USB to RS232 Serial Adapter — FTDI Chipset DIKWAN · SERIAL INTERFACE HARDWARE DATASHEET REV. 06FT/FTDI USB 2.0 → RS232 Serial, revived
for a USB world.
A genuine FTDI-chipset adapter that brings a full female DB9 serial port to any USB-A host — for the routers, PLCs, POS terminals, and lab gear that still speak RS232.

Runs on the FT232 chip, not a clone — the driver auto-installs on Windows, macOS, and Linux and holds a stable COM port through sleep and reboot.
02 — CONTACTS Gold-plated connectors
Both the USB-A plug and DB9 pins carry a gold-plated finish for corrosion resistance and a cleaner, lower-noise electrical connection.
03 — HOUSING Reinforced port shell
A molded housing with thumbscrew studs on the DB9 end locks the cable to your equipment so it won't work loose in a rack or under a desk.
04 — REACH 6 ft of working room
Long enough to route from a laptop or tower to a wall-mounted router, modem, or control panel without an extension.
05 — COMPATIBILITY Full RS232 signaling
Supports the handshake lines legacy serial devices expect, not just TX/RX — so console and modem-style connections behave correctly.
06 — SETUP Plug and play
No external power, no configuration utility to run first. Connect it, let the driver install, and the port shows up ready to use.
Pin reference DB9 female pinout
Standard RS232 assignment, so the adapter drops into existing null-modem, console, and instrument cabling without rewiring.
