Introduction
Precautions
Caution
Caution
Caution
Caution
Do not disassemble the camera housing. Warranty is void if
camera has been disassembled.
This camera contains sensitive internal components.
Keep shipping material.
Poor packaging of the product may cause damage during
shipping.
Verify all external connections.
Verify all external connections in terms of voltage levels,
power requirements, voltage polarity, and signal integrity
prior to powering the device.
Cleaning.
This product can be damaged by some volatile cleaning agents.
Avoid cleaning the image sensor unless absolutely necessary.
Please see instructions on optics cleaning in this document.
Caution
Do not exceed environmental specifications.
See environmental specifications limits in the Specifications
section of this document. Special care must be taken to
maintain a reasonable operating temperature. If the camera
is operated in temperatures higher than the specified range,
the camera should be mounted on a heat sink.
AVT does not warranty against any physical damage to the sensor/filter/protection glass or lenses. Use utmost care when cleaning optical components.
Caution
Do not touch any optics with fingers. Oil from fingers can
damage fragile optical coatings.
Identifying debris
Debris on the image sensor or optical components appears as a darkened area
or smudge on a camera image. Do not confuse this with a pixel defect which
appears as a distinct point.
Locating debris
First determine whether the debris is on the sensor glass, IR filter (if used), or
lens. The farther away the debris is from the sensor, the blurrier the debris
appears on a camera image.
Stream a live image from the camera using a uniform target, such as a piece of
paper. To determine if the debris is on the camera lens, rotate the lens independent of the camera. If the spot moves, the debris is on the lens. Otherwise, the
debris is on the IR filter (if used) or sensor glass.
Color cameras with IR filter
Prosilica GT color cameras are equipped with an IR filter. With no lens or lens
cap on a camera, the IR filter is exposed and debris can accumulate on it. This is
the most probable location for debris. It should not be necessary to remove the
IR filter for cleaning. Clean the outside of the IR filter glass using the techniques explained in the next section. If it is determined that the debris is on the
inside surface of the filter glass, or on the sensor glass, IR filter removal is necessary.
Note
•A pin spanner wrench (AVT P/N: E9020001) suitable
for IR filter removal is available for purchase from
AVT for all Prosilica GT cameras except Prosilica GT
large format cameras.
•DO NOT attempt to remove the camera IR filter for
Prosilica GT large format cameras. Please contact
support@alliedvisiontec.com for assistance.

Introduction
Cleaning with air
Blow directly on the contaminated surface with moderate pressure, clean compressed air.
Caution
View a live image with the camera after blowing. If debris is still present, repeat
the process until it is determined that the particulate cannot be dislodged. If
this is the case, proceed to the contact cleaning technique.
Do not exceed 6 bar (90 psi). If using canned air, approximately ~ 4.8 bar (70 psi) when full, do not shake or tilt the
can, as extreme changes in temperature due to sudden cold
air can crack the optic glass.
Contact cleaning
Only use this method if the above air cleaning method does not sufficiently
clean the surface. Use 99% pure isopropyl alcohol and clean cotton swabs. Wet
the swab in the alcohol. Quickly wipe the optics in a single stroke. Prolonged
exposure of alcohol on the swab can cause the swab glue to loosen and transfer
to the optic glass. Do not reuse the same swab. Repeat this process until the
debris is removed. If this process fails to remove the debris, contact AVT.

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

I/O definition
Camera Power
The Prosilica GT camera can be powered through the Hirose I/O port, via Pin 1
Camera GND and Pin 2 Camera Power, or through the Gigabit Ethernet port if
using a power over Ethernet (PoE) supported network card, switch, or injector.
Cameras powered by both the Hirose I/O port and the Gigabit Ethernet port will
use the power provided by Hirose I/O port only.
Pin 2, Camera Power, supports an input voltage range of 7–25 VDC. The camera
will not power in reverse polarity. Exceeding the 25 V will damage the camera.
Note
A 12 V power adapter with Hirose connector is available for purchase from AVT:
•AVT P/N 02-8003A North America Supply
•AVT P/N 02-8004A Universal Supply
Isolated IO ground
The Isolated IO GND connection provides the user ground reference and return
path for In 2, Out 3, and Out 4. It is recommended that the ground wiring be
physically close to the In/Out wiring to prevent parasitic coupling. For example, a good cable design connects In 2 to one conductor of a twisted pair, Iso-lated IO GND to the second conductor of the same twisted pair.
RxD RS-232 and TxD RS-232
These signals are RS-232 compatible. These signals are not optically isolated.
Tie RS-232 ground to Camera GND to complete the RS-232 circuit. Communica-
tion is at 11520 baud.
The Isolated Out Power connection provides power for isolated signals Out 3
and Out 4. The voltage requirement is 5–24 VDC. 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.

Camera interfaces
Input triggers
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 – non-isolated
In 1 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 Camera GND to complete
the trigger circuit.
Caution
Exceeding 5.1 V on In 1 can permanently damage the camera
In 2 – opto-isolated
In 2 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 2 has a longer
propagation time. It can be driven from 5 to 24 V with a minimum current source of 5 mA.
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 above events.
GPOUser programmable binary output.

output signal is a low voltage TTL, maximum 3.3 V. Not suitable for driving
loads in excess of 50 μA.
Out 3 and 4 – opto-isolated
Out 3 and Out 4 signals are optically isolated and require the user to provide a
voltage level, Isolated Out Power. Tie signal ground to Isolated IO GND to
complete the external circuit. Isolated Out Power can be configured between
5–24 V. An example of the functional circuit is indicated in the following diagram.

Lens control
Prosilica GT standard and long cameras
Prosilica GT standard and long cameras can be used with C-/CS-Mount auto iris
lenses of DC type, and P-Iris type.
Both DC and P-Iris lens types use the same standard connector, shown left,
located on the side of the camera. Lens type is automatically determined by the
camera on power-up. Connecting the lens after the camera is powered will not
damage the lens, but it will not be recognized by the camera; therefore, the relevant camera control attributes will not function. If this occurs, disconnect and
reconnect the camera power supply.

DC-Iris lenses
The Prosilica GT standard and long cameras operate with any standard DC-type
auto iris lens. AVT tested lenses include Fujinon DV10x8SA-SA1L, Computar
HG2Z0414FC-MP, and Pentax C61227DCPS.
DC-type auto iris lenses are continuously driven by a voltage (0–3.3 V) from the
camera lens control port. This voltage level determines whether the lens opens
or closes, and is calculated based on the applicable iris camera attributes.
Operation
1.Connect a DC-Iris lens to the camera before powering up the camera.
2.Power up camera, and open camera control software.
3.Set camera to live image with desired ExposureValue and GainValue attri-
butes.
4.Set IrisMode = DCIris. Camera uses an automatic algorithm to determine
correct lens iris position based on the IrisVideoLevel attribute.
5.If lens operation is too slow or oscillates, see LensDCDriveStrength.

DC-Iris controls are described further in the following documents:
PvAPI users: AVT GigE Camera and Driver Attributes document
VIMBA users: AVT GigE Camera and Driver Features document
P-Iris lenses
P-Iris (Precise iris) lenses allow the camera to adjust to an exact F-number without drift, through the usage of a stepper motor. The host system knows the
exact position of the iris at all times, allowing for a closed loop feedback system.
Operation
1.Connect a P-Iris lens to the camera before powering up the camera.
2.Power up camera, and open camera control software.
3.Set camera to live image with desired ExposureValue and GainValue attri-
butes.
4.Set LensPIrisFrequency as specified by lens documentation, or in supported P-Iris lens list, as described in the next section. All P-Iris lenses
tested thus far operate well between [100-200].
5.Set LensPIrisNumSteps as specified by lens documentation, or in supported P-Iris lens list, as described in the next section.
6.Set IrisMode attribute to PIrisAuto or PIrisManual. PIrisAuto uses an
automatic algorithm to determine correct LensPIrisPosition based on the
IrisVideoLevel attribute. PirisManual allows manual control of LensPIrisPosition.

Trigger rules
Note
The user trigger pulse width should be at least three times the
width of the trigger latency as indicated in chapter
Specifications on page 13.
•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 expo-
sure 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 indi-
cated in the camera Specifications section.
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.

Firmware update
Firmware update
Firmware updates are carried out via the GigE connection. AVT provides an
application for all Prosilica GT cameras that loads firmware to the camera using
a simple interface. New feature introductions and product improvements motivate new firmware releases. All users are encouraged to use the newest firmware available and complete the firmware update if necessary.

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. However, in cases where a camera is limited by frame rate
due to bandwidth restrictions, a reduction in width will give a frame rate
increase. Cameras with a “burst mode” frame rate (see chapter Specifications on
page 13) are able to output more data than the maximum available bandwidth
(124 MB/s), and will see a frame rate increase with a reduction in width.
Note
•Data was generated using StreamBytesPerSecond = 124
MB/s (full bandwidth) and an 8-bit pixel format. Frame
rates may be lower if using network hardware incapable
of 124 MB/s.
•For maximum speed advantage on quad-tap CCD sensors,
ROIs are center image, where attribute RegionY = (full
sensor height – ROI height)/2.
•There is no frame rate increase with reduced width.
•BinningY is horizontal row summing on CCD before readout. The frame rate for an ROI at the same effective
height as binning will be slower because the CCD still
needs to read out the “fast readout rows” in ROI mode.
There is no frame rate increase with reduced width.

For maximum speed advantage ROIs are taken as center image, where attribute RegionY = (full sensor height – ROI height)/2.
