DHCP Dynamic Host Protocol Server -
enables you to communicate
with a Daniel meter that is not
connected to a network.
When the CPU Module switch is
in the ON position, the meter is
enabled to act as a DHCP server
for a single DHCP client
connected to the Ethernet port
using a crossover cable. This
should be used for peer to peer
connections only.
When the connection is made,
select to use the Meter Name in
the meter instead of the Meter
Directory Name in order to
keep all log files and
configurations separate from
each meter.
