Gev Supported Option

GevSupportedOption

Returns TRUE if the selected GEV option is

supported. (RO)

1.00

Invisible

LLA Supported

GevSupportedIPConfigurationLLA

Indicates if LLA (Auto-IP) is supported by

the selected interface. The LLA method

automatically assigns the camera 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 LLA is unable

to forward packets across routers. LLA is

the recommended scheme when only one

NIC is connected to GigE cameras; ensure

only one NIC is using LLA on your PC,

otherwise IP conflicts will result. (RO)

1.00

Invisible

DHCP Supported

GevSupportedIPConfigurationDHCP

Indicates if DHCP is supported by the

selected interface. This IP configuration

mode requires a DHCP server to allocate

an IP address dynamically over the range

of some defined subnet. The camera must

be configured to have DHCP enabled. This

is the factory default settings. 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 DALSA

Network Configuration Tool can be

configured as a DHCP server on the NIC

used for the GigE Vision network. (RO)

1.00

Invisible

Persistent IP Supported

GevSupportedIPConfigurationPersistentIP Indicates if Persistent IP is supported by

the selected interface. 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 camera is connected to a

different subnet, it cannot be accessed.
