The Ethernet Converter Manager will search for all
Buffalo Ethernet Converters on your network. The
process usually takes less than one minute. Once
completed, the Search Results window will appear.
Search Results will list all Buffalo Ethernet Converters
on the network. If there is more than one Ethernet
Converter in the list, select the one you would like to
configure. Press the IP Settings button to continue
configuration.
The IP Address Setup window will open. Check the
box next to Use DHCP and press the OK button. The
Ethernet Converter will reboot; this process may take
as long as a minute. The Ethernet Converter Manager
will then re-scan the network for Ethernet Converters.
NOTE: If you want to give your Ethernet Converter
a static IP address, than you can skip checking Use
DHCP and enter your own IP Address and Subnet
mask in the cooresponding fields. If using a static IP
address, it is recommended to pick one inside your
existing network's subnet.
