PCI-2000 TECHNICAL MANUAL
INTRODUCTION
This manual describes the installation and operation of the HAL
PCI-2000 Personal Computer Interface. This interface is
specifically designed to allow use of the PC, PC-XT, PC-AT, and
PC-Portable models of the IBM Personal Computer in radio systems.
The PCI-2000 may also be used with some models of other
manufacturers that are "PC-compatible". Since it is impossible
to include data on all the possible variations of "compatible"
computers, the performance of the PCI-2000 is only warranted for
installation in IBM Corp. personal computers (see LIMITED
WARRANTY at end of manual).
The PCI-2000 includes a large number of features, giving a great
deal of flexibility to the operator. It is suggested that the
operator particularly read all of Chapters 1 and 2 before
installing the circuit board and Chapter 3 before attempting use
of the software.

When
unpacking your PCI-2000, carefully inspect the shipping
carton, the circuit board, and the software diskette for shipping
damage. Any evidence of damage should be immediately reported to
your supplying dealer or shipping carrier. Be sure to save all
packing materials if damage is found - the shipping carrier will
want to inspect them for any insurance claim. Check the
accessories against the following list. If any are found
missing, double-check the packing for loose parts and notify your
dealer or HAL Communications Corp. so that the shortage may be
rectified. Please be sure to specify the HAL part number!

CHAPTER 1 INSTALLATION
Page 4
*****************************************************************
NOTE: The PCI-2000 has been tested in "standard" versions and
models of the IBM-PC and works well with the IBM video card, disk
controller card, and serial communications cards installed.
However, HAL Communications cannot assume responsibility for
operation (or non-operation) of the card when other options are
installed in the computer. If problems are experienced, try
removing extra option cards until correct operation is observed.
*****************************************************************
1. 2. 2 IBM PC
The PCI-2000 may be installed in any of the slots available in
the IBM-PC. It is recommended, however, that it be inserted in
the first slot on the left (connector J1) if at all possible.
Choose the desired slot, install the supplied plastic card guide,
and plug-in the PCI-2000.
1.2.3 IBM PC-XT
The
PCI-2000 may be inserted into any of the long-card slots in
the PC-XT with the left-most slot being preferred. Choose the
desired slot, install the supplied plastic card guide, and plug-
in the PCI-2000.
1.2.4 IBM PC-AT
The
PCI-2000 may be used in any long-card slot of the PC-AT, but
you may prefer to use a slot that has only the rear card
connector to save the two-connector slots for other devices.
Choose the desired slot and plug-in the PCI-2000.
1.2.5 IBM PC-Portable
When installed in the PC-Portable model, it is recommended that
you first move the video card from the slot next to the monitor
to the second slot (connector J2). Then, install the PCI-2000 in
the left-hand slot (connector J1). This is necessary to avoid
mechanical conflict with the CRT controls and keyboard connector
on the front panel.
1.2.6 IBM "Compatibles"
Due to the rapid growth of the "PC-Compatible" market, it is
impossible to list all possible models and variations.
Compatibility questions should be addressed to HAL sales
personnel. In general, the PCI-2000 will ONLY work if the
hardware and firmware conditions listed in Table 2 are met
by the "compatible" personal computer:

CHAPTER 1 INSTALLATION
TABLE 2.
REQUIREMENTS FOR "PC-COMPATIBLE" COMPUTERS
1. Compatible ROM BIOS routines.
2. Compatible Bus connector
3. Compatible Interrupt Routines
4. Have COM1 or COM2 serial I/0 channel
unused or provision to disable any
on-board serial device using these
addresses.
Page 5
Because of the great variation in the use of the word
"compatible", HAL cannot assure proper PCI-2000 operation in any
but the above mentioned IBM Corporation models of the Personal
Computer.
1.3 Software Installation
The software for the PCI-2000 is supplied on one 5.25" floppy
diskette. You should make back-up copies of this diskette BEFORE
attempting operation. It is recommended that you place a write-
protect tab on the HAL diskette. This will help prevent
accidental erasing of the original diskette when copying the
files. The DOS system files must also be included on the
operating PCI-2000 diskette, so first prepare new diskettes using
the FORMAT/S command. Next, copy the PCI-2000 files onto the
newly formatted diskettes. Refer to your DOS manual for proper
procedures for your computer configuration. After copies have
been made, store the original HAL diskette in a safe location and
use a copied diskette for normal operation.
*****************************************************************
NOTE: The PCI-2000 software will function only with the HAL
PCI-2000 circuit board. The PCI-2000 software is copyrighted by
HAL Communications Corp. and duplication of the software for
other than your own use with the PCI-2000 is specifically
prohibited. Any attempt to copy this software for resale or any
use other than with the supplied PCI-2000 circuit board will be
vigorously prosecuted to the full extent of the copyright laws.
*****************************************************************
After the PCI-2000 circuit board is installed in your computer
(but before connection to the radio system), refer to section
3.1.1 of this manual, install the PCI-2000 diskette in disk drive
1, and boot the computer ("cold" or "warm" boot). The diskette
includes an "AUTOEXEC.BAT" file that will first request the time
and date and then automatically load the PCI-2000 software. You
will first see the title page with copyright notice, and software
version number. Remember the version number! We will need to
know this version number if you call HAL with a problem.

CHAPTER 1 INSTALLATION
Page 6
Some brands of clock cards may be used with the PCI-2000 and the
necessary calling routine should then be inserted in the
AUTOEXEC.BAT file. The clock card software routine must also be
copied onto the PCI-2000 software diskette. Further details
about clock cards are found in section 3.5.4 of this manual.
Approximately 6 seconds after the title page appears, you will
see the operating screen format of the PCI-2000 with a status
line on top and a vertical row of line numbers down the left
margin. The top half of the line numbers are for the receive
buffer (12-1 using bright video). The transmit buffer line
numbers show in the lower half of the screen (1-12 using dim
video). Typed characters should show in dim video on the lower
half of the screen. Control of the PCI-2000 board and screen
features will be discussed in detail in Chapter 3.

CHAPTER 2
CONNECTIONS
Page 7
All I/0 connections to the PCI-2000 are made via the 25-pin
connector on the rear panel. All signals required for direct
connection to a radio system, an RTTY tuning indicator, the
internal 103/202 modem, or an external modem or computer are
supplied on this connector. Therefore, the cable connections
will vary with the intended application and few installations
will require use of all 25 pins. Note that this DB25 connector
is NOT compatible with "standard" DB25 modem connectors! All
PCI-2000 I/O connections are explained in Table 3 and voltage and
current limitations in Table 4.

2.1 Radio Connections
If a single-cable harness is to be used with the radio system,
all wires may be connected to the supplied DB-25 connector.
However, it may be more convenient to use separately shielded
phono-type cables for each function (RX AUDIO, TX AUDIO, etc.).
In this case, the HAL PCI-EXT accessory Cable Expander is very
useful. Whether connections are made directly to the 25-pin
connector or through the PCI-EXT, it is HIGHLY recommended that
ALL cable to and from the PCI-2000 be shielded and that a
separate low inductance RF ground also be connected between one
of the rear corner screws of the IBM-PC cabinet and the radio
equipment.
2.1.1 Direct DB25 Connections
In some radio systems, it is convenient to make up one or two
multi-conductor cables that include all the necessary signals to
and from the PCI-2000. This may be particularly desirable when
transceivers with multi-pin I/O connectors are used. In this

CHAPTER 2
CONNECTIONS
Page 9
case, use a shielded, multi-conductor cable with No. 24 or 26
wire size for the system cable. The simplest hook-up involves
only one 5-conductor shielded cable (Ground, AF IN, AF OUT or
FSK, PTT, and CW KEY). A second 2-conductor shielded cable is
also desirable for connection to a tuning indicator or RTTY
scope. A typical radio system direct cable connection is shown
in Figure 3.

2.1.2 Use of PCI-EXT Cable Expander
Some receiver-transmitter systems have separate rear panel
connections for each I/O function (receive audio, transmitter
audio, push-to-talk, etc.). In this case, it may be desirable to
use separately shielded cables for each signal. The PCI-EXT
accessory provides a convenient expansion of.the DB-25 connector
to 10 phono connectors for radio connection and to a standard
DB-25 for the external modem or other serial device. The PCI-
EXT also allows rapid cable change between different transmitters
and receivers and greatly reduces the need to fabricate custom
cables. When using the PCI-EXT, be sure to include a good low
inductance ground between the PCI-EXT ground terminal and the
cabinets of the transmitter and receiver. Also, use ONLY
shielded cables for each signal connection. The common hi-fi
monaural cables and stereo cables work well for this use and may
often be purchased with connectors that match those on the
transmitter and receiver, eliminating most connector assembly.
Typical radio system connections using the PCI-EXT are shown in
Figure 4.

2.2 Tuning Indicators
An RTTY tuning indicator is a highly recommended addition to the
PCI-2000 radio system. Two slightly different tuning indicators
maybe connected to the PCI-2000: (1) a "standard" X-Y
oscilloscope or RTTY scope, or (2) an audio spectrum indicator
(such as the HAL SPT-1 SPECTRA-TUNE). Both indicators may be
connected simultaneously, if desired.
2.2.1 RTTY Tuning Scope
The RTTY scope should be connected to the MARK and SPACE outputs
to give the normal X-Y ellipse presentation. Conversely, any
standard oscilloscope with separate vertical (Y=SPACE) and
horizontal (X=MARK) can be used as a tuning indicator. The
MARK and SPACE outputs of the PCI-2000 produce audio signals with
approximately 10V P-P amplitude when the input signal frequencies
match those of the discriminator filters. Some older vacuum tube
type oscilloscopes may require additional amplification for the
horizontal (X) axis input. Be sure to use shielded cables for
all tuning scope connections. Typical scope connections are
shown in Figures 3 and 4.
2.2.2 Spectrum Indicator
An oscilloscope gives a very good RTTY tuning indicator,
preferred by many experienced RTTY operators, but does NOT give a
tuning indication for reception of Morse code. The HAL SPT-1
SPECTRA-TUNE gives an equally effective tuning indication for
RTTY and many also be used for reception of Morse code. Three
special connections are provided for the SPT-1 SPECTRA-TUNE:
Receive Audio, Audio Out, and DC Power.
Be sure to use shielded cables for all audio connections to the
SPT-1. Connections to the SPT-1 are shown in Figures 3 and 4.
2.3 Modem Connections
The PCI-2000 is a versatile addition to the Personal Computer and
provides more than the minimum connections for use with a radio
system. In addition, the serial I/O UART of the PCI-2000 may be
used directly with an external modem or computer, by-passing the
PCI-2000 RTTY modems. An added advantage of the PCI-2000 is the
internal 103/202 modem. Although this modem will normally be
used for radio communication, it may also be used in phone-line
applications if external line protection is provided ("DAA"
device).
There are two ways in which a telephone line modem may be used
with the PCI-2000: (1) use the internal 103/202 modem with
external isolation device, and (2) use an external modem
connected to the RS232 signals. Two more options are also
available for general PC use: (3) use a modem card in another
slot in the computer, or (4) use a communications card in the PC
connected to an external modem. These last two options do not

CHAPTER 2 CONNECTIONS
Page 12
involve use of the PCI-2000 but are available since the PCI-2000
may be assigned to either COM1 or COM2 serial I/O channels in the
PC. Obviously, the optimum choice will depend upon what options
and external devices you already have for the computer.
2.3.1 Use of PCI-2000 Internal Modem
If it is desired to use the internal 103/202 modems of the PCI-
2000, you should consider the following requirements:
1. The PCI-2000 does NOT include the FCC-required DAA isolation
device. You must use an approved DAA (such as the Bell CDT or
equivalent) to make a legal connection to the telephone system.
2. The PCI-2000 does NOT include a ring-detection circuit. This
feature is supplied by the DAA device. However, a "RING" or
connect/disconnect input is provided to the modem circuit
(connect = logic low, disconnect = open circuit, pulled to +5VDC
internally).
3. The PCI-2000 software does NOT support telephone line type
protocol, dialing, and other desirable phone modem features.
However, the PCI-2000 may be used with other software if the
operating parameters are first set-up with SETUP.EXE, the modem
set-up program on your HAL diskette.
4. The PCI-2000 does include FDX for either ANSWER or ORIGINATE
modes when the 103 modem option is selected. This should also be
set-up beforehand as discussed in item 3.
5. The PCI-2000 202 modem does NOT support the 75 baud reverse
channel feature of some 202 type modems.
6. Audio connections to and from the radio equipment should be
disconnected when the PCI-2000 modem is connected to telephone
lines.
7. Connections to MODEM LINE and RING must be made directly to
the PCI-2000 DB-25 I/O connector (pins 9 and 20). These
connectors are NOT available on the PCI-EXT accessory.
Typical · connections for use of the PCI-2000 103/202 modem on
telephone lines are shown in Figure 5.

2.3.2 External Modem with PCI-2000
The UART circuit of the PCI-2000 may also be directly connected
to an external modem. In this case, the PCI-2000 operates much
like any other serial asynchronous communications card. You
should, however, furnish your own telephone communications
software that utilizes the selected PCI-2000 serial I/O channel
(COMl or COM2). The external modem in this arrangement should be
connected directly to either the DB-25 connector on the PCI-2000
or to the special DB-25 on the PCI-EXT accessory.
*****************************************************************
NOTE: The DB-25 connector on the PCI-2000 does NOT follow
standard modem pin arrangement due to the large number of signals
required to support all PCI-2000 modes. If a direct connection
is required, a special cable will be required between the PCI-
2000 DB-25 and the modem. CHECK YOUR WIRING CAREFULLY!
Conversely, the MODEM DB-25 connector on the PCI-EXT accessory
DOES follow standard DTE pin arrangement and most modems may be
connected directly to this connector with standard cables.
Addition of the PCI-EXT is highly recommend when an external
modem is to be connected to the PCI-2000.

CHAPTER 3
OPERATION
Page 15
This section of the manual discusses how to use the software
supplied with the PCI-2000. A complete reading of this chapter
is of course recommended. However, section 3.1 contains an
outline-view of operation that will get the experienced computer
user going.
3.1 Getting Started
A few easy steps are required to start the PCI-2000. These steps
are much the same as you would perform for any other program and
will become very familiar after some practice.
3.1.1 How to Make Back-up Copies of the Diskette
Some PC owners seem to have confusion about how to copy the PCI-
2000 software to their own diskette. For IBM PC owners, the
following technique works well:
a. Format a new diskette that includes the DOS system
files using the FORMAT/S command. In a two-drive
system, put the DOS diskette in drive A and the new
diskette in drive B. After booting DOS, type:
FORMAT B:/S (and the enter key)
b. Copy all files from the HAL PCI-2000 diskette to the
newly formatted diskette. In a two drive system, put
the HAL diskette in drive A and the newly formatted
diskette in drive B. Then type: COPY *·* B: (enter)
All of the files on the HAL diskette will now be copied
to the new diskette. When complete, put the HAL copy
in a safe place and use the newly prepared diskette
for operation.
3.1.2 L?ading the Software
Be sure that you have the DOS system files on the copied PCI-2000
diskette. The software for the PCI-2000 is controlled by an
"AUTOEXEC.BAT" file that automatically loads the main program
called "PCRTTY". The software may be loaded using either a
"cold boot" or a "warm boot". The full procedure for a "cold
boot" is listed in Table 5. For a "warm boot", simply press ALT-
CTRL-DEL and start at step No. 4. You may also run the program
by typing "PCRTTY" in response to the system prompt.
For . experienced computer users, later versions of PCRTTY have
been designed to operate in multi-tasking environments like
TOPVIEW from IBM. This means that you can do word processing or
homework on the PC while PCRTTY monitors radio link activity.

OPERATION
TABLE 5
BOOTING THE SOFTWARE
With the PC power turned OFF, install the
PCI-2000 circuit board in the computer
as discussed in Chapter 2.
2. Insert the PCI-2000 software diskette in
disk drive "A" (top or left-hand drive in
most machines). Have you made back-up
copies? If not, do it NOW and use the
copy! See Section 3.1.1 if you are still
confused about how to copy the program to
another diskette. DON'T close the door
lever until after power is turned on.
3. Turn-on the PC power switch.
4. After the computer power is on, close the
drive door lever.
5. After the PC memory check is completed, the
disk light will come on and the screen will
request the time. Enter the time in the
normal format (hrs:mins:sec). Then enter
date as requested (mo-day-yr). (Use of
clock cards is discussed in section 3.6.4.)
6. The executive file will now call "PCRTTY"
and the title page will be displayed. Note
that a version number is displayed on this
page. Write down this number in your
manual for future reference.
7. After a short delay, the operating screen
will be displayed.
3.1.3 The HELP Page and Use of the FN Keys
Page 16
The ten ·function (FN) keys of the PC are used to set and control
many hardware and software features. A "HELP" menu page
explaining the function key uses is available at any time by
typing "ALT-H". The following tables present a complete list of
the controls available. The features will be discussed in detail
in following sections of this chapter. In the following tables,
the symbol "CR" means carriage return, or the ENTER key on most
PC-compatible keyboards.
