O
of the PTC-860
The Telxon PTC-860 is a battery-powered hand-held computer
used to collect, store, and transmit data.
The PTC-860 automates your data collection procedures and is
custom programmed to efficiently handle your organization’s
unique data collection jobs. Options for scanning bar codes and
printing are also available.
Because the PTC-860 is custom programmed for each
organization, this manual does not include the specific
operating instructions for your organization’s unique PTC
data collection program. Operating instructions and training
are available from your organization.
The PTC’s program leads you through the data collection
procedure with a series of display messages, prompts, and
beeps. Messages tell you when you make an error and provide
information on the program or the PTC’s status. Prompts and
beeps tell you when to enter data, what type of data to enter,
and when you complete certain operations.
ᮣ Entering data
Entering data into the PTC-860 is easy. You can key in data
through the PTC’s keyboard, scan bar-code labels with a
bar-code reader, or have another device transmit data to the
PTC.
13
Download from Www.Somanuals.com. All Manuals Search And Download.
Through the keyboard
Entering data through the keyboard is similar to operating a
calculator. As you press a key on the PTC’s keyboard, the
corresponding number or letter appears on the display.
Pressing the ENTER key stores data in the PTC’s memory.
With a bar-code reader
A second method of entering data is with a bar-code reader.
When you pass the reader across a bar code the PTC is
programmed to read, the PTC and reader interpret the data
and store it in the PTC’s memory.
Via cloning or downloading
A third method of entering data into the PTC-860 is by
receiving (via cloning or downloading) the data. In cloning, one
PTC sends a duplicate copy of its programs and data to another
PTC via a data cable connected directly to both PTCs. In
downloading, a host computer sends data to the PTC either
directly (using a data cable) or over the telephone lines. When
sending data over the telephone lines, an optional accessory
such as a modem is used. The modem is connected to the PTC
with a data cable.
Once you enter data into the PTC, it is stored in files in the
PTC’s memory. Each file holds a separate group of application-
related data. For example, a PTC used to collect many types of
data (sales orders, inventory changes, and employee hours)
would store all data relating to sales orders in one file, all data
relating to inventory changes in another, and all data relating
to employee hours in still another.
ᮣ Communicating data
After collecting the data, the PTC must either transmit the
data to a host computer for processing or send it to a printer, or
both, to make the data useful to you and your organization.
14
Download from Www.Somanuals.com. All Manuals Search And Download.
Once the host computer receives the data from the PTC, it uses
that data to update its master files and records. In some cases,
the host computer may even transmit data back to the PTC,
asking you, as the PTC’s operator, to perform a new task.
ᮣ Models
This manual covers the three optical models of the PTC-860:
PTC-860, PTC-860ES, and PTC-860NI. These three models are
similar but have the following differences:
•
The PTC-860 has a wand port (used to connect bar-code
readers) on its side.
•
the PTC-860 model but is specially sealed for use in
harsh environments. The unit does not have a wand
port for connecting bar-code readers. Wands must be
connected through the PTC’s 25-pin connector.
•
The PTC-860NI (Non-Incendive) is designed for use in
hazardous locations. (Refer to the “Use in hazardous
locations” section on page 9 for the locations in which
the unit is approved for use.)
No a ccessor ies a r e a p p r oved for u se w ith th e
P TC-860NI in h a za r d ou s loca tion s. However, all
PTC-860 accessories can be used with the unit in
non-hazardous locations. Like the PTC-860ES, the
PTC-860NI does not have a wand port; bar-code readers
must be connected through the unit’s 25-pin connector.
Unlike the other two PTC-860 optical models, which can
use either an AFAT nickel-cadmium battery pack or AA
alkaline batteries, the PTC-860NI can be used with only
an AFAT nickel-cadmium battery pack.

P
Figure 2 shows the parts of the PTC-860.
ᮣ 25-pin connector
On the top of the PTC is a female RS-232-type 25-pin connector
for accessories and communication. A cable or the connector on
the bottom of some accessories plugs into this connector to
communicate with the PTC. The 25-pin connector can also be
used to attach the PTC’s battery charger.
The connector is between a slot, a screw, and a latch plate,
which are used to hold accessories in place when they are
connected directly to a PTC.
ᮣ Application flash EPROM
An application flash EPROM is an electronic component
soldered into the PTC-860. It contains the PTC’s data collection
program and determines the PTC’s key functions, the display
prompts and messages, and how and when the PTC prints or
transmits data.
You can erase the application flash EPROM and then
reprogram it with a new program from the host via software in
the PTC’s operating system.
For instructions on how to erase and reprogram an application
flash EPROM, refer to the Guide to the FLASH Utilities (TCAL
or MS-DOS Version). See Appendix B for this manual’s part
number.
CAUTION! Do not attempt to erase or reprogram the
PTC-860NI’s application flash EPROM in a hazardous
location. This procedure is approved for use only in a

ᮣ Backup battery
All models of the PTC-860 have a built-in backup battery. The
backup battery provides enough power to protect data stored in
the PTC’s memory when the main batteries are being changed
or if they run out of power.
A switch inside the PTC, accessible through the battery door,
lets you turn on the backup battery. The PTC-860 is shipped
from the factory with this switch turned off to conserve the
backup battery power.
Note: Once you turn on the backup battery by pushing down
on the backup battery switch, do not attempt to reraise the
switch. It is meant to stay down permanently.
If your PTC shows a “Backup Battery Fault” message when
you turn on the PTC, either turn on the backup battery or
have the backup battery replaced. (Do not attempt to replace
the backup battery yourself; contact your Telxon service
representative for assistance!)
CAUTION! Do not store a PTC-860 for over two months
without charging the battery pack or replacing the alkaline
batteries. Otherwise, both the primary batteries and the
backup battery will drain, and any data and programs
loaded in the PTC’s memory will be lost.
ᮣ Bar-code reader (optional)
The PTC-860 unit (not including the PTC-860ES and
PTC-860NI units) may have an optional bar-code reader
that plugs into the wand port on the side of the unit. If your
PTC-860 unit was ordered with a pencil-wand bar-code reader,
it has a holder for the reader attached to its side.
Bar-code readers are available for the PTC-860ES and
PTC-860NI but must be connected to the units through the
25-pin connector.

CAUTION! Do not use a bar-code reader with a PTC-860NI
in a hazardous location. Accessories are approved for use
with the PTC-860NI only in non-hazardous locations.
The bar-code reader lets you enter data into your PTC by
passing the reader across bar-code labels (scanning). Your
PTC’s data collection program determines the types of bar-code
labels you can read.
ᮣ Battery charger
The battery charger is used to recharge the nickel-cadmium
battery pack in the PTC. The charger for the PTC-860 has a
25-pin connector.
CAUTION! Do not charge a PTC-860NI’s battery pack in a
hazardous location. Accessories are approved for use with
the PTC-860NI only in non-hazardous locations.
ᮣ Battery compartment
The PTC-860 and PTC-860ES come from the factory with an
AFAT nickel-cadmium battery pack or four AA alkaline
batteries in a plastic battery case. The PTC-860NI comes with
the AFAT nickel-cadmium battery pack.
The battery pack charges in 14 hours.
When the battery pack or alkaline batteries are weak but not
weak enough to stop the PTC from operating, a low-battery
message displays, the PTC’s beeper sounds a warning beep,
and the red low-battery light comes on.
Note: When the PTC’s battery pack or alkaline batteries
become too weak to operate the PTC, the unit automatically
shuts off. In this event, charge the battery pack or replace the
alkaline batteries immediately.
CAUTION! Do not store a PTC-860 for over two months
without charging the battery pack or replacing the alkaline
batteries. Otherwise, your data and programs will be lost.

communication cradle and are used to recharge the PTC’s
nickel-cadmium battery pack.
ᮣ Display
The PTC-860’s display screen shows the information you type
or scan into the PTC and messages and instructions from the
PTC or the host computer. The screen is a supertwist liquid
crystal display (LCD).
The display can show up to sixteen lines of information, each
line sixteen or twenty-one characters long. In addition, the
display is graphics supported, which allows a variety of
character sets to be displayed and enables the 16-line display
to emulate an 8-line display.
Above the display are two light-emitting diode (LED)
indicators. The green LED glows when the battery pack is
being charged. The red LED glows when the batteries are low.
The low-battery LED works only when the PTC is turned on.
ᮣ Elastic strap
A wide elastic strap on the back of the PTC is used as a hand
strap. It secures the PTC to the palm of your hand, making it
easier to hold onto the PTC when you are using it.
ᮣ Keyboard
The keyboard on the PTC-860 can have fifty, forty, or
twenty-four keys. Each keyboard has two different types
of keys: data keys and function keys.
26

Data keys are the letter and number keys, A-Z and 0-9. You use
them to type data into the PTC. Function keys include the
F1-F5, CLEAR, ENTER/YES, and SEND keys. These keys may
have different labels on your PTC. They are used to perform a
special procedure or function. For example, your program may
use the SEND function key to transmit the PTC’s data to the
host computer.
ENTER/ YES key
How you use the ENTER/YES key depends on your
organization’s data collection program. Usually you press this
key to tell the program that you have finished typing data,
have finished an operation, or want the PTC to begin an
operation, such as sending data to the host computer.
ON/ OFF key
Pressing this key turns the PTC on or off.
SHIFT key
On a 50-key keyboard, the SHIFT key activates only the
function keys labeled on an overlay that slips over the
keyboard. The numeric keys are always available.
On a 40-key or 24-key keyboard, the SHIFT key shifts between
the numeric and alphabetic keyboard and also activates some
of the function keys your program uses. These keys are labeled
on the overlay.
Note: Your data collection program may turn off certain keys
at times during the program to prevent you from accidently
erasing data or ending an operation. The PTC beeps when you
press a key the program has turned off.

ᮣ Keyboard overlay
The keyboard overlay is a small sheet of plastic cut out to fit
over the PTC’s keyboard. Labels for the special function keys
used by your organization’s data collection program are printed
on the overlay.
ᮣ Optical coupler
On the back of the PTC-860 is a small red window. Behind the
window are five LEDs that the PTC can use to communicate
with your host computer. Instead of sending data in the form of
electronic signals through the RS-232 connector, the PTC sends
the data in the form of pulses of light to a similar coupler on an
optical communication cradle. The cradle then converts the
pulses of light into electronic signals and transmits them
directly to the host computer or over the phone lines. The
cradle can also send data to the PTC via the optical couplers.
ᮣ Screwdriver
A small screwdriver is part of the clasp on the ends of the
elastic strap. Use the screwdriver to loosen the screws holding
the battery door in place when you need to change the batteries
in the PTC-860.
ᮣ Wand port (PTC-860 only)
Optional bar-code readers plug into a wand port on the side of
the PTC-860 unit. (PTC-860ES and PTC-860NI units do not
have a wand port.) If your PTC-860 unit was ordered without a
bar-code reader, a plastic plug covers this port. Do not remove
the plastic plug except to add a bar-code reader to your
PTC-860 unit. (For instructions on how to attach a bar-code
reader to your PTC-860 unit, see page 33.)

ᮣ Automatic off
To conserve battery power, the PTC-860 turns itself off
automatically after approximately 1 minute of inactivity. The
exact length of time depends on the program.
ᮣ Automatic return at on
When you turn the PTC-860 off (or when the PTC-860 turns
itself off), it remembers where it was in the data collection
program. Then, when you turn the PTC-860 back on, it returns
to that same point in the program. You do not need to review
what you have done or perform any other start-up function to
find your place.
ᮣ Backlight
The backlight lights up the display to make information
readable in low light. The backlight may or may not be
available to you, depending on your organization’s data
collection program.
If the backlight is available, you can turn it on by pressing a
key on the PTC’s keyboard, typing in a command, or making a
choice from a list on the PTC’s screen. Once it is turned on, it
turns itself off after a predetermined amount of time to

ᮣ Beeper
The PTC-860’s internal beeper is used by the PTC and your
data collection program to warn you of problems or to prompt
you to take an action. For example, if your program has
temporarily turned off a key, the PTC beeps if you press it.
ᮣ Clock
The PTC-860’s built-in clock keeps track of the date (month,
day, year, and day of the week) and the time (hours, minutes,
and seconds). The clock operates continuously.
How the clock is used depends on your data collection program.
For example, the PTC-860 can use the clock to show the date
and time on its display or to direct a printer to place a time
stamp on a report.
ᮣ Memory
The PTC-860’s internal memory stores your organization’s data
collection program and the data you type into the PTC.
The amount of memory in your PTC determines how much
data you can type in before you have to send it to a host
computer or print it. Various amounts of memory are available
from Telxon, and the amount actually installed in your PTC
has been determined by your organization’s needs.
ᮣ Power backup system
The PTC-860 contains a lithium cell that is used as a backup
energy source when the main batteries are removed or are too
weak to provide adequate power. If used continuously, the cell
lasts twenty days. If the main batteries are always left in the
PTC and charged, the cell has a minimum five-year life.

data
The PTC-860 is able to communicate with other computers and
PTCs. How it communicates and how it is connected depends
on your data collection program and how your PTC-860 is
equipped.
The PTC-860 can be set up for either one-way or two-way
communication. It can communicate through its optical coupler
or through its RS-232-type 25-pin connector.
The PTC-860 can be connected directly to a host computer or
another PTC, or it can be equipped with an optional modem to
communicate over telephone lines.
ᮣ Using the optical coupler
The PTC-860 has an optical coupler on the back of its unit. The
optical coupler converts electronic signals inside the PTC into
pulses of light that can be detected by the CS-860 Optical
Communication Station or the MCO-860 Four-Bay Cradle.
When the PTC-860 is placed in a cradle, an optical coupler on
the cradle senses the pulses of light from the PTC and converts
them into electronic signals for direct communication to the
host computer or, with an external modem, for transmission
over telephone lines.
Likewise, the cradle can communicate back to the PTC through
the optical couplers.
36
Download from Www.Somanuals.com. All Manuals Search And Download.
Communicating through the optical coupler requires the use of
an optical communication cradle. See the Guide to the CS-860
Optical Communication Station or the Guide to the MCO-860
Four-Bay Cradle for instructions.
CAUTION! Do not use a PTC-860NI with a CS-860 or an
