USB 2.0 RS-232 adapter for legacy serial gear

This 30 cm cable adds a DB9 serial port to any computer with a USB-A 2.0 socket. The FTDI FT232R chipset handles up to 921.6 Kbps with 128 byte RX and 256 byte TX FIFOs. Drivers load automatically on Windows 7 and later, macOS 10.15 plus, ChromeOS and Linux, and COM retention keeps the port assignment after a reboot or reconnect.

Replaces built-in COM ports and bulky PCI cards

Use it when a motherboard lacks a native serial header or when a full-height expansion card is impractical. The short 1-foot length keeps the link tidy on a bench, in a rack or on a mobile cart. The jump is worth it whenever you need a reliable serial link without opening the case or hunting for a legacy header.

Fits a USB-A port and secures with swappable

Pre-installed DB9 nuts hold the adapter to DTE equipment; the included screws swap in for DCE cables or peripherals. Gold-plated contacts and Level-4 ESD protection at 15 kV air and 8 kV contact guard the port in industrial environments. Shielded copper braid reduces EMI while the moulded TPE body survives -40 °C to 80 °C operation.
