HD67G04-2-B2 connects RS232 devices with HTTP/REST Server communication in Ethernet networks.
HD67G04-2-B2 is an industrial RS232 to HTTP/REST Server converter designed to integrate devices communicating through RS232 with modern data exchange systems based on HTTP/REST. This model works well in applications where classic serial communication must be connected with an Ethernet network and with higher-level systems using web-based services.
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. This makes it a practical solution for system integrators, machine builders, and maintenance teams that want to connect field devices with a modern communication environment without adding unnecessary intermediate components.
HD67G04-2-B2 allows precise configuration of HTTP/REST parameters, serial line parameters, the list of HTTP/REST clients communicating with the device, and communication endpoints. As a result, the converter can be adapted to a specific application, whether its task is to expose measurement data, operating states, alarms, or other 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, 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.
The Ethernet port is used both for programming the device and for HTTP/REST communication, which simplifies commissioning and later service work. In practice, HD67G04-2-B2 can act as a reliable bridge between serial devices and network-based applications, making it easier to integrate legacy equipment into a newer communication architecture.
