Page 1INSTALLATION INSTRUCTIONS: AM-314 Four Port I/O Board
1.0INTRODUCTION
The instructions in this document describe the installation of AM-314 four-port serial I/O
boards into AM-1600 (both desktop and deskside models), as well as Eagle 100, 200,
and 300 computers. The information is written for the experienced Alpha Micro Service
Technician, so if you do not feel comfortable performing the hardware and software
procedures discussed below, please contact your Alpha Micro Dealer or the Alpha Micro
Technical Support Group for help.
2.0PRODUCT DESCRIPTION
The AM-314 board supports four asynchronous serial I/O ports. AM-314 serial ports can
be individually configured for either RS232 or RS422 protocols. Each AM-314 board is
linked to the rear panel of your computer using a 40-pin cable with four female DB9
connectors at one end and a standard 40-pin connector at the other. The AM-1600’s
AM-135 board has four slots designed for serial I/O expansion. Eagle 300 computers
have also have four I/O expansion slots; Eagle 200 computers have two I/O expansion
slots; and Eagle 100 computers have one I/O expansion slot.
Eagle computers also support the AM-318 eight-port serial I/O board. Special
instructions on mixing AM-314 and AM-318 boards in Eagle computers can be found in
the
AM-318 Eight-Port Serial I/O Board Installation Instructions.
3.0CONFIGURING YOUR AM-314 BOARDS
There are no address jumpers on the AM-314 board. In fact, the only jumpers on the
board are the RS422/232 jumpers. The jumpers at location W0 control the RS422/232
selection for the first port; the W1 jumpers control the second port; the W2 jumpers
control the third port; the W3 jumpers control the fourth port. All boards are shipped
configured for RS232 as shown in the illustration below:

Page 2 INSTALLATION INSTRUCTIONS: AM-314 Four Port I/O Board
4.0INSTALLATION OVERVIEW
The installation instructions are identical for AM-1600 desktop and deskside computers;
however, there are some significant differences in the procedure for installing an
AM-314 board into an Eagle computer. Because of the differences, the AM-1600
(desktop and deskside) AM-314 installation instructions and the Eagle AM-314
installation instructions will be split into two sections. Section 5.X will include the
AM-314 installation information for AM-1600 computers and Section 6.X will include the
AM-314 installation information for Eagle computers.
5.0AM-314 INSTALLATION (ALL AM-1600 COMPUTERS)
The first step in the installation process is to remove the computer’s top cover.
Instructions for removing the top cover from the AM-1600 desktop model are located in
the
AM-1600 Computer Owner’s Manual . For the deskside AM-1600, instructions for
removing your computer’s top cover are located in the
AM-1600 Deskside Computer
Service Manual.
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 designed specifically to protect your
equipment from harmful static discharge.
Once the top cover is removed, you will be able to access your computer’s main circuit
board, which is called the AM-135. The AM-135 board has four expansion slots
designed for AM-314 I/O boards.
The AM-135 board illustration, located on the following page, shows the four serial I/O
expansion slots: J17, J16, J15, and J14. As indicated in the illustration, the first I/O
board installs in J17, the second in J16, the third in J15, and the fourth in J14.

Page 4 INSTALLATION INSTRUCTIONS: AM-314 Four Port I/O Board
The AM-135’s I/O expansion slots are very similiar to the type of slots memory SIMM
modules plug into. The AM-314 board should be inserted into the appropriate slot with
the component side of the AM-314 board facing your computer’s rear panel. The
AM-314 must be inserted into the expansion slot at a slight angle and after you feel the
board settle into the slot, you rotate it into an upright position. When the AM-314 is
properly positioned, the metal retainer clips at each end of the expansion slot will click
into position, locking the board in place.
5.1Installing the I/O Cables
The cable that links your AM-314 board to the rear panel of your computer has four
female DB9 connectors at one end and a standard 40-pin connector at the other. Plug
one 40-pin I/O cable into each of the AM-314 boards. The 40-pin connector on the
AM-314 board has an embossed arrow showing the pin-1 location. Make sure the red
stripe on the I/O cable aligns with the embossed arrow on the connector.
The rear panel of your computer has 16 DB9 cutouts labeled 0 through 15. The
illustration on the following page shows the DB9 connector orientation for both desktop
and deskside AM-1600 computers:

locations 4, 5, 6, and 7. The AM-314 board plugged into connector J15 attaches to the
rear panel at locations 8, 9, 10, and 11. The AM-314 board plugged into connector J14
attaches to the rear panel at locations 12, 13, 14, and 15.
PDI-00314-00, Rev. A04

Page 6 INSTALLATION INSTRUCTIONS: AM-314 Four Port I/O Board
One end of the AM-314 40-pin I/O cable splits of into four separate cables, each with its
own DB9 connector. Notice how the cable leading to each of the DB9 connectors is
marked:
(P0, 4, 8, 12)
(P1, 5, 9, 13)
(P2, 6, 10, 14)
(P3, 7, 11, 15)
The first number following the letter "P" applies to the AM-314 board installed in
connector J17; the second number following the P applies to the AM-314 board installed
in connector J16; the third number following the P applies to the AM-314 board installed
in connector J15; the last number following the P applies to the AM-314 board installed
in connector J14.
Attach the DB9 connectors to the rear panel of your computer, using the 3/16" hex-nuts
included in the mounting kit.
Re-install the AM-1600M top cover.
5.2Modifying the System Initialization Command File
In order to use a serial port, it needs to be defined in your system initialization command
file. This file, which is located in the SYS: account, is called AMOSL.INI. Within this file,
serial ports are defined using an octal (base 8) numbering system. The octal number
used corresponds directly to what slot on the AM-135 a particular I/O board is plugged
into. The following table shows the AM-314 octal port numbers for each of the four I/O
expansion slots on the AM-135 board:

PDI-00314-00, Rev. A04

Page 7INSTALLATION INSTRUCTIONS: AM-314 Four Port I/O Board
To illustrate how AM-314 serial ports are defined in the AMOSL.INI file, we’ll construct a
sample system initialization command file based on the installation of four AM-314
boards.
It’s never a good idea to directly modify your AMOSL.INI file; always create a test file;
type:
LOG SYS:
RETURN
COPY TEST.INI=AMOSL.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. The
example configuration has four AM-314 boards, which is a total of 16 serial ports.
For our example configuration, we will set the JOBS statement to 22, which will
allow for all the serial ports, the AM-1600’s one on-board parallel port, and a
couple of extras to support spawned jobs.
2.You must also add some additional JOBALC statements. JOBALC allocates a
name to each defined job. In our TEST.INI file, we’ll use names like JOB1, JOB2,
etc. However, you could just as easily use TOM, DICK, HARRY, etc.
3.Roadrunner enhanced AM-1600 computers require a healthy quantity of queue
blocks. When you add new serial ports, you need to increase your queue block
allocation. Use the following queue block formula to determine how many queue
blocks you require.
NEW QUEUE BLOCK REQUIREMENT = OLD QUEUE BLOCKS + (13 x THE NUMBER OF JOBS)
For example, if the QUEUE statement in your system initialization command file is
currently set to 200 and the JOBS statement is set to 22, the resulting formula
would look like this:
NEW QUEUE BLOCK REQUIREMENT = 200 + (13 x 22)
For our example, the QUEUE statement should be changed to 486 to
accommodate our new queue block requirements.
4.You will also need to add a TRMDEF statement to your TEST.INI 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:
