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.
70-0032A-A
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
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.

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.
70-0032A-A
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.

Camera Installation
Computer Interface
The Prosilica GC 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).

Trouble Shooting
Check the Basics
o Is power available? Check the status LED 2. If the LED is off, the camera is not getting
power. Verify the connections and cabling.
o Is the LED 2 flashing once per second? This occurs if the firmware is corrupt because a
firmware update was interrupted. If this is the case, run the firmware updater again, carefully
following the instructions. If the problem persists, contact Prosilica.
o Is the LED flashing 3 times once per second? This indicates a fault with the camera. If this
problem persists, please contact Prosilica.
Test the Camera with the Prosilica Viewer
Download and install the Prosilica Viewer (from http://www.prosilica.com/support.htm).
o Can the Viewer find the camera? Is the camera listed in the main application window or is
the list empty? If the camera is not listed, proceed to Driver Issues.
o Is the image black? If so, check the optics. Check that lens iris is fully open. Check
exposure time - in room lighting, an exposure time of 30ms should be adequate to see an
image. If image is still black, contact Prosilica.
70-0032A-A
o Is the image white?
• If the camera is in external trigger mode, a snapshot will not complete until a
hardware trigger is received.
• Image data may fail to arrive at the computer if there is a problem with the driver. If
you suspect a driver problem, proceed to Driver Issues.
o Is the image white, but the camera is not waiting for an external trigger? Do you have a lens?
Check your exposure time, offset, and gain controls.
o Does the image occasionally freeze? Test the camera with an alternate Ethernet cable and
card. If the problem persists, contact Prosilica.
• An intermittent connection will result in the loss of image data, but you likely will not
notice a problem when using the camera controls.
Driver Issues
TBD.
Camera will not trigger
Check cabling and connections. Verify that external trigger circuit is providing a compatible
trigger signal. Use the Prosilica Viewer program in trigger mode to eliminate possible software
issues.

Notes on Triggering
Definitions
o User Trigger is the trigger signal applied by the user.
o Logic Trigger is the trigger signal seen by the camera internal logic.
o Tpd is the propagation delay between the User Trigger and the Logic Trigger.
o Exposure is high when the camera image sensor is integrating light.
o Readout is high when the camera image sensor is reading out data.
o Trigger Latency is the time delay between the User Trigger and the start of Exposure.
o Trigger Jitter is the error in the Trigger Latency time.
o Trigger Ready indicates to the user that the camera will accept the next trigger.
o Registered Exposure Time is the Exposure Time value currently stored in the camera
memory.
o Expose Start Delay is the delay time from the start of Exposure to valid Trigger Ready. It is
the Registered Exposure Time subtracted from the Readout time and indicates when the next
Exposure cycle can begin such that the Exposure will end after the current Readout.
70-0032A-A
o Interline Time is the time between sensor row readout cycles.
o Imaging is high when the camera image sensor is either exposing and/or reading out data.
o Idle is high if the camera image sensor is not exposing and/or reading out data.
Rules
o The User Trigger pulse width should be at least three times the width of the Trigger Latency
as indicated in the Specifications section of this document.
o The end of Exposure will always trigger the next Readout.
o The end of Exposure must always end after the current Readout.
o The start of Exposure must always correspond with the Interline Time if Readout is true.
o Expose Start Delay equals the Readout time minus the Registered Exposure Time.
Triggering during the Idle State
o 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.
o In this case, Trigger Latency and Trigger Jitter are as indicated in the Specifications section.
Prosilica Inc.
23
GC750 User Manual
Triggering during the Readout State
o For applications requiring the fastest triggering cycle time whereby the camera image sensor
is exposing and reading out simultaneously, then the User Trigger signal should be applied as
soon as a valid Trigger Ready is detected.
o In this case, Trigger Latency and Trigger Jitter can be up to 1 line time since Exposure must
always begin on an Interline boundary.
