GigE Network Adapter Overview
If the computer to be used with the Linea GigE camera does not have a Gigabit network adapter or
second built in Gigabit NIC, a Gigabit Network Interface adapter card (NIC) needs to be installed.
Typically under Windows, the Gigabit NIC is recognized automatically when Windows boots.
With any high performance Gigabit NIC adapter, review the NIC documentation concerning any
special driver required for your specific operating system. When adding a NIC adapter to a
computer, Teledyne DALSA engineering has seen cases where a PCI Express bus Gigabit NIC has
better overall performance than the same NIC hardware in PCI bus format.
PAUSE Frame Support
The Linea GigE supports the Gigabit Ethernet PAUSE Frame feature as per IEEE 802.3x. PAUSE
Frame is the Ethernet flow control mechanism that temporarily stops data transmission on the
network. The PAUSE Frame feature can help a NIC that doesn’t have enough buffering to handle
full-speed reception. This requires that the flow control option in the NIC property settings and the
Ethernet switch settings must be enabled.
Note that this problem is not as common with advances in computer bus speeds and memory sizes.
PAUSE Frame support is typically required to manage network traffic within an Ethernet switch
when multiple cameras are simultaneously used. Using PAUSE Frame will require the user to test
various values of Jumbo Frames, to determine the best data throughput. Therefore the downside to
managed network traffic is that the Pause Frame control will reduce the absolute maximum
transfer bandwidth possible on the network.
Connect the Linea GigE Camera
Connecting a Linea GigE to a network system is independent of whether the Teledyne DALSA
Sapera LT package or a third party GigE Vision development package is used.
• Before connecting power to the camera, test all power supplies. Power supplies must meet the
requirements defined in section "Input Signals Electrical " on page 105. Apply power to the
camera.
•
Connect Linea GigE to the host computer GigE network adapter or to the Ethernet switch via a
CAT5e or CAT6 Ethernet cable. Note: cable should not be less than 1 meter (3 feet) long or
more than 100 meters (328 feet) long.
• Once communication with the host computer is started the automatic IP configuration sequence
will assign an LLA IP address as described in section "Linea GigE IP Configuration Sequence" on
page 16, or a DHCP IP address if a DHCP server is present on your network.
•
Check the diagnostic LED which will be initially red then switch to flashing blue while waiting for
IP configuration. See "Camera Status LED " on page 15 for Linea GigE LED display descriptions.
