HD67G03-2-G43-B2 RS232 to HTTP/REST Client converter with LAN and SIM LTE

HD67G03-2-G43-B2 integrates RS232 devices with HTTP/REST Client via LAN and SIM LTE.

HD67G03-2-G43-B2 is an industrial RS232 / HTTP/REST Client - Converter designed to integrate devices communicating via RS232 with modern data exchange systems based on HTTP/REST Client. This version is intended for applications where traditional serial communication must be connected to network infrastructure, cloud platforms, API servers, telemetry systems, or dedicated web services.

The HD67G03-2-G43-B2 version offers LAN + SIM LTE connectivity, which means it can operate both in a local Ethernet network and in installations where data transmission requires mobile access. This makes it a practical solution for system integrators, machine builders, monitoring systems, and automation applications that need to transfer RS232 data to web-based environments without building a complex communication architecture.

A key advantage of HD67G03-2-G43-B2 is the possibility to configure serial line parameters, HTTP/REST Client settings, the list of servers, and communication endpoints. In practice, this allows the converter to be precisely adapted to a specific application, whether the device has to send measurement data, operating statuses, alarms, or integrate with an external API based on web-oriented data exchange.

The device supports RS232 data rates up to 115200 bps and 10/100 Base-T Autosensing Ethernet. Its compact housing type B, DIN rail mounting, terminal block connectors, and wide operating temperature range from -40 to +85°C make this converter suitable for demanding industrial environments, control cabinets, distributed systems, and field installations.
