1. METRUM UTILIWISE® ENDPOINT OVERVIEW
Metrum Utiliwise® Endpoints are comprised of a Metrum Endpoint Communications Module
(ECM) integrated with one of the supported electric meter platforms shown in Figure 1 below.
Metrum also has an external ECM also shown in Figure 1 which enables wireless
communications with distribution assets such as breakers, regulators, capacitor banks, or any
device equipped with communication outputs. A detailed description of Metrum’s External
ECM is in Appendix 1.
Elster A3 Itron Sentinel Landis+Gyr S4
Landis+Gyr Focus Itron Centron II Metrum External ECM
FIGURE 1 METRUM SUPPORTED ECM METER PLATFORMS
Figure 1c

The ECM enables two-way, wireless communications between the meter and the utility
interface over the public network carriers such as Sprint, Verizon, AT&T, or Metrum Wireless
which is an aggregation of several public carriers. The ECM’s are Internet Protocol (IP)
devices using pass-through communications enabling Head-End software like MV-90 to
retrieve and communicate across the public networks any registers, billing determinants or the
contents of any ANSI table supported by the meter. Reading frequency and data retrieved is
completely configurable and supports up to 4 sec interval communications between the Head-
End and Endpoint. All ECM’s can operate in multiple modes and support inbound and
outbound TCP/IP and UDP communications, real-time communications, remote mode
configuration, firmware upgrades, dynamic carrier selection, signal quality monitoring, remote
diagnostics, self-registration, and pass-through communications. In addition, the ECM’s
feature a solid state, auto-ranging power supply which is independent of the meter power
supply and can be easily retrofitted with multiple antenna options.
For communication with various devices in a ZigBee Smart Energy Home Area Network
(HAN), the ECM’s also have an optional integrated 100mW ZigBee module that is Smart
Energy 1.0 certified and Smart Energy 2.0 ready. The ZigBee module firmware can be
upgraded Over The Air (OTA) enabling easy migration from SE 1.0 to SE 2.0.
Each Utiliwise® Endpoint, as a standard feature, hosts a webpage for diagnostics and control
similar to the one shown in

2. UTILIWISE® ENDPOINT CONFIGURATION AND COMMUNICATION
Although the Utiliwise® Endpoints are usually shipped with activated modems, customers should
always perform a “Settings” check before field installation which is also the first step in
troubleshooting a Utiliwise® Endpoint.
2.1. UTILIWISE® ENDPOINT CONFIGURATION PROCEDURE
2.1.1. CONNECT USB CABLE TO THE UTILIWISE® ENDPOINT
The Metrum USB driver package is included on the Metrum CD with your order and is also
available for download from the Metrum website at www.metrum.us/login where you will need
your login credentials. The first step is to power-up the UtiliWise® Endpoint and connect the
supplied USB cable which is a standard USB Mini cable. Connect the USB A end of the
supplied cable to a USB port on your computer, and connect the USB Mini end of the cable to
the exposed mini connector on the UtiliWise® Endpoint. The locations of the USB connector
under the cover of the UtiliWise® Endpoint meter platforms are shown in Figures 3-7 below.

When the Windows® new hardware wizard prompts for driver installation, browse to the Metrum
USB folder where the driver is located. Once installed, follow the steps below.
1. Open Device Manager.
2. Open the Properties window for the Metrum USB.
3. Verify the COM port number for use in the Metrum Configurator application described in
the next section
4. Verify the baud rate is set to 115200.
5. Click "OK" to close the Properties dialog window and exit Device Manager.
Once the USB cable is connected, apply power to the meter if not already powered up and
ensure the LED’s on the UtiliWise® ECM are lit before continuing. On each of the Metrum
Utiliwise® ECM’s, there are 4 LED’s placed near each other and labeled D10, D11, D12, and
D13. These LED’s indicate the state of the ECM and are described in the table below.

All four LEDs above blink Red simultaneously once the ECM acquires its mobile IP and then every
10 seconds thereafter verifying it has not lost connectivity.
2.1.2. INSTALL METRUM CONFIGURATOR SOFTWARE
The Metrum Configurator is the software used to perform a “Settings” check before field
installation of the Utiliwise® Endpoint. It is compatible with Microsoft Windows® operating
systems 98SE and later. Follow the steps below to install Configurator on your PC.
1. Copy the Configurator folder from the supplied Metrum CD-ROM to the desired location
on your hard drive e.g. “C:\Program Files\Metrum”.

2. Open the folder you copied and right click on “Configurator.exe” and create a shortcut to
the program on your desktop.
3. Open the Configurator software by double-clicking, or single-clicking depend on your
Windows settings on the icon.
2.1.3. USE THE METRUM CONFIGURATOR TO VERIFY ENDPOINT SETTINGS
First, verify you have the correct COM port selected in the top right corner (e.g. COM1, COM2,
etc.); the default is set to COM1. While the Utiliwise® Endpoint is connected via the USB cable
to the computer, click on the “ModemStatus” button as shown in Figure 8 below.
Note: The software will only work with the USB cable attached to the ECM. If an invalid COM
port is selected, you will receive a timeout error message. If you receive a timeout error, retry
the operation again. If you are still unsuccessful, cycle the power to the unit, reseat the cable
connector, and retry.

In this AT command listing, the settings to note are shown in
Figure 10 below.
FIGURE 10 METRUM CONFIGURATOR AT COMMAND SETTINGS OF INTEREST
If the ECM has a valid IP address, SSID, phone number, Modem Identifier Number, and an
RSSI greater than -110, the ECM is configured correctly and ready for IP communication.
Note: The default meter socket and ZigBee socket are 1700 and 1200 respectively, but these
can be changed in Configurator by changing the default values in the socket fields and clicking
on “Configure.”
2.1.4. ECM CONFIGURATION FEATURES FOR THE VERIZON NETWORK
Upon initial power up of a newly activated modem on the Verizon network, the ECM will
automatically acquire and program its MDN and MIN. This process can take up to 5 minutes to
complete during which time you will not be able to communicate remotely with the meter. Three
14
minutes after every subsequent power cycle and approximately every thirty days the ECM will
perform an over-the-air self-activation (OTA) and PRL (Preferred Roaming List) update.
2.2. IP COMMUNICATION PROCEDURE FOR METRUM WIRELESS ECM’S
Note: For ECM’s activated on the Verizon or AT&T networks, the IP communication procedure
should be coordinated with the carrier in terms of VPN access, etc.
For ECM’s activated on the Metrum Wireless Network, there are 2 ways to establish IP
communication with the Utiliwise® Endpoint using a VPN connection depending on the way the
head-end meter-reading software is setup.
2.2.1. CISCO ANYCONNECT
Using the Cisco AnyConnect VPN client is the preferred VPN connection method for customers
reading Utiliwise® Endpoints over the Metrum Wireless Network (MWN) from a single host or
remote location with meter reading software. All Metrum Wireless Network (MWN) customers
that use the Cisco AnyConnect VPN client has an access control list (ACL) applied to their user
credentials which allow access only to customers assigned Metrum Wireless IP addresses with
all others denied.
This is not recommended for customers using automated server side meter reading software
systems or customers that have multiple hosts with metering software on their local area
network (LAN).
15
Cisco AnyConnect is compatible with the following Operating Systems.
Windows XP SP2 and SP3
Windows Vista (32-bit and 64-bit) SP2 or Vista Service Pack 1 with KB952876
Windows 7 (32-bit and 64-bit)
Red Hat Enterprise Linux 5 Desktop
Ubuntu 9.x
Mac OS X 10.5, and Mac OS X 10.6, 10.6.1, 10.6.2 (32-bit and 64-bit)
2.2.2. SITE-TO-SITE VPN TUNNEL
A site-to-site VPN tunnel is the preferred hardware VPN connection for customers reading
Utiliwise® Endpoints over the Metrum Wireless Network (MWN) that have automated server
side meter reading software systems or that have multiple hosts with metering software on
their local area network (LAN). All Metrum Wireless Network (MWN) customers that have a site-
to-site VPN tunnel with Metrum has a group policy in place with an access control list (ACL)
applied to it. This allows access only to customers assigned Metrum Wireless IP addresses with
all others denied.
