12.8 IP Configuration
12.8.1 Persistent IP
A persistent IP adress is assigned permanently
. Its validity is unlimited.
Notice
Please ensure a valid combination of
IP address and subnet mask.
IP range:
Subnet mask:
0.0.0.0 – 127.255.255.255
255.0.0.0
128.0.0.0 – 191.255.255.255
255.255.0.0
192.0.0.0 – 223.255.255.255
255.255.255.0
These combinations are not checked by
Baumer-GAPI, Baumer-GAPI Viewer or cam
-
era on the fly. This check is performed when restarting the camera, in case of an invalid
IP - subnet combination the camera will start in LLA mode.
* This feature is disabled by default.
12.8.2 DHCP (Dynamic Host Configuration Protocol)
The DHCP automates the assignment of network parameters such as IP addresses, sub-
net masks and gateways. This process takes up to 12 sec.
Once the device (client) is connected to a
DHCP-enabled network, four steps are processed:
▪
DHCP Discovery
In order to find a DHCP server, the client sends a so called DHCPDISCOVER broad
-
cast to the network.
▪
DHCP Offer
After reception of this broadcast, the
DHCP server will answer the request by a
unicast, known as DHCPOFFER. This message contains several items of information,
such as:
Information for the client
MAC address
offered IP address
Information on server
IP adress
subnet mask
duration of the lease
Internet Protocol:
On Baumer cameras IP v4
is employed.
