is carried out via the menu item Extras
DHCP (Dynamic Host Configuration Protocol) is used so that the paperless
recorder can automatically receive an IP address and other communication
parameters from a DHCP server.
On
The other communication parameters that the paperless recorder usually
receives from the DHCP server include the subnet mask, gateway address,
and the lease time.
When the lease time (user time) has expired, the IP address loses its validity. In
order that the paperless recorder may always have a valid IP address, it sends
a query to its DHCP server whether the address is still valid when 50 of the
lease time has expired. If the DHCP server is not available, the recorder
repeats the query until 87.5% of the lease time has expired. After that, the
recorder sends the query not only to the DHCP server, but to the entire
network. If the lease time expires without the IP address being confirmed, the
recorder declares the address as invalid and is no longer accessible in the
network.
