Page 3: Chapter 1. Introduction
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. - Page 4 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.
- Page 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) operating wireless network by configuring the APN,...

The SIM card is replaceable by pushing the inserted SIM card –... - Page 9 2.5 Connecting the modem the Elster AS3000, AS3500 meter ® Remove Elster AS3000/AS3500 ® meter’s communication module plastic case by releasing the screw from the top middle part of the housing. ANTENNA MODEM METER 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).
- Page 10 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.
- Page 11 The interface connector (3) is close to the SMA antenna connector (6) (right top side on the picture). At the center of the modem, you will found two plastic hooks, which helps you at the fixation into the enclosure. (If you want to remove the modem, push these hooks carefully, and it’s free to remove the module from enclosure’s case.)
- Page 12 The meter’s terminal module housing upper right edge is a rounded as a sign of the perfect slide fit the adaptation to the meter. After assembling, attaching the modem terminal unit and turning on the meter, the modem will be immediately powered on, and its operation is confirmed by the LED signals.

2.6 Antenna connection For proper operation of the communication module it is necessary to have appropriate cellular network signal strength. At the locations, where the signal strength is strong it is possible to use internal antenna, for areas with poor reception mount an external antenna (50 Ohm SMA- M connected) to the antenna connector (6) of the device. - Page 15 Factory default LED signals: LED identifier Events • During network registration: led is active • During network search: blinking once per second • When connected to the network and the IP connection is fine: flashing twice per second LED 1 •...

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. - Page 19 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 –...

3.4 Parameter configuration The general operation requires to make the cellular communication settings and SIM settings of the modem (APN, APN username, password and PIN code, network usage method). The meter communication requires to define the communication port, the RS232 settings (transparent mode,... - Page 23 5. The RS232 serial data port transparent settings can be made at the Trans. / NTA parameter group. The default settings: Multi utility mode: transparent mode, Meter port baud rate: 9600, Fix 8N1 data format at meter – enable the checkbox). Then push to the OK button.
- Page 24 6. The MBus settings can be configured in the MBus parameter group. 7. Reading M-Bus meters with HHU on Optical interface After the Elster meter is operating in transparent mode, a second address needs to be opened for the connection on the M-Bus channel. Important! This and further M-Bus communication are working with 9600 8N1 frame.
