Introduction

Thank you for purchasing a StarTech.com RS-422/RS-485 isolated serial PCI card. Now
you can add two (PCI2S422ISO) or four (PCI4S422ISO) RS-422/RS-485 serial ports to
your system. Dip switches located on the card let you select between RS-422 and RS-485
formats for each port, depending on the application you need. The DB9 connectors let
you connect many types of serial peripherals, like networking devices, high speed
modems, monitoring equipment, long distance communication devices and printers.

Features

• Adds two or four isolated RS-422/RS-485 serial ports to your system

• Uses a dip switch design to allow you to select either RS-422 or RS-485 serial interface

formats depending upon your application

• Provides data transfer rates of up to 115.2 Kbits/sec per port 

• Complies with PCI version 2.2 

• Uses 32 Byte FIFO to minimize data loss and optimize host efficiency and data 

integrity

• Uses Plug & Play installation 

Before You Begin

To ensure a quick and easy device installation, please read through this section carefully
