Page 3: Chapter 1. Introduction
Chapter 1. Introduction The WM-E1S 4G ® is a modem, which is suitable for automated remote reading of electricity meters remotely, on the 4G LTE-based cellular network. You can save money by using our modem, because there is no further need of manual readout of the connected meter systems. - Page 4 The modem can be connected through the following modes: a.) the meter is connected to the 57.7/100V AC power network: the modem must be connected to phase voltage (100V, L1..L2 or L2..L3 or L1..L3) b.) the meter is connected to the 230/400V AC power network: the modem must be connected to the line voltage (230V, L1..N or L2..N or L3..N) Configuration The modem is configurable via TCP/UDP port remotely (or via local serial connection) and...
- Page 5 Certification The modem is accomplishing with the CE standard and the Radio Equipment Directive (2014/53/EU), safety directives (EN 60950-1).

2.2 Installation steps Step #1: Ensure that the device is not powered on or remove the AC connector (1) from the meter. Step #2 : Insert a replaceable and active SIM card (which uses APN) into the SIM-holder (4). The SIM chip looks down, the cutted edge of the SIM is oriented to inside of the modem. - Page 8 Step #7: Connect the modem’s RJ45 data cable (9) to the modem’s RJ45 port (2) to the meter’s RS232 port. Step #8: Connect the modem’s AC Power plug (1) to the meter’s Power input line (in case of using 100V AC) or connect to 2-phase (in case of using 57.7V voltage as power source). Step #9: Then the modem will be power supplied by the meter and the modem will start its operation and the LED signals are signing the current activity.

Chapter 3. Modem Configuration 3.1 Configuration 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. Over the parameter settings of meter, modem and communication, you can also test the modem communication by the configuration program. - Page 13 3.2 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.

Check the RSSI value that the available signal strength is enough (yellow means average signal quality and the green means the good). When you get poor signal quality, change the antenna position or direction until you will receive better dBm value (the status must be read again bedfore recheck). - Page 15 Main settings: 1. Choose the Parameter read icon to connect to readout the current settings of the modem. Parameter group APN server 2. Choose the APN , and push to the Edit settings button. Add the name APN username APN password value, if necessary give the values and push to the OK button.
- Page 16 Chapter 5. Legend GSM (Global System for Mobile Communications) is the most popular standard for mobile telephony systems in the world. GSM is a cellular network, which means that mobile phones connect to it by searching for cells in the immediate vicinity. GPRS General Packet Radio Service (GPRS) provides more efficient packet-based data transmission directly from the mobile phone at speeds similar to HSCSD.
