not already in use on your network. You may also want to check with your network
administrator to make sure the IP address you plan on using is available to use on
your network. After entering the Network addresses exit out of the menu, and when
prompted to save the new configuration settings, press the button directly under the
SAVE prompt identified as “Y” (Yes). Reboot the meter for the configuration changes
to take effect.
Enter the IP Address for the meter through a standard web browser:
Before entering an IP address with this method make sure the current IP address and
the new IP address to be assigned to the meter will not cause IP address conflicts on
your local network. To connect to the web server enter the meter’s current IP Address
in your web browser’s address bar. When the web server screen appears click on the
“Settings” tab. Type the new Network settings (IP address, Subnet mask, Gateway) in
the appropriate fields and click the “Apply” button to send the new network settings to
the meter. Reboot the meter for the configuration change to take effect.
The M66x uses the following port numbers for each type of protocol:

Determining the IP Address if unknown:
Although the IP address can be obtained via the display, for the M661 which does not
have a display, Bitronics has created a utility program to request the IP address for a
specific MAC address on an Ethernet network. This program can be used with the
M660 as well. The program is available on the company website
(
http://www.novatechweb.com/downloads/inarp/).
The program uses the Inverse Address Recognition Protocol to perform the lookup
and thus is called inarp. The InARP protocol definition can be found at
www.apps.ietf.org/rfc/rfc2390.html. The inarp utility can also scan an Ethernet
network for a range of MAC addresses, printing the IP address for any devices which
respond.
The general form of inarp is defined below, followed by some usage examples.
inarp usage:
inarp [-i <if_ipaddr>] [-n <cnt>] [-p <ms>] [-v] <mac-spec>
where
<if_ipaddr> := interface ip address (default is 1st Ethernet interface)
<cnt> := count of addresses to poll (default 1)
