Introduction
The HP 82163 Video Interface provides video display capabilities for your calculator or computer system
through the Hewlett-Packard Interface Loop (HP-IL). This manual describes the operation of all versions
of the HP 82163. These versions-which are identified by the suffix to the model number-differ
according to the antenna connectorand TV channel used in the country wherethe unit is sold.·
The video interface is typically co ntroll ed by your calculator or computer through its HP-ILcapabilities or
Hp ·IL extensions. Therefore, you should refer to the owner's manual for your computer, calc ul ator, or
HP·IL extension for operating information.
Your HP 82163 Video Interface is packaged with the following accessories:
• One HP-IL
cab le.
• One Be adapter.
• One TV /monitorcable.
• One switch box
(i nside the U.S.A.) or one cable ada p ter (outside th e U.S.A.).t
Optional accessories and specifications arelisted in appendix B.
Installation
Your HP 82163 Video I nterface is ready to use with your system after co nn ect ing power to it, j oining it
with an HP-IL system and connecting it to a TV or monitor.
Power
Power for the HP 82163 Video Interface is provided by the ac adapter . To co nn ect it to the interface, first
plug it into an ac outlet, then insert the adapter plug into the powerreceptacle at the rear of the interface.
HP-IL Connections
The Hewlett-Packard In te rf aceLoop ca n con sist of several peripheral devices a nd a co ntroller (calcul ato r
or computer). The devices ma y be connected in any order-but all of the interface cables must form a
continuous loop. All connections are designed to ensureproper orientation.
.Thi amanuaispecifies the TV channel used by the HP 82163A.which is the version designed for opera ti on in the U.S.A.The addend um
card included with o the rversions specifies theTV channel used by tho se versi on s.
tThe switch box snd c sble adapterare used to connectthe video inte rf ace to a TV. However, a TV c an 't be used with the video interface
in certain countries; therefor
e, in those count ri es. a switch box or cable adapter is not included. (Refer to the addendum card supplied
with your
un it to determine ifyou cannotuse a TV .)

6
To connect the HP 82163 Video Int erfa ce to the loop, first tum off the controller. Then, simplydisconnect
the loop in one place and connect th e video interface in that place. (In some situations the video interface
might be
the only peripheral in the loop.)
Note : The system's operation may be disrupted when the loop is disconnected.
MonitorConnections
To connect the HP 82163 Video Interface to a monitor, insert ODe end of the TVI monitor cable into the
MONITOR jack on the video interface and the other end into the input ja ck on the monitor.
Note: Some monitors may require special adapters. Refer to the specificati ons for your monitor to
determine what type of adapter, if any, may be needed .
Television Connections
Inside the U.S.A. To connect the interface to a television set, first connect the switch box to the TV,
then connect
the video interface to the switch box. The switch box allows you to have the video interface
and the VHF antenna co nn ected to the TV at the same time so that you can simply switch between
viewing normal programs and usingthe interface.
To connect the switch box to the TV, disconnect the VHF antenna wires from the VHF screws on the TV,
then attach the antenna wires from the video interface to the screws. If you want to connect the VHF
antenna to the switch box, loosen the screws through the access hole on the end of the switch box, insert
the wires from the VHF antenna through the slot on the underside ofthe switch box,slide the wires under
th escrew heads, and tighten the screws.
• Certain video m oniton can be co nn ected in 8 ae ries toreceive the n me I lin a! from the video interface. For more information. refer to
your monitor o
wner '. manual.

7
To connect the interface to the switch box, plug the end of the TV/monitor cable into the TV jack on the
video interface, then insert the otherend into the phono jack on the switch box.
When using
the video interface, the switch on the switch box should be set to INTERFACE. When
viewing normal television
program., the switchshould be .et to TV.
Outside the U.S.A. To connectthe video interface to a television, first insert the TV Imonitor cableinto
the TV jack on the video interface, then attach the cable adapter to the other end of the cable. Plug the
adapter end into the input jackon the TV.(Other .pecial adapter. may be required in certaincountri ... )
Note: The HP 82163A Video Interfaceis sold in countries that use the same television standard as the
U.S.A. If you have the HP 82163A, you should follow the instructions under Inside the U.S.A.
Television Tuning
Inside the U.S.A. When using a television with the interface, it must be tuned to channel 3.
Outside the U.S.A. The TV channel u.ed by the interfacedepends upon the country in which it is sold.
Refer to
the addendum card included with your unit todetermine which channel to use.
Operation
The video interface is ready to u .. when it has been connected to a power source, connected to a TV or
monitor,· and connected to a Hewlett-Packard Interface Loop. It will then accept Hp · IL messages and
respond to many of the print commands issued by your calculator or computer through its HP·IL
capabilities or extensions. More .pecifically,
it display. data bytes sent toit, except for tho .. contained in
recognized e.cape .. quences. (Escape sequenc .. are de.cribed on page 9.) Appendix A describes how to
verify proper operation.
Technical Description
The previous .ection. explained the ba.ic operation of the HP 82163 Video Interface. Thi •• ection
di.cu .... some ofthe more d.tailed aspects of operating the interfac•.
Throughout this section, the term "di.pl ay " refers to the screen of the TV or monitor to which the
interface is connected. It al.o refer. to the operation of printing data on the display.
Internal Design
Character 8et. The HP 82163 Video Interface feature. 95 displayable characters and 4 nondisplayable
control characters,
each with a corresponding code number shown in the table below.
• Theinterface will function normally without actually being connected to 8 TV or monitor.

The video interface features top-around scrolling. The first line of memory will follow the last line of
memory onto the screen in a repeated roll-up operation . The last line will follow the first if a roll-down
operation is continued.

On Screen
Most controllers perform a specified operation by automatically sending a preprogrammed sequence of
Hp·IL messages around the interface loop. You would not be using the actual Hp·IL messages in this
case, but rather you would be using the HP·IL capabilities built into your calculator, computer, or Hp·IL
extension. This section describes how the HP 82163 Video Interface responds to the individual Hp·IL
messages.
The video interface operates according to information it receives on the interface loop. Specifically, it
responds to the standard HP·IL messages (listed on page 10), including special Data Byte messages (in
the form of escape sequences,listed on page 10) that are interpreted as instructions.
Startup Conditions. The video interface is automatically turned on when the ac adapter is plugged into
it. While the ac adapter is plugged in, the interface retains its display memory whether or not the TV or
monitor is turned on or connected.
When the video interface is first connected to its powersource and is linked with HP-IL, it is in an inactive
mode and its default Hp·IL address is set to 3. (In most applications this default address isn 't used , since
controllers usually assign addresses to loop devices.)
Escape Sequences. The HP 82163 Video Interface responds to 14 escape sequences. An escape sequence
is a string of characters that is sent out on the loop as a series of Data Bytes and interpreted as a special
instruction by the device receiving it. An escape sequence always starte with'" (escape)-code number
27- and is followed by one or more characters that define the instruction. Escape sequences are used by
the video interface to position the cursor, scroll through display memory, and clear the display .
Many different escape sequences can be passed through HP-IL; however, the video interface responds to
only a few of these. When the interface receives an escape sequence that it does not recognize, it displays
all but thefirst two characters in the sequence. Escape sequencesrecognized by the interface are shown in
the following table.
