Introduction

The PCI2S422ISO 2 Port PCI RS422 RS485 DB9 Serial Adapter Card adds two isolated

serial (DB9) ports to a PCI-enabled computer, providing a cost-eective way to connect

your RS422 or RS485 serial devices to a computer doesn’t oer native serial support, or

adding more ports to a computer that does.

To ensure eective data transmission over long distances, including electrically noisy

environments, the card’s ports feature optical isolation.

Ensuring a reliable RS422 or RS485 connection with a broad range of serial devices

including printers, touch screen monitors and more, the adapter card is suitable

for industrial applications and compatible with a broad range of operating systems

including Windows, DOS, Linux and Unix based platforms.

Backed by a StarTech.com lifetime warranty and free lifetime technical support.

• An open 5V PCI slot

Instruction Manual

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. If you are installing two cards in the same system, you must dierentiate 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.

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

necessary) and gently turn your computer onto its side.

4. 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.

5. Gently insert the card into the empty slot, making sure it is rmly seated.

6. Secure the card in place using the screw you removed in Step 3 and put your

computer case back on.

7. Turn the computer on.

Instruction Manual

Driver Installation

Note: Depending on your operating system and the conguration of your system, the

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

Windows XP/2000/Vista

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 conrmed. In Windows

2000, the driver will be installed automatically.

Instruction Manual

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 conict 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.

Instruction Manual

DOS

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

card Number 1 (with the jumper ON) rst.

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 les 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.

Instruction Manual

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 Denitions

Card Number Device Name

1 tty81?

2 tty82?

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

Instruction Manual

I/O Port Number Denitions

Port Number Device Name

A tty8?a

B tty8?b

C tty8?c

D tty8?d

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 le for the Linux system and the source

le must be located in the /usr/src/linux directory. If your source le is in a dierent

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.
