  • Adds one RS-232 serial port via high-performance FTDI chipset
  • 25 kV ESD and 600 W surge protection guards connected equipment

One RS-232 port for modern hosts

The GearMo GM-FTDI1X-M adds a single standard RS-232 serial port to any laptop or desktop using a high-performance FTDI chipset. It targets engineers and technicians who must keep legacy industrial, medical or point-of-sale equipment talking to current computers without internal expansion cards.

Driver install then plug in

Windows 7 through 11, Linux and macOS 10.x recognise the adapter automatically and assign a COM port that is retained after accidental disconnects. The six-foot cable reaches most bench setups, but the DB-9 connector is fixed so gender changers or null-modem cables may still be required for some instruments.

Up to 921.6 Kbps with 25 kV isolation

The 16-byte hardware buffer handles bursty traffic from GPS units, modems or barcode scanners at baud rates up to 921.6 Kbps. The iCoupler isolation and 600 W surge rating protect the host from industrial transients, yet the single port cannot serve multi-drop networks or simultaneous devices without an additional hub.

The adapter creates a new COM port in Device Manager and the Power, RX, and TX LEDs light up when data moves.

What comes in the box with the GM-FTDI1X-M and what must I buy separately?

The package includes the converter with a 6ft cable, surface-mount and DIN-Rail brackets, and driver media; no extra power supply is required.

Which version of this converter should I choose for my operating system?

The single GM-FTDI1X-M model supports Windows 7, 8, 10, 11, Linux, and Mac OS 10.X, so one version covers all listed platforms.
