DHCP (Dynamic Host Configuration Protocol)
• This Genie IP configuration mode requires a DHCP server to allocate an IP address dynamically. The Genie
must be configured to have DHCP enabled. This is the factory default settings.
• The DHCP server is part of a managed network. Windows XP itself does not provide a DHCP server function.
A dedicated DHCP server is required. Open-source DHCP server software can be found on the Internet, but
they might not provide the same level of functionality as commercial-grade DHCP servers.
• A DHCP server is recommended where there are multiple NIC ports with multiple GigE Vision devices
attached. Each NIC ports must use a different subnet to avoid IP address conflicts (see "
GigE Server Warning
Example 1a: IP error with multiple NICs" on page 103).
• Under Windows, a NIC is configured in DHCP mode by default. If no DHCP server is present on a given
subnet, Windows will revert to LLA as explained in the section above.
• Ensure that a different subnet is assigned to each NIC on the network. Typical ranges are 192.200.x.x or
10.10.x.x for internal networks.
Persistent IP
• This protocol is only suggested if the user fully controls the assignment of IP addresses on the network and a
GigE Vision camera is connected beyond routers.
• The GigE Vision camera is forced a static IP address. The NIC IP address must use the same subnet otherwise
the camera is not accessible.
• If the Genie camera is connected to a network with a different subnet, it cannot be accessed.
• The DALSA network configuration tool is used to set a persistent IP address.
• An example of a Persistent IP address assignment:
• Persistent IP = 192.200.1.1
• Subnet Mask = 255.255.0.0
• Default Gateway = 0.0.0.0
• Warning: an incorrect IP address assignment might make it impossible to connect to the camera. In such a case
the DALSA network configuration tool includes a function to recover a Genie camera with an unknown
persistent IP and set the Genie to the factory default setting, i.e. DHCP/LLA mode. The Genie MAC address
must be known to use this function. See "
Recovering a Camera with an Unknown Persistent IP" on page 82 and
"
GigE Server Warning Example 2: Subnet Mask or IP error" on page 105.
• For GigE Vision applications the FORCEIP command is used to force a new persistent IP or to change the IP
configuration protocol. The Genie MAC address must be known to use the FORCEIP command.
