CHAPTER 1
INTRODUCTION
The PCCOM PCI bus 8 port universal RS232 adapter is an 32 bits
PCI bus board with Plug and Play (PnP) features, it provides eight
asynchronous RS232 serial communication ports, which link the
computer and serial peripheral devices such as terminals, modems,
serial printers, plotters, ... etc.
The PCCOM PCI bus 8 port universal RS232 adapter is particularly
suited to facilitate the connection of terminals (VDUs) in multi-user
operating systems. The PCCOM board may be installed in any
Pentium or hardware compatible systems. The PnP features let
hardware configuration for IRQ and I/O address is detected by
BIOS automatically, you don’t need set switch and jumper.
Since most of the computer has its own COM1 and COM2, the
PCCOM PCI bus 8 port universal RS232 adapter can be configured
from COM3.
On board XR16C854 chip provides four 16850 functions which
contains 128 bytes FIFO buffer for each 16850 ports. There are two
kinds of board can be choose, one is dual speed (clock rate is
7.3728MHZ) board that its baud rate up to 230K, another is octal
speed board (clock rate is 14.7456 MHZ) that its baud rate up to
1M.
The features of the PCCOM PCI bus 4 port universal RS232
adapter are:
•32 bit PCI bus with Plug and Play (PnP) features.
•Eight RS232 ports for asynchronous communications.

•Suitable for SCO UNIX, Linux, MS/DOS, WINDOWS
NT/2000/XP, WINDOWS 95/98/ME, OS/2... etc.
•Pentium hardware compatibles.
•On board XR16C854 chip.
•Provides eight 16850 ports that contains 128 bytes FIFO for
each port.
•External or internal clock rate selectable.
•Dual speed (clock rate is 7.3728MHZ) board that its baud
rate up to 230K. Octal speed board (clock rate is 14.7456
MHZ) that its baud rate up to 1M.
•Provides RS232 interface for 3.3V internal voltage, which
has lower power consume.
•Up to 4 boards be installed in one computer system.
•Software compatible with PCCOM98/2000.
•Operating temperature 0 to 60 ºC.
•Storage temperature -20 to 70 degree °C.
•Humidity 5% to 95% in non-condensing.

Before installing your PCCOM PCI bus 8 port universal
RS232 adapter, make sure that:
•The host computer is a Pentium or its compatibles.
•The switch and the jumpers are properly configured.
•The operating system you intend to use is capable of driving
multiple serial ports.

Your PCCOM PCI bus 8 port universal RS232 adapter is designed
to be inserted in any available PCI slot in your Pentium or
compatibles. You must plug this board to your computer before
installing PCCOM software. In order to gain access to the expansion
slots, follow the steps listed below:
1. Turn off all power to your computer and all peripheral
devices before installing your PCCOM PCI bus 8 port
universal RS232 adapter.
2. Remove the cover of the computer.
3. Set the SW1 to identify card number.
4. Set the JP2 to select clock source.
5. Insert the PCCOM PCI bus 8 port universal RS232 adapter
into any available PCI slot. Make sure the adapter is firmly
seated in the chosen slot.
6. Replace the cover of the computer.
7. Connect cables to DB9 connectors as required.
8. Turn on the power of your computer.

The Plug and Play features let hardware configuration for IRQ and
I/O address is detected by BIOS automatically, so that it need not
switch and jumper setting. The on board switch can be used to
identify card number by the users (if you do not set the switch, the
PnP BIOS will assign card number automatically).
JP2 (Jumper 2)
Select external clock or internal clock.
SW1 (Switch 1)
Identifies card number.
Do not set up jumpers and switch under power on condition,
otherwise it may defective your computer system.

2. Card Identifier
The switch is used to identify card number, default setting is card 15,
and there are two methods to set the card number:
a. PnP mode
Just plug in PCCOM PCI bus 8 port adapter into PCI slot, the PCI
BIOS will allocate I/O address to each adapter automatically and
assign card number start from 0 to each adapter. You may set any
card number at PnP mode, and you need use software tools to
distinguish port id. Almost all of the operating systems run at PnP
mode.
b. manual mode
Set card number by card identifier switch, the PCI BIOS will
assign pre-allocated I/O address to each adapter. Please set
different card number to each adapter (do not duplicate card
number setting).
