Introduction

Thank you for purchasing a StarTech.com RS-232 ISA serial card. This product allows

you to add between one or two serial ports to your computer (varies by model), using an

easy jumper-driven configuration. An excellent choice to maximize your investment in

existing serial-based technology or integrated custom solutions.

Features

•Fast data transfer rates: up to 460 Kbits/sec.

•Easy installation using a fully Plug and Play configuration

•Backed by StarTech.com’s lifetime warranty and free technical support

Before You Begin

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

before attempting to install the card.

WARNING! ISA cards, like all computer equipment, can be severely damaged by static

electricity. Be sure that you are properly grounded before opening your computer case or

touching your ISA card. StarTech.com recommends that you wear an anti-static strap

when installing any computer component. If an anti-static strap is unavailable, discharge

yourself of any static electricity build-up by touching a large grounded metal surface

(such as the computer case) for several seconds. Also be careful to handle the ISA card

by its edges and not the gold connectors.

System Requirements

•An IBM compatible computer with an available ISA slot

Contents

This package should contain:

•1x ISA serial card

•1x Instruction Manual

Installation

This section will guide you through the installation of your ISA card and the related

software. Please read through the instructions carefully and complete each step in the

order listed.

Installing the Card

1. Make sure that your system is unplugged and you are grounded.

2. Remove the cover of your system (see your computer's user manual for details, if

necessary) and gently turn your computer onto its side.

3. Locate an empty ISA slot and remove the metal plate that covers the rear bracket.

You may need a Phillips screwdriver to perform this step. Retain the screw! You will

need it to secure the card later.

4. Gently insert the card into the empty slot, making sure it is firmly seated.

5. Secure the card in place using the screw you removed in Step 3.

6. Put the computer case back on.

Setting the Jumpers

There are three sets of jumpers that can be configured on your card: reference transfer

rate, COM address, and IRQ address.

Reference Transfer Rate

There are three possible transfer rate settings (labeled 1, 2, and 4) for the COM port(s).

The phrase “reference” refers to the maximum possible transfer rate between the port

and your device, and my not be the actual transfer speed under operational conditions.

Each pin corresponds to the following transfer rate:

Instruction Manual

Set the transfer rate for each port by setting the jumpers according to the following

example:

In the example above, Port A has been set to 460.8 Kbits/sec and Port B has been set to

230.4 Kbits/sec. For the single port model, you will only have the pins and jumpers

to configure Port A.

COM Address

There are seven possible COM address settings (labeled 1 through 7). For the single

port model, you will have a jumper to configure port A only.

1. Find an available COM Address on your system. Consult the user manual that came

with your OS for instructions, if necessary. This card supports COM Addresses

1 through 7.

2. Set the COM Address for each port by placing the jumpers according to the following

example:

In the example above, Port A is set to COM 1 and Port B is set to COM 2.

The base addresses are as follows:
