Industrial NMEA0183 to MQTT Broker converter with LTE and VPN HD67C19-2

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

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

The G43-VPN version is equipped with an integrated LTE modem supporting a SIM card and a built-in VPN service. This allows secure, encrypted communication with central IT systems, SCADA platforms and cloud-based IoT infrastructures, even in locations without fixed Ethernet access.

By combining NMEA0183 (RS232) with an integrated MQTT Broker, the converter enables mapping of serial data to MQTT topics and real-time publishing and subscription. The device supports simultaneous Ethernet and LTE connectivity, ensuring high flexibility in distributed and remote installations.

Key features

• Conversion of NMEA0183 (RS232) data to MQTT Broker.
• Integrated VPN service for secure data transmission.
• Ethernet RJ45 and LTE (SIM) connectivity.
• RS232 data rates up to 115200 bps.
• 10/100 Base-T Autosensing support for MQTT communication.
• Galvanic isolation between Ethernet interface and power supply.
• Wide operating temperature range from -40°C to +85°C.
• Industrial B2 Modulbox enclosure for DIN rail mounting.

Device configuration is performed using dedicated software SW67C19, which allows configuration of RS232 parameters, MQTT Broker settings, VPN connection and data mapping. The software is available for download at: download SW67C19 software .
