INSTALLATION STEPS
Step #1: Remove the meter terminal cover by its screws (with a screwdriver).
Step #2: Ensure that the modem is NOT under power supply, remove the AC connector from
the meter. (The power source will be removed.)
Step #3: Insert a replaceable and active SIM card (with APN) into the SIM- holder (4) – the chip
looks down, and the cutted edge of the SIM looks to the modem. Push the SIM until it will be
fastened (you will hear a click sound). If it is necessary, the SIM card can be easily removed by
pressing the card again, causing the card to be ejected from the tray.
Step #4: Install the modem enclosure (5) and fasten near to the meter or mount to the wall in
a fixed position. You can insert the device into the internal mounting points of the meter – under
the meter terminal cover – and attach it to the meter terminal cover according to the meter’s user guide.

Step #5: Mount an external magnetic base or stick LTE antenna to the antenna connector (3).
Step #6: Connect the modem to your computer with the RS232 cable (2) (RJ12 connector) and use an RJ12-USB adapter.
Step #7: Connect the modem’s AC power connector (1) – wire socket connection or “pigtail” connector depending on the version – to the meter
power input (for 100-240V AC) or to an external 240V power supply.
Step #8: Configure the modem with the WM-E Term® software via RS232 port PC connection. (For further details see the next chapter).
Step #9: After completing the configuration, remove the R232
cable (or RJ12 cable) – labeled with ,,2″ – from USB adapter. Step #10: Disconnect the modem AC power connector (1) from
the meter (or power source). The modem will be shutting down.
Step #11: Make a data connection between the modem
meter on the interface you want to use (port nr. ,,2″ – RS232 data
connection). If the modem has RS485 port, then make data
connection between the modem meter by RS485 cable.
Step #12: Connect back the modem’s AC power connector (1) –
wire socket connection or “pigtail” connector depending on the
version – to the meter’s power input (for 100-240V AC). The modem will be powered by the meter and the modem will starting its operation
and the LED signals are signing the current activity. Place back the terminal cover of the meter and secure with the screws.
OPERATION LED SIGNALS
LED identifier
Events
LED1 GSM / GPRS status
· If there is a SIM and PIN code ok, the LED will turn on · If there is no SIM
or the SIM PIN is incorrect, the LED flashes every 1 second. · If there is no
SIM, the LED flashes every 1 second. · RSSI flashes the LED according to the
field strength value (1 flash lasts for 1 second, followed by a pause):
RSSI <= -98 1 flashing RSSI> -98 and <= -83 2 flashing RSSI> -83 and <= -68 3
flashes RSSI> -68 4 flashes
LED 3 SIM status / SIM failure or PIN failure
· During network registration: led is active · During network search: blinking
once per second · When connected to the network and the IP connection is okay:
blinking twice per second · When the mobile network access technology was
changed: quick flashing will be relied:
2G 2 flashing per second 3G 3 flashing per second 4G LTE 4 flashing per second
· If no network is detected: the led will be blank · During the CSD call and
IP data transmitting the LED is lighting continuously
LED2 E-meter status
· During the transparent meter communication: twice per second. · At finish of the transparent communication: led is blank. · According the IEC meter status: the LED will be active. · In case of configuring the Multi Utility mode: led will be active or blank.
Note, that over the factory defaults, the operation and the sequence of the LED signals can be changed by the WM-E Term® configuration tool, at the General Meter Settings parameter group. The free to choose further LED options can be found in the WM-E1SL® modem’s Installation Manual.
CONFIGURATION OF THE MODEM The modem can be configured with the WM-E Term®
software by setup of its parameters. This must be done before the operation
and usage. Connect the modem to the computer by its RS232 cable and the
RS232-USB converter. For the serial cable connection configure COM port
settings of the connected computer according to the modem serial port
properties in the
Windows at the a Start menu / Control panel / Device Manager / Ports (COM and
LTP) at the Properties: Bit/sec: 9600, Data bits: 8, Parity: None, Stopbits:
1, Bandwith control: No The configuration can be performed via CSData call or
TCP connection if the APN is already configured. Read Installation manual for
CSD settings.)
MODEM CONFIGURATION BY THE 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, an active SIM-card. 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).
Connection to the modem (via RS232 port*) Step #1: Download the
https://www.m2mserver.com/m2m-downloads/WM_ETerm_v1_3_80.zip file. Uncompress
and start the wm-eterm.exe file.
Step #2: Push the Login button and choose the WM-E1S device by it’s Select
button.
Step #3: At left on the screen, at the Connection type tab, choose the Serial
tab, and fill the New connection field (new connection profile name) and push
the Create button.
Step #4: Choose the proper COM port and configure the Data transmission speed
to 9600 baud (in Windows® you have to configure the same speed). The Data
format value should be 8,N,1. Push Save button to make a connection profile.
Step #5: At bottom left side of screen choose the ,,Serial port” connection
type .
Step #6: Choose the Device information icon from the menu and check the RSSI
value, that the signal strength is enough and the antenna position is right or
not. (The indicator should be at least yellow (average signal) or green (good
signal quality). If you have weak values, change the antenna position while
you will not receive better dBm value. (you have to request the status again
by the icon).
Step #7: Choose the Parameter readout icon for the modem connection. The modem
will be connected and its parameter values, identifiers will be read out.
Parameter configuration Step #1: Download a WM-E Term sample configuration
file https://www.m2mserver.com/m2m-downloads/WM-E1SL_STD_default.zip and
uncompress the file. Then choose the File / Load menu to load the sample
configuration file. Edit parameter settings by following these steps.
Step #2: On the screen at bottom, choose the Advanced settings button and
choose the Parameter group: APN, then push to the Edit values button. Define
the APN server and in case of neccassary the APN Username and APN password
fields, and push to the OK button.
Step #3: Choose M2M parameter group, then push Edit values button. Add PORT
number to the Transparent (IEC) meter readout port field which will be used
for the remote meter readout. Give the configuration PORT NUMBER to the
Configuration and firmware download port.
Step #4: If the SIM is using a SIM PIN, then you have to define it to the
Mobile network parameter group, and give it into the SIM PIN field. Here you
can choose the Mobile technology (e.g. All available network technology –
which is recommended to select) or choose the LTE to 2G (fallback) for network
connection. You can also select a mobile operator and network as automatic or
manual. Then push to the OK button.
Step #5: The RS232 serial port and transparent settings can be found in the
Trans. / NTA parameter group. The default settings are the following: at Multi
utility mode: transzparent mode, Meter port baud rate: 9600, Data format:
Fixed 8N1). Then push to the OK button.
Step #6: In case of RS485, the RS485 settings can be performed in the RS485
meter interface parameter group. The RS485 mode can be setup here.
Step #7: After the settings you have to choose the Parameter write icon to
send the settings to the modem. You can see the progress of the upload at the
bottom status’s progress bar. At the end of the progress the modem will be
restarted and will be starting with the new settings.
Further setting options The modem handling can be refined at the Watchdog
parameter group. Configured parameters can be saved to your PC in the
File/Save menu.
Firmware upgrade: select the Devices menu, and the Single Firmware upload item
(where you can upload the proper.DWL extension file). After the progress of
the upload, the modem will be rebooting and operating with the new firmware
and the previous setttings!
