Function
• Write-protect mode - with switch
in the ON position (default
setting) protects configuration
and firmware overwrites.
• To write configuration changes or
download firmware to the meter
change the switch to the OFF
position
• 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.
• PORT A override - RS-232 serves as
an override during meter
commissioning to establish
communications and in the event
the user cannot communicate
with the meter due to an
inadvertent communication
configuration change. The
override period is for two minutes.
