10-Foot USB to Null Modem RS232 Serial Adapter Cable with FTDI Chipset, COM Port Retention, and Level-4 ESD Protection for Network Equipment and Industrial Devices
The StarTech 1P10FFCN-USB-SERIAL is a 10-foot USB to serial adapter cable with built-in null modem crossover that adds an RS-232 DB9 serial port to any computer through USB-A. The integrated null modem wiring resolves DCE/DTE conflicts directly without requiring additional crossover cables or adapters, connecting to managed switches, routers, POS terminals, and industrial equipment that require null modem serial connections.
The FTDI FT232R chipset delivers reliable serial communication at baud rates up to 921.6Kbps with COM port retention that automatically reassigns the same COM port number when the adapter is reconnected or the system reboots. Level-4 ESD protection (15kV air/8kV contact), copper shielding for EMI/RFI resistance, and gold-plated connectors provide the durability required for daily use in network closets, server rooms, and field service environments.
Where the StarTech USB to Serial Adapter Fits
- Network administrators configuring managed switches and routers via console port where the built-in null modem crossover eliminates the need for a separate crossover cable, and COM retention maintains consistent port assignment across sessions for reliable scripted configuration and terminal access
- Point-of-sale and industrial environments connecting legacy RS232 equipment to modern computers where the 10-foot cable reaches between counters and terminals, FTDI chipset compatibility covers receipt printers, barcode scanners, and POS devices, and ESD protection guards against static damage in retail environments
- Field technicians servicing serial-connected equipment across multiple sites where the interchangeable DB9 screws and nuts accommodate both DTE and DCE device connectors, LED indicators confirm data transmission and USB enumeration at a glance, and cross-platform driver support covers Windows, macOS, ChromeOS, and Linux laptops
What the StarTech USB to Serial Adapter Delivers
- Built-In Null Modem Crossover: Integrated null modem wiring resolves DCE/DTE conflicts without additional crossover cables or adapters. Interchangeable DB9 screws and nuts accommodate both device types for secure, rattle-free connections.
- FTDI FT232R with COM Retention: Industry-standard FTDI chipset provides reliable serial communication up to 921.6Kbps with 128-byte RX and 256-byte TX FIFO buffers. COM port retention automatically reassigns the same COM port number after disconnection or reboot.
- Level-4 ESD Protection: 15kV air and 8kV contact discharge protection exceeds standard requirements for environments prone to static buildup. Copper shielding minimizes EMI/RFI interference, and gold-plated connectors enhance signal conductivity over the 10-foot cable run.
- Cross-Platform Compatibility: Drivers auto-install on Windows 7+, macOS 10.15+, ChromeOS, and Linux without manual configuration. Supports 7/8 data bits, 1/2 stop bits, and odd/even/mark/space/none parity modes for universal serial device compatibility.
- Real-Time LED Diagnostics: Dedicated Transmit, Receive, and USB enumeration LEDs provide instant visual confirmation of port activity and connection status, simplifying troubleshooting in server rooms and network closets without opening terminal software.
