Intro Summary
Professional USB‑RS‑485 cable for Mitsubishi E700/A700/F700/A800/F800 inverters—ideal for programming, monitoring, and downloading with stable performance.
Product Overview
The DINV‑U4 cable is a dedicated USB‑to‑RS‑485 communication interface designed for Mitsubishi inverter models E700, A700, F700, A800, and F800 . Officially equivalent to Mitsubishi’s DINVU4 programming cable , it ensures reliable data transmission and consistent debugging and downloading performance. Built with quality connectors and robust shielding, this cable supports firmware updates, parameter setting, monitoring, and diagnostics through Mitsubishi software tools like FR Configurator2 .
How to Use
- Connect the RJ‑45 end directly to the inverter’s PU/COM port.
- Plug the USB Type‑A connector into your PC.
- Install Mitsubishi’s communication driver (e.g., FTDI-based).
- Launch FR Configurator2 or FX‑Configurator to detect the inverter via COM port.
- Download/upload parameters, monitor runtime data, or debug faults.
Practical tips: ensure correct COM port and baud rate, use shielded Cat‑5e cable for EMI protection, and always terminate RS‑485 networks properly .
