Introduction

1.1 About the Serial Communication Modules

The serial communication modules are intelligent serial input/output

multi-port controller cards, which go with the new generation of PC
platform CompactPCI. The modules can reduce the frequency for serial
communication controller to interrupt main CPU on the mainboard to
improve the whole system performance.

Traditionally, the serial communication controller will interrupt the MPU

character by character. This action will waste MPU processing time and
drop the system computing power. If the MPU is processing some
non-interrupted task, then the serial controller will overrun and data lost.

The serial communication interface series can support buffer capability or

local processor and dual port RAM in each port’s transmit and receive
channel simultaneously. This capability will reduce the frequency of
interrupt and increase the non-interrupt task’s interval.

The serial communication interface series use ASIC PCI controller to

interface the module to cPCI bus. The ASIC fully implement the PCI local
bus specification Rev. 2.1. All related bus configurations, such as base
memory address and interrupt assignment, are automatically controlled
by BIOS software. It does not need any user interaction and pre-study for
the configurations. This removes the burden of searching for a
conflict-free configuration.

Installation

This chapter describes the configurations of the serial communication module. At
first, the contents in the package and unpacking information that you should care
about are described. The serial communication modules are plug-and-play and
very easy to install into cPCI system.

2.1 What You Have

In addition to this User's Manual, the package includes the following
items:

• cPCI-3534/3538 Serial Communication Interface Module

• Expansion Cable

• R-3534/3538 Rear IO Daughter Board (For the rear I/O version)

• “ADLink All-in-One Compact Disc” or Disks

If any of these items is missing or damaged, contact the dealer from whom
you purchased the product. Save the shipping materials and carton in case
you want to ship or store the product in the future.

Installation • 11

2.2 Unpacking

Your serial communication module contains sensitive electronic
components that can be easily damaged by static electricity.

The module should be done on a grounded anti -static mat. The operator
should be wearing an anti-static wristband, grounded at the same point as
the anti-static mat.

Inspect the module carton for obvious damage. Shipping and handling
may cause damage to your module. Be sure there are no shipping and
handing damages on the module before processing.

After opening the module carton, extract the system module and place it
only on a grounded anti-static surface component side up.

Again inspect the module for damage. Press down on all the socket IC's to
make sure that they are properly seated. Do this only with the module
place on a firm flat surface.

Note: DO NOT APPLY POWER TO THE MODULE IF IT HAS BEEN

DAMAGED.

You are now ready to install your cPCI Module.

2.3 Installation Procedure

1. Turn off your computer

2. Turn off all accessories (printer, modem, monitor, etc.) connected to
computer.

3. Select a cPCI slot.

4. Before handling the serial communication module, discharge
any static buildup on your body by touching the metal case of
the computer. Hold the edge and do not touch the
components.

5. Position the module into the cPCI slot you selected.

6. Secure the module in place of the system.

12 • Installation

2.4 Hardware Configuration

The serial communication module has plug and play component, the card
can requests memory usage (I/O port locations) of the card which is
assigned by system BIOS. The address assignment is done on a
board-by-board basis for all serial communication cards in the system.
The jumper SW1 -1 for cPCI-3534 and the JP1 for cPCI-3538 is used for
the system to recognize the first or second card of the same model in the
system if there are two cards of the same on board.

2.5 Software Installation

2.5.1 Windows NT Installation

Once Windows NT system has been started, login using an account with
administrative right.

1. Start the [Control Panel] applet by double clicking the icon in the
[Program Managers] main group

2. In the [Control Panel] applet, double click [Network] icon to bring up
the Network Control Panel Applet (NCPA).

3. Within the NCPA, select the [Add Adaptor] button, a list of possible
adaptors should be displayed. Go to the end of this list and select
<Other> requires disk from manufacturer.

4. When prompted for the path, specify the drive and directory where
the NCPA can find the new driver for the card you install.

For cPCI -3534, we may specify as follow:
X:\NuCOM\CPCI3534\NT4

For C588, we may specify as follow:
X:\NuCOM\CPCI3538\NT4
( Where X indicates CD-ROM drive )

5. Now, you can follow the configuration dialog boxes to install the
driver.

6. In the default condition, the TTY port is given name from “COM3”.
User can specify the start “COM” port number in installation
procedure.

Installation • 13

7. We can install up to two same type serial communication cards in one
NT system.

8. When you need to install two same type serial communication cards

in one NT system, you must confirm to let one card’s SW1 -1 is ON
while the other card’s SW1 -1 is OFF for cPCI-3534 and JP1 is ON
while the other card’s JP1 is OFF for cPCI -3538.

9. The card with switch ON will have low COM port number. The card

with switch OFF will have higher COM port number follow the card
with switch ON.

10. If you install two the same type serial communication modules with

switch ON or OFF simultaneously, we can not confirm that both cards
will active properly.

11. If you install multiple cards in one NT system simultaneously, please

confirm that the COM port number assigned do not overlap for
different card. Or you may have improperly operation in your system.

12. For easy to maintain NT system’s COM port number, we suggest that

you must set the switch ON for the first card to be installed in NT
system.

13. After you install the driver, you need to reboot your PC, then you can

have more COM port available.

14. If you had installed our NT driver in your system before, you might

remove this driver firstly, then you can install our new version driver.
Or you might have some problem in your system.

2.5.2 Windows 95/98 Installation

Once Windows 95/98 system has been started, the plug & play function in
95/98 system will find the new serial communication card. If this is the first
time to install serial communication card in your Windows 95/98 system,
you will be informed to install the driver. Please follow the instruction
message to input the COM port number starting value for the first and
second cards.
Because the resource will be assigned by PCI BIOS, it is not easy to check
which card is first or second from resource. So the switch will play the role
for system to fix the COM port number for each card.
After you had installed the driver, you might be informed to have new
hardware found. You do not have to install the driver again, Windows
95/98 will add the COM port automatically.

14 • Installation

1. You can install up to two cPCI -3534/3538 cards in one 95/98 system.

2. When you need to install two same type cards in one 95/98 system,
you must confirm to let one card’s switch is ON, and the other card’s
switch is OFF.

3. The card with switch ON will have COM port number assigned for first
card. The card with switch OFF will have COM port number assigned
for second card.

4. If you install two the same type serial communication cards with
switch ON or OFF simultaneously, we can not confirm that both cards
will active properly.

5. If you install multiple cards in one 95/98 system simultaneously,
please confirm that the COM port number assigned does not overlap
for different card. Or you may have improperly operation in your
system.

6. For easy to maintain 95/98 system’s COM port number, we suggest
that you must set the switch ON for the first card to be installed in
95/98 system.

7. The serial communication card can be used in interrupt shared mode.
PCI BIOS will assign IRQ for each serial communication card. For
multi-card application, we can just share one IRQ in each card, but
you must confirm that one system may have minimum one IRQ left for
P&P function. If there are no IRQ left to be assigned to serial
communication card, you might have wrong operation.
