Webdyn EasyTunnel 4G IoT modem

The Webdyn EasyTunnel 4G is a powerful, all-in-one IoT solution for demanding industrial, agricultural, utility and environmental applications. With RS232, RS485, dual SIM and digital I/O interfaces, plus embedded TITAN V6 firmware (Modbus, MQTT, IPSec, logger, webserver), the unit provides the required functionality for many complex IoT projects.

A key feature is the user-programmable scripts, based on JavaScript, that permit easy programming of customised functions for specific applications (edge computing). Additional functions include FIFO/LIFO modes for data queuing, SSL/TLS support, and data sending options (HTTP/HTTPs/FTP/FTPs/MQTT/MQTTs) with custom JSON formats.

Webdyn’s Titan V6 firmware comes with an embedded webserver to make configuration and setup simple and quick. Additional features of the firmware include: two simultaneous 4G-to-RS232/485 connections; serial data collected by RS232 or RS485 (Modbus, sensors, meters, I/Os); full control by SMS with phone number authorisations; alarms (digital input, temp, MBus data read); full management with AT Command by serial, socket, SMS, modbus, SNMP); SSH encryption, which supports TACACS+; and protocol IEC 60870-5-102 for meter reading.

These features make the unit applicable for various IoT projects and suitable for Industry 4.0 applications, including: gathering data from electrical meters; monitoring solar/photovoltaic systems; monitoring frequency drives used in pumping or other applications; temperature/humidity monitoring; and irrigation pump control and monitoring plus water metering.

The product can also be used to replace legacy 3G equipment, as it can be configured/customised to communicate to a legacy device previously connected to an older 3G modem.
