- Page 3 Chapter 1. Introduction WM-E3S is an integrated modem unit PCB. It is suitable for remote reading of ® electricity meters. The modem family has several versions to fit for many meter types. You can save money by using our modem, because furthermore there is no need of manual readout of the meter systems.
- Page 4 The device can be installed under the sealed terminal cover of the electricity meter without replacing the seal certifying the first verification or the non-destructively sealed measuring housing. The modem can be connected to the meter by sliding into the meters’ communication module slot and 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.
- Page 5 Supercapacitor The modem is also available with a power outage protection by an optional supercapacitor component, which allows to continue the modem operation in case of minor power outage(s). In case of a power outage, the supercapacitors will discharge by time, and the modem will shut down.
- Page 6 The control port of the modem is encrypted by AES (by option), or can be ordered with TLS protocol usage. The external flash- and the internal flash content of the device are encrypted. All security protocols can be activated/deactivated by authorized client. Status and notification The modem is continuously monitoring the mobile network and device communication health, and can send status information (signal strength, QoS).

The SIM card is easily replaceable by pushing the inserted SIM card when it is necessary. 2.3 Connecting the modem unit PCB to the AS3000/AS3500 meter Take off the Honeywell / Elster...
- Page 9 Inside the communication unit’s case mount the SMA-M antenna interface connector (6) on the housing. Then fasten it with the SMA connector’s screw nut.
- Page 10 Now snap the modem unit PCB into the communication module’s plastic housing by sliding it through the guiding rails of the case until you hear a click sound. Beware to place the modem unit PCB orientation into the slot. The 12-pins data connector (3) can help You to find the right position (upper right in the figure).
- Page 11 Now we can connect the communication module to the meter by sliding the communication unit into the meter housing. The communication interface (3) and the mains connectors (1) must be connected to the connector pairs from the meter housing. You will found, that the meter and communication module housing upper right edge is a rounded (radiused) as a sign of the perfect slide fit adaptation.
- Page 12 After assembling and turning on the meter the modem will be powered and its operation is confirmed by the LED signals (11).
- Page 13 2.4 Connecting the modem unit PCB to AS220, AS230, AS300 meter Disassemble the Elster AS220, AS230, AS300 meter’s communication module ® plastic case. Release the top screw at the middle and take off the upper modem unit case. The modem unit PCB can be placed into the transparent plastic housing...
- Page 14 2.5 Connecting the modem unit PCB to the AS1440 meter Connect the external PCB adapter with the 12 pins ribbon cable and slide the connector to the 12-pins communication interface (3) of the modem unit PCB as it can be seen in the picture. The wire marked with red must positioned...
- Page 15 Mount the SMA-M antenna connector back cover communication module by fixing it with the antenna SMA screw (part of the U.FL cable). Now insert the modem unit PCB inside terminal cover’s communication module housing by sliding it through the guiding rails that are closer to the fixing screws.
- Page 16 Place the external power supply adapter PCB into the terminal cover case at the proper direction as it can be seen in the picture. pins Microfit connector must oriented to upside, the 12- pins wire must be placed to the left side – as it shown on the picture.
- Page 17 After assembling and turning the meter on the communication module is ready for operation. The LED signals will confirm the operation status of the communication module. 2.7 Antenna connection For proper operation of the communication module, it is necessary to getting sufficient cellular network signal strength.
- Page 18 Factory default LED signals: LED identifier Events LED 1 • During network registration: led is active GSM / GPRS status • During network searching: blinking once per second • When connected to the network and the IP connection is okay: blinking twice per second •...
- Page 19 When the connection between the meter → modem is established, the LED flashes in every 2 seconds. *LED 4 operation is available only in case of presence of the WM-E3S CIR version. ** LED 5 operation is available only in case of presence of the MBUS version.
- Page 20 2.9 Push operation method The complete readout and data sending mechanism to the center and the other direction for the configuration and maintenance tasks can be realized on the defined paths. The modem does not operate continuously on the network. Therefore, there is another option and meter data sending mode to initiate a remote readout automatically in the pre-defined intervals.
- Page 21 • The file always consists of two parts, first a standard register read and then an event log (containing the events of the last 31 days). • The readings shown as standard IEC format, including some ASCII control characters like STX ETX, etc. also. - Alarm Push - starting when new event can be read from meter •...
- Page 22 • After closing the connection, the LED will turn off If you want a modem configuration / firmware update: - The LED configured for GSM / GPRS status will be lit continuously during the CSD call. - In this case, the other LEDs do not change due to the CSD mode. 2.11 Configuring from CSD connection If the modem restarts due to an incorrect configuration, it is possible to access it with a CSD call.
- Page 23 2. If there is no ping response, it reconnects to the network after the time interval specified in the Seconds, GPRS connection closed and restored after this time parameter. Attention! In case of frequent ping using, the data traffic will be higher, but the chances are higher that the device will remain on the cellular network.
- Page 24 The modem must be configured by the WM-E Term software by configuring its ® parameters which must be performed before the normal operation and usage. Important! The WM-E3S modem can be configured through meter’s RS485 ® connection, meter’s optical interface or via TCP connection settings.
- Page 25 3.2 Configuring the modem by WM-E Term ® The Microsoft .NET framework runtime environment is required on your computer. Download WM-E Term to your computer from the following location using a ® browser: https://m2mserver.com/m2m-downloads/WM-ETerm_v1_5.zip Then unzip the .zip file to a directory and execute the WM-ETerm.exe file. The configuration software supports user account management and password change.
- Page 26 which was configured at the meter side. It is worth configuring this primarily for alarms and special events, according to the capabilities of the meter. No other settings are required in WM-E Term ® 3.4 Signal strength Check signal strength of the cellular network in the WM-E Term software Device ®...
- Page 27 3.5 Power outage management – for supercapacitor expansion only! If supercapacitors are presented on the PCB or on the additional expansion board, then the firmware of the modem will support the LastGASP feature. This means that in case of power outage the modem’s supercapacitor allows to operating further the modem for a short time (a couple of minutes).
- Page 28 7. Afterall, the LED will be operating ordinary as it is listed in the LED operation behaviour description.
