PTC-2134 Overview
The PTC-2134 is a rugged, SC400-proc essor-powered,
PC-compatible,pen-based portable teletransaction
computer (PTC). It is used to collect, store, and
transmit data. A passive stylus is the PTC’s primary
input device. The stylus allows the user to make
selections on the screen or to write on the screen in
much the same way as on pap er with an ink pen. In
general, the PTC is operated by using the stylus to
write directly on the screen to fill in forms, to check
off boxes, or to make choices from menus.
An orga nization’s specific app lication pro gram that
was developed for its needs will determine the actions
to be taken by a user. S ee the manuals or instructions
provided by your organization for application details.
Through its pen operating environment, the PTC
recognizes the written letters and numbers on its
screen and translates them into a form that can be
used and stored in the PTC.
3
Processor
The PTC’s 100-MHz AMD Elan SC400 microprocessor
is fully IBM PC compatible. It provides exceptional
processing speed and is designed for low power
consumption.
6 PTC-2134 User’s Guide
Operating Systems
Operating Systems
The PTC-2134 may use the MS-DOS 6.22, Windows
95, or Windows CE operating system. PenRight! is a
separate pen operating environment that runs on top
of the operating system and allows the PTC to
recognize screen taps as well as written letters and
numbers.
Applications
The Symbol Pen-Based SC 400 Software D evelopment
Kit is available to assist in the development of penbased applications for the PTC. Contac t your Symbol
representativefor more information.
Memory
The PTC-2134 has two types of m e mory: read-only
memory (ROM) and r andom access memory (RAM).
ROM
The PTC-2134 comes with 512 kilobytes (KB) of readonly memory. It contains the Basic Input/Output
System (BIO S) for MS-DOS/Windows 95 o r the
bootloader for Windows CE.
RAM
The PTC-2134 contains 4, 20, 36, o r 64 megabyte s
(MB) of random access memory. RAM is used to store
data that is required by the PTC while it is running.
One MB of RAM is reservedfor running the operating
system and the application.
RAM data may be easily read, written, and changed.
It is also volatile. All data in RAM will be lost if the
PTC’s battery pack and bridge battery becomes fully
depleted or if the PTC is reset.
PTC-2134 User’sGuide 7
Chapter 3 ConfiguringTN-3270/5250
During normal operation, the PTC’s advanced power
management (APM) feature automatically protects
data in RAM and saves the user’s place in the
application.
Display Options
The PTC-2134 has a VGA monochrome liquid crystal
display (LCD) that can show up to 16 shades of gray,
and features a resistive touch panel digitizer. The
PTC-2134 i s available w ith either a transmissive or
transflective display (depending on the environment
in which the PTC will be used).
Transflective Display
A transflective display uses reflected ambient light to
produce viewable display images. It is ide al for use in
outdoor applications. For indoor use, the PTC’s
backlight may be used to optimize the display
visibility i n low lighting or under fluorescent lights.
Transmissive Display
A transmissive display does not reflect ambient light
and is intended for indoor use only. It requires the
backlight to be on at all times. The transmissive
display generally produces brighter images than
transflective displays, but consumes more battery
power.
8 PTC-2134User’sGuide
Digitizer
Digitizer
The PTC-2134 features a resistive touch panel
digitizer, which is mounted above the display. The
digitizer enables the PTC to recognize data entered
with a passive stylus. It also has a palm reject
feature, which prevents accidental activation of the
unit by casual hand or fingercontact.
Data Entry Methods
Data may be entered into the PTC-2134 in a variety of
ways. Each method is discussed below.
Data Entry Via the Stylus
As a pen-based computer, the PTC-2134is ideal for
forms-based data gathering. The PTC’sstylusmaybe
used to select menu options, to write in the fields of a
form displayed on the PTC’s screen, or to check off
items on a list. The PTC may also be equipped with an
option that captures signatures onto electronic forms
(for example, when a delivery is made or an order is
placed).
Data Entry Via the Keyboard
Caution: Do not connect a keyboard to
a PTC installed in the SC/
VC-2X34 cradle.
Data may also be entered into the PTC via an
external PC/AT key board. The keyboard connects to
the PTC via an optional serial/keyboard Y adapter
cable.
PTC-2134 User’sGuide 9
Chapter 3 ConfiguringTN-3270/5250
Data Entry Via the Laser Scanner/Bar Code Wand
Entering data may also be accomplished with the
PTC’s optional laser scanner module, an external
laser scanner, or a bar code wand. When scanning a
1D bar code, the PTC and the scanner/wand interpret
thedataandstoreitintothePTC’s memory. See
Appendix E on p. 85 for instructions on using the
scanner/wand and for a list of supportedbar codes.
Data Entry Via the Magnetic Stripe Reader
The PTC’s optional magnetic stripe reader module is
designed to read information embedded in the
magnetic strip on the back of credit cards or debit
cards.
Data Entry Via the Radio
The PTC may be configured to interface with a wide
area network (WAN).
Refer to the section titled “Radio” on p. 12 for further
information on radio communication.
10 PTC-2134 User’sGuide
Data Storage
Data Storage
Data entered into the PTC may be storedin the PTC’s
RAM, on an internal compact flash hard disk drive, on
an optional auxiliary storage card, or on a removable
PCMCIA solid state data card.The PTC’s internal
solid state compact flash hard disk drive stores the
unit’s operating system. The PTC’s application
program and data entered by the user may reside in
compact flash or on a factory-installed solid state or
rotating ATA drive (auxiliary storage card).
PCMCIA data cards are credit-card-size memory
cards that are used much as floppy disks are used in a
desktop computer. The PTC-2134 has two useraccessible PCMCIA slots that can accept two Type II
cards (one per slot) or one Type III card. Each Type II
card occupies one slot, and Type III cards, which must
be inserted into slot 1, occupy both slots.
The number of available PCMCIA slot s is dependent
on the PTC’s factory configuration options. For
example, an auxiliary storage ca rd or a field-installed
radio card uses one or both PCMCIA slots, depending
on the card type.
PTC-2134 User’sGuide 11
Chapter 3 ConfiguringTN-3270/5250
Communication
Cradle Port
The PTC’s cradle port allows direct connection to an
optional single-bay/vehicle cradle. The cradle pro vides
both communication and battery pack charging.
For more information, see the documentation shipped
with the cradle.
IrDA Port
The IrDA 1.0 port allows the PTC to communicate via
pulses of infrared light to and from other IrDAcompliant devices, such as printers or host systems.
Radio
A Type III field-installed radio (optional) occupies
both of the user-accessible PCMCIA slots.
The PTC-2134 may be ordered with an internal
factory-installed radio or with the radio-ready feature.
A radio-re a dy unit enables a field-installed Type II o r
Type III 2.4-GHz radio to be inserted into one of the
PTC’s PCMCIA slots. Units with int er nal radios or
the radio-ready feature are shipped with antennas.
The PTC may be equipped with either a local area
network (LAN) radio or a wide area network (WAN)
radio.
LAN Radio Options
• 2.4-GHz direct-sequence 802.11-compliant
spread spectrum radio.
• 2.4-GHz frequency-hopping 802.11-compli ant
spread spectrum radio.
12 PTC-2134 User’sGuide
Communication
Spread spectrum radios allow the PTC to communicate interactively in real time with a host computer
on a radio-based local area network. They provide
secure, interference-free communication and do not
require a license for operation.
WAN Radio Options
A wide area network (WAN) is a radio network that
supports data commun ications across a broad area,
such as a city, a state, or nationwide.
No license is required to operate a WAN radio in the
U.S. or Canada, but a subscription to the corresponding radio network (or another DataTAC network) is
required before the r adio may be operated.
DataTAC Radio
A DataTAC radio allows the PTC to communicate via
awideareaDataTACcommunicationnetwork.
Mobitex Radio
A Mo bitex radio allows the PTC to communicate via
the wide area Bell-South Wireless Data digital
communication network.
CPDP Radio
A Cellular Digital Pa cket Data (CDPD) radio allows
the PTC to communicate via the analog cellular
telephone infrastructure. This radio can send data via
existing cellular chan nels in bursts at 19.2 Kbps.
The PTC’s application program controls the radio.
Refertoyourapplication’s manual for d etails on using
the radio to transmit and rece ive data.
The PT C uses its radio to communicate with a host
computer. Via the radio, the PTC can send data to the
host, and the host can send data and instructions to
the PTC.
PTC-2134 User’sGuide 13
Chapter 3 ConfiguringTN-3270/5250
Serial/Keyboard Connector
So long as the PTC is installed in the SC/VC-2X34
cradle, the serial/keyboard Y adapter cable cannotbe
used with the PTC.
A built-in 15-pin connector allows the PTC to connect
to standard serial devices and to an external PC/AT
keyboard.An optional serial/keyboardY adapter c able
is required to make these connections.
Refer to Appendix B on p. 77 for cable part numbers.
Power
AC Adapter
A 15-VDC, 2.7- or 3-A AC adapter provides power to
recharge the PTC’s lithium-ion battery pack and
bridge battery. The adapter connects to the PTC’s
power jack and to an electrical outlet via an AC power
cord. The adapter has a special connector that accepts
a wide range of AC cords that supplies an input
voltage between 100 and 240 volts AC at 50/60 Hz.
Note: Use the AC adapter suppliedby Symbol
with the PTC. Using any other adapter
may damage the PTC.
Some activities, such as using the WAN radio, require
more power than the adapter can provide; this extra
power is supplied by the battery pack.
When the AC or vehicle adapter is attached to the
PTC, the unit draws most of its power from the
electrical outlet or a vehicle’s power source, not from
the PTC’s battery pack. As a result, the PTC may
remain o n and be operated while its battery pack is
being fast charged.
14 PTC-2134 User’sGuide
Battery Pack
Note: Removal of the battery pack will drain
the bridge battery (even with the unit
suspended).
Operating power for the PTC-2134 is provided by a
rechargeable lithium-ion batte ry pack. The battery
pack may be charged via an AC adapter, a vehicle
adapter, a single-bay/vehicle cradle, or a four-bay
batterycharger.The amount of time t hat the PTC can
operate on a fully charged battery pack depends on
the features and devices used and on the time that the
PTC spends communicating with the host computer.
The more the radio, backlight, serial port, IrDA port,
PCMCIA slot(s), hard disk drive, and optional
expansion modules are used, the sooner the battery
pack will run out of power.
Bridge Battery
Note: Always suspend the PTC before
removing the battery pack.
Power
Refer to Chapter 11 on p. 55 for information on
conditioning the bridge battery.
An internal rechargeable nickel-cadmium bridge
battery provides power to protect data stored in the
PTC’s RAM when the main battery pack is being
replaced o r if the main battery pack runs out of
power. Once th e main battery has been fully
discharged (and is left in the unit), the bridge battery
may protect t he PTC's memory for as long as 24
hours.
The bridge battery is recharged automatically when
the main battery pack is recharged, if the main
battery is being charged while it is in the PTC. The
bridge battery’s condition is checked each timethe
PTC is resumed.
Note: The bridge battery is recharged by
simultaneously recharging the main
batterywithinthe PTC only.
PTC-2134 User’sGuide 15
Chapter 3 ConfiguringTN-3270/5250
Vehicle Adapter
A 15-VDC, 2.7-A vehicle adapter (optional) may be
used to recharge the PTC’s lithium-ion battery pack
and nickel-cadmium bridge battery. The adapter
plugs into the PTC’s power jack and into a vehicle’s
cigarette lighter socket.
Note: Use the vehicle adapter supplied by
Symbol with the PTC. Using any other
adapter may damage the PTC.

Sleep States
The PTC goes into a sleep state if it is not used for a
period of time or if it is suspended using the Resume
button. In the sleep state, the PTC turns off portions
of its internal electronicsto conservepower. The PTC
has two stages of sleep: Standby and Resume.
Standby
Standby begins after a period of inactivity
(programmable). During this stage, the PTC’s screen
goes blan k, the backlight turns off, and other
subsystems inside the PTC may slow down or turn off
to conserve power. The PTC’s Status LED blinks
slowly to indicate that the PTC is in Standby mode.
The application program running at the time is
suspended, and any data in RAM is protected. To
wakethe PTC fromthe Standby mode, touch the
display screen with the stylus.
Suspend
Suspend begins (1) after the Standby counter
reaches zero, or (2) if the Resume button is pressed
while the unit is on. This stage turns off additional
hardware elements and provides only minimal
memory refresh operations. The Status LED and the
PTC turns off.
The time requirements of PTC inactivity for either
sleep state is user-defin able. Consult the PTC-2X34
Software Guide and the documentation provided with
the Symbol Pen-Based SC400 Software Development
Kit for programming instructions.
