How it works
The router connects to the mobile network and shares the connection with your devices through its Ethernet ports and Wi-Fi. At the same time its RS232 and RS485 ports read serial devices and send the data to your server using Modbus, MQTT or your own program. VPN tunnels keep the traffic secure.
