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
system.
