The General Purpose I/O port uses a Hirose HR10A-10R-12PB connector on the camera side.

The mating cable connector is Hirose HR10A-10P-12S. 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 2 and the Power Ground on Pin 1.

A cable assembly providing this power can be ordered from Prosilica (Prosilica P/N 02-8003A for North America or Prosilica P/N 02-8004A 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

Trigger Ready

Trigger Input

Readout

Imaging

Corresponds to when camera is integrating light.

Indicates when the camera will accept a trigger signal.

A relay of the trigger input signal used to “daisy chain” the trigger signal for multiple cameras.

Valid when camera is reading out data.

Valid when camera is exposing or reading out.

Strobe Programmable pulse based on one of the above events.

User programmable binary output. GPO

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 nonisolated 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.

Video Iris

This signal can be used to drive the video input of a video iris lens. See Addendum.

Cleaning the Sensor

70-0018A-D

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

70-0018A-D

LOCKING RING

C-MOUNT RING

Figure 4. 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

70-0018A-D

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).

Is the camera getting power?

The right LED is the camera power indicator. If unlit, check the power adaptor. If possible, swap with one that is known to work. If using a custom power adaptor, be sure the adaptor and wire gauge is rated to at least 500 mA. If the right LED still does not light up, contact Prosilica support.

Is the camera powered, but not detected in SampleViewer?

Damaged or poor quality Ethernet cabling can result in no cameras found, dropped packets, decreased bandwidth, and other problems. Use Cat5e or better cabling known to work.

Configure your NIC as outlined in “Gigabit Ethernet Setup For Windows”. It should have an IP address of 169.254.x.x, Subnet Mask: 255.255.0.0. This is the AutoIP address range. If your NIC has no access to a DHCP server, the camera will still be auto assigned an IP address. There should be no gateway on your NIC.

Connect a single camera directly to your NIC, no hub/switch, and run the prosilica IP

Configuration utility (Start>Programs>Prosilica>GigEIPConfig or C:\Program

Files\Prosilica\GigEViewer\ipconfig.exe). You may need to wait up to 30 sec for camera to appear.

A camera in DHCP (AutoIP fallback) mode.

The following example is not on the same Subnet: NIC IP 169.250.23.2 Subnet Mask:

255.255.255.0, CamIP 169.254.13.0 Subnet Mask: 255.255.0.0. This can happen if you use a non

AutoIP range on your NIC and it doesn’t have access to a DHCP server. Either change your NIC

IP to be in the AutoIP range, or fix the camera IP address to be on the same subnet as your NIC.

•

Camera is not listed, or flashing “Camera Unavailable”: There may be multiple NICs on your system set to the same subnet. The camera can not know which card to resolve to. Change the IP address of your NIC.

If you are still having problems, type: ipconfig /all in a windows command prompt, and send a screenshot to [email protected].

All stats 0 while streaming. Firewall likely blocking traffic

•

All stats 0. Likely a firewall is blocking incoming traffic. Disable your firewall. Check your camera trigger settings. Many camera trigger modes require a software or hardware trigger event to capture frames.

•

Packets are incoming, but all dropping. Be sure you have JumboFrames enabled on your

NIC. Otherwise, decrease your PacketSize setting to 1500.

•

All packets completing as normal, but black image. Check ExposureValue,

ExposureMode, and be sure your scene is suitably lit.

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. 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.

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.
