These large packets, also known as Jumbo packets, allow the camera to more efficiently transfer data across the network. However, the GigE Vision standard allows packet sizes of up to 9014 bytes.

Typically, network drivers will split any data larger than 1500 bytes into multiple packets. Windows displays a warning when camera is directly connected Jumbo Packets Note: that the delay only applies to Windows XP and 2000, not the Windows Vista Operating System.įigure 1. The Windows operating system may display a warning that the network card has only limited operation.
If the camera is connected directly to the computer (using either a regular or cross-over cable), you will need to wait about a minute for the camera to timeout on the DHCP request and use LLA. If you connect the camera to a Gigabit Ethernet network with a DHCP server, the camera is automatically detected. As discussed in Part I, GigE Vision cameras can obtain an IP address from a DHCP server or select one for itself using Link Local Addressing (LLA). Once you have the hardware and software installed correctly, you must configure the network as well.
NI VISION ACQUISITION SOFTWARE INSTALL
Vision Acquisition Software: You will need Vision Acquisition Software 8.2.1 or higher, which will install NI-IMAQdx 3.0 or higher.It is highly recommended that you use a Gigabit Ethernet Network Interface Controller (NIC). Gigabit Ethernet port: While it is possible to acquire images with Ethernet and Fast Ethernet ports, which support 10 MB/s and 100 MB/s respectively, this will only work at very slow frame rates and small resolutions.You should find the GigE Vision logo in the camera's user manual or marketing literature. If you have a camera that has a Gigabit Ethernet port but is not GigE Vision compliant, you cannot acquire images using Vision Acquisition Software.
GigE Vision camera: The camera must be GigE Vision standard compliant.In order to acquire images from a GigE Vision camera, you need to first make sure that you have all the correct hardware and software.
