Industrial dual-port serial adapter

The GearMo GM-FTDI2X-M adds two DB9 RS-232 ports to a computer through a single USB 2.0 connection. It uses an FT2232H FTDI chipset that automatically creates the extra COM ports without manual configuration. The unit draws power from the USB bus so no external supply is required. Built-in 15 kV surge protection guards the converter and attached equipment.

Suited for legacy device integration

Engineers and technicians who need to connect serial modems, barcode scanners, CNC routers, GPS units or older PDAs will find the automatic handshake support and baud rates up to 921.600 bps convenient. The DIN-rail clips and surface-mount brackets allow secure cabinet installation. Users who require more than two serial ports or a different physical interface should consider alternative solutions.

Check host compatibility and cabling

Verify that the host system has an available USB 2.0 Type-A port and runs an operating system supported by the FTDI driver. Ensure the serial cables you plan to use are standard DB9 RS-232 types with the correct pin-out for each peripheral. Confirm that the mounting method matches the enclosure or panel where the adapter will be installed.

Questions about this item

Does my computer need a USB 2.0 port to use the GM-FTDI2X-M?

Yes, the converter connects through a USB 2.0 interface and draws power from that port.

Will the FT2232H chipset work with legacy RS-232 devices that only support lower baud rates?

The FT2232H chipset handles baud rates up to 921.600bps and automatically negotiates the speed required by older serial equipment.

How can I confirm both COM ports are active after plugging in the converter?

Open Device Manager; two new COM ports will appear and the RX/TX LEDs on the unit will flash during data transfer.
