Linea2 5GigE Series Camera
DHCP (Dynamic Host Configuration Protocol)
•
This IP configuration mode requires a DHCP server to allocate an IP address dynamically over
the range of some defined subnet. The Linea2 5GigE camera must be configured to have DHCP
enabled. This is the factory default setting.
•
The DHCP server is part of a managed network. Windows itself does not provide a DHCP server
function therefore a dedicated DHCP server is required. The Teledyne DALSA
’s
Network
Configuration Tool can configure the Teledyne DALSA DHCP server on the NIC used for the GigE
Vision network.
•
Teledyne DALSA DHCP server is recommended where there are multiple NIC ports with multiple
GigE Vision devices attached. Each NIC port must use a different subnet to avoid IP address
conflicts. Persistent IP assignment is required if there is no DHCP server for any additional
subnet.
•
Windows configures a NIC in DHCP mode by default. If no DHCP server is present on the
subnet, Windows reverts to LLA mode.
•
Ensure a different subnet is assigned to each NIC on the network. This will automatically be
managed when the Teledyne DALSA DHCP server is enabled on one or all subnets used for GigE
Vision devices. The graphic below illustrates a system with one NIC having the Teledyne DALSA
DHCP server enabled.
