Disposing of nickel-cadmium batteries
.
Nickel-cadmi um batteries contain c h em ically active materials
that are hazardous to t he environment; therefore, t hey s ho uld
be disposed of properly. Never attempt to incinerate a
nickel-cadmium battery; doing so could cause it to explode.
Telxon urges you to contact the Environmental Protection
Agency, the Department of Natural Resources, a local
hazardous waste disposal agency, or the Telxon Customer
Support Center for assistance prior to disposing of your
nickel-cadmium batteries.

of the PTC-860
The Telxon PTC-860 is a battery-powered hand-held computer
used to collec t, 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. Optio ns for sc anning bar codes and
printing are also available.
Because the PTC-860 is custom programmed for each
organization, this manua l d oe s not inc lud e t he sp ecific
operating instructio ns 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. Messag es tell you when you ma k e 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 operati ons.
©
Entering data
Entering data into the PTC-860 is e as y. 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
Through the keyboard
Entering data through the keyboard is similar to operati ng 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 comput er s ends data to the PTC ei ther
directly (using a data cable) or over th e t elephone lines. When
sending data over the tele phone 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 applicationrelated data. For example, a PTC used to collect many types of
data (sale s orders, inventory changes, and empl oy ee hours)
would store a ll data relating to sales orders in one file, all data
relating to invento ry c hange s in another, and all data relating
to employee hour s in still another.
©
Communicating data
After collecting the data, the PTC must either transmit the
data to a host c om puter for processing or send it to a printer, or
both, to make the data use ful to you and your organization.
14
Once the host co mputer receives the data from the PTC, it uses
that data to update its master files and records. I n s o m e cases,
the host computer m a y even transmit data back to the PTC,
asking you, as the PTC’s operator, to perform a new task.

Models
This manual covers the thr ee op tical 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-860ES (Environmentally Sealed) resembles
the PTC-860 model but is specially sealed for use in
harsh environments. The unit do es not have a wand
port for connecting bar-code readers. Wands must be
connected through the PTC’s 25 -pin c onne ct or.
•
The PTC-860NI (Non-I ncendive) is designed for us e in
hazardous loca tions. (Refer to the “Us e in hazardous
locations” section on page 9 for the locations in which
the unit is approved for use.)
No accessories are approved for u se w ith the
PTC-860NI in hazardous locations. However, all
PTC-860 accessories ca n be used with the unit in
non-hazardous locations. Like the PTC-860ES, the
PTC-860NI does not have a wa nd p or t; b ar-code readers
must be connected through the uni t’s 25-pin connector.
Unlike the other tw o PTC-860 optical mo dels, which can
use either an AFA T nickel-cadmium battery pack or AA
alkaline batteries, the PTC-8 60 NI c an be used with only
an AFAT nick el-cad mium ba tter y pack .

Backup battery
All models of the PTC-860 have a built-in backup battery. The
backup battery provides enough power to pr otect data stored in
the PTC’s memor y when t he m a in batteries are being changed
or if they run out of power.
A switch inside the PTC, accessible through the ba tt er y 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 repl ac e
the backup battery yourself; contact your Telxon service
representative for assista nce!)
CAUTION! Do not store a PTC-860 for ov er two m onths

Keyboard
The keyboard on the PTC-860 can have fifty, forty , or
twenty-four ke y s. Each keyboard has two different types
of keys: data keys and function keys.
26
Data keys are the let ter and num ber keys, A-Z and 0-9. You use
them to type da ta into the PTC. Funct ion keys include the
F1-F5, CLEAR, ENTER/YES, and SEND keys. These keys may
have different labe ls on your PTC. They are used to perfor m 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 labe le d 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 ke ybo ar d a nd a lso ac tivates some
of the function keys your pr ogram 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 end ing an operation. The PTC beeps whe n you
press a key the program has turned off.

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 com m uni cate
with your host computer. Instead of sending data in the form of
electronic signals through the RS -2 32 connector, the PTC sends
the data in the form of pulses of light to a similar coupler on an
optical communication cradle. The cr adle then converts the
pulses of light into electronic signals and transmits them
directly to the ho st computer or over the phone lines. The
cradle can also send data to the PTC via the optical couplers.

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 tra ck of the date (month,
day, year, and day of the w eek) and the time (ho u rs , minutes,
and seconds). The clock operates continuo usly.
How the clock is used depends on y our data collection program.
For example, the PTC-860 can use the clock to sh ow 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 yo ur organization’s data
collection prog ram and the data you type into the PTC.
The amount of mem ory in your PTC determines how much
data you can type in befor e yo u 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 use d a s a b ac k up
energy source when the m a in batteries are removed or are too
weak to provide adeq uat e p owe r. If used continuously, the cell
