3Wire RS2MQTT/RS2MQTT+ | 4G MQTT Gateway

Introduction

3Wire RS2MQTT & RS2MQTT+ are both Industrial Grade 4G IoT Gateway which connects your Serial and Ethernet* devices, such as PLCs, meters and sensors to an IoT platform.

Both are able to poll the required data from your Serial devices and send it as MQTT or HTTP Post over GPRS or LTE network. You can conﬁgure the connected devices thru the serial port, conﬁguring and deﬁning the required data and interval.

Upto 800 data records are stored in its internal cache memory to prevent data loss if the 2G / 4G connection is lost. The unit also comes with specially designed watchdog circuit to ensure stable continuous operation of 4G connectivity.
