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.

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.
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.
Adjusting the C-mount 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 AVT (P/N 11-0048A).
Camera Installation Computer Interface The Prosilica GC cameras will work with any Ethernet network card; however AVT 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.
Gigabit Ethernet Setup for Windows o Install network card in computer. o Boot the PC and cancel the “Found new Hardware Wizard” window that may appear when Windows detects the new card. o Install the driver that came with the network card. o Once the driver is installed, open the Network Connections Dialog as follows: From the Windows desktop select start, then select Control Panel, then double click on the Network Connections icon.
o Select the Internet Protocol (TCP/IP) check box and then select Properties. See Figure 6. Network card TCP/IP address.. Select the Use the following IP address and enter an IP address of 169. 254. x. y, where x and y can be any number. Press the TAB key after entering the IP address and the subnet mask will automatically be entered. The subnet mask is 255. 255. 0. 0. Click OK to save changes.
Figure 7. Turn off Firewall. o Return to the Gige Local Properties window as in Figure 5. Select the Advanced tab as in Figure 7 and disable the Firewall for this device. Click OK to save changes. Gigabit Ethernet Cabling All Gigabit Ethernet cabling and connectors should be CAT5E or CAT6 compatible. Cable lengths must not exceed 100 meters. Power Connection The camera requires a 12V DC power supply that can source a minimum of 500 mA of current.
Installing GigE Viewer for Testing o The latest Viewer software can be downloaded from http://www.alliedvisiontec.com/us/support.html. o Run the GigE Viewer Installer.exe. This will install the Digital Camera drivers as well as the GigE Viewer application program. o Plug in the Prosilica GC camera via the Gigabit Ethernet port. Plug in the power connection. Verify that the Status LED 2 is a solid green. Run the GigE Viewer Application. It will take a few seconds for the camera to be recognized.
System Optimization o Open the Network Connections Dialog as follows: From the Windows desktop select start, then select Control Panel, then double click on the Network Connections icon. Double click the relevant network card listed or right-click the relevant network card and select Properties. This will open the properties window for your network card. See Figure 9. Figure 9. Network card main properties window. o From the Properties window select Configure then select the Advanced tab. See Figure 10.
Figure 10. Network card advanced settings. o Set Maximum Frame Size or Jumbo Frames to the maximum possible value. A typical value is 9000. If the list contains a property called Receive Descriptors, then change this value to its maximum value. Select OK to save properties. o From the main properties dialog as in Figure 9, make sure that only the Internet Protocol (TCP/IP) check box is selected then click OK. The card is now optimized for use with the Prosilica GC camera.
Trouble Shooting 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 AVT support.
• 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 support@alliedvisiontec.com.
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.

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.
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.
