Linea2 5GigE IP Configuration Sequence
The IP (Internet Protocol) Configuration sequence to assign an IP address is executed automatically
on camera power-up or when a connection is established to a network. As a GigE Vision compliant
device, Linea2 5GigE attempts to assign an IP address as follows.
For any GigE Vision device, the IP configuration protocol sequence is:
•
Persistent IP (if enabled)
•
DHCP (if a DHCP server is present such as the Sapera DHCP server)
•
Link-Local Address (always enabled)
The factory defaults for Linea2 5GigE is Persistent IP disabled and DHCP enabled with LLA always
enabled as per the GigE Vision specification.
Supported Network Configurations
The Linea2 5GigE obtains an IP address using the Link Local Address (LLA) or DHCP, by default. A
LLA IP address is obtained typically in a few seconds with Microsoft Windows. If required, a
persistent IP address can be assigned (see the Running the Network Configuration Tool section).
Preferably, a DHCP server is present on the network, where the Linea2 5GigE issues a DHCP
request for an IP address. The DHCP server then provides the IP address. The Teledyne DALSA
Network Configuration tool, installed with the Teledyne DALSA Network Imaging Package, provides
a DHCP server which is easily enabled on the NIC used with the Linea2 5GigE (Refer to Teledyne
DALSA
’s Sapera LT Getting Started Manual for GigE Vision Cameras
& 3D Sensors).
The LLA method, if used, automatically assigns the camera with a randomly chosen address on the
169.254.xxx.xxx subnet. After an address is chosen, the LLA process sends an Address Resolution
Protocol (ARP) query with that IP onto the network to see if it is already in use. If there is no
response, the IP is assigned to the device, otherwise another IP is selected, and the ARP is
repeated. Note that LLA is unable to forward packets across routers.
