20 • Quick Start Guide Calibir 640 GigE IR Camera User's ManualCalibir IP Configuration SequenceThe Calibir GigE IP (Internet Protocol) Configuration sequence to assign an IP address is executedautomatically on camera power-up or when connected to a network. As a GigE Vision compliantdevice, 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 ConfigurationsThe Calibir obtains an IP address using the Link Local Address (LLA) or DHCP, by default. Ifrequired, 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 foran IP address. The DHCP server then provides the Calibir an IP address. The Teledyne DALSANetwork Configuration tool, installed with the Sapera Teledyne DALSA Network ImagingPackage, provides a DHCP server which is easily enabled on the NIC used with the Calibir (refer tothe Teledyne DALSA Network Imaging user's manual).The LLA method, if used, automatically assigns the Calibir with a randomly chosen address on the169.254.xxx.xxx subnet. After an address is chosen, the link-local process sends an ARP query withthat IP onto the network to see if it is already in use. If there is no response, the IP is assigned tothe device, otherwise another IP is selected, and the ARP is repeated. Note that the LLA mode isunable to forward packets across routers.
