DRAGINO MS48-LR - LoRaWAN To Modbus Gateway

MS48-LR-868 ( without 4G/LTE )

Overview

The MS48-LR is an open-source LoRaWAN to Modbus gateway. It enables the connection of a LoRa radio network to an IP network via WiFi, Ethernet or a mobile network (via an optional 4G module). The LoRa radio network enables users to send data and achieve extremely long ranges at low data rates.

The MS48-LR is fully compatible with the LoRaWAN protocol. The MS48-LR has a built-in LoRaWAN server and an IoT server. The user can connect virous LoRaWAN devices to the MS48-LR and use the PLC to access these devices via the Modbus network.

Different countries use different LoRaWAN frequency bands. The MS48-LR has preconfigured these bands. Users can also customise the frequency bands for use in their own LoRa network.

MS48-LR supports remote management. System integrators can easily monitor and maintain the gateway remotely.
