1.1 Introduction

This document is the EVM user’s guide for the THVD4421EVM, which provides a quick way to evaluate TI’s THVD4421EVM. The THVD4421 is among TI’s first RS-485 and RS-232 multiprotocol transceivers. This configuration allows for 2T2R RS-232 communication, half duplex RS-485 communication, full duplex RS-485 communication, and a loopback mode for RS-232 to allow for on chip diagnostic testing.
