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:
