Chapter 1. Introduction
Our company develops cellular modems that work smoothly and are fully
compatible with the Honeywell / Elster electricity meters, which represent a future-
proof migration solution to the LTE network.
This modem can be readout (the measured energy consumption of the connected
electricity meters) remotely for the request of the HES center.
The modem can also read out the alarms of the meters, then push them to the
HES center by DLMS protocol.
Connection possibilities:
• 1 electricity meter to the modem
• 4 water meters (MBUS) to the modem
The water meters are readout by the modem, the consumption can be
readout in „pull” mode via DLMS protocol.
The device was designed to fit under the terminal cover of the meter and it is
compliant with the Honeywell / Elster standards.
Configuration and firmware updates can be done remotely by the WM-E Term®
software, minimizing the need for costly site visits.
Wireless communication
The modem supports the multi-operator SIM and the roaming feature, and it is
compatible with SIM-Toolkit.
The communication module is a part of the Smart Metering concept.
The device provides a SIM-card independent- and mobile operator independent
solution.
Design and compatibility
The communication module is a part of the Smart Metering concept. The modem
was especially developed for Elster®/ Honeywell®AS3000/AS3500 type electricity
meters, but can be connected to IEC meter or M-Bus capable water meters.

The modem can be connected to the meter by sliding into the meter’s
communication module slot and there it can be sealed.
Thus, the modem presents a compact solution, the dimensions of the meter will
not change if a modem if fitted or not. This solution offers the possibility of future
upgrade of the electricity meter with a communication module and is ideal for
installations where there is restricted assembling space.
Operation properties, features
The modem is suitable for readout and send the meter’s actual and stored
consumption values, access the recorded event log, read the load profile data. Able
to read or modify the parameter set of the meter device - remotely. It can be
accessed remotely through the cellular network (by the Telit®module) and it is able
to send data on the Internet by using an APN.
Power source and power outage
The modem is powered by 230V AC power through the meter’s integrated mains
connector.

Supercapacitor
The device is equipped with supercapacitors, which are preventing the
intermittent power cuts and help decrease power peaks. It is enabling to keep the
module in operation during small power outages (for max. 2 minutes).
Configuration
The modem is configurable via TCP/UDP port remotely (or via local serial
connection) and operating on the
wireless network by configuring the APN,
username and password (APN
information is provided by your local
mobile operator).
All settings can be configured with our
administration tool - the WM-E Term®
software - but also API available so our
partner can easily adapt their current administration environment.
. The configuration is possible for singular or multiply devices. The WM-E Term®
software is password protected and user management is also possible. The
multilingual configuration tool requires Windows®platform to be executed.
Firmware refresh
The WM-E Term®also provides safe firmware change for one or group of devices –
by locally or remotely.

2.8 MBUS connection
There are two modes of connecting MBUS
meters to the modem (currently max. 2 MBUS
capable water meters). You cannot use the
two type of MBUS connection in the same
time, therefore choose one wiring mode of the
following options, please.
Option a)
There is an MBUS input connector (13) on the modem’s MBUS expansion part.
By using this interface –according to the PCB printed wiring polarity –connect the
external meter to this interface
Option b)
You can use the MBUS capable electricity meter’s
auxiliary terminal block for connecting MBUS
meters. This is connected through the modem’s
internal data connection (12). Check the proper
wiring polarity in the meter’s user manual.
2.9 Push button
The modem has a push button (2). After assembling the modem into the meter’s
enclosure, you can use the external button to adjust. When using the button:
- by short pushing: the wireless network signal strength will be signed on
the LEDs 1-4 (more LED signals meaning better signal)
- by longer pushing (for 3-5 seconds) –until all the 6 LEDs will be blinking
once: the used network technology will be signed by the following:
oLED2 will be active: when 2G network is used
oLED3 will be active: when 3G network is used
oLED4 will be active: when 4G network is used
oetc.

2.10 Power outage management
The LastGasp notification (SMS feature) is currently inactive –not implemented yet.
The supercapacitors are active and will provide termporary power source for the
modem, during the power outage –for max. 2 minutes.
The power outage is not signed by the LED signals.
After the recovery of the AC power source the supercapacitors will be automatically
charged –ca. 2-5 minutes is required for the full charge.
When the notification will be available, the LastGASP message settings can be
enabled by the WM-E Term®application –in the AMM (IEC) parameter group part.

Chapter 3. Modem Installation Guide
The communication modems can be configured by the WM-E Term®software or
the DM Set®/ AlphaSet®software which is also suitable for setup the electricity
meter through a serial connection.
The WM-E Term®tool is suitable over the communication settings to readout the
data and registers and the MBus data of connected meters.
Over the parameter settings of meter, modem and communication, you can also
test the modem communication by the configuration program.
Important!
During the configuration the modem is not connected to the meter, therefore it
cannot readout the parameter values through the meter-modem interface.
We offer to use the WM-E Term®configuration software to perform the settings
according its user manual –check the manual for settings.
For the proper communication of the modem, you have to configure at least the
APN settings of the SIM –as PIN code, APN, username and password. These all can
be configured by using the WM-E Term®software.
For the successful operation of the communication module it is necessary to have
appropriate signal strength.
3.1 Configuring the modem by WM-E Term
®
The Microsoft .NET framework runtime environment is required on your computer.
For modem configuration and testing you will need an APN/data package enabled,
active SIM-card with.
Sure, the configuration is possible without a SIM card, but in this case the modem
is performing restart periodically, and some modem features will be not available
until the SIM card is inserted (e.g. remote access).
If the modem was not supplied by power for a long time, it needs to be charged
before usage.
