A68/A38 Ip Configuration Sequence - Teledyne FLIR A68 Series User Manual

A68/A38 IP Configuration Sequence

The A68/A38 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, A68/A38 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 A68/A38 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 A68/A38 issues a
DHCP request for an IP address. The DHCP server then provides the A68/A38 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 A68/A38 (refer to the Teledyne DALSA
Network Imaging user's manual).
The LLA method, if used, automatically assigns the A68/A38 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.
