Product information

Description

The StarTech.com USB to Null Modem Serial Adapter Cable (2 m) adds an RS-232 DB9 (female) serial port to a laptop or desktop through an available USB Type-A port. Equipped with an FTDI chipset, the adapter provides null modem (DCE-to-DCE) support so you can resolve DCE/DTE conflicts without additional cross-wired cables or adapters. The 2-meter cable includes removable slotted D-Sub thumbscrews and a set of DB-9 nuts for secure attachment to serial devices and compatibility with a variety of peripheral cables.

Advantages

This USB to RS-232 adapter offers LED indicators for transmit, receive and USB status to aid with real-time monitoring and troubleshooting. It supports automatic driver installation on Windows 7 and newer, macOS 10.15+ and many Linux distributions, and provides COM port retention to preserve the assigned COM value after reconnection or reboot. The cable is built with rugged TPE housing, gold-plated connectors and copper shielding for improved signal conductivity and reduced EMI/RFI. It also includes Level-4 ESD protection (15 kV air, 8 kV contact) to enhance durability.

Suitable for

  • Connecting legacy RS-232 equipment (modems, industrial controllers, lab instruments) to modern PCs
  • Resolving DCE/DTE serial communication conflicts without external null-modem adapters
  • Field service, diagnostics and development that require reliable serial console access

How to use

Plug the USB Type-A connector into an available USB port on your computer and attach the DB-9 connector to the serial device. Use the pre-installed slotted D-Sub thumbscrews or the included DB-9 nuts to secure the connection. If drivers do not install automatically, download the appropriate FTDI drivers for your operating system from the manufacturer. After installation the adapter will enumerate as a COM port; use your serial terminal or application to select the assigned COM port and configure serial settings (baud rate, parity, data bits, stop bits) as required by the connected device.
