Linea Lite GigE Series Camera
IP Configuration Mode Details
The following descriptions provide more information on the IP configuration modes supported by
Linea Lite GigE. In general, automatic IP configuration assignment (LLA/DHCP) is sufficient for
most Linea Lite installations.
Please refer to the
Teledyne DALSA Network Imaging Package manual
for information on the
Teledyne DALSA Network Configuration tool and network optimization for GigE Vision cameras and
devices.
In addition, refer to the manual (
Sapera Getting Started Manual For GigE Vision Cameras
)
installed with the Sapera LT package, for an overview of using GigE Vison cameras.
Link-Local Address (LLA)
•
LLA is also known as Auto-IP. It is used for unmanaged networks including direct connections
from a GigE Vision device to a dedicated NIC.
•
A subnet configured with LLA cannot send packets across routers but only via Ethernet
switches.
•
LLA is the recommended scheme when only one NIC is connected to GigE cameras. LLA is fully
automatic requiring no user input.
Note
: Ensure only one NIC is using LLA on your PC, otherwise IP conflicts will
result.
•
The NIC will automatically assign a random IP address within the 169.254.x.x subnet. The LLA
protocol ensures there are no conflicts with other devices through an arbitration scheme.
•
The Windows NIC configuration must be set to DHCP (the typical default case) and no DHCP
server must be present on the network. Otherwise, an IP address gets assigned by the DHCP
server. Windows will turn to LLA when no DHCP server answers requests coming from the NIC.
•
Windows and Linea Lite GigE are still running the DHCP process in the background. If a DHCP
server becomes available on the network, the NIC will get a DHCP assigned IP address for the
connected device but connections on the LLA IP address will be lost. The Teledyne DALSA
Network Configuration Tool can enable the Teledyne DALSA DHCP server on the NIC used for
the GigE Vision network.
Important
: If the host system has multiple NIC devices configured with LLA,
then the communication stack cannot accurately resolve which NIC to forward an
IP packet on the 169.254 segment. Limit the number of NIC configured using
LLA to one interface. It is preferable that the Teledyne DALSA DHCP server is
used instead of LLA mode (see next section).
•
Use the Teledyne DALSA Network Configuration Tool to change the Linea Lite GigE from the
default DHCP/LLA mode to Persistent IP mode when required, such as when there are multiple
NIC devices with Linea Lite GigE connected to each. Note that Teledyne DALSA recommends
DHCP/LLA as the mode of operation where a switch is used to connect multiple devices.
