Introduction
Cleaning optics
Caution
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 the sensor glass.
Color cameras with IR filter
Prosilica GX 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 GX 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.
Prosilica GX Technical Manual V2.0.8
10
Introduction
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.

Filters
All Prosilica GX 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 GX cameras.

The Gigabit Ethernet port conforms to the IEEE 802.3 1000BASE-T standard for
Gigabit Ethernet over copper. AVT recommends using Category 6 or higher compatible cabling and connectors for best performance.
The Prosilica GX offers two Gigabit Ethernet ports. This interface is enabled
using Link aggregation. A link aggregation group (LAG) is automatically configured on the camera when both ports are connected. The host computer requires
a dual port, LAG capable Ethernet adapter. The LAG group needs to be configured by the user.

I/O definition
Camera Power
The Prosilica GX camera family supports a wide input power voltage range. The
camera will not power in reverse polarity. Exceeding the voltage range specified
below will damage the camera.
Caution
5–24 V. 12 V nominal.
Note
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 physi-
cally 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 RS-232 and TxD RS-232
A 12 V power adapter with Hirose connector can be
ordered from AVT:
•AVT P/N 02-8003A North America Supply.
•AVT P/N 02-8004A Universal Supply.
These signals are RS-232 compatible. These signals allow communication from
the host system via the Ethernet port to a peripheral device connected to the
camera. Tie RS-232 ground to Camera GND to complete the RS-232 circuit.
The Isolated Out Power connection provides power for isolated signals Out 3
and Out 4. The voltage requirement is 5–24 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.

Table 16: Prosilica GX lens connector definition
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 6–12 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.
Caution
Do not exceed the lens manufacturers voltage specification.
Note
This cable side Hirose connector can be purchased from AVT.

Video iris connection
Prosilica GX 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 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.
Caution
This diagram 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. 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.
Verify lens voltage setting on camera does not exceed lens
voltage specification. Camera lens voltage is controlled by
software. This is set to 6 V after power up and cannot be saved
to user configuration files. Current capacity per axis = 50 mA.

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.
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 GX 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 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 port 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 port 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 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 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
Mb/s. This is the shaded region below, occurring at an image height greater
than 200 pixels.

Resolution and ROI frame rates
Note
For some GX cameras, e.g. GX1910, GX2300, bandwidth limiting occurs even in 8-bit pixel formats, although not as severely
as with a 16-bit pixel format.
The Prosilica GX camera can be operated near peak sensor frame rates even
when using a single port connection. The frame rate vs. height graphs included
in this section provide frame rate performance results for both single GigE port
and Dual GigE LAG configurations at 8-/16-bit output formats.
Note
•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 Bayer-
GR12
Frame rates may be lower if using network hardware incapable of 124 MB/s.
•ROIs are center image, where attribute RegionY = (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 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.
