1.0INTRODUCTION
This document describes the installation of the Eagle 100 4 port to 8 port serial I/O
upgrade. It is written for the experienced Alpha Micro Service Technician, so if you do
not feel comfortable performing the hardware procedures discussed below, please
contact your Alpha Micro Value Added Reseller or the Alpha Micro Technical Support
Group for help.
2.0DESCRIPTION
The Eagle 100 base computer can be configured for either four or eight serial I/O ports.
This upgrade kit contains the electronic components and cabling required to upgrade an
Eagle 100 4 port configuration to the full 8 port configuration.
Your AMOS Operating System Software License must be upgraded to correspond to
the additional number of serial I/O ports being added.
3.0ELECTRONIC EQUIPMENT HANDLING PRECAUTIONS
With the AC power cord unplugged and the top cover removed, the components inside
your computer are vulnerable to damage caused by static discharge. Your body and
clothing are capable of storing an electrical charge that can damage or destroy
unprotected electronic components. Prior to handling any computer hardware, make
sure your work area is properly protected against static discharge. There are a number
of commercially available static protection devices, like the wrist strap shown below,
designed specifically to protect your equipment from harmful static discharge.

4.0HARDWARE INSTALLATION
When doing a major upgrade to your computer, you want to be absolutely sure you
have a recent and complete system backup. While it is very unlikely data stored on your
hard disk drive would be corrupted when upgrading your computer—you should be
prepared for anything. Before you loosen the first screw or download any new
software, make sure all your data is copied onto some form of backup media. You
want to be absolutely sure the data on your backup media is both readable and
restorable.
To install your four port upgrade kit:
1.Remove the top cover to your Eagle computer system following the instructions in
the appropriate manual that came with your system. Make sure you follow the
safety precautions contained in your system manual.
2.Using a Phillips head screw driver, remove the cover plates on the rear panel that
cover the holes which will be used to mount the 9 pin serial I/O connectors. On
the deskside version of the Eagle 100, locations C1, C2, D1, and D2 will be
utilized for the four additional ports. On the desktop version, locations 4, 5, 6, and
7 will be utilized.
3.Remove the integrated circuit (IC) located at U29. This IC is socketed and is
located in the center of the main AM-137 logic board just to the rear of I/O
Expansion Connector J6. See the Eagle Service Manual for the AM-137 board
diagram. Make sure you use the proper IC removal tool so that the socket is not
damaged.
4.Your upgrade kit contains eight (8) integrated circuits that must be installed in the
AM-137 board as follows:
IC type
1488 Line Driver
1489 Line Receiver
DWP 137-01 PAL
68C94 I/O Controller
Socket Location
U24, U26, U27
U22, U23, U25
U29
U28*
*Note: This IC may already be installed on your board. If so, do not use the new
IC at U28.
Make sure that ICs are oriented properly before installing them into the sockets.
Pin 1 on each IC should be oriented towards the rear of the computer chassis.
5.Plug the 40-pin connector attached to one end of the I/O Expansion cable into J5
on the AM-137 board. Insure that pin 1 on the cable is oriented to match pin 1 on
J5.

6.Mount the 4 9-pin connectors at the other end of the I/O Expansion Cable into the
corresponding slots on the rear panel of your computer with the hardware
supplied in your upgrade kit.
For the deskside chassis version, arrange the connectors as follows:
Cable Connector
Rear Panel Location
Serial I/O Port
P0
P1
P2
P3
D1
D2
C1
C2
4
5
6
7
For the desktop chassis version, arrange the connectors as follows:
Cable Connector
P0
P1
P2
P3
Rear Panel Location
4
5
6
7
Serial I/O Port
4
5
6
7
7.This completes the hardware installation of your 4 port upgrade kit. Before
re-installing the computer top cover, check to make sure that all cabling is secure
and any items that you may have removed to facilitate this upgrade have been
restored to their original position. Then put the cover back on and secure with the
original mounting hardware.
5.0INITIAL TESTING
1.Before you boot the computer under AMOS, you should use the self test feature to
verify that the hardware is working correctly. For full information on the self test,
refer to the self test user’s guide shipped with the system. Perform the self test
now before actually booting up the system.
2.After the self test has been successfully run, you should be ready to boot your
computer under AMOS. Your system should boot just as it did before you
installed this I/O expansion kit. You will need to update your AMOS32.INI to
enable the four additional serial ports.

6.0SYSTEM INITIALIZATION COMMAND FILE (EAGLE 100)
Now that you have added the hardware to support a total of eight serial I/O ports, you
will need to define these ports in your system initialization command file. This file, which
is located in the SYS: account, is called AMOS32.INI. Within this file, serial ports are
defined using an octal (base 8) numbering system. The following table shows the
corresponding octal port numbers for the AM-137’s eight on board serial ports:
AM-137 BOARD’S EIGHT ON-BOARD I/O PORTS
OCTAL PORT NUMBERING
FOUR SERIAL PORTS CONNECTED TO J4
FOUR SERIAL PORTS CONNECTED TO J5
0-3
4-7
To illustrate how serial ports are defined in the AMOS32.INI file, we’ll construct a
sample system initialization command file based on a Eagle 100 configuration that
includes the eight on-board serial ports. A rear panel illustration based on this example
is shown below:
MAIN

FOUR ON-BOARD SERIAL

Eagle 100 Deskside Rear Panel Configuration
In the example above, the serial port connectors have been positioned on the rear panel
based on instructions in a previous section. The octal port number assigned to each port
came directly out of the table at the beginning of this section.

Installation Instructions: AM-137 Four-Port I/O Expansion Kit
Page 5
Now that we know the corresponding octal number for each of the serial ports in our
example, we can define them in the system initialization command file. It’s never a good
idea to directly modify your AMOS32.INI file; always create a test file; type:
LOG SYS: RETURN
COPY TEST.INI=AMOS32.INI RETURN
Several areas in the TEST.INI file need to be modified:
1.You need to make sure the total number of jobs assigned to the JOBS statement is
increased by the number of new serial ports being added to the computer.
2.You must also add some additional JOBALC statements. JOBALC allocates a name to
each defined job.
3.Your Eagle 100 computer requires a healthy quantity of queue blocks. When you add
new serial ports, you have to increase your queue block allocation. Use the following
queue block formula to determine how many queue blocks you require.
NEW QUEUE BLOCKS REQUIRED = OLD QUEUE BLOCKS + (13 x NUMBER OF JOBS BEING ADDED)
4.You will also need to add a TRMDEF statement to your system initialization command file
for each new port. The TRMDEF statement is where the octal port number is assigned.
The basic elements that make up a TRMDEF statement are shown below:
TRMDEF command
Assigned name
Serial port driver name
Octal port number
TRMDEF
TERM7,AM318=6:19200,ALPHA,100,100,100
BAUD rate
Terminal driver name
In-width buffer size
In-buffer size
Out-buffer size
NOTE:
Make sure you use AM318 as the serial port driver name for the Eagle 100.
MC1221
TRMDEF Command Statement
5.Finally, you will add SETJOB statements that attach the JOBALC name to the TRMDEF
name, assign memory to the job, and log the job on.

6.1Finishing the Installation
Once you have created a TEST.INI file that is applicable to your configuration, you need
to verify it has been correctly modified. You do this by using the MONTST command:
LOG OPR: RETURN
MONTST AMOS32,TEST.INI RETURN
Watch closely as the system initialization command file is executed; make sure no
errors are displayed on your terminal screen. If an error does occur, take another look at
your TEST.INI file; double check your octal port numbers and other statements you
added to support the serial ports.
After you are certain your TEST.INI file is working correctly, execute the following
command:
COPY AMOS32.INI = TEST.INI RETURN
