A. WRITE PROT. switch
B. DHCP switch
C. Port A (override)
The DHCP switch enables or disables the DHCP server for Ethernet communication.
The WRITE PROT. switch enables or disables "write protection" of the meter
configuration.
Set the DHCP switch to the ON position to enable Ethernet communication via the
DHCP server. Set the WRITE PROT. switch to the OFF position to allow configuration
parameters to be written to the meter. Only enable the DHCP server if the meter
is not connected to a network that may have a DHCP server already running. The
DHCP server is designed for use when a PC connects directly to the meter and
requires the meter to assign the PC an IP address.
