Cerbo GX Manual

3. Internet connectivity

Connect the Cerbo GX to the internet to get all the advantages of the VRM Portal. The Cerbo GX sends data from all connected

products to the VRM portal - from where you can monitor energy usage, view the current status of connected products, config-

ure email alarms and download data in CSV and Excel formats.

To monitor this data from your smartphone or tablet download the iOS or Android VRM App.

In addition to remote monitoring, an active internet connection allows the Cerbo GX to regularly check for a new firmware ver-

sions - which will be automatically downloaded and installed.

There are several ways to connect a Cerbo GX to the internet:

• Run a network cable between a router and the Cerbo GX Ethernet LAN port

• Connect to the router wirelessly using WiFi

• Via the mobile (cellular) network, using the GX GSM - a cellular USB modem or, with a 3G or 4G router.

• USB Tethering on a mobile phone
