USB-to-COM Port Adapter Board User Guide

General Description

The USBTO232 is an adapter board that converts a PC’s USB port into a standard COM port. A COM port is also known as the standard serial port that uses Recommended Standard 232 (RS-232).

The USBTO232 is included with selected Maxim EV kits and EV systems that were originally designed for the PC COM port and later updated to also support the USB port. Data sheets for EV kits and EV systems that can use the USBTO232 have been updated to reflect compatibility and also provide ordering information. Use of the USBTO232 in applications other than those EV kits specified by Maxim is not supported.

Important: Before using the USBTO232, see the Quick Start section of this data sheet to correctly install the USB driver for the appropriate Windows® operating system.
