Industrial NMEA0183 to MQTT Broker converter with LTE, eSIM and VPN HD67C19-2-G43-E-VPN-B2

Industrial NMEA0183 to MQTT Broker converter with LTE, eSIM and VPN. HD67C19-2-G43-E-VPN-B2.

HD67C19-2-G43-E-VPN-B2 is an industrial communication converter designed to integrate devices using the NMEA0183 protocol over RS232 with modern MQTT Broker based IoT systems. The device is intended for marine, navigation, telemetry and industrial applications where secure, reliable and remote data transmission is required.

The G43-E-VPN version is equipped with an integrated LTE modem supporting both a physical SIM card and an embedded eSIM, combined with a built-in VPN service. This configuration ensures encrypted and secure communication with central IT systems, SCADA platforms and cloud infrastructures, even in locations without fixed Ethernet access.

By combining NMEA0183 (RS232) with an integrated MQTT Broker, the converter enables serial data mapping to MQTT topics and real-time data exchange between field devices and higher-level systems. Simultaneous support for Ethernet and LTE connectivity provides high flexibility for distributed and mobile installations.

Key features

• Conversion of NMEA0183 (RS232) data to MQTT Broker.
• Integrated VPN service for secure and encrypted communication.
• Ethernet RJ45, LTE SIM and eSIM connectivity.
• RS232 data rates up to 115200 bps.
• Support for 10/100 Base-T Autosensing MQTT communication.
