Mono8 monochrome pixel format in addition
to color and RAW formats.
ON Semiconductor sensor change
Prosilica GX color models with ON Semiconductor sensors now use sensors with
the new Gen 2 CFA materials. For more information, see the Product Change Notification on the Allied Vision website.
Resolution and ROI frame rates
This section provides performance information about the impact of reducing the
region of interest on the camera’s maximum frame rate. In addition, because the
Prosilica GX camera offers dual GigE LAG, the impact of using a single Ethernet
connection versus dual Ethernet connections with the host is compared.
Single interface GigE connection with the Prosilica GX
When a Prosilica GX camera is connected to the host computer using a single
Ethernet connection, it behaves like a single interface GigE Vision camera. The total
bandwidth available for the camera is 125 MB or 1 Gb. A dual GigE LAG connection
supported by the Prosilica GX camera offers up to 250 MB or 2 Gb of bandwidth.

Bandwidth limited
Bandwidth limiting of frame rate
There are several factors that limit the frame rate of a camera, for example, input
trigger speed and mode, exposure time, sensor readout time, and available
bandwidth. For the following discussion and charts we assume input trigger
settings and exposure time are set so as not to limit the frame of the camera. This
leaves sensor readout time, the time to physically output the charge off a camera
sensor, and available bandwidth. In most cases, the sensor readout time dictates
the true frame rate of a camera, unless the amount of transmitted data exceeds
what is available on the GigE interface.
In the example chart below, the frame rate for a 16-bit pixel format is given on a
Prosilica GX1050 camera. The upper line shows the frame rate in dual GigE mode,
where no bandwidth limitation occurs. The lower line shows the frame rate in
single GigE mode, where bandwidth limitation occurs after a data threshold of 124
Mbit/s. This is the shaded region below, occurring at an image height greater than
200 pixels.
Figure 1: Illustration of bandwidth limiting: frame rate vs. height for Prosilica
GX1050 in single interface GigE configuration - 16-bit pixel format
24Prosilica GX Technical Manual V2.3.1
Specifications
The Prosilica GX camera can be operated near peak sensor frame rates even when
using a single interface connection. The frame rate vs. height graphs included in
this section provide frame rate performance results for both single GigE interface
and dual GigE LAG configurations at 8-bit or 16-bit output formats.
Resolution and ROI measurements
•Frame rate data was generated using
StreamBytesPerSecond = 124 MB/s
and 8/16-bit pixel format
– 8-bit pixel formats: Mono8, BayerRG8, or BayerGR8
– 16-bit pixel formats: Mono12, BayerRG12, or BayerGR12
Frame rates may be lower if using network hardware incapable of 124 MB/s.
•ROIs are center image, where attribute
OffsetY = (full sensor height – ROI
height)/2, for maximum speed advantage on a quad-tap CCD sensor.
•The camera frame rate can be increased by reducing the camera's height
attribute, resulting in a decreased region of interest (ROI) or “window”.
•The camera frame rate can also be increased by increasing the camera's
BinningVertical attribute, resulting in a vertically scaled image (less
overall height with same field of view).
•There is no frame rate increase with reduced width.

Isolated IO GND
This connection provides the user ground reference and return path for the In 2,
Out 3, and Out 4. It is also recommended that the ground wiring be physically close
to the used In/Out to prevent parasitic coupling. For example, a good cable design
would connect the required signal on one conductor of a twisted pair and the
Isolated IO GND on the second conductor of the same twisted pair.
RxD RS232 and TxD RS232
These signals are RS232 compatible. These signals allow communication from the
host system via the Ethernet interface to a peripheral device connected to the
camera. Tie RS232 ground to Camera GND to complete the RS232 circuit.
RS232
For complete RS232 description and usage, see the RS232 Port application note at:
The isolated out power connection provides power for isolated signals Out 3 and
Out 4. The voltage requirement is 5 to 24 V DC. The current requirement for this
supply is a function of the optical isolator collector current and the number of
outputs used in the system. Isolated Out Power wiring should be physically close to
Out 3 / Out 4 wiring to prevent parasitic coupling.
Input triggers
In 1 and In 2
In 1 and In 2 allow the camera to be synchronized to some external event. These
signals are optically isolated and require the signal common (Isolated IO GND). The
camera can be programmed to trigger on the rising or falling edge of these signals.

The lens control connector is a Hirose 3260-8S3. This connector provides the
signals necessary to control the iris, focus, and zoom of most commercially
available TV Zoom and Video-type auto-iris lenses. The cable side connector is
Hirose 3240-8P. The camera can be configured to operate lenses with unipolar
voltage requirements of 6 to 12 V or lenses that operate with bipolar voltages from
±6 V up to ±12 V. This voltage level can be controlled through software. The default
voltage is set to 6 V. The current capacity for each axis is 50 mA.

Auto iris video-type connection
Prosilica GX cameras provide built-in auto iris controls for controlling video-type
auto-iris lenses. These lenses are available from many popular security lens
companies including Pentax, Fujinon, Tamron, Schneider and others.
Remote iris lens control allows the camera to be more adaptable to changing light
conditions. It allows the user to manually control the exposure and gain values and
rely solely on the auto iris for adjustment to ambient lighting.
Voltage specification
Camera interfaces
The following diagram uses CAMERA POWER to power the video iris lens, and
assumes CAMERA POWER = 12 V. Most video iris lenses operate at a 8 to 16 V input
voltage. Therefore, this circuit is not appropriate if using a 24 V camera power
supply. Doing so may irreparably damage your lens. Please consult your video iris
lens specifications for the appropriate drive voltage.

Table 49: Explanation of signals in timing diagram
Trigger rules
User trigger pulse
The user trigger pulse width should be at least three times the width of the trigger
latency.
•The end of exposure will always trigger the next readout.
•The end of exposure must always end after the current readout.
•The start of exposure must always correspond with the interline time if readout is true.
•Exposure start delay equals the readout time minus the registered exposure
time.
Triggering during the Idle State
For applications requiring the shortest possible Trigger Latency and the smallest
possible Trigger Jitter the User Trigger signal should be applied when Imaging is
false and Idle is true. In this case, Trigge r Latency and Trigger Jitter are as indicated
in the camera specifications.
99Prosilica GX Technical Manual V2.3.1
Camera interfaces
i
Triggering during the Readout State
For applications requiring the fastest triggering cycle time whereby the camera
image sensor is exposing and reading out simultaneously, apply the User Trigger
signal as soon as a valid Trigger Ready is detected. In this case, Trigger La tency and
Trigger Jitter can be up to 1 row time since Exposure must always begin on an
Interline boundary.
For a more detailed description of the trigger concept for advanced users and
special scenarios, see the Triggering Concept application note:
