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

Industrial NMEA0183 (RS232) to MQTT Broker Converter with LTE SIM and eSIM

HD67C19-2-G43-E-B2 is an industrial communication converter designed to integrate devices using the NMEA0183 protocol over RS232 into modern MQTT Broker-based IoT architectures. The device is dedicated to marine, navigation, telemetry and industrial applications where reliable and continuous transmission of serial data to cloud platforms, SCADA systems and monitoring solutions is required.

The G43-E variant is equipped with an integrated LTE modem supporting both a standard SIM card and an embedded eSIM. This dual cellular capability increases communication reliability, enables redundancy at the connectivity level and allows flexible deployment in locations without fixed Ethernet infrastructure. The converter supports both LAN and cellular connectivity, ensuring high availability of MQTT data transmission.

By combining NMEA0183 (RS232) communication with a fully integrated MQTT Broker, the device enables efficient mapping of serial data to MQTT topics, as well as publishing and subscribing messages between field devices, SCADA systems and cloud-based IoT platforms.

Key features

• Conversion of NMEA0183 (RS232) data to MQTT Broker.
• Ethernet RJ45, LTE SIM and eSIM connectivity.
• RS232 data rates up to 115200 bps.
• Support for 10/100 Base-T Autosensing for MQTT communication.
• Galvanic isolation between Ethernet interface and power supply.
• Wide operating temperature range from -40°C to +85°C.
