SFNC V1.2.1 compliant.
Applied standards
Prosilica GC at a glance
GigE Vision®
GenICam™
The GigE Vision standard is an interface standard for digital machine vision
cameras administered by the 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 EMVA. The aim of GenICam is
to provide a generic configuration interface for cameras and devices independent
of the used interface technology (for example, GigE Vision, USB3 Vision, DCAM
IEEE 1394, 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 SFNC that
standardizes feature names and types via an XML file or the transport layer
interface (GenTL) that is used to grab images.

21Prosilica GC Technical Manual V2.4.1
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 port, this can be used with Allied
Vision GigE cameras. We recommend that your camera system uses a dedicated
Ethernet port not shared with Internet or local area networks. If more ports are
needed, or your existing Ethernet adapter is unable to operate at GigE speeds,
installing additional hardware may be required.
Usage on mixed-use networks (with printers, Internet, email) is possible but may
impact camera performance (for example, 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.

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

NOTICE
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.
Frame memory
Normally, an image is captured and transported in consecutive steps. The image is
taken, read out from the sensor, digitized and sent over the GigE network. Prosilica
GC cameras are equipped with an image buffer. The memory operates according to
the FIFO principle. Specification tables show how many frames can be stored by
each model.
Number of frames

Resolution and ROI frame rate
This section charts the resulting frame rate from changing sensor height from full
image to a single line. Unless otherwise noted, sensors do not give an increase in
readout speed with a reduction in width.
Resolution and ROI measurements
•Data was generated using
bandwidth) and an 8-bit pixel format. Frame rates may be lower if using
network hardware incapable of 124 Mbps.
•ROIs are taken as center image for maximum speed advantage, where feature
OffsetY = (full sensor height – ROI height)/2.
BinningVertical is horizontal row summing on CCD before readout. The
•
frame rate for an ROI at the same effective height as binning is slower because
the CCD still needs to read out the “fast readout rows” in ROI mode.
Frame rate and readout
StreamBytesPerSecond = 124 Mbps (full
Although the sensor is capable of higher frame rates, readout is limited by GigE
bandwidth and exposure value. You can improve frame rates with a reduced ROI
and shorter exposure values.
Absolute QE plots
Important notice before reading the QE plots
All measurements were done without protection glass or IR cut filter. With
protection glass or filters, QE decreases by approximately 10%.
The uncertainty in measurement of the QE values is 10.25%. This is mainly due
to uncertainties in the measuring apparatus itself (Ulbricht sphere, optometer).
Manufacturing tolerance of the sensor increases overall uncertainty.
Absolute QE plots for Sony CCD sensors
Sony provides relative response curves in their sensor data sheets. To create the
absolute QE plots shown in this chapter, the relative response was converted to a
normalized QE response and then adjusted as per three measured QE values (at
448 nm, 529 nm, 632 nm) for color sensors and one measured QE value (at 529
nm) for monochrome sensors.
Absolute QE plots for ON Semi CCD sensors
The curves in the absolute QE plots shown in this chapter are from the sensor
manufacturer data sheet. The information was correct at the time of publishing.
Sensor specifications may change without notice.

Wavelength
The wavelength range in the absolute QE plots is based on the information
available in the sensor manufacturer data sheet at the time of publishing. Many
color sensors are documented by the sensor manufacturer only for wavelengths
from 400 nm to 700 nm.
For additional wavelength information, contact the sensor manufacturer.
Spectral response plots
Sony provides relative response curves in their sensor data sheets. To create the
spectral response plots shown in this chapter, the relative response was adjusted

All Prosilica GC color models are equipped with an infrared block filter (IR cut
filter). This filter is employed to prevent infrared light from passing to the sensor. In
the absence of an IR filter, images are dominated by red and incapable of being
properly color balanced. Monochrome models do not employ an IR cut filter.

Isolated IO ground
The Isolated IO GND connection provides the user ground reference and return
path for In 1, and Out 1. It is recommended that the ground wiring be physically
close to the I/O wiring to prevent parasitic coupling. For example, a good cable
design connects In 1 to one conductor of a twisted pair, Isolated IO GND to the
second conductor of the same twisted pair.
RxD RS232 and TxD RS232
These signals are RS232 compatible. These signals are not optically isolated. Tie
RS232 ground to Signal GND to complete the RS232 circuit.
Further information available online
For complete RS232 description and usage, see the RS232 Port GigE Cameras
application note:
Input triggers allow the camera to be synchronized to an external event. The
camera can be programmed to trigger on the rising edge, falling edge, both edges,
or level of the signal. The camera can also be programmed to capture an image at
some programmable delay time after the trigger event.
In 1 (opto-isolated)
In 1 is optically isolated and can be used in electrically noisy environments to
prevent false trigger events. Tie trigger ground to Isolated IO GND to complete the
trigger circuit. Compared to the non-isolated trigger, In 1 has a longer propagation
time. It can be driven from 5 to 24 V with a minimum current source of 10 mA. See
Camera I/O opto-isolated user circuit example for wiring information.
In 2 (non-isolated)
In 2 is not electrically isolated and can be used when environmental noise is
inconsequential and faster trigger response is required. The required trigger signal
is low voltage TTL 3.3 V. Tie trigger ground to Signal GND to complete the trigger
circuit. See Camera I/O non-isolated user circuit example for wiring information.
NOTICE
Input voltage limit
Exceeding 5.1 V on In 2 can permanently damage the camera.
62Prosilica GC Technical Manual V2.4.1
Camera interfaces
Output signals
Output signals can be assigned to a variety of internal camera signals via software.
They can be configured to active high or active low. The internal camera signals are
listed as follows:
ExposingCorresponds to when camera is integrating light.
Trigger ReadyIndicates when the camera is ready to accept a trigger signal.
Trigger InputA relay of the trigger input signal used to daisy chain the
trigger signal for multiple cameras.
ReadoutValid when camera is reading out data.
ImagingValid when camera is exposing or reading out.
StrobeProgrammable pulse based on one of the previously listed
events.
GPOUser programmable binary output.
Out 1 (opto-isolated)
Out 1 signal is optically isolated and requires a user voltage with a suitable pull up
resistor. Tie signal ground to Isolated IO GND to complete the external circuit. See
the Camera I/O opto-isolated user circuit example for wiring information.
Out 2 (non-isolated)
Out 2 signal is not electrically isolated and can be used when environmental
electrical noise is inconsequential and faster trigger response is required. Use
Signal GND to complete the external circuit. The output signal is a low voltage TTL,
maximum 3.3 V. Not suitable for driving loads in excess of 24 mA. See the Camera
I/O opto-isolated user circuit example for wiring information.
Signal ground
Signal Ground must be connected to the user’s external circuit ground if In 2 or Out
2 is to be used, or if the RS232 port is to be used. Note that Signal Ground is
common with Camera GND; however, it is good practice to provide a separate
ground connection for power and signal.
Video iris
This signal can be used to drive the video input of a video iris lens. See the Video
iris output section for wiring information.
Reserved
These signals are reserved for future use and should be left disconnected.
Video iris output
Prosilica GC 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, and Schneider.

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.
NOTICE
Camera power
The following schematic 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. Consult your video iris
lens specifications for the appropriate drive voltage.

Trigger rules
User trigger pulse
The user trigger pulse width should be at least three times the width of the trigger
latency as indicated in Specifications.
•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, Trigger Latency and Trigger Jitter are as indicated
in the camera Specifications section.
68Prosilica GC Technical Manual V2.4.1
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 Latency 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:

Important instructions to be read first
Read these instructions before you contact Allied Vision or your Allied Vision
distribution partner for assistance.
Contact Allied Vision or your Allied Vision distribution partner if you are not
familiar with the procedures described in this chapter.
Warranty information available online
For details about camera warranty duration and sensor warranty terms, go to:
https://www.alliedvision.com/en/support/warranty
Warranty precaution
To ensure your warranty remains in effect:
•Do not open the camera housing.
•Follow instructions described in this chapter.
•Use only optical quality tissue or cloth if you must clean a lens or filter.
•Use only optics cleaner. Do not use aggressive cleaners like benzine or spirit.
Such cleaners may destroy the optical component’s surface.
•Do not use compressed air which can push dust into camera and lens unless
you are trained to clean a camera using this method.
Allied Vision does not warranty against any physical damage to the sensor, filter,
protection glass, or lenses. Use utmost care when cleaning optical components.
Warranty precaution
Allied Vision does not warranty against any physical damage to the sensor, filter,
protection glass, or lenses. Use utmost care when cleaning optical components.
Keep optical components clean
The best way to ensure the camera remains clean is to avoid penetration of foreign
substances into the camera.
When screwing or unscrewing the camera lens or dust cap, hold the camera with
the mount opening towards the floor. This minimizes the possibility of any
contaminants falling on the glass surface. Always store cameras and lenses with
dust-caps on.
72Prosilica GC Technical Manual V2.4.1
Identifying impurities
If you observe any image artifacts in your video preview of your Prosilica GC
camera you may have impurities either on the lens, filter or protection glass, or on
the sensor protection glass. Every Prosilica GC camera is cleaned prior to sealing
and shipment; however, impurities may develop due to handling or unclean
environments.
As shown in figure 31, impurities (dust, particles or fluids) on the sensor or optical
components appear as a dark area, patch or spot on the image and remain fixed in
the preview window while you rotate the camera over the target.
Do not confuse this with a pixel defect which appears as a distinct point. Particles
can either rest loosely or can be more or less stuck to the optical surface.
Cleaning optical components
Figure 31: Image with tiny dust on the filter (left) and dust on the sensor (right)
Locating impurities
Before you dismount the lens you should find out if the impurity is on the filter,
lens, or sensor.
1.Start acquiring a uniform image (for example, a white sheet of paper) with the
camera.
2.To identify the affected surface, move the suspected optical component and
see if the contamination follows this movement.
a.If you move only the lens (not the camera) and the impurity moves as
well, the impurity is on the lens.
b.If you move the IR cut filter or protection glass window and the impurity
moves as well, the impurity is on the filter or protection glass. Carefully
remove the filter or protection glass and clean it on both sides using the
techniques explained in the next section. If the impurity is neither on the
lens nor the IR cut filter or protection glass, it is probably on the sensor.
Removing IR cut filter
A pin spanner wrench (Allied Vision order code: E9020001) suitable for IR filter
removal is available for purchase from Allied Vision for all Prosilica GC cameras.
NOTICE

Cleaning optical components
Materials for cleaning optical components
Use only these cleaning materials for optical components
•Optic approved lens cotton, cloth, or tissue that is chemically pure and free
from silicones and other additives.
•Optic approved low residue cleaning liquid.
NOTICE
Never use these cleaning materials for optical components
•Dry swabs or tissue may cause scratches.
•Metal tools may cause scratches.
•Disposable cotton cosmetic swabs may contain contaminants harmful to
optical glass.
•Cosmetic cotton my cause scratches or get caught in small gaps.
•Consumer eyeglass cleaning cloths may be pretreated with silicone harmful to

•Aggressive cleaners like benzine, acetone, or spirits may damage the surface.
Optical cleaning liquid material safety data sheets
Read the MSDS for the optical cleaning liquid before cleaning your camera and
optics. The MSDS provides important information including hazard identification,
first aid measures, handling and storage, and PPE.
Cleaning Instructions
Workplace conditions
•Perform all cleaning operations (lenses, filter or protection glass, and sensor)
in a dust-free clean-room.
•Avoid touching the optical components with your fingers or any hard material.
•Nitrile cleanroom gloves or powder free latex gloves are recommended to
maintain low particulate levels.
•Use an ESD mat to prevent damage from an electrostatic discharge.
1.Unplug the camera from any power supply before cleaning.
74Prosilica GC Technical Manual V2.4.1
Cleaning optical components
2.Apply a small amount of cleaning liquid to a new lens cleaning cotton, cloth, or
tissue. The cotton, cloth, or lens tissue should be moist, but not dripping.
3.Hold the camera sensor diagonally upwards. Ensure that the camera is away
from your body to prevent particles like skin flakes from falling on the sensor.
4.Wipe the glass surface with a spiral motion from the center to the rim.
Normally, several spiral wipes are recommended. Wipe only on glass avoiding
contact to metal surfaces, because microscopic dirt could be released and
could cause scratches on the glass.
5.When you have finished cleaning, examine the surface in a strong light. Take
an out-of-focus picture of a flat, illuminated surface to see if any dirt or dust
remains.
6.If dust spots remain, repeat this procedure using new clean lens tissue (as
described).
Cleaning issues
If you notice that the camera lens or sensor is not clean after attempting to clean
twice, or if you have any questions regarding cleaning your camera, contact your
Allied Vision distribution partner or Allied Vision support.
