HD67G04-2-G43-B2 RS232 to HTTP/REST Server converter with LTE

HD67G04-2-G43-B2 connects RS232 devices with HTTP/REST Server communication through Ethernet and SIM LTE.

HD67G04-2-G43-B2 is an industrial RS232 to HTTP/REST Server converter, designed to integrate devices communicating through RS232 with modern data exchange systems operating in an Ethernet network and through mobile connectivity. This model works well in telemetry applications, remote monitoring systems, automation installations, and projects where classic serial communication must be connected with network services.

The HD67G04-2-G43-B2 variant offers Ethernet and SIM LTE connectivity, which allows the device to operate both in a local industrial network and in distributed installations where remote data access is required. It is a practical solution for system integrators, machine builders, and maintenance teams that need to make field data available to higher-level systems without creating a complex intermediate infrastructure.

By operating as an HTTP/REST Server, the device can make serial data available in a structured form to applications, supervisory systems, and integration platforms. The manufacturer provides the possibility to define HTTP/REST communication parameters, serial line parameters, the list of clients communicating with the device, and communication endpoints, which makes it possible to adapt the converter precisely to the requirements of a specific application.

HD67G04-2-G43-B2 supports RS232 data rates up to 115200 bps and 10/100 Base-T Autosensing Ethernet communication. An additional advantage is the electrical isolation between Ethernet and power supply, which supports stable operation in industrial environments. The compact housing type B, mounting on a 35 mm DIN rail, and wide operating temperature range from -40°C to +85°C make this model suitable for demanding industrial installations.

In the G43 version, the manufacturer uses an LTE module with Micro-SIM support and an SMA Female antenna connector. The Ethernet port is used both for programming the device and for HTTP/REST communication, which simplifies commissioning and later service work. In practice, this model can act as a reliable bridge between RS232 devices and modern network-based applications.
