5.4. IPConguration
5.4.1. PersistentIP
A persistent IP adress is assigned permanently. Its validity is unlimited.
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 camera on the y. 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�
5.4.2. DHCP(DynamicHostConguration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 nd 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.
