P5H-152 – RS422/RS485 PHPoC IoT Gateway
P5H-152 is a programmable IoT gateway for RS422/RS485 serial devices, combining robust industrial serial connectivity with Ethernet networking. It runs PHPoC (PHP on Chip) scripts for custom edge logic and includes a built-in web server so you can implement browser-based monitoring and control.
Key features
- • RS422/RS485 gateway for sensors and industrial devices (ideal for multi-drop networks and long serial runs).
- • Programmable with PHPoC scripts for data transformation, filtering, and protocol bridging.
- • Built-in web server and user-customized webpages for monitoring and control via browser.
- • Development and configuration through USB using PHPoC Debugger.
Built for industrial serial networks (RS422/RS485)
P5H-152 connects RS422/RS485 devices to Ethernet and lets you handle data at the edge—perfect for meters, controllers, building automation, and industrial sensors where reliable differential serial communication is preferred.
- • Select RS422 or RS485 depending on your device and topology.
- • Great foundation for serial→TCP, serial→HTTP/HTTPS, and serial→MQTT gateway behaviors via scripting.
Web interface + real-time control
Use the built-in web server to host your custom pages and implement monitoring/control features directly on the device. For real-time interaction, WebSocket support enables fast updates without constant page refresh.
- • Browser-based access for configuration, monitoring, and control.
- • Secure networking building blocks (TLS) for production deployments.
