    1. Gigabit Ethernet Interface

    Line scan cameras of the VKOC-XL series use the Gigabit Ethernet communication protocol and are 100% compliant with the GigE VisionTM specification and the GenCamTM standard.

    GigE Vision allows for fast image transfer using low cost standard cables up to distances of 100 m. With GigE Vision, hardware and software from different vendors can interoperate seamlessly via the GigE connections. The camera is connected to a computer either via the GigE socket directly or through a Gigabit Ethernet switch.

    The line scan cameras of the VKOC-XL series implement a superset of the GenCam specification which defines the device capabilities. This XML device description file employs the syntax defined by the GenApi module of the GenCamTM specification.

    The GenCamTM standard provides a generic programming interface for all kinds of cameras and, no matter what features they implement, the application programming interface (API) always remains the same. The GenCamTM standard consists of multiple modules relevant to the main tasks to be solved:

    GenApi: for configuring the camera Standard Feature Naming Convention (SFNC): recommended

    names and types for common features GenTL: transport layer interface, for grabbing images

    For more information on the GigE VisionTM specification, see:

    3. Hardware and Software Requirements


    To optimize the Network Adapter, open the Device Manager and go to Advanced Properties of the Adapter

    Recommended optimization values: Receive Descriptors/Empfangsdescriptors = 2048 Interrupt Moderation Rate/Interrupt-Drosselungsrate=extreme Jumbo Frames = 9014 Byte

    eBUS Driver Installation Tool allows choice of the best driver according to needs (also provided with SkGEVTool).

    With the installed eBus driver, the additional optimization of the network adapter is not necessary

    Trouble-shooting:If the camera cannot connect properly with the NIC or has acquisition timeout errors, there may be a conflict between the eBus Optimal driver and a third party filter driver. In this case, install the eBus Universal Driver or install the driver supplied by the manufacturer and use the filter driver of the third party software.

    PC: Intel Pentium 4 or AMD equivalent RAM min. 1 GB, depending on size of acquired images High-performance video card using either an AGP bus or

    PCIe bus Operating System: Windows XP, Windows Vista, Windows 7

    (32-bit and 64-bit) are supported

    Network Adapters: Any Gigabit Ethernet network adapter as a card or on the

    motherboard is suitable. For the best performance, a NIC with Intel PRO/1000 chip is recommended.

    PCIe adapters outperform PCI adapters. Network adapters that support Jumbo Frames outperform

    adapters with fixed packet-size frames.

    Optimizing the Network Adapter (not eBus Optimal driver)Most Gigabit network interface controllers allow the user to modify their parameters, such as Adapter Buffers and Jumbo Frames. These should be optimized during installation in the Advanced Properties of the Network Adapter.

    The line scan cameras of the VKOC-XL series work with any software that is GenCamTM compliant and that supports GigE Vision cameras. Most software products provide their own network filter driver for a better performance and, where available, this filter driver should be installed.

    If no special software is available then the recommended software package is the latest eBUS SDK from Pleora:

    The software package contains a SDK and two kinds of eBus drivers (instead of a filter driver).

    1. The eBUS Universal Driver ideal for most real-time vision applications. It runs on almost any vendor NIC, handles all IP transport protocols including ordinary network traffic and GigE Vision transport protocols and has less CPU usage than a filter driver.

    2. The eBUS Optimal Driver ideal for applications with a very heavy processing overhead. It runs on the Intel PRO/1000 family of NICs, handles all IP transport protocols including ordinary network traffic and GigE Vision transport protocols and exhibits the lowest CPU load in the industry.

    To Set the NIC IP address:

    Start > Control Panel > Network Connections.

    Right-click Local Area Connection and select Properties.

    The Local Area Connection Properties dialog appears.

    Select Internet Protocol (TCP/IP) and click Properties. The

    Internet Protocol (TCP/IP) Properties dialog appears.

    Enable "Use the following IP address" and enter the following settings: IP address: Subnet mask: Default gateway: leave blank

    Ensure these do not conflict with an existing IP address on another NIC. For multiple dedicated connections on the same host PC, increment the third IP address by one for each NIC (i.e. 36, 37, etc., subnet - class C).

    Click OK to close the Internet Protocol (TCP/IP) Properties dialog.

    Click Close to close the Local Area Connection Properties dialog.

    Your NIC is now configured for a dedicated connection.

    The GigE Vision camera has an enforced static IP address. The NIC IP address must be part of the same subnet otherwise the camera is not accessible.

    An example of a Persistent IP address assigned to a class B network is:
