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 RJ45 connection from the meter. (The power source will be removed.)
-
Step #3: Push the ears (3) and open up the enclosure’s top cover (1) at the antenna connector. The PCB will be free to touch.
-
Step #4: Push the plastic SIM holder’s cover (8) from right to left direction, and open it up.
-
Step #5: Insert an active SIM card into the holder (8). Take care to the right position
(the chip looks down, the card’s cutted edge looks outside to the antenna. Push the SIM into the guiding rail, close the SIM holder, and push back the SIM holder (8) from left to right direction, and close it back. -
Step #6: Ensure that the antenna’s internal black cable is connected onto the U.FL connector (11)!
-
Step #7: Check that the internal data cable (5) is connected to the PCB (2), to the data connector interface (6).
-
Step #8: Mount an antenna to the FME antenna connector (5). (If you’re using an SMA antenna, then use SMA-FME converter).
-
Step #9: Connect the modem to the computer by the RJ45 cable and the RJ45-USB converter, and set up the jumper’s position into RS232 mode. (the modem can be configured only in
RS232 mode through cable!) -
Step #10: Configure the modem by the WM-E Term® software.
-
Step #11: After the configuration remove the RJ45-USB adapter from the cable and the modem’s power supply will be ceased.
-
Step #12: Close back the modem enclosure cover (1) by its fastener ears (3) to the meter enclosure. You will hear a click sound when closed.
-
Step #13: Put and install the modem to the meter’s fastener/fixation points and fasten the modem into the meter house/enclosure.
-
Step #14: The modem-Landis+Gyr® meter connection can be initiated via RS232 port by a 1:1 cable connection. Therefore use the beige RJ45 cable (5) of the modem to connecto to to the RJ45 port of the meter.
-
Step #15: The modem will be powered by the meter immediately and it’s operation will be started. The device activity can be checked with the LEDs.
OPERATION LED SIGNALS – IN CASE OF CHARGING
Attention! The modem must be charged before the first use – or if it was not been powered for of long time. The charge takes about ~2 minutes if the supercapacitor was exhausted / discharged.
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-E2SL ® modem’s Installation Manual.
Important! Note, that during the firmware uploading the LEDs are operating as it is normal – there is no significal LED signal for the FW refresh progress. After the Firmware installation, the 3 LEDS will be lighting for 5 seconds and all will blank, then the modem restarting by the new firmware. Then all LED signals will be used as it was listed here above.
CONFIGURATION OF THE MODEM
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:
-
During the configuration process, the RJ45 (5) connector must be removed from the meter connector and should be connected to the PC. During the PC connection the meter data cannot be received by the modem.
-
Connect the modem to the computer by the RJ45 cable and the RJ45-USB converter. The jumpers must be in RS232 position!
Important! During the configuration, the power supply of the modem is assured by this converter board, on USB connection.
Some computers can sensitive for USB current changes. In this case you should use an external power supply with special connection. -
After the configuration reconnect the RJ45 cable to the meter!
-
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.
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_63.zip file. Uncompress and start the wm-term.exe file.
- Step #2: Push the Login button and choose the WM-E2S 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 the 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. Then push the Save button to create the serial connection profile.
- Step #5: At the bottom left side of the screen choose a connection type (serial).
- 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. (check the status again).
- 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.
*If you are using data call (CSD) or TCP/IP connection remotely for the modem connection – check the Installation manual for the connection parameters!
Parameter configuration
-
Step #1: Download a WM-E Term sample configuration file. Choose the File / Load menu to load the file:
https://m2mserver.com/m2m-downloads/WM-E2SL-STD-DEFAULT-CONFIG.zip -
Step #2: At the Parameter group choose the APN group, 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 the M2M parameter group, then push to the Edit values button. Give the 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. Choose a Mobile network technology (e.g. All available network technology – which is recommended to select) or choose the LTE to 2G (for „fallback”).
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 the RS485 meter interface parameter group, you should disable the RS485 mode. Then push to the OK button.
-
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.
-
Step #8: If you want to use the modem via RS485 for meter readout, then you have to modify the jumpers to RS485 mode!
Further setting options
- The modem handling can be refined at the Watchdog parameter group.
- The configured parameters should be save to your computer also by 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!
