Global connectivity with 4G LTE-M
LTE-M is the abbreviation for LTE Cat-M1 or Long Term Evolution (4G), category M1. This cellular technology is designed to connect Internet of Things devices to existing 4G towers while using low energy. LTE-M does support handovers and roaming so it is possible to use this device in a moving vehicle like a campervan. Check the list in our GlobalLink 520 manual to see if LTE-M is officially confirmed to be available in your area. Coverage is increasing every week as local providers roll out support. Your purchase includes 5 years of connectivity, so there is no need to worry about purchasing a separate data bundle and SIM-card.
System monitoring & control
The GlobalLink 520 comes with two communication ports, which allows connecting up to two VE.Direct devices such as a BMV Battery Monitor and/or a MPPT Solar Charge Controller directly to VRM. With two digital inputs that also act as pulse counters and a remote controllable relay, it’s a perfect solution to monitor and control your installation.
The GlobalLink 520 comes with a built-in antenna that is designed to work all around the globe. However if you require better reception or want to install your module in a utility van for example, it is also possible to mount an external antenna.
