Industrial USB-QC30R2-V3.1 PLC Programming Cable

Industrial USB-QC30R2-V3.1 PLC Programming Cable is a USB-to-RS232 programming lead designed to connect a Windows PC to Mitsubishi MELSEC Q Series PLCs for programming and configuration. Made to present as a virtual COM port via an FTDI-based interface, it lets GX Developer or GX Works2 communicate with a Q Series CPU over USB without replacing legacy software workflows. The V3.1 variant is available in gold-plated connection configurations and includes isolation-type options to meet electrical safety requirements in demanding industrial environments. Key features include gold-plated contacts for corrosion resistance and reliable signal integrity, and the ability to support standard Mitsubishi programming tasks such as uploading and downloading ladder logic, configuring PLC parameters, and monitoring device status through a familiar PC-based workflow. This cable is specifically intended for Q Series PLCs and is commonly documented in Mitsubishi literature and third-party catalogs as the USB programming solution for PC-based programming and diagnostics, providing a straightforward bridge between modern laptops and traditional PLC development tools.
