Introduction
Caution
Caution
Cleaning optics
Caution
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.
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.
Prosilica GC Technical Manual V2.0.8

Introduction
Color cameras with IR filter
Prosilica GC 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. Depending on the manufacturing date of your Prosilica GC camera, the IR filter may be slot type, or pinhole
type. Slot type filters can be removed using a small flat head screw driver. Pinhole type filters require a pin spanner wrench for removal.
Note
A pin spanner wrench suitable for IR filter removal is available
for purchase from AVT.
AVT P/N: E9020001
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.
Contact cleaning
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.
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.

Filter
All Prosilica GC 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.
The figure below shows the filter transmission response for the IRC30 filter
employed in the Prosilica GC cameras.

Cameras are shipped with adjustable C-Mount or CS-Mount
depending on sensor size and camera order code. See AVT Modular Concept for more information:
Use an adjustable wrench to loosen the locking ring. Be careful not to scratch
the camera. When the locking ring is loose, unthread the ring a few turns from
the camera face.
Note
A wrench suitable for this procedure is available for purchase
from AVT.

Image to infinity
Use a C-Mount compatible lens (CS-Mount compatible lens, if using CS ring)
that allows an infinity focus. Set the lens to infinity and image a distant object—
10 to 15 m should suffice. Make sure the lens is firmly threaded onto the CMount ring. Rotate the lens and C-Mount ring until the image is focused. Carefully tighten the locking ring and recheck focus.

Note
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 In/Out 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.
For more information on the power voltage range update for
the Prosilica GC family:
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.
Caution
Exceeding 5.1 V on In 2 can permanently damage
the camera.
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.
Prosilica GC Technical Manual V2.0.8

Camera interfaces
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 cir-
cuit. See 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
Camera I/O non-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 RS-232 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 Video iris
output description section for wiring information.
Reserved
These signals are reserved for future use and should be left disconnected.

Video iris output description
Prosilica GC cameras provide built-in auto iris controls for controlling videotype auto-iris lenses. These lenses are available from many popular security
lens companies including Pentax, Fujinon, Tamron, Schneider, etc.
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.
Caution
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 8–16 V input voltage. There-
fore, 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.

Camera I/O non-isolated user circuit example
Figure 38: Prosilica GC non-isolated user circuit
Caution
Input: Incoming trigger must be able to source 10 µA,
at 3.3 V. Input trigger voltage greater than 5.5 V will
damage the camera.
Output: The maximum sync output current is 24 mA,
at 3.3 V.
The non-isolated trigger circuit is connected to a Texas Instruments
SN74LVC2G241 buffer/driver inside the camera. See the Texas Instruments
SN74LVC2G241 for more detailed information.

Camera trigger
TermDefinition
Trigger readyIndicates to the user that the camera will accept the
next trigger
Registered exposure time Exposure time value currently stored in the camera
memory
Exposure start delayRegistered exposure time subtracted from the read-
out time and indicates when the next exposure
cycle can begin such that the exposure will end
after the current readout
Interline timeTime between sensor row readout cycles
ImagingHigh when the camera image sensor is either
exposing and/or reading out data
IdleHigh if the camera image sensor is not exposing
and/or reading out data

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 12.
•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 GC 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 region of
interest (ROI), from full image to a single line.
Note
•Frame rate data was generated using StreamBytesPerSecond = 124 MB/s and an 8-bit pixel format such as
Mono8, BayerBG8, or BayerRG8. Frame rates may be
lower if using network hardware incapable of 124 MB/s.
•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 BinningY attribute, resulting in a vertically scaled image (less overall height with same field of
view).
•There is no frame rate increase with reduced width.
