StarTech.com 2ft/60cm 2-Port USB to Serial Adapter Cable, COM Retention, FTDI, DB9 RS232, Changeable DB9 Screws/Nuts, Windows/macOS/Linux

Add RS-232 serial communication support to USB-A enabled Data Terminal Equipment (DTE - e.g., desktop or laptop), using this 2ft (61cm) straight through 2-Port USB to Serial Adapter Cable.

Serial Port Expansion

The Dual-Port USB Serial Adapter adds two RS-232 serial DB/DE-9 (male) connectors to a desktop or laptop via a single USB Type-A port. Secure the adapter to a serial device, using pre-installed and removable slotted DB-9 nuts or install the included DB-9 thumbscrews for compatibility with other serial peripheral devices or cables.

LED Indicators

Data transmission and reception LED indicators for each port on the adapter provide real-time monitoring of port activity. The USB LED indicates when the adapter has successfully enumerated on the desktop or laptop. All the LEDs aid with diagnostics and troubleshooting.

Seamless Connectivity

The adapter is compatible with Windows, macOS, ChromeOS, and Linux. Drivers automatically install to Windows 7 and newer versions, macOS 10.15 and above, and Linux. The USB to RS-232 adapter features COM retention, which automatically reassigns the COM port value if the cable is disconnected and reconnected, or if the system is rebooted.

Built To Last

The rugged TPE construction and Level-4 ESD protection (15kV air and 8kV contact) enhance the reliability and longevity of the USB to Serial Adapter. Copper shielding minimizes Electromagnetic and Radio Frequency Interference (EMI and RFI). Gold-plated connectors enhance signal conductivity. The included mounting bracket allows the hub of the serial adapter to be mounted to a desired surface.
