Introduction
1.1 About the Serial Communication Modules
The serial communication modules are intelligent serial input/output
multi-port controller cards, which are with the new generation of PC
platform CompactPCI. The modules can reduce the interval 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 number of interrupt
and increase the non-interrupt task’s interval.
The serial communication interface series used ASIC PCI controller to
interface the module to Compact PCI bus. The ASIC fully implement the
PCI local bus specification Rev. 2.1. All bus relative configurations, such as
base memory address and interrupt assignment, are automatically
controlled by BIOS software. It does not need any user interaction and
pre-studyfortheconfigurations.Thisremovestheburdenofsearchingfora

Installation
This chapter describes the configurations of the serial communication modules.
At first, the contents in the package and unpacking information that you should
care about are described. The serial communication cards are plug-and-play and
very easy to install into any cPCI system.
2.1 What You Have
In addition to this User's Manual, the package includes the following
items:
•cPCI-3938 Serial Communication Controller Module
•Software Utility CD or Disks
•cPCI-6968/cPCI-6969 Expansion Module
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.
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.

•
Installation
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 CARD 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 expansion 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 board into the cPCI slot you selected.
6. Secure the card in place ofthe system.

2.4 Hardware Configuration
Theserialcommunicationmodulehasplugandplaycomponent,thecard
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 JP1 for the serial communication card 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.
We may specify as follow:
A: \Nt4
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.
7. We can install up to two same type serial communication cards in
one NT system.

8
•
Installation
8. When you need to install two same type serial communication cards
in one NT system, you must confirm to let one card’s jumper JP1 is
ON while the other card’s jumper JP1 is OFF.
9. The card with jumper ON will have low COM port number. The card
with jumper OFF will have higher COM port number follow the card
with jumper ON.
10.If you install two same type serial communication cards with jumper
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
differentcard.Oryoumayhaveimproperlyoperationinyoursystem.
12.For easy to maintain NT system’s COM port number, we suggest
that you must set the jumper 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 UNIX/XENIX Installation
Under the UNIX/XENIX operation system, the serial communication card
is an extra peripheral device. A device driver should be linked with the
kernel to build a new kernel system. The serial communication system
will work after the new kernel system is restarted.
The installation environment could be
1. IBM PC/AT X86 or other compatible machine.
2. UNIX system V release 3 releases 4 or SCO XENIX system V.
3. Under the above environment, all the link kit packages should be
installed completely.
Files in the installation diskette have
1. /etc/PCIIOP/README
2. /etc/PCIIOP/build
3. /etc/PCIIOP/d1
4. /etc/PCIIOP/OBJ/P960F.O (For different card, replace P960F to

“unit =” denotes the installation card number in the system.
“type =” denotes the PCIIOP interface card type.
“map =” denotes the mapping address and memory space of dual port

When the above message appears and the active LED in
cPCI-6968/cPCI-6969 expansion module light on, it means the
communication interface controller has been installed successfully.
Ifthemessageof“map=”or“ports=”isnotcorrect(includingnomessage)or
any of the LED in cPCI-6968/cPCI-6969 module is not on, you should
proceed error detecting and correcting procedure as follows:
1. Shutdown the operating system, turn off the power.
2. If you can not boot the system successfully, please check the voltage
level. If the voltage level is too low to boot the system, check the
number of controller module and cPCI-6968/cPCI-6969 module.
3. Insure the controller interface module has been inserted correctly at
system expansion slot. Insure the rear connector has been
connected correctly between controller module and
cPCI-6968/cPCI-6969 module.
4. Checkthememorymappingsettingandinsurethatitdoesnotconflict
with other device’s memory mapping.
5. Turn on the power and reboot the operating system. If you can insure
the device driver is well installed, it is not necessary to re-execute the
software installation procedure. Otherwise you may need to
re-execute the software installation procedure.
6. If the message does not indicate correctly, please repeat previous
procedure or contact your supplier.
