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.

5
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.
Certification
The modem is accomplishing with CE standard (Radio Equipment Directive
(2014/53/EU)) and safety directives (EN 60950-1) and RoHS declaration.

We deliver the modem as assembled product - as it is shown in the picture
2.4 Inserting a SIM card
Insert an activated SIM card into the push-insert SIM card slot (4). The SIM card is
replaceable by pushing the inserted SIM card –if it is necessary.
The SIM-cad PIN code can be configured by the WM-E Term®application.

2.5 Connecting the modem the Elster® AS3000, AS3500 meter
Remove the Elster®AS3000/AS3500
meter’s communication module plastic
case by releasing the screw from the top
middle part of the housing.
Inside the communication unit’s case mount the SMA-M antenna interface
connector (6) on the housing (fix it with the SMA connector’s screw).

Snap the modem unit (mainboard + expansion board) into the communication
module terminal’s plastic enclosure by sliding into, through the guiding rails of the
case. Insert the modem into the right orientation into the slot. Check the 12-pin
data connector (3) position –according the next picture.
Push the modem into the terminal enclosure, until you’ll hear a click sound.
