Introduction

Overview

The Sealevel Systems equips the PC with 2 USB to RS-422/485 Asynchronous
serial ports providing a versatile interface for common serial needs. The
advantage of this product over more traditional approaches is that it does not
require opening the computer case, nor does it require resources such as I/O
ports or IRQ’s. It does require a system that supports USB both in terms of
hardware and operating system.
