Tera Grand USB 2.0 to RS232 Serial DB9 6' Adapter Cable

SKU CH-KB7V-2H8B8

Converts a USB 2.0 port to a 9-pin RS-232 serial DB9 connection using an FTDI chipset for speeds up to 230,400 bps

  • USB 2.0 port becomes a DB9 serial link
  • FTDI chipset delivers reliable 230 400 bps throughput
  • Works with Windows 10 back to 98 plus Linux and Mac
  • Female jack nuts give a secure screw-on connection
  • Six-foot cable reaches equipment without strain

USB-to-serial adapter for legacy devices

This cable converts a USB 2.0 port into a 9-pin male RS-232 serial connection. It targets users who need to link modern computers with modems, industrial equipment, POS terminals, or older serial printers.

FTDI chipset enables 230400 bps throughput

The built-in FTDI chipset drives the link up to 230400 bps and supports Windows 10, 8, 7, Vista, XP, 2000, 98, Linux and Mac. Driver updates must be downloaded from the manufacturer's website because the bundled driver is not current.

Plug-and-play after driver install

Installation requires downloading the latest driver before connecting the cable. The 6-foot length and female jack nuts give secure mounting, but the adapter lacks isolation, so it is not suited for electrically noisy industrial environments.

Questions about this item

What does the 230400 bps rating mean for actual serial-device communication?

The adapter can sustain up to 230400 bits per second over the RS-232 link, so high-speed modems, POS terminals or data-loggers run at their native rate without bottlenecks.

How does the USB 2.0 interface affect the maximum throughput?

The USB 2.0 connection provides ample bandwidth for the 230400 bps serial stream, so the port speed is limited by the FTDI chipset rather than the USB bus.

What physical mounting does the DB9 end need?

The 9-pin male DB9 connector has female hex jack nuts that accept standard RS-232 cable thumbscrews for a secure panel or bracket mount.
