Introduction
BUF-PCI(PC), BUF-PCI(98) 1
1. Introduction
About the BUF-PCI(PC) or BUF-PCI(98)
Thank you for purchasing the BUF-PCI(PC) or BUF-PCI(98).
The product is a bus conversion adapter that allows you to add ISA or C
bus-equivalent expansion slots by connecting the PCI bus expansion
slot in the PC with the CONTEC I/O expansion unit.
Please read this document thoroughly before starting building a system,
including creating application programs and connecting with external
devices.
This product consists of the following
-BUS-PCI(PCI) board (to be mounted in the PCI bus expansion slot in
the PC)
-BUS-PCI(PC) board or BUS-PCI(98) board (to be mounted in
CONTEC's I/O expansion unit)
-Cable for connecting the above two products
In order to use the adapter, you need an I/O expansion unit FA-PAC
series, which is sold separately, in addition to the above.

Introduction
BUF-PCI(PC), BUF-PCI(98)2
Features
-The BUS-PCI(PCI) board is a PCI bus-compliant interface board
which can be used with the IBM PC-AT compatibles, NEC
PC98-NX series, and PC-9800 series in which a PCI bus expansion
slot is available.
-Allows you to add I/O-accessible ISA or C bus-equivalent expansion
slots.
-Verifies an interrupt request from the interface board mounted in the
I/O expansion unit to accomplish the interrupt process.
-Driver software for control of the interface board mounted in the I/O
expansion unit is available for Windows XP, Windows 2000,
Windows NT, Windows Me, Windows 98 and Windows 95.
-The I/O access wait and the refresh signal for the I/O expansion unit
can be enabled or disabled.
-Comes with a self-diagnostic feature.
Functions
General-purpose I/O accessing
Allows you to access an added expansion slot for I/O. The I/O wait can
be specified with software.
Interruption
An interrupt can be generated with an interrupt request signal from the
added expansion slot. The status of the interrupt request signal can also
be verified.
Control of the refresh signal
Enabling or disabling of the refresh signal for the added expansion slot
can be specified with software.
Self-testing
Allows self-testing using a dedicated register mounted on the board.

Introduction
BUF-PCI(PC), BUF-PCI(98)4
Restrictions
The expansion slot this product adds to the I/O expansion unit is not
fully compatible with the expansion slot in the PC. For this reason, a
board that can be mounted and used in the expansion unit is subject to
some restrictions.
A board that operates only with I/O accessing (I/O instructions) can be
mounted and used in the expansion unit. A board that requires
specialized operations might not function properly even if it operates
with I/O accessing. Before using therefore, be sure to verify the
specifications of the board you will be mounting in the I/O expansion
unit.
The following boards cannot be used.
-A board that uses specific I/O port addresses (a board that does not
allow its I/O port addresses to be reset, such as a PnP board)
-A board that uses memory accessing (a memory expansion board or a
board that uses an extended ROM area)
-A board that uses DMA
-A board that outputs control signals to the PC, such as an external
CPU board
-A board that is used to add another I/O expansion unit
-A board specifically mentioned that it cannot be used in the manual
of a PC which uses an I/O expansion unit
-A board that requires an I/O wait of more than one microsecond
-A board that uses I/O port address lower 8 bits F8h-FFh

Handling Precautions
Be aware of the following precautions when handling this board:
-To prevent the board from being damaged, avoid shock and vibration
and do not bend the board.
-Do not modify the board. CONTEC is not responsible for modified
boards.
-Do not touch gold-plated terminals (edge connectors) on the board.
Touching the terminals causes poor contact. If you accidentally
touch a terminal, wipe it off with industrial alcohol.
-The board has switches which you need to set. Be sure to verify these
switches before mounting the board in the slot.
-Set the switches and jumpers on the board as designated. Setting
them otherwise will cause failures.
-Connect only designated signals to the connectors on the board.
Connecting otherwise will cause failures.
-Mount the board only in the designated expansion slot.
-Do not insert or remove the board with the PC or the I/O expansion
unit turned on. Inserting or removing the board with either power
turned on will cause failures. Be sure to turn the PC or the I/O
expansion unit off.
-The total current consumption of the board to be mounted in the
expansion slot of the PC or I/O expansion unit must not exceed the
power capacity allowed for the PC or the I/O expansion unit.
Exceeding the limit will cause failures.

Setup Procedure
Set up the product following these steps.
(1) Setting up and mounting the BUS-PCI(PCI) board
(2) Setting up and mounting the BUS-PCI(PC) or BUS-PCI(98) board
(3) Connecting the PC to the I/O expansion unit

Setting Up and Mounting
the BUS-PCI(PCI) Board
DIP switch SW1 allows you to set whether or not to use interrupt
resources and the board ID. Figure 2.1 shows its factory settings.
Figure 2.1. DIP Switch SW1
Setting Whether or not to Use Interrupt Resources
Specify whether or not to use interrupt resources with DIP switch
SW1-1.
When using the interrupt function of the board mounted in the I/O
expansion unit, set SW1-1 to ON. This allows an interrupt request to be
sent to the PC through the PCI bus using one interrupt resource
assigned to the BUS-PCI(PCI) board.
If SW1-1 is set to OFF, no interrupt resource is assigned from the PC to
the BUS-PCI(PCI) board.

OFF Disabled
ON Enabled

Setting the Board ID
A board ID is the number by which a BUS-PCI(PCI) board is identified.
When several of these boards are used with one PC, board IDs allow
each BUS-PCI(PCI) board to be distinguished.
Specify a different value for each board ID.
To specify a board ID, use SW1-5, 6, 7, and 8. Board IDs can be set in
a range of 0-15 for a maximum of 16 boards.
When using just one board, use its factory setting (board ID=0).

- Set SW1-3 and SW1-4 to OFF.
Mounting the BUS-PCI(PCI) Board
After making sure that the PC is turned off, disconnect the PC power
plug from the socket on the equipment.
Next, mount the BUS-PCI(PCI) board in the PCI expansion slot in the
PC. For information about mounting the board, see mounting
instructions in the PC manual.
Note! Before mounting the BUS-PCI(PCI) board, be sure to disconnect the
PC power plug from the socket on the equipment.

Setting Up I/O Expansion Unit Power Control
CN2 is the connector to be connected to a power supply source in
compliance with ATX specifications.
When using with an I/O expansion unit having an ATX power supply
source, connecting each terminal to 5VSB, PS-ON, and GND of the
ATX power supply source allows you to interlock the I/O expansion
unit power with the turning ON/OFF of the PC.
CN3 on the BUS-PCI(PC) board is the connector that connects to the
power LED on the I/O expansion unit.

After making sure that I/O expansion unit is turned off, disconnect its
power plug from the socket on the equipment.
Next, mount the BUS-PCI(PC) or BUS-PC(98) board in the I/O
expansion unit. For information about mounting either board, follow
instructions in the manual that came with the expansion unit.
Note! Before mounting the BUS-PCI(PC) or BUS-PC(98) board, be sure to
disconnect the I/O expansion unit power plug from the socket on the
equipment.
