Industrial NMEA0183 RS485 to MQTT Broker converter with LTE HD67C19-5-G43-B2

Industrial NMEA0183 RS485 to MQTT Broker converter with LTE. HD67C19-5-G43-B2.

HD67C19-5-G43-B2 is an industrial communication converter designed to integrate devices using the NMEA0183 protocol over RS485 with modern MQTT Broker based systems. The device is intended for marine, navigation, telemetry and industrial applications where reliable long-distance serial communication is required.

The use of the RS485 interface ensures high immunity to electromagnetic interference and stable operation in harsh industrial environments. The G43 version is equipped with an integrated LTE modem supporting a standard SIM card, allowing MQTT data transmission also in locations without fixed Ethernet infrastructure.

By combining NMEA0183 (RS485) with a built-in MQTT Broker, the converter enables mapping of serial data to MQTT topics and real-time publishing and subscription. Simultaneous support for Ethernet and LTE connectivity provides high flexibility for distributed and remote installations.

Key features

• Conversion of NMEA0183 (RS485) data to MQTT Broker.
• Ethernet RJ45 and LTE (SIM) connectivity.
• RS485 data rates up to 115200 bps.
• Support for 10/100 Base-T Autosensing MQTT communication.
• Galvanic isolation between Ethernet interface and power supply.
• Wide operating temperature range from -40°C to +85°C.
• Compact industrial B2 Modulbox enclosure for DIN rail mounting.

Device configuration is performed using dedicated software SW67C19, which allows configuration of RS485 parameters, MQTT Broker settings and data mapping. The software is available for download at: download SW67C19 software .
