If the battery status does not allow for the immediate issue of the power loss alarm, it will be sent when
the concentrator reboots.
2.4.2 Cellular Network
The WebdynSunPM concentrator has a built-in 2G/3G or 2G/4G network compatible modem.
2.4.2.1 Antenna
The concentrator has a female SMA connector available at the front of the product to connect a modem
antenna. The product is delivered with an angled SMA antenna taped to the back of the box. It can be
replaced with other compatible antennas.
If the WebdynSunPM concentrator is installed in a metal box or in a location that does not have
proper signal reception, the use of an offset antenna is strongly recommended. Be careful to use an
antenna compatible with the connector and frequencies used.
End users must make sure their installation using remote antennas meets applicable EMC
standards.
2.4.2.2 SIM Card
To use the 2G/3G or 2G/4G modem connection and allow the concentrator to communicate with the
remote server or servers, a mini SIM format SIM card must be inserted in the SIM card housing on the
front of the concentrator.
