5.4. IP Configuration

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:

0.0.0.0 – 127.255.255.255

128.0.0.0 – 191.255.255.255

192.0.0.0 – 223.255.255.255

These combinations are not checked by Baumer-GAPI, Baumer-GAPI

Viewer or camera 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�

5.4.2. 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

Information on server

MAC address

offered IP address

IP adress

subnet mask

duration of the lease

Subnet mask:

255�0�0�0

255�255�0�0

255�255�255�0

Internet Protocol:

On Baumer cameras IP v4

is employed.
