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

before attempting to install the device.

Requirements

•Acomputer running Windows XP/2000/Me/NT/98/95, DOS, Linux or UNIX SCO

Open Server

•An open 5V PCI slot

Contents

•1x Isolated serial card

•1x Expansion cable with DB9 connectors (PCI4S422ISO only)

•Driver disks for Windows, Linux, and Unix

Note: Depending on the driver version, you may also see the PCI2S422ISO referred to as

the P422I or the PCIPORT on the driver disk. The PCI4S422ISO may be referred to as the

P485 or the the PCIPORT card.

Installation

Note: In one system, you can install two of these serial cards. Follow the instructions

below to designate each card as either card number 1 or card number 2. Install the cards

one at a time, starting with the card you want to be designated number 1.

Installing the Card

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

2. PCI2S422ISO: If you are installing two cards in the same system, you must

differentiate between the cards by using the dip switch on the card. You use dip

switch 1 and 2 to set the card number. When both dip switch 1 and 2 are in the ON

position, the card will be designated card number 1. When dip switch 1 is OFF and

dip switch 2 is ON, the card will be designated card number 2.

You use dip switch 3 and 4 to set each port to either RS-422 or RS-485 mode. Dip

switch 3 corresponds with Port A (marked on the card), dip switch 4 corresponds

with Port B. When the dip switch is in the ON position, the port will operate in RS-

422 mode. When the dip switch is in the OFF position, the port will operate in RS-485

mode.

PCI4S422ISO: If you are installing two cards in the same system, you must

differentiate between the two cards by using the JP1 jumper (located near the end

of the card). The card with the jumper ON will be card number 1. The card with the

jumper OFF will be card number 2.

Configure each port (labeled A to D) to be either an RS-422 or an RS-485 port using

the dip switches located on the card. When the dip switch is in the upper or On

position, that port will operate in RS-422 mode. When in the lower or Off position,

the port will operate in RS-485 mode.

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 PCI slot (usually white in colour) and remove the metal plate that

covers the rear bracket. You may need a Phillips screwdriver to perform this step.

Hang on to 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 and put your

computer case back on.

6. PCI4S422ISO only: Plug the 37-pin end of the serial cable into the port on the card.

7. Turn the computer on.

Driver Installation

Note: Depending on your operating system and the configuration of your system, the

instructions below may not be identical to what you see on your screen.

Windows

Windows XP/2000

Once you turn your computer on after installing the card, Windows will automatically

detect the new hardware. Follow the onscreen prompts and direct Windows to the

Win2000 folder on the driver disk (Windows 2000 and Windows XP use the same driver).

Notes:

•To change the COM port number: Windows will automatically assign the card a

COM port number. If you need to specify another port number, you can use the setup

utility included with the driver. Go to: Control Panel/System/Hardware/Device

Manager/Multi-Port Serial Adapter/Setup. From here you will be able to set the

target value.

•Each serial card needs an open IRQ for Plug and Play function.

•In Windows XP, the driver for each port will be installed and confirmed. In Windows

2000, the driver will be installed automatically.

Windows NT

Before you begin the installation, make sure you are logged in as a user with

administrative privileges.

1. Start the Control Panel applet by double-clicking on its icon in the Program Managers

main group.

2. Double-click the Network icon to bring up the Network Control Panel applet.

3. Select Add Adapter. A list of possible adapters will be displayed. Select “Other:

Requires disk from manufacturer.”

4. When prompted for the path, specify the location of the driver for the card you

installed. Depending on your version of the driver disk, the drivers for the

PCI2S422ISO may be found in the P220/NT4 folder. The drivers for the

PCI4S422ISO may be found in the P584/NT4 folder.

5. Follow the onscreen prompts to complete installation. Make sure that the COM port

number does not conflict with any other devices in your system.

6. Use the “Binding” function to make more serial ports available. If you do not perform

a binding function, you may not have an extra COM port available in your next boot

procedure.

Notes:

•When installing two cards in the same system, the card with the jumper ON will be

assigned the lower COM port number. The card with the jumper OFF will have the

higher COM port number.

Windows Me/98/95

Once you turn your computer on after installing the card, Windows will automatically

detect the new hardware. Follow the onscreen prompts and direct Windows to the Win95

folder on the driver disk (Windows Me, 98, and 95 use the same driver).

Notes:

•After you install the driver, you may get another message saying that new hardware

has been found. You do not need to install the driver again.

•Each serial card needs an open IRQ for Plug and Play function.

•In Windows 98, you need to assign the card to COM 5 or higher, because COM 3/4

has been reserved for a legacy COM port.

DOS

When installing multiple cards in DOS, it is important to install the card designated card

Number 1 (with the jumper ON) first.

1. Change your active directory to the target directory:

ex: c:\RAYON

2. Insert the driver disk into the disk drive and copy the DOS files from the driver

diskette:

ex: xcopy /s/e/v a:\DOS\*.*

3. Run the driver installation command:

ex: c:\rayon\pciport

4. The cards will now be installed in your system. Each card will show the card number

in the system (for the application to specify the target card and target port), the card

model, the card jumper setting (for card number 1 or 2), the IRQ assigned, and the

COM port number for the card.

You may see the following error messages:

•PCIPORT already installed. This means the driver has already been installed.

•Please check the “JP1”. This means that both cards in the system have their jumpers

ON or OFF.

•PCIPORT not in system. There is no card in the PCI slot.

Notes:

•The driver function call description can be found on the DOS driver diskette. There is

also a DEMO program for the user to modify to meet their target application

program.

LINUX

1. Login as super-user (SU) or root.

2. Change your directory to root and copy the driver diskette to the system:

# cd /

# tar xvf /dev/fd0

3. Change the directory to /etc/pciport and run the Install command:

# cd /etc/rayon

# ./Install

4. Follow the prompts to perform the following:

• Choose your card type

• Choose your Linux kernel version

• Rebuild your system

• Exit and reboot with new settings

The device name will be /dev/tty8[1--2] [a--h]

Card Definitions

Note: Card 1 is the card with the jumper ON.

I/O Port Number Definitions

For example, the device named /dev/tty82b is the device plugged into port B on card

Number 2.

Notes:

•The above installation procedure installs a module type driver. If you can not install

the driver successfully, you may need to use a kernel type driver. With kernel type

drivers, you may need to have the full source file for the Linux system and the source

file must be located in the /usr/src/linux directory. If your source file is in a different

location, you must move it or link it to the usr/src/linux directory.

•Each serial card needs an open IRQ for Plug and Play function.
