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

HD67G04-2-G43-VPN-B2 connects RS232 devices with HTTP/REST Server communication via Ethernet, SIM LTE and VPN service.

HD67G04-2-G43-VPN-B2 is an industrial ADFweb converter designed to connect RS232 devices with systems and applications based on HTTP/REST Server communication. This model is intended for installations where traditional serial communication must be integrated with modern Ethernet infrastructure and remote mobile connectivity in industrial environments.

The HD67G04-2-G43-VPN-B2 variant offers LAN + SIM LTE connectivity together with VPN Service, making it a strong choice for applications that require both data exchange between RS232 devices and HTTP/REST Server environments and secure remote access to distributed systems. It is well suited for automation integrators, machine builders, telemetry projects and industrial installations operating across multiple locations.

The device is designed for industrial use and offers a wide power supply range of 8..24V AC / 12..35V DC, an operating temperature range of -40°C to +85°C, compact housing type B and 35 mm DIN rail mounting. An additional advantage is the electrical isolation between Ethernet and power supply, which supports reliable integration in control cabinets and demanding industrial applications.

Configuration is carried out with SW67G04, which allows the user to define HTTP/REST Server parameters, configure the serial line, manage clients and endpoints, and update the device. This gives the installer the flexibility to adapt the converter precisely to the needs of a specific industrial application. Based on the manual, this variant belongs to the Serial / HTTP/REST Server family and the G43 version includes LTE connectivity, while the VPN version adds VPN service support. :contentReference[oaicite:0]{index=0}
