PTC-2134 Overview
The PTC-2134 is a rugged AMD™SC400
processor-powered, pen-based Portable
Tele-transaction Computer (PTC). It couples standard
PC technology with Symbol’s expertise in data
collection and radio technology to provide a f lexible,
high-performance portable system.
This section of the manual provides a basic overview
of the PTC-2134’s software environment, including
brief discussions of
•thesystemBIOS,
• the operating system and applications,
•thesoftwarekernel,
• the PenRight! operating environment,
• power management, and
• software development kits (SDKs).
PTC-2134 DOS Software Guide 1
Chapter 3 Configuring TN-3270/5250
Functional Overview
The PTC-2134 uses a PC-type software architecture
consisting of three major software layers:
•BIOS(Basic Input/Output System)
•OperatingSystem
• Application
BIOS
Application
Operating S ystem
BIOS
Hardware
The BIOS is the lowest software layer and typically
exists i n ROM memory.It pr ovides basic input/output
services for the system and an insulating interface
between the upper software layers and the hardware
layer.
The PTC-2134 uses a customized version of the
Phoenix™ BIOS to support PTC-2134 hardware
features. To achieve this level of supp ort while
maintaining PC compatibility, a system extension
called the Symbol BIOS, or TBIOS, is used.
TBIOS is a method for expanding the BIOS functions
without reserving a function number thatcould be
used by another application. This is accomplished by
forcing the TBIOS code to r eside with standard BIOS
code, but providing a different entry point to the
TBIOS. The entrypoint is defined by the contents of a
static lo cation in the BIOS Compatibility Area
(COMPAS).
2 PTC-2134 DOS Software Guide
Other Software Components
Operating System
The operating system provides additional higher-level
services to the Application Layer and uses the BIOS
interface for performing hardware functions. By using
standardized BIOS interfaces, the PC architecture
supports standard operating syste ms. The PTC-2134
supports the MS-DOS 6.22 operating system.
Application
The application is the highest software layer and
provides c ontrolling software programs for the unit.
Other Software Components
Software Kernel
The softwarekernel is a simple program loader that is
used to reprogram the PTC-2134 Flash PROM
memory areas.
PenRight! Operating Environment
PenRight! is a graphical application development tool
used to create forms containing objects such as
buttons, l ist boxes, and writing fields for pen-based
computers. These objects are activated with a stylus
pen, which can be used to select options, highlight
items, enter strings of characters, or enter a signature
on a digitized screen.
PenRight! applications are DOS progra ms that are
driven by events. Each depression or release of the
stylus on the digitized screen triggers a particular
type of programmed action.

Chapter 3 Configuring TN-3270/5250
Power Management
Power management is a necessityfor battery-operated
devices such as the PTC-2134. The unit is designed to
incorporate battery-saving p ower management
functionsdirectlyintothe unit hardwareand s oftware
architecture. The platform hardware incorporates
features t hat allow most internal elements to be
slowed down or deactivated. Together, the hardware
and software constantly monitor system activity and
implementpower management activity states that are
used for power management functions.
Software Development Kits
Symbol provides application development tools in the
form of Software Development Kits (SDKs) to help
developers design application programs for the SC400
product family. The SDK is a collection of run-time
libraries and TSRs that assist in the development of C
application programs on PC-compatible computers.
Once an application program is developed, it can be
copied to a PCMCIA card and in serted into th e
PTC-2134 to load or run the app lication.
Note: If converting applicationsfrom a PTC-1134, any
portion of the applicationsoftware that directly
manipulates the SLC (P TC-1134) hardware will
have to be re-written before it will work on the
PTC-2134. The internal architecture of the
PTC-2134 is not compatible with SLC. Any
software (BIOS, drivers, or applications) that
manipulates hardware must be written
specifically for the PTC-2134.

Radio Options
Batch
A batch unit does not have an antenna c able
integrated in the unit. It is still possible to install a
radio in the unit by way of the user accessible
PCMCIA slots. However, an antenna must be
installed on the radio. Either of the PCMCIA slots
may be used for a radio c ard.
LAN Radio Ready
The radio ready unit has an RSMA antenna cable
integratedintotheunit.Theendofthecableroutes
through the unit to the externally accessible PCMCIA
slot door. A radio can be installed into PCMCIA slot 0
(slot farthest from the unit’sdisplay).
LAN Radio Factory Installed
The radio factory installed unit utilizes the internally
installed PCM CIA slot (slot 2). An RSM antenna cable
integratedintotheunitroutestotheradiointhis
internalslot.Thisprovidestheunitwiththree
PCMCIA card slots and frees up both external
PCMCIA SLOTS for other uses . The radio is installed
in the internal slot (slot 2).
WAN Radio Factory Installed
When ordered with a WAN radio such as a DataTac or
Mobitex network radio, the radio mo dule is installed
internally in the unit. Because these radio types are
not PCMCIA form factor, they require additional
space in the unit. The unit therefore has a deeper
backshell than non W AN radio equipped units.
6 PTC-2134 DOS Software Guide
Memory
Memory
RAM
The PTC-2134 has RAM configurations of 4, 20, 36, or
64 MB on the CPU board. When the 16- and 32-MB
memory modules are added, the 4 MB is included. The
64-MBconfigurationactually contains68 MB of RAM,
but the SC400 is able to address only 64 MB and the
4 MB on the CPU board is disabled.
ROM
The PTC-2134 comes with 512 KB of ROM, w hic h
contains the BIOS for DOS.
Storage Options
ATA
The PTC -2134 supports ATA drives, both solid state
and rotating. ATA Type II cards can be applied to
either of the user accessible PCMCIA slots. Symbol
offers factory installed c ard s in a variety of sizes.
The 520-MB rotating ATA disks (any Type III) are
installed in PCMCIA slot 0.
SRAM
The PTC-2134 also supports SRAM (static RAM)
cards. Generally, these cards are used for special
purposes like reloadin g the ROM images (Genesis
procedure) or booting the unit, r ather than data
storage because the capacities are rather low (e.g.,
4 MB). However, these cards may also be used by the
application for data storage.
PTC-2134 DOS Software Guide 7
Chapter 3 Configuring TN-3270/5250
Compact Flash
The PTC-2134 has an internal Compact Flash ad ap ter
which is a standard 50 pin port that supports a
variety of Compact Flash module sizes.
PCMCIA Slots
The PTC-2134 has three PCMCIA slots, two that are
user-accessible and onethatis internal(whentheunit
is ordered with a factory installe d radio). T he two
external slotsare controlled by an Intel PCMCIA
controller. The internal slot is controlled by a Vadem
PCMCIA controller and is register-compatible with
the Intel 82365SL.
External Slots
Slot 0
This is the card slot farthest away from th e display.
Slot 1
This is the card slot closest to the display.
Internal Slot
Slot 2
This slot is located inside the unit and is only usab le
when the unit is ordered with a factory installed LAN
radio. O ther unit configurations will n ot be e quipped
with the PCMCIA card slot case to use this slot.
8 PTC-2134 DOS Software Guide
Display Types
Display Types
The PTC-2134 has a 640 x 480 VGA monochrome
liquid crystal display (LCD) screen, w hich can show
up to 64 shades of gray. The display also has a
resistive touch panel digitizer. The digitizer enables
the unit to recognize data entered w ith a passive
stylus. It also has a palm reject feature, which
prevents accidental activation of the unit by casual
hand or finger contact.
The display can be of either Transmissive or
Transflective type.
Transmissive Displays
Transmissive displays generally produce brighter
images than transflective displays but consume more
battery power.A transmissive display does not reflect
ambient light and is intended for indoor use on ly. It
requires the backlight to be on at all times.
Transflective Displays
Transflective displays use reflected ambient light to
produce viewable display images. It is ide al for use in
outdoor applications. For indoor use, the unit’s
backlight must be used to optimize the display
visibility. The backlight is defaulted to the ON setting
and can be turned off to conserve power.
IrDA
The PTC-2134 supports infrared communications via
anIrDAcompliantportatthebaseendoftheunit.

Chapter 3 Configuring TN-3270/5250
Ethernet
The PTC-2134 has an internal Ethernet interface and
is implemented by a CS8920 Crystal ISA Ethernet
controller. When the unit is docked into a cradle,
Ethernet signals pass through the contacts on the
cradle and unit, and then pass through the cra dl e’s
RJ-45 jack.
Refer to the section titled “
Management” on page 52 of this Guide for more
details.
Ethernet Power
DCD Devices
The PTC-2124 supports Symbol’s Data Collection
Device (DCD) architecture. This architecture allows
applications to obtain data from a variety of data
input devices without requiring that device-specific
code be written. Devices with DCD-compliant drivers
are sometimes referred to as DCD Devices.
Scanners
The PTC-2134 supports contact and non-contact
barcode sc anners. The appropriate module attaches to
the front underside of the unit. For non-contact
scanners, there are four activation buttons; two on the
top along the sides of the display, and two in the
scanning module itse lf, und erneath the unit. The
buttons o n the scan module are more access ible than
the buttons on the top of the unit and may be the
preferred activation buttons.

physical devices present in the system. This section
provides information on the following:
• The behavior of the BIOSat boot-up,
• Changing BIOS settings,

POST
In PC-base d systems, afte r a boot, the BIOS is
responsible for testing and initializing all hardware
components and boot-loading the operating system
into memory. This process is known as the Power-On
Self Test, or POST.
What Happens During POST
During the POST process, messages must be
generated for the system. The POST, initializations,
and messages are customized for the PTC-2134.
Once the POST operations are complete, the BIOS
loads the operating system. Once a bootable disk is
found, the boot loader is loaded into memory and
executed. If no bootable disk i s found, the system
displays a message: “No Boot Device Available.”
