Page 3: Chapter 1. Introduction
Chapter 1. Introduction The WM-E2S modem is suitable for remote reading of electricity meters on LTE- ® based cellular networks. You can save money by using our modem, because there is no further need of manual readout of the meter systems. - Page 4 parameter set of the meter - remotely. The date readout from the meter takes place in "PULL" mode, when the modem provides transparent communication between the meter and the electricity provider's measurement center (HES). Data is sent via the mobile network corresponding to the selected module. The modem can be accessed remotely through the cellular network (by the Telit ®...

- Page 9 2.4 Jumperless (crossboard) version The modem can be ordered in jumperless version (crossboard soldered to the PCB, instead of a jumper board). It has a pre-defined connection according to the meter type. Therefore, there is no need for manual jumpering of the device, all settings can be done by the WM-E Term configuration software directly –...

Page 11: Installation Steps
2.5 Installation steps Step #1: Remove the top cover or the meter (18) by loosing its screws. Step #2: Ensure that the modem is not powered – remove the RJ45 connection cable (14) from the meter side. Step #3: Loose the cover holders (4) of the plastic enclosure’s white part (1b) at the edges, while pull the plastic top cover (1a) - from right-down to left-up direction –... - Page 12 Step #4: Now the PCB (2) will be on the left side – see the photo. Step #5: Slide and open up the plastic SIM card holder (8) - push from left to right, and spin it up until release. Step #6: Insert a replaceable and active SIM card (with APN) into the SIM-holder (8) - the chip looks down,...
- Page 13 Step #10: The data connection between the modem and Itrón meter is assured by ® the RS232/RS485 interface (RJ45, signed with nr. 10 on the figure), then it can be used with the grey RJ45 cable - provided. Step #11: Place and insert the modem into the meter (under the meter’s terminal cover) and fix the device to the meter –...
- Page 14 Step #16: Reconnect the RJ45 cable to the meter. (If the modem will be connected on RS485 port with the meter, then the jumper settings must be modified to RS485 mode!) ITRON ACE6000 → WM-E2S modem connection...

Page 22: Chapter 3. Modem Configuration
Chapter 3. Modem Configuration 3.1 Configuration The modem is uploaded with default configuration, but before the first usage the current settings should be checked and the configuration should be updated (e.g. APN name, etc.). The WM-E Term software is usable to perform the modem settings. ®... - Page 23 The configuration can be made by CSData call (by selecting a mobile access technology which uses 2G network). Or you can do it through mobile internet (TCP) connection – therefore you don’t need to connect the modem to your PC. Important! During the configuration, the power supply of the modem is assured by this converter board, on USB connection.
- Page 24 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 WM-E2S modem was not ®...
