Connecting to a meter
After the successful configuration, disconnect the RS232 cable from your PC and use an RS232 cable or a RS485 cable (2-wire or 4-wire) from the RJ45 port to the meter – which has the primary RS485 port also. Optionally you can also use the secondary RS485 port (of the terminal block). Any further settings can be perfomed by hints of the WM-E Term User Manual: https://www.m2mserver.com/m2mdownloads/WMETERM_User_Manual_V1_93.pdf

Signal strength
Check signal strength of the cellular network in the WM-E Term® software Device  Information menu or by using the icon. Check RSSI value (at least it should be yellow – which means average signal strength – or better if it is green). You can change the antenna position while you will not receive better dBm values (the status must be readout again for refresh).

Power outage management
The firmware version of the modem is supporting the LastGASP feature, whichmeans that in case of power outage the modem’s supercapacitor allows to operating further the modem for a short time (a couple of minutes). In case of detecting the loss of mains/input power source, the modem generates a “POWER LOST” event and the message will be immediately transmitted as an SMS text to the configured phone number. In case of recovering the mains/power source the modem generates the “POWER RETURN” message and sending by SMS text. The LastGASP message settings can be enabled by the WM-E Term® application – in the AMM (IEC) parameter group part.
