    The StarTech 1P6FFCN-USB-SERIAL is a 6.6-foot USB-A-to-DB9 null modem serial adapter cable for connecting a computer to compatible RS-232 equipment, making it suitable for technicians and users working with serial devices.

    Recommended For

    • IT and network technicians who need to connect a USB-A laptop to RS-232 equipment that requires null-modem wiring, such as for configuration or troubleshooting.
    • Automation and industrial service technicians who work with RS-232 devices and want a single USB-to-null-modem cable instead of carrying a separate serial adapter and crossover cable.
    • Technicians who need to keep a serial device a short distance from their computer; the 6.6-foot cable provides more reach than a compact adapter.
    • Support staff working across Windows, macOS, ChromeOS, or Linux systems who need a USB-A connection to an RS-232 device and value COM-port retention and activity LEDs for troubleshooting.
