Calibir IP Configuration Sequence
The Calibir GigE IP (Internet Protocol) Configuration sequence to assign an IP address is executed
automatically on camera power-up or when connected to a network. As a GigE Vision compliant
device, Calibir 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 Teledyne DALSA Smart DHCP server)
•
Link-Local Address (always enabled as default)
Supported Network Configurations
The Calibir obtains an IP address using the Link Local Address (LLA) or DHCP, by default. If
required, a persistent IP address can be assigned (refer to the Network Imaging manual).
Preferably, a DHCP server is present on the network, where the Calibir issues a DHCP request for
an IP address. The DHCP server then provides the Calibir an IP address. The Teledyne DALSA
Network Configuration tool, installed with the Sapera Teledyne DALSA Network Imaging
Package, provides a DHCP server which is easily enabled on the NIC used with the Calibir (refer to
the Teledyne DALSA Network Imaging user's manual).
The LLA method, if used, automatically assigns the Calibir with a randomly chosen address on the
169.254.xxx.xxx subnet. After an address is chosen, the link-local process sends an 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 the LLA mode is
unable to forward packets across routers.
