StarTech 2m USB To Serial Adapter Cable

Expand a laptop or desktop with a serial RS232 port via a free USB-A port.

Enhance the serial RS-232 communication of USB-A capable data terminal equipment (DTE, e.g., desktop or laptop) with this 2-meter USB-to-serial adapter cable.

The USB-serial adapter adds a serial RS-232 DB/DE-9 (male) port to a desktop or laptop through a USB Type-A port. Attach the adapter to a serial device using the pre-installed and removable slotted D-Sub thumb screws, or install the included DB-9 nuts for compatibility with other serial peripherals or cables.

The LED indicators for data transmission and reception on the adapter allow for real-time monitoring of connection activity. The USB LED indicates when the adapter has successfully registered with the desktop or laptop. All LEDs assist in diagnostics and troubleshooting.

The adapter is compatible with Windows, macOS, ChromeOS, and Linux. Drivers are automatically installed for Windows 7 and newer versions, macOS 10.15 and higher, as well as Linux. The USB to RS-232 adapter features COM retention, which automatically reassigns the COM port value when the cable is unplugged and reconnected or when the system is restarted.

The robust TPE construction and level 4 ESD protection (15 kV air and 8 kV contact) enhance the reliability and durability of the USB to serial adapter. The copper shielding minimizes electromagnetic and radio frequency interference (EMI and RFI). Gold-plated connectors improve signal conductivity.
