Bridge Modbus TCP clients to serial RTU devices. Connect SCADA/HMI software to your serial devices over network.
Built-in Model Context Protocol server. Let AI assistants control your serial devices via TCP. 15 tools available.
Scan and read/write I2C/SPI devices. CAN bus frame capture and analysis with SLCAN protocol support.
Real-time data rate charts, oscilloscope waveform display, data logging to CSV with timestamps.
STM32 ISP and ESP32 serial flashing. XMODEM/YMODEM/ZMODEM file transfer with progress tracking.
SerialRUN includes a built-in MCP (Model Context Protocol) server that allows AI assistants to remotely control your serial devices.
// Connect AI to your serial device
const client = new MCPClient("127.0.0.1", 9527);
await client.call("connect", { port: "COM4", baud_rate: 115200 });
const response = await client.call("send_command", { command: "AT+RST" });All panels run as independent OS windows β drag, resize, and arrange freely
Each panel (Modbus, PLC, Log, etc.) is a separate OS window that can be moved anywhere on screen.
Protocol panels stay above the main window β never lose your tools behind the terminal.
Terminal toolbar adapts to window size β controls wrap automatically, nothing gets clipped.
