Product information

Description

Add an RS-232 null modem serial port to a laptop or desktop using an available USB-A port. The 1 ft (30 cm) USB to Null Modem Serial Adapter Cable (FTDI chipset) provides an RS-232 DB-9 (female) serial connection that resolves DCE/DTE conflicts without the need for additional cross-wired cables or adapters.

Advantages

The cable includes interchangeable DB-9 nuts and slotted D-Sub thumbscrews for flexible mounting and compatibility with a range of serial peripherals. LED indicators show transmit, receive and USB enumeration status for straightforward diagnostics. Built with TPE jacket, copper shielding and gold-plated connectors, the adapter offers improved durability, reduced EMI/RFI and reliable signal conductivity. It also provides Level-4 ESD protection (15kV air, 8kV contact) for enhanced device safety.

Suitable for

  • Connecting legacy RS-232 serial devices (modems, instruments, industrial controllers) to modern computers
  • Resolving DTE/DCE pinout conflicts without additional null-modem adapters or special cables
  • Field service, diagnostics and troubleshooting where LED activity indicators are useful
  • Systems requiring USB-A to DB-9 connectivity on Windows, macOS, ChromeOS or Linux

Key specifications

  • Length: 1 ft (30 cm)
  • Connector 1: USB Type-A (male)
  • Connector 2: DB-9 RS-232 (female, null modem)
  • Chipset: FTDI
  • Compatibility: Windows 7 and newer, macOS 10.15+, ChromeOS, Linux (drivers auto-install on supported OS versions)
  • COM retention: preserves/reassigns COM port on reconnect or reboot
  • Construction: TPE jacket, copper shielding, gold-plated connectors
  • ESD protection: Level-4 (15 kV air, 8 kV contact)
  • Product colour: Black

How to use

Plug the USB Type-A end into an available USB-A port on the computer and connect the DB-9 female end to the serial device. Secure the DB-9 connection using the pre-installed/removable DB-9 nuts or install the included slotted D-Sub thumbscrews to match the serial peripheral or cable. Allow the operating system to install drivers automatically on supported versions; if necessary, install drivers provided by the manufacturer. Verify link and data activity using the adapter LEDs and check the assigned COM port in the operating system if required for your application.

Usage recommendations

For reliable operation, use on systems with available USB-A ports and supported OS versions. Route the cable to minimize exposure to strong electromagnetic sources and ensure thumbscrews or nuts are snug to maintain a secure DB-9 connection. If experiencing connectivity or COM assignment issues, reconnect the cable or reboot the system to allow COM retention to reassign the port.
