Genie Nano IP Configuration Sequence
The Genie Nano 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, Nano 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)
The factory defaults for Nano is Persistent IP disabled and DHCP enabled with LLA always enabled
as per the GigE Vision specification. For additional information see Nano IP Configuration Mode
Details.
Supported Network Configurations
The Genie Nano 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 Genie Nano issues a DHCP request
for an IP address. The DHCP server then provides the Nano 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 Genie Nano
(refer to the Teledyne DALSA Network Imaging user’s manual).
The LLA method, if used, automatically assigns the Nano 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.
