Industrial USB to Serial Converter

This WaveShare adapter connects USB hosts to RS232, RS485, RS422 and TTL serial devices using an original FT232RNL chip. It serves engineers, integrators and hobbyists who need reliable serial links for industrial equipment, automation gear or legacy hardware across Windows 11, 10, 8.1, 8, 7, Mac, Linux and Android platforms.

Isolation and Protection Limits

The onboard unibody power and digital isolation separates the USB side from the serial terminals without an external supply. Built-in TVS diodes, a self-recovery fuse and protection diodes suppress surge and transient spike voltages while providing over-current and over-voltage safeguards, but the adapter cannot protect against sustained over-voltage conditions beyond the suppressor ratings.

Pre-Installation Checks

Verify that your target device uses one of the supported RS232, RS485, RS422 or TTL interfaces and matches the required voltage levels. Confirm the host operating system appears in the supported list and that you have a free USB port. Ensure the mounting surface suits wall-mount or rail-mount brackets if a fixed industrial installation is planned.
