2. INTRODUCTION TO THE HP 82973A HP-IL INTERFACE
Congratulations! You have urchased a quality Hewlett-Packard Interface Loo
(HP-IL) card that enables you to transfer information such as
s readsheets, memos, and data files between your HP Portable Com uter and
your Deskto Com uter (the Portable-Deskto Link).
The HP 82973A HP-IL Interface also enables you to form a deskto link
between a deskto com uter and your HP-IL eri heral devices.
NOTE: This manual contains instructions for the Revision C (or later)
HP-IL Interface Card. These instructions do not a ly to cards
with revision designation A.

-3-
The HP 82973A HP-IL Interface is a owerful yet easy-to-use addition to
your deskto com uter. It enables the deskto PC to serve as:
1. A " eri heral device" on an HP-IL loo controlled by an HP Portable.
2. A "loo controller" using HP-IL eri heral devices. (If your
deskto PC runs MS-DOS 3.0 or greater, use this mode.)
If you have one interface card installed on the deskto PC, it can be
either a eri heral device or the loo controller (but not both at the
same time).
The software disc included with the interface card contains rograms and
information needed to o erate the interface. To rotect your investment in
this roduct, you should make a backu co y of the disc as soon as ossible
and then store the original disc in a safe lace. Use the co y of the
software disc for all your o erations.
To make a co y of your disc, follow the instructions in the owner's manual
for your com uter on how to care for and co y discs.
Since your rograms and information are stored on disc, you should handle
the software disc, and all discs, carefully:
* Return flexible discs to their storage envelo es immediately after
removing them from the disc drive.
* Do not bend, fold, or emboss flexible discs.
* Kee discs away from sources of strong magnetic fields, such as
magnets, wires carrying heavy currents, transformers, and
degaussers (magnetic erasers).
* Refer to the MS-DOS manual for more information about disc care.

3. INSTALLING THE HP 82973A HP-IL INTERFACE
3.1 Introduction
To install the HP 82973A HP-IL Interface in your deskto PC, follow the
instructions in com uter owner's manual. (If these instructions are
not available, consult your dealer for information about installing the
interface.) You don't need to set any system switches on the deskto PC.
CAUTION!
The interface card is shi ed in a wra ing that rotects it from
electrostatic discharge (ESD). A common exam le of ESD occurs when
you walk across a car et and get an electrical shock from touching
a doorknob. The shock you feel is a discharge.
Even if you don't feel a shock, a static discharge can occur.
To revent ESD from damaging the interface card, kee the card in its
rotective wra ing until you are ready to install it. When you are ready
to install the card, touch a grounded metal object to remove any static
charge that you might have. After grounding yourself, you can remove the
card from the wra ing and remove the rotective cover from the edge
connector. Always handle the interface card by its edges!
After you remove the interface card from its rotective wra ing and
remove the rotective cover from the edge connector, you can install the
interface card in the deskto PC.

-5-
The HP 82973A HP-IL Interface has an I/O address of 700 (hex) reset at
the factory. In most cases, you won't need to change this address. But
if another card has this address, change the address setting on either the
HP-IL interface or the other card.
If this card does not a ear to o erate, or another card does not o erate
with this card lugged into the PC, you robably need to change the address
of either card. The rest of this section describes how to change the
address of the HP-IL Interface.
NOTE: In most cases you won't need to change the address of the interface.
Therefore, you robably don't need to read the rest of this section.
To change the address of the HP-IL interface, first determine a new,
unique address, such as 218 (hexadecimal). Then:
1. Physically set the address switch on the HP-IL interface. (The
rocedure, and suggested address settings, are described beginning
on the next screen.)
2. Enter the new address in the file HPLINK.BAT. (This is described later
in this section.)
3.2 Adjusting The Address Of The Interface
Hold the interface card so the mounting bracket is to the left and the edge
connector is toward the to . The address switch is at the u er right of the
center of the board.
The address switch has eight switch segments that can be set
with a ball oint en. The designation "A10" is to the left of the switch and
the designation "A3" is to the right of it. (Ignore the rint on the switch.)
\ Edge Connector

Shown below are the switch settings for some alternative addresses:
In the table, a "1" indicates that you slide the switch segment to the
"1" osition and a "0" indicates that you slide the switch segment to "0."
The next screen shows more alternative settings.

The exam le at right shows / \ / \ |
how to set the I/O address 1 1 0 0 1 0 1 1
to 658 Hex. The range of the 1 +-+ +-+ +-+ +-+ +-+ +-+ +-+ +-+
leftmost digit is 0-7, the |H| |H| | | | | |H| | | |H| |H|
range of the middle digit is | | | | |H| |H| | | |H| | | | |
0-F, and the last digit can 0 +-+ +-+ +-+ +-+ +-+ +-+ +-+ +-+
be either 0 or 8. The card uses
only 8 bytes of I/O address s ace.
If the default address conflicts with another I/O card, you might try
to use one of the following (or any other that you wish): 688, 218,
258, 288, 658, or 200.
3.3 Changing The Address In HPLINK.BAT (For Non-Controller O eration)
HPLINK.BAT is a batch file that, among other things, tells the deskto PC
the memory address of the HP-IL interface. After altering the address on the
HP-IL interface, you need to change the address s ecified in HPLINK.BAT.
To change the address in HPLINK.BAT, ty e:
COPY CON HPLINK.BAT <RETURN>
A:CS80 nnn <RETURN>
<Ctrl> Z <RETURN>
where nnn is the three-digit hexadecimal address of the interface. For
exam le, to set the address to 218, the second line above becomes:
A:CS80 218 <RETURN>
After changing the address on the HP-IL interface, installing it, and
changing the address line in the file HPLINK.BAT, the interface is ready to
use.
If you can't determine a new address for the interface or, after consulting
your deskto PC manuals, you are unable to ro erly install the interface,
consult your dealer.

4. CONNECTING AND USING HP-IL
The Hewlett-Packard Interface Loo (HP-IL) consists of a controller
(a com uter), and one or more devices (such as disc drives and rinters)
connected in a series. All devices must be connected and switched on for
the loo to o erate. You can have u to 31 devices in a loo .
+----------+ IN <----------- OUT +----------+
| Device <------------------------------------------------< Device |
| | | |
| 2 >--------------------+ +----------------------> 1 |
+----------+ OUT -----> IN | | OUT -----> IN +----------+
+-------v----^--------+
| controller |
| |
+---------------------+
Peri heral devices are connected to your com uter (and to each other) using
HP-IL cables. A 1-meter cable is shi ed with the interface card, and one
is shi ed with each eri heral device.
The rece tacles on the interface card indicate the direction information
travels around the loo . With the deskto PC as loo controller, instructions
and data are sent from the card through the rece tacle labeled "OUT" and
are received by the card through the rece tacle labeled "IN."
When only one eri heral is connected to the interface card (the card is
installed in the deskto PC), one HP-IL cable runs from the OUT rece tacle
on the back of the com uter to the IN rece tacle on the eri heral. The
other HP-IL cable connects the OUT rece tacle on the eri heral to the
IN rece tacle on the com uter.
If you want more than one eri heral in the loo , HP-IL cables should be
connected from the OUT rece tacle on each device to the IN rece tacle on the
the next device. Re eat this rocedure until all eri heral devices are
connected.
The loo is com leted when the OUT rece tacle on the last eri heral is
connected to the IN rece tacle on the com uter. Note that EITHER the deskto
PC OR the Portable may be the loo controller at a given time--not both.
Instructions and data on HP-IL originate from the controller and travel to
the first eri heral, on to the second and continue around the circuit until
that information returns to the controller. If the information isn't
intended for a articular eri heral, it travels to the next eri heral
in the loo . When the information reaches its destination, that eri heral
res onds as directed and then asses on the information.

-9-
If you wish to s ace eri herals further from the com uter than ermitted by
the cables, connect additional HP-IL cables. The maximum distance allowed
between any two devices or a device and the com uter is 10 meters (33 feet)
with standard cables.
Standard HP-IL cables are:
HP 82167A .5 meter.
HP 82167B 1 meter.
HP 82167D 5 meters.
5. USING THE DESKTOP PC AS AN HP-IL DEVICE
5.1 Introduction
The HPLINK rogram turns a deskto PC into an HP-IL device controlled by a
Portable com uter.
Sam le +----------------+
Configuration: | HP Portable |
| (Controller) |
+------------+ +----v------^----+ +------------+
| HP 9114 | <------ OUT | | IN <------ | Deskto PC |
| Disc Drive <+----------------+ +----------------+< |
| >+----------------------------------------+> (Device 2) |
| (Device 1) | -------> | |
+------------+ +------------+
NOTE: Don't attem t to use a hard disc that was formatted with DOS 3.0
or greater as a device to be controlled by The Portable. The
Portable PLUS, however, recognizes such a disc and controls only
the other devices in the loo . The HPLINK rogram warns a user of
DOS 3.0 or greater before it makes the deskto PC a device.
HPLINK is a rogram that turns the deskto PC into any of three eri heral
devices to be o erated by an HP Portable Com uter:
* Disc Drive.
* Printer.
* Dis lay. (The dis lay o erates as a rinter.)
Before running HPLINK ensure that all HP-IL devices are connected and
turned on.

-10-
5.2 How To Run HPLINK
To run HPLINK insert the software disc in drive A and ty e A:HPLINK.
HPLINK dis lays the following selection of devices:
1: Disc
2: Printer
3: Dis lay
(E) Exit
HPLINK also dis lays the current device at the bottom of the dis lay. (The
default is "Disc Drive.") A deskto PC can act as one device at a time only.
To select a device ty e, ress the number key corres onding to the device you
want. For exam le, to use the deskto PC disc drives, ress (1). To end the
HPLINK rogram, ress (E). This returns you to the o erating system.
So far, this section has described everything you need to know to begin
using HPLINK. If you want to try running HPLINK now, ress (E) to exit from
this manual, ensure the software disc is in drive A and ty e: A:HPLINK.
The rest of this section describes more about using HPLINK. If you want more
information about how disc drives are assigned or about using the deskto PC
rinter and dis lay, you can continue with the next screen.
Note: If the deskto PC has no hysical disc drive B, you should read the
screens on using deskto PC disc drives (beginning next screen).
5.3 Using Deskto PC Disc Drives
When you select Disc from the HPLINK menu, the disc drives connected to the
deskto PC are accessible to an HP Portable. The drives are automatically
assigned drive identifiers that follow in the sequence of the existing
Portable PC disc drives.
For exam le, if you have drives A: and B: assigned on the Portable and then
run HPLINK and select Disc from the HPLINK menu, the deskto disc drives are
assigned to the Portable as drives C:, D:, and so on. To use the deskto PC
drives, ensure that the number of external drives s ecified in the Portable
system configuration is at least the number of deskto PC drives.
