USB to RS422/RS485 converter with FTDI chip

This cable connects RS422 or RS485 serial devices to a USB port on a laptop or desktop. The FT232 chipset handles the conversion and supports both half-duplex and full-duplex modes. It is intended for industrial equipment, legacy instruments or automation gear that still use serial interfaces.

Driver installation and common issues

Windows 11, 10, 8, 7 and Mac OS recognise the device without an external power supply. The FTDI driver usually installs automatically, but some systems need a manual download from the chip vendor. If the COM port does not appear, check Device Manager for a missing or unsigned driver and disable any power-saving setting on the USB root hub.

Check your device and wiring before ordering

Verify that your equipment uses RS422 or RS485 signalling, not plain RS232, because the electrical levels are different. Confirm the connector gender and pin-out on the serial side match your cable or terminal block. The adapter provides 600 W surge protection and 15 KV ESD isolation on the signal pins, so ensure your wiring does not exceed those ratings.
