HD67G03-2-G43-E-B2 RS232 to HTTP/REST client converter with LTE and eSIM

HD67G03-2-G43-E-B2 connects RS232 devices with HTTP/REST client communication through LAN, LTE, and eSIM.

HD67G03-2-G43-E-B2 is an industrial RS232 to HTTP/REST client converter designed to integrate devices communicating via RS232 with systems based on HTTP/REST. This model works well in applications where classic serial communication has to be connected with modern data exchange in a local network or through mobile connectivity.

The HD67G03-2-G43-E-B2 variant offers LAN, SIM LTE, and eSIM connectivity, which allows it to operate both in a local Ethernet network and in distributed installations where remote access to data is required. It is a practical solution for system integrators, machine builders, and maintenance teams that need to connect field devices with network services without building a complex intermediate infrastructure.

HD67G03-2-G43-E-B2 allows precise configuration of HTTP/REST communication parameters, serial line parameters, the list of servers, and communication endpoints. As a result, the converter can be adapted to a specific application, whether its task is to send measurement data, operating statuses, alarms, or process information to a higher-level system.

The device 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, DIN rail mounting, and wide operating temperature range from -40°C to +85°C make this model suitable for demanding installations.

The G43-E version uses an LTE module with support for Micro-SIM and eSIM, as well as an SMA Female connector for the antenna. This equipment increases deployment flexibility and helps create a stable connection in locations where wired communication is not sufficient or not available.
