This article addresses USB touch monitor compatibility with serial comports.

We’re often asked if an Elo monitor with only USB touch capability can be used with a computer that only has RS-232 serial ports.

The answer is no—this is not possible. There are no adapters or converters that can bridge USB touch functionality to a serial-only connection.

This should not be confused with using a serial touch monitor on a USB port, which is possible. For that scenario, refer to the knowledge base article: Serial to USB Converters.
