Hardware Installation
REMEMBER: the same COM port address or IRQ
setting CANNOT be used by more than one port in
your system. Each port assignment must be unique,
or a conflict will result and your connected device will
not work or communicate reliably.

Default COM Port,IRQ, and Baud Rate Jumper Settings
Serial Port 1 (SIO1) is a standard DB-9 (9-pin) connector
mounted on the card. It is factory set as C O M 1 with base
I/O address 3F8h
3F8h,IRQ4
IRQ4, and baud rate 115200.
Serial Port 2 (SIO2) is a standard DB-25 (25-pin) connector
mounted on the card. It is factory set as C O M 2 with base
2F8h,IRQ3
IRQ3, and baud rate 115200.
I/O address 2F8h
Serial Port 3 is mounted on a connector bracket and
connects to the SIO3 (10-pin connector) on the card via a
ribbon cable. It requires the I/O Expander 4S Upgrade Kit.
Serial Port 4 is mounted on a connector bracket and
connects to the SIO4 (10-pin connector) on the card via a
ribbon cable. It requires the I/O Expander 4S Upgrade Kit.

If any of these conflict with your current configuration, refer
to the following for another option.
NOTE:
Use jumper block S1 and S2 to configure the
COM port address for Serial Port 1 and 2
respectively. Use jumper block S3 and S4 to
configure the COM port address for optional
Serial Port 3 and 4 respectively.
The basic architecture for the PC provides for four COM
ports: COM1-COM4. However, as computer technology
and applications continue to evolve, more types of devices
have become available to expand your system’s capabilities...
resulting in a potential shortage of available system resources!
One of the advantages of your I/O Expander 4S is the
flexibility it offers by supporting COM1 through COM12.
IMPORTANT: Make sure the device or application software you
plan to use also supports an extended COM port assignment.

3-2.3 Interrupt Request (IRQ) Selection
Serial Port 1 is factory set as IRQ4
Serial Port 2 is factory set as IRQ3
If this conflicts with your current configuration, refer to the
following for another option.
NOTE:
Use jumper block S1_IRQ and S2_IRQ to configure
the IRQ setting for Serial Port 1 and 2 respectively.
Use jumper block S3_IRQ and S4_IRQ to configure
theIRQ setting for optional Serial Port 3 and 4.
Currently AT/Pentium computers support 16 interrupt
channels; however, not all are available to you. Some are
reserved for system use (IRQ 0, 1, 2, 8, 13) and others have
been used for standard installed devices such as mouse, fax/
modem, printer, sound card, floppy drive, etc., leaving only
the high IRQs (IRQ10 and above) for further expansion. Your
I/O Expander 4S allows for maximum expansion and
flexibility by supporting both low and high level IRQs.

3-3 Installing Your I/O Expander 4S
After you have verified the jumper settings on your I/O
Expander 4S, proceed with the following instructions to
install it in your computer. General instructions are given
since the design of computer cases varies. Refer to your
computer’s reference manual whenever in doubt.
1. Turn OFF the power to your computer and any other
connected peripheral devices. Follow the precautions
for static electricity discharge.
WARNING: STATIC ELECTRICITY DISCHARGE
may permanently damage your system. In order to
avoid possible static electricity discharge during
installation procedures, please follow the guidelines
below:
• Discharge any static electricity build up in your
body by touching a large grounded metal surface
such as the computer case (if plugged in), a metal
window frame, refrigerator, or water tap for a few
seconds.
• During installation procedures, avoid any contact
with internal parts. Handle cards only by their
edges.

Hardware Installation
WARNING: Disconnect the AC power source
before removing the cover.
2. Unplug all power cords and cables from the back of the
computer. (Be sure to note the cable connections for
reconnection when the installation is complete.)
3. Remove your computer’s cover by removing its mounting
screws with a screwdriver. Slide the cover OFF.
4. Your I/O Expander 4S card must be installed in an
available 16-bit expansion slot.
5. Remove the selected expansion slot cover by unscrewing
the holding screw and sliding the cover out. Save this
screw for securing the I/O Expander 4S card after it’s
installed.
Figure 3-1: Remove the Slot Cover
6. To install the I/O Expander 4S card, carefully align the
card’s bus connector with the selected bus slot on the
motherboard. Push the card down firmly, but gently,
until it is well seated.
3-7
I/O Expander 4S User's Manual
NOTE: Hold the card by its external edges only. Try to
avoid touching the components, connectors or pins.
7. Replace the cover slot holding screw to secure the card
to the rear slot panel.

8. Replace the computer’s cover and screws.
9. Reconnect all cables and power cord to the back of the
computer.
10. Turn your computer ON and verify that the I/O port
addresses are recognized and set properly. Most
computers will display a system configuration table,
including port addresses when it is powered ON or
rebooted.
3-8
Hardware Installation
If the ports are not recognized, please review the
installation procedures. For further help, contact SIIG's
BBS and/or technical support.
11. Turn the system power OFF and make any new serial
device connections to the I/O Expander 4S card.
You have completed the installation.
3-4 Installing the I/O Expander 4S Upgrade Kit
To add two more serial ports, you must install the I/O
Expander 4S Upgrade Kit, which can be purchased from your
dealer. This kit is comprised of:
• Two 16C550 chips
• One 1488 chip*
• Two 1489 chips*
• One bracket with one 9-pin and one 25-pin
serial connectors
*The chips, 1488 and 1489, are now built into the I/O Expander 4S.
The following steps will guide you through installing the
kit’s components.
1.
If your I/O Expander 4S board is already installed in
your system, remove it to install the upgrade chipset
and verify jumpers.
2.
Install the 16C550 into the empty socket. See figure 3-3
for a detailed layout.

the chip is matched with the notch on the socket. Make
sure all pins are aligned with the socket holes; then
gently press the chip into the socket until seated.

If this conflicts with other port assignments in your
system, reset the jumpers to non-conflicting addresses.
Refer to Chapter 3, Hardware Installation for alternative
settings.
4.
Select an available I/O slot next to the board for installing
the two-connector mounting bracket.
NOTE: If available I/O slots is a concern, you
may also remount the connectors on the bracket
into the punch-out I/O port holes provided on
the back of most computer chassis. For this option,
make sure the I/O Expander 4S board is installed
in a slot where the cables can be connected.
Remove the selected slot’s cover by unscrewing the
holding screw and sliding it out. Save this screw for
securing the connector bracket.
5. Install the I/O Expander 4S board by carefully aligning
the board’s bus connector with the selected bus slot on
3-11
I/O Expander 4S User's Manual
6. To install the connector bracket, carefully slide it into
the selected rear panel slot where the slot cover had
been removed. Replace the holding screw to secure
the connector bracket in place.
7. Connect the 10-pin connector on the end of each serial
port’s attached ribbon cable to the SIO3 and SIO4 10-pin
connectors on the I/O Expander 4S board. It does not
matter which connector on the board they are attached
to. However, make a note as to connections so you will
know each port’s COM address and IRQ.

8. Replace the computer’s cover and screws.
9. Reconnect all power cords and cables to the back of the
computer. Connect your serial peripherals to the I/O
Expander 4S ports.
You have completed the installation. Most computers
will display a system configuration table, including port
addresses when it is powered ON or rebooted. Turn your
computer ON and verify that the I/O port addresses are
set properly.
