Item 1: GIGABIT ETHERNET PORT
This port conforms to the IEEE 802.3 1000BASE-T standard for Gigabit Ethernet over copper.
It is recommended that CAT5E or CAT6 compatible cabling and connectors be used for best
performance. Cable lengths up to 100m are supported.

rear view. 14 GND SIGNAL
The General Purpose I/O port uses a 3M 10214-55G3PC (or 3M 10214-6212PC) connector on
the camera side. The mating cable connector is 3M 10114-3000PE with shielded housing 3M
10314-3210-00X (X indicates color preference). This connector can be purchased from Prosilica
or from http://www.digikey.com.
See Addendum for more detail.
DO NOT EXCEED 5.5V ON SIGNAL INPUTS UNLESS OTHERWISE
INDICATED. SYNC INPUT 1 CAN BE DRIVEN FROM A HIGHER VOLTAGE IF
A CURRENT LIMITING RESISTOR IS USED TO LIMIT THE CURRENT TO
LESS THAN 10 MILLIAMPS.

12V Power and Power Ground
To operate the camera 12V Power with suitable current capacity (see specifications) must be
provided on Pin 1 and the Power Ground on Pin 2.
A cable assembly providing this power can be ordered from Prosilica (Prosilica P/N 02-8007A
for North America or Prosilica P/N 02-8008A for a Universal supply).
Sync Input 1 and Sync Input 2
These input signals allow the camera to be synchronized to some external event. The camera can
be programmed to trigger on the rising edge, falling edge, both edges or level of this signal. The
camera can also be programmed to capture an image at some programmable delay time after the
trigger event.
Sync Input 1 is isolated and should be used in noisy environments to prevent false triggering due
to ground loop noise. Sync Input 2 is non-isolated and can be used when a faster trigger is
required and when environmental noise is not a problem.
Sync Output 1 and Sync Output 2
These signals only function as outputs and can be configured as follows:
Exposing Corresponds to when camera is
integrating light.
Trigger Ready Indicates when the camera will accept a
trigger signal.
Trigger Input A relay of the trigger input signal used
to “daisy chain” the trigger signal for
multiple cameras.
Readout Valid when camera is reading out data.
Imaging Valid when camera is exposing or
reading out.
Strobe Programmable pulse based on one of the
above events.
GPO User programmable binary output.
Any of the above signals can be set for active high or active low.
Sync Output 1 will require a pull up resistor of greater than 1Kohm to the user’s 5V logic supply.
Sync Output 1 is isolated and should be used in noisy environments. Sync Output 2 is non-
isolated and can be used when environmental noise is not a problem and when faster response is
required.
RS-232 RXD and RS-232 TXD
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. Note that these signals are

GB2450 User Manual 70-0046A-A

not isolated and therefore careful attention should be used when designing cabling in noisy
environments.
Isolated Ground
Isolated Ground must be connected to the user’s external circuit ground if Sync Input 1 or Sync
Output 1 is to be used.
Signal Ground
Signal Ground must be connected to the user’s external circuit ground if Sync Input 2 or Sync
Output 2 is to be used or if the RS-232 port is to be used. Note that Signal Ground is common
with Power Ground however it is good practice to provide a separate ground connection for
power and signaling when designing the cabling.
Video Iris
This signal can be used to drive the video input of a video iris lens. See Addendum.
DNC
These signals are reserved for future use and should be left disconnected.

Cleaning the Sensor
DO NOT CONTACT CLEAN SENSOR UNLESS ABSOLUTELY NECESSARY.
Identifying Debris
Debris on the image sensor or optical components will appear as a darkened area or smudge on
the image that does not move as the camera is moved. Do not confuse this with a pixel defect
which will appear as a distinct point.
Locating Debris
Before attempting to clean the image sensor, it is important to first determine that the problem is
due to debris on the sensor window. To do this you should be viewing a uniform image, such as
a piece of paper, with the camera. Debris will appear as a dark spot or dark region that does not
move as the camera is moved. To determine that the debris is not on the camera lens, rotate the
lens independent of the camera. If the spot moves as the lens moves, then the object is on the
lens -not on the image sensor- and therefore cleaning is not required. If the camera has an IR
filter, then rotate the IR filter. If the object moves then the particle is on the IR filter not the
sensor. If this is the case remove the IR filter carefully using a small flat head screw driver.
Clean both sides of the IR filter using the same techniques as explained below for the sensor
window.
DO NOT TOUCH ANY OPTICS WITH FINGERS. OIL FROM FINGERS CAN
DAMAGE FRAGILE OPTICAL COATINGS.
Cleaning with Air
If it is determined that debris is on the sensor window, then remove the camera lens, and blow
the sensor window directly with clean compressed air. If canned air is used, do not shake or tilt
the can prior to blowing the sensor. View a live image with the camera after blowing. If the
debris is still there, repeat this process. Repeat the process a number of times with increased
intensity until it is determined that the particulate cannot be dislodged. If this is the case then
proceed to the contact cleaning technique.
Contact Cleaning
Only use this method as a last resort. Use 99% laboratory quality isopropyl alcohol and clean
cotton swabs. Dampen the swab in the alcohol and gently wipe the sensor in a single stroke. Do
not reuse the same swab. Do not wipe the sensor if the sensor and swab are both dry. You must
wipe the sensor quickly after immersion in the alcohol, or glue from the swab will contaminate
the sensor window. Repeat this process until the debris is gone. If this process fails to remove
the debris, then contact Prosilica.

Adjusting the C-mount
C-M UNT RING
L CKING RING
Figure 3. Camera Front View.
THE C-MOUNT IS ADJUSTED AT THE FACTORY AND SHOULD NOT
REQUIRE ADJUSTING.
If for some reason, the C-mount requires adjustment, use the following method.
Loosen Locking Ring
Use an adjustable wrench to loosen 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. A wrench suitable for
this procedure can be provided by Prosilica (P/N 11-0048A).
Image to Infinity
Use a c-mount compatible lens that allows an infinity focus. Set the lens to infinity and image a
distant object. The distance required will depend on the lens used but typically 30 to 50 feet
should suffice. Make sure the lens is firmly threaded onto the c-mount ring. Rotate the lens and
c-mount ring until the image is focused. Carefully tighten locking ring. Recheck focus.

Camera Installation
Computer Interface
The Prosilica GB Series cameras will work with any Ethernet network card; however Prosilica
strongly recommends using Gigabit Ethernet components that support Jumbo Frames. A Jumbo
Frame is loosely defined as a frame size greater than 1500 bytes however typical Jumbo Frames
are around 9000 bytes. Frame size is the number of bytes per packet and the larger the frame
size, the less the computer CPU will be loaded due to the processing of incoming packets.
There are many Gigabit Ethernet cards available which will support Jumbo Frames. The
following examples have been verified to work well with the Prosilica cameras:
•Intel PRO/1000
•D-Link DGE-550T
•SMC EZ Card 1000
Gigabit Ethernet cards supporting this feature can also be purchased with the camera (Prosilica
P/N 02-3002A).

Installing GigE Viewer for Testing
oThe latest Viewer software can be downloaded from http://www.prosilica.com/support.htm.
oRun the GigE Viewer Installer.exe. This will install the Prosilica Digital Camera drivers as
well as the Prosilica GigE Viewer application program.
oPlug in the Prosilica camera via the Gigabit Ethernet port. Plug in the power connection.
Verify that the Status LED 2 is a solid green. Run the Prosilica GigE Viewer Application. It
will take a few seconds for the camera to be recognized. If the camera does not appear in the
Viewer list after approximately 10 seconds then try disconnecting and reconnecting the
power. If it still does not appear restart the viewer. If it still does not appear, see the Trouble
Shooting section of this document.
oSee Figure 7. Select the wrench icon to change camera settings. Change the PacketSize to a
value of 1500. Select the eye icon to image. The camera should now be imaging. If the
camera is not imaging, see the Trouble Shooting section of this document. Note that the
PacketSize can be set to 8228 if the network card has been optimized to support jumbo
frames.
oSee the System Optimization Section to maximize the performance of your system.
