Service Information
If you have a problem with your equipment, contact the “Symbol Global Interactive Center,” for your region. Go
to http://www.symbol.com/customersupport. If you purchased your Symbol product from a Symbol Business
Partner, contact that Business Partner for service.
Before contacting, have the model number and serial number at hand. If your problem cannot be solved by the
Symbol Global Interactive Center, you may need to return your equipment for servicing and you will be given
specific directions.
Symbol Technologies is not responsible for any damages incurred during shipment if the approved shipping
container is not used. Shipping the units improperly can possibly void the warranty. If the original shipping
container was not kept, contact Symbol to have another sent to you.

Returning the Vehicle Computer for Service
NOTE

Symbol has taken great care to ensure environmental conditions such as humidity will not affect the
stability of the vehicle computer. This is accomplished my means of desiccant bags which can be inserted
by the user upon receipt of the vehicle computer. In the event, the vehicle computer needs to be shipped
by air carrier to Symbol for repair or maintenance, it is essential that the user remove the desiccant door
cover before the vehicle computer is packaged for shipment. The reason for this step is to avoid
compromising the vehicle computer as a result of pressurization during air transit. The user must simply
remove the screws associated with the desiccant door on the back of the unit. Discard the used desiccant
bags. Upon receipt of the repaired vehicle computer, the user should insert new desiccant bags (if used)
and reseal the doors using new screws.

Routing Electrical Cables
•

Establish a neat route for the cable, staying clear of moving parts or hot surfaces.

•

Fix the cable to existing cable runs inside the vehicle using cable ties, but make sure they are away from
any moving or hot surfaces.

•

When the cabling must go through a panel, use a suitable gland.

•

When fixing the conduit or cable on the outside of a vehicle, use P-Clips. Either drill and tap the hole or
use a nut and bolt to secure the clip.

•

Ensure the cable does not have tight bends. The minimum recommended radius is 63.5 mm (2.5 in.).

•

On electric vehicles, take the power from as close to the battery as possible, but not directly from the
battery terminals, and not before any main fuse.

•

On gasoline, diesel or propane vehicles, take the power from as close to the battery terminals as
possible, and avoid using existing wiring.

•

All fuses must be as close as possible to the power source.

•

If you are unsure of the correct power source, contact the vehicle manufacturer for more information.

Installation

2-9

12-24 Volt Gasoline, Diesel, or Propane Forklifts
NOTE

The vehicle computer contains an Ignition Sense feature that detects when the ignition switch is turned
off and shuts the vehicle computer down after a preprogrammed timeout. This feature allows the operator
to use the vehicle computer for a predetermined time period after the ignition switch is turned off, then
shuts the vehicle computer down automatically to prevent over-discharge of the forklift battery. The
timeout period is adjustable by the user (see Ignition Sensing on page 3-17 for setting the timeout value).
The normal current draw of a suspended vehicle computer is approximately 500mA. When the vehicle
computer shuts down using the Ignition Sense feature, current draw is reduced to approximately 5 mA.
This feature provides the automatic shutoff functionality of an external relay, without requiring an actual
relay and has the added benefit of allowing the user to work for a preset time period before shutting
down.

•

All power wiring must use the supplied power cable.

•

Fuses:

• two 3AG, 20A, 250V, SLO BLO fuses
• one 3AG, 1A, 250V, SLO BLO fuse.
•

Keep the path between the battery and the vehicle computer as short as possible, and away from any
part of the ignition high tension system.

Installing the Vehicle In-Motion Detector
The optional Vehicle In-Motion Detector cable blanks the screen and disables use of the vehicle computer
when the vehicle is in motion. The customer must install a switch that is engaged when the vehicle accelerator
pedal is not depressed. When the pedal is not depressed, the switch is activated (closed) and sends a signal to
the vehicle computer indicating that the pedal is not depressed. When the accelerator pedal is depressed the
switch disengages and the signal removed. The screen blanks and the touch screen and keyboard are
disabled.
Whenever the vehicle is in motion (accelerator pedal is depressed) and the Terminal Locking feature is
enabled, the vehicle computer display blanks. When the accelerator pedal is not depressed, the vehicle
computer does not unlock immediately. Instead, the Complete Lockup Timeout timer initiates during which the
vehicle computer continues to remain locked. This ensures that the vehicle computer doesn’t unlock and lock
during any momentary disengagement of the accelerator pedal. While the Complete Lockup Timeout timer is
running, the touch screen, backlight and keyboard are disabled. After this timer expires, the Screen Blank
Timeout timer initiates. While this timer is running, the touch screen is enabled but the backlight and keyboard
are still disabled. If during this time the user touches the screen, the backlight comes on and the vehicle
computer unlocks fully. Otherwise after this timer expires, the backlight comes on and the vehicle computer
unlocks fully. If, while any of these timers are running, the vehicle pedal is pressed, the vehicle computer locks
again.
If the cable is cut or removed, the vehicle computer responds as if the pedal is depressed.

Switches
There are two types of switches that can be used; a solid state switch and a mechanical switch. Typically solid
state switches have a much longer life cycle than mechanical switches. Solid state switches require power
while mechanical switches do not.

Installation 2 - 29

The switch must be rated at 5V, 10 mA and it should have a operating temperature, sealing and life cycle
applicable for the environment that it is used in.
The mechanical switch must be a Normally Open type of switch.
The supply voltage for the solid state switch is 5 VDC (500 mA max.). When the switch is depressed the OUT
pin is pulled low.
The switch must be mounted permanently and must be positioned in such a way so that the switch is
depressed when the accelerator pedal is not pressed (vehicle at rest). When the accelerator pedal is pressed,
the switch should open and stay open until the pedal is released completely.

Cable Installation
One end of the cable connects to a customer provided switch and the other end connects to the COM1 or
COM2 port on the vehicle computer.
To install the Vehicle In-Motion Detector cable:
Follow these recommendations when installing the cable:

•

Establish a neat route for the cable, staying clear of moving parts or hot surfaces.

•

Place the cable in a rigid sleeve or conduit to protect the cable.

•

When the cabling must go through a panel, use a suitable gland.

•

When fixing the conduit or cable on the outside of a vehicle, use P-Clips. Either drill and tap the hole or
use a nut and bolt to secure the clip.

•

Ensure the cable does not have tight bends. The minimum recommended radius is 2.5".

•

Solder all wire connections.
Wire the cable and switch as shown in Figure 2-38.

> Settings > Control Panel >

To save battery power, set the vehicle computer to turn off after a specified number of minutes.

Ignition Sensing
The vehicle computer contains an Ignition Sense feature that detects when the ignition switch is turned off and shuts the
vehicle computer down after a preprogrammed timeout. This feature allows the operator to use the vehicle computer for a
predetermined time period after the ignition switch is turned off, then shuts the vehicle computer down automatically to
prevent over-discharge of the forklift battery. The timeout period is adjustable by the user. The normal current draw of a
suspended vehicle computer is approximately 500mA. When the vehicle computer shuts down using the Ignition Sense
feature, current draw is reduced to approximately 5 mA. This feature provides the automatic shutoff functionality of an
external relay, without requiring an actual relay and has the added benefit of allowing the user to work for a preset time
period before shutting down.

The power cable must be connected to the ignition switch. See Connecting the Power Cable on page 2-10 for
information on connecting the power cable to enable the Ignition Sense feature.

When the device is only used in a single country, set every profile country to Allow Any
Country. In the Options > Regulatory dialog box (see Figure 4-44 on page 4-34), select the
specific country the device is used in, and deselect the Enable 802.11d option. This is the
most common and efficient configuration, eliminating the initialization overhead
associated with acquiring a country via 802.11d.
Multiple Country Use:
When the device is used in more than one country, select the Enable 802.11d option in the
Options > Regulatory dialog box (see Figure 4-44 on page 4-34). This eliminates the need
for reprogramming the country (in Options > Regulatory) each time you enter a new
country. However, this only works if the infrastructure (i.e., APs) supports 802.11d (some
infrastructures do not support 802.11d, including some Cisco APs). When the Enable
802.11d option is selected, the Options > Regulatory > Country setting is not used. For a
single profile that can be used in multiple countries, with infrastructure that supports
802.11d (including Symbol infrastructure), set the Profile Country to Allow Any Country.
Under Options > Regulatory, select Enable 802.11d. The Options > Regulatory > Country
setting is not used.

Description

For a single profile that can be used in multiple countries, but with infrastructure that does
not support 802.11d, set the profile country to Allow Any Country, and de-select (uncheck)
Enable 802.11d. In this case, the Options > Regulatory > Country setting must always be
set to the country the device is currently in. This configuration option is the most efficient
and may be chosen for use with any infrastructure. However, the Options > Regulatory >
Country setting must be manually changed when a new country is entered.
Note that using a single profile in multiple countries implies that there is a common ESSID
to connect to in each country. This is less likely than having unique ESSIDs in each
country, this requires unique profiles for each country.
For additional efficiency when using multiple profiles that can be used in multiple
countries, the country setting for each profile can be set to a specific country. If the current
country (found via 802.11d or set by Options > Regulatory > Country when 802.11d is
disabled) does not match the country set in a given profile, then that profile is disabled.
This can make profile roaming occur faster. For example, if two profiles are created and
configured for Japan, and two more profiles are created and configured for USA, then
when in Japan only the first two profiles are active, and when in USA only the last two are
active. If they had all been configured for Allow Any Country, then all four would always
be active, making profile roaming less efficient.

MS CHAP v2

Microsoft Challenge Handshake Authentication Protocol version 2 (MS CHAP v2) is a
password-based, challenge-response, mutual authentication protocol that uses the
industry-standard Message Digest 4 (MD4) and Data Encryption Standard (DES)
algorithms to encrypt responses. The authenticating server challenges the access client
and the access client challenges the authenticating server. If either challenge is not
correctly answered, the connection is rejected. MS CHAP v2 was originally designed by
Microsoft as a PPP authentication protocol to provide better protection for dial-up and
virtual private network (VPN) connections. With Windows XP SP1, Windows XP SP2,
Windows Server 2003, and Windows 2000 SP4, MS CHAP v2 is also an EAP type.

TLS

EAP TLS is used during phase 2 of the authentication process. This method uses a user
certificate to authenticate.

Table 4-8 lists the TTLS tunneled authentication options.
Table 4-8 TTLS Tunneled Authentication Options

Authentication

Description

CHAP

Challenge Handshake Authentication Protocol (CHAP) is one of the two main
authentication protocols used to verify the user name and password for PPP Internet
connections. CHAP is more secure than PAP because it performs a three way
handshake during the initial link establishment between the home and remote
machines. It can also repeat the authentication anytime after the link is established.

MS CHAP

Microsoft Challenge Handshake Authentication Protocol (MS CHAP) is an
implementation of the CHAP protocol that Microsoft created to authenticate remote
Windows workstations. MS CHAP is identical to CHAP, except that MS CHAP is
based on the encryption and hashing algorithms used by Windows networks, and the
MS CHAP response to a challenge is in a format optimized for compatibility with
Windows operating systems.

MS CHAP v2 is a password based, challenge response, mutual authentication
protocol that uses the industry standard Message Digest 4 (MD4) and Data
Encryption Standard (DES) algorithms to encrypt responses. The authenticating
server challenges the access client and the access client challenges the

Windows 2000 SP4, MS CHAP v2 is also an EAP type.

PAP

Password Authentication Protocol (PAP) has two variations: PAP and CHAP PAP. It
verifies a user name and password for PPP Internet connections, but it is not as
secure as CHAP, since it works only to establish the initial link. PAP is also more
vulnerable to attack because it sends authentication packets throughout the network.
Nevertheless, PAP is more commonly used than CHAP to log in to a remote host like
an Internet service provider.

MD5

Message Digest-5 (MD5) is an authentication algorithm developed by RSA. MD5
generates a 128-bit message digest using a 128-bit key, IPSec truncates the
message digest to 96 bits.

Credential Cache Options
If you selected any of the password-based authentication types, you can select different credential caching
options. These options specify when the network credential prompts appear: at connection, on each resume,
or at a specified time.
Entering the credentials directly into the profile permanently caches the credentials. In this case, the vehicle
computer does not require user login. If a profile does not contain credentials entered through the configuration
editor, you must log in to the vehicle computer before connecting.
Caching options only apply on credentials entered through the login dialog box.

IP Address

The Internet is a collection of networks with users that communicate with each other. Each
communication carries the address of the source and destination networks and the
particular machine within the network associated with the user or host computer at each
end. This address is called the IP address (Internet Protocol address). Each node on the
IP network must be assigned a unique IP address that is made up of a network identifier
and a host identifier. Enter the IP address as a dotted-decimal notation with the decimal
value of each octet separated by a period, for example, 192.168.7.27.

Subnet Mask

Most TCP/IP networks use subnets to manage routed IP addresses. Dividing an
organization's network into subnets allows it to connect to the Internet with a single shared
network address, for example, 255.255.255.0.

IP
Address

Displays the vehicle computer’s IP address. The Internet is a collection of networks with users
that communicate with each other. Each communication carries the address of the source and
destination networks and the particular machine within the network associated with the user or
host computer at each end. This address is called the IP address. Each node on the IP network
must be assigned a unique IP address that is made up of a network identifier and a host
identifier. The IP address as a dotted-decimal notation with the decimal value of each octet
separated by a period, for example, 192.168.7.27.

Subnet

Displays the subnet address. Most TCP/IP networks use subnets to manage routed IP
addresses. Dividing an organization's network into subnets allows it to connect to the Internet
with a single shared network address, for example, 255.255.255.0.

Gateway

Displays the gateway address. A gateway forwards IP packets to and from a remote destination.

DCHP
Server

The Domain Name System (DNS) is a distributed Internet directory service. DNS translates
domain names and IP addresses, and controls Internet e-mail delivery. Most Internet services

Log On/Off Application
When the user launches the Log On/Off application, the vehicle computer may be in two states; the user may
be logged onto the vehicle computer by already entering credentials through the login box, or there are no user
logged on. Each of these states have a separate set of use cases and a different look to the dialog box.

User Already Logged In
If already logged into the vehicle computer, the user can launch the login dialog box for the following reasons:
•

Connect to and re-enable a cancelled profile. To do this:

- Launch the password dialog.
- Select the cancelled profile from the profile list.
- Login to the profile.
NOTE

Re-enable cancelled profiles using the Profile Editor Wizard and choosing to connect to the cancelled
profile. Cancelled profiles are also re-enabled when a new user logs on.

•

Log off the vehicle computer to prevent another user from accessing the current users network
privileges.

•

Switch vehicle computer users to quickly logoff the vehicle computer and allow another user to log into
the vehicle computer.

No User Logged In
If no user is logged into the vehicle computer, launch the login dialog box and log in to access user profiles.
The Login dialog box varies if it is:
•

Launched by Wireless Application, because the service is connecting to a new profile that needs
credentials.

•

Launched by Wireless Application, because the service is trying to verify the credentials due to credential
caching rules.

•

Launched by a user, when a user is logged in.

•

Launched by a user, when no user is logged in.

Device Username Field
The device username is a high level username used to link different network credentials to the same person as
explained above. The Device Username field is only writable when there is no user logged on. Otherwise it is
static text. The Device Username has a maximum length defined in the WCSAPI.

TLS, PEAP, LEAP, and EAP-TTLS.

Profile Status Icon

The profile status icon (next to the profile name) shows one of the following
states:
The selected profile is cancelled.
The selected profile is enabled but is not the current profile.
The profile is the current profile (always the case for when the Wireless
Application is launched).

Network Username and
Password Fields

The Network Username and Network Password fields are used as credentials
for the profile selected in the Wireless Profile field. Currently these fields are
limited to 159 characters.

Mask Password
Checkbox

The Mask Password checkbox determines whether the password field is masked
(i.e., displays only the '*' character) or unmasked (i.e., displays the entered text).
Check the box to unmask the password. Uncheck the box to mask the password
(the default).

Status Field

The status field displays status that is important to the login dialog. If the user
opens the dialog and needs to prompt for credentials for a particular profile at
this time, it can use the status field to let the user know that the network is held
up by the password dialog being open.

Tapping OK sends the credentials though Wireless Application API. If there are no credentials entered, a dialog
box displays informing the user which field was not entered.
The Log Off button only displays when a user is already logged on. When the Log Off button is tapped, the user
is prompted with three options: Log Off, Switch Users, and Cancel. Switching users logs off the current user
and re-initialize the login dialog box to be displayed for when there is no user logged on. Logging off logs off
the current user and close the login dialog box. Tapping Cancel closes the Log Off dialog box and the Login
dialog box displays.
When the user is logged off, the vehicle computer only roams to profiles that do not require credentials or to
profiles that were created with the credentials entered into the profile
The Cancel button closes the dialog without logging into the network. If the login dialog was launched by the
Wireless Application and not by the user, tapping Cancel first causes a message box to display a warning that
the cancel disables the current profile. If the user still chooses to cancel the login at this point, the profile is
cancelled.
Once a profile is cancelled, the profile is suppressed until a user actively re-enables it or a new user logs onto
the vehicle computer.

Using the Bluetooth

Chapter 5 Using the Bluetooth

Introduction
Bluetooth-equipped devices can communicate wirelessly, using frequency-hopping spread spectrum (FHSS)
RF to transmit and receive data in the 2.4 GHz Industry Scientific and Medical (ISM) band (802.15.1).
Bluetooth wireless technology is specifically designed for short-range (30 feet/10 meters) communications and
low power consumption.
Vehicle computers with Bluetooth capabilities can exchange information (e.g., files and tasks) with other
Bluetooth enabled devices such as scanners and printers.
Symbol vehicle computers with Bluetooth technology use the StoneStreet One Bluetooth stack. To program
Bluetooth within the vehicle computer refer to the StoneStreet One SDK.

Adaptive Frequency Hopping
Adaptive Frequency Hopping (AFH) is a method of avoiding fixed frequency interferers. AFH can be used with
Bluetooth voice. All devices in the piconet (Bluetooth network) must be AFH-capable in order for AFH to work.
There is no AFH when connecting and discovering devices. Avoid making Bluetooth connections and
discoveries during critical 802.11b communications. AFH for Bluetooth can be broken-down into four main
sections:
•

Channel Classification - A method of detecting an interference on a channel-by-channel basis, or
pre-defined channel mask.

•

Link Management - Coordinates and distributes the AFH information to the rest of the Bluetooth network.

•

Hop Sequence Modification - Avoids the interference by selectively reducing the number of hopping
channels.

•

Channel Maintenance - A method for periodically re-evaluating the channels.

When AFH is enabled, the Bluetooth radio “hops-around” (instead of through) the 802.11b high-rate channels.
AFH coexistence allows Symbol vehicle computers to operate in any infrastructure. AFH is always enabled in
the VC5090.
The Bluetooth radio in this vehicle computer operates as a Class 2 device power class. The maximum output
power is 2.5mW and the expected range is up to 32.8 feet (10 meters). A definitive definition of ranges based
on power class is difficult to obtain due to power and device differences, and whether one measures open
space or closed office space.

5-2

VC5090 Vehicle Computer Product Reference Guide

Security
The current Bluetooth specification defines security at the link level. Application-level security is not specified.
This allows application developers to define security mechanisms tailored to their specific need. Link-level
security is really between devices not users, while application-level security can be implemented on a per-user
basis. The Bluetooth specification defines security algorithms and procedures needed to authenticate devices,
and if needed, encrypt the data flowing on the link between the devices. Device authentication is a mandatory
feature of Bluetooth while link encryption is optional.
Pairing of Bluetooth devices is accomplished by creating an initialization key that is used to authenticate the
devices and create a link key for them. Entering a common PIN number in the devices being paired generates
the initialization key. The PIN number is never sent over the air. By default, the Bluetooth stack responds with
no key when a key is requested (it is up to user to respond to the key request event). Authentication of
Bluetooth devices is based-upon a challenge-response transaction. Bluetooth allows for a PIN number or
passkey that is used to create other 128-bit keys used for security and encryption. The encryption key is
derived from the link key used to authenticate the pairing devices. Also worthy of note is the limited range and
fast frequency hopping of the Bluetooth radios that makes long-distance eavesdropping difficult.
It is recommended:
•

Perform pairing in a secure environment

•

Keep PIN codes private and don't store the PIN codes in the vehicle computer

•

Implement application-level security.

Turning the Bluetooth Radio Mode On and Off
Turn off the Bluetooth radio to save power or if entering an area with radio restrictions (e.g., an airplane). When
the radio is off, the vehicle computer can not be seen or connected to by other Bluetooth devices. Turn on the
Bluetooth radio to exchange information with other Bluetooth devices (within range). Communicate only with
Bluetooth radios in close proximity.
NOTE

To achieve the best battery life in vehicle computers with multiple radios, turn off the radios that are not
being used.

Cold Boot
When a cold boot is performed on the vehicle computer, Bluetooth turns off. It is normal to see the Bluetooth
icon appear and disappear, as well as a wait cursor, when initialization proceeds in all modes.

Warm Boot
When a warm boot is performed on the vehicle computer, Bluetooth returns to the disabled state (off).

Suspend
When the vehicle computer suspends, Bluetooth turns off.
NOTE

When the vehicle computer is placed in suspend mode, the Bluetooth radio mode powers off and the
piconet (Bluetooth connection) is dropped. When the vehicle computer resumes, it could take up to 10
seconds for the Bluetooth radio driver to re-initialize the radio.

Resume
When the vehicle computer resumes, Bluetooth turns on if it was on prior to suspend. Note that any Bluetooth
connection that was dropped during a suspend needs to be reconnected after a resume.

Modes
The BTExplorer application has two mode for managing Bluetooth connections: Wizard Mode and Explorer
Mode. The Wizard Mode is for novice Bluetooth users and the Explorer Mode is for experienced Bluetooth
users.

Wizard Mode
Wizard Mode provides a simple step by step process for discovering and connecting to Bluetooth devices. The
wizard takes you through the entire process.

Chapter 6 ActiveSync

Introduction
To communicate with various host devices, install Microsoft ActiveSync (version 4.1 or higher) on the host
computer. Use ActiveSync to synchronize information on the vehicle computer with information on the host
computer. Changes made on the vehicle computer or host computer appear in both places after
synchronization.
ActiveSync software:
•

Allows working with vehicle computer-compatible host applications on the host computer. ActiveSync
replicates data from the vehicle computer so the host application can view, enter, and modify data on the
vehicle computer.

•

Synchronizes files between the vehicle computer and host computer, converting the files to the correct
format.

•

Backs up the data stored on the vehicle computer. Synchronization is a one-step procedure that ensures
the data is always safe and up-to-date.

•

Copies (rather than synchronizes) files between the vehicle computer and host computer.

•

Controls when synchronization occurs by selecting a synchronization mode, e.g., set to synchronize
continually while the vehicle computer is connected to the host computer, or set to only synchronize on
command.

•

Selects the types of information to synchronize and control how much data is synchronized.

Application Development and Deployment

Chapter 7
Chapter 7 Application Development and Deployment

Introduction
This chapter lists the tools required for developing applications, describes how to package applications and
provides procedures for deploying applications onto the VC5090.

Software Installation on Development PC (Application Development)
To develop applications to run on the vehicle computer, use one or more of the following:
•

Symbol Mobility Developer Kit (SMDK) for C

•

Symbol Mobility Developer Kit (SMDK) for Java

•

Symbol Mobility Developer Kit (SMDK) for .NET

The SMDK for C is a development tool used to create native C and C++ applications for all Symbol vehicle
computers. It includes documentation, header files (.H), and library files (.LIB) for native code application
development that targets Symbol value-add APIs.
The Windows CE Platform SDK for the VC5090 is used in conjunction with the SMDK for C to create Windows
CE applications for the VC5090 vehicle computer. The Platform SDK installs a new Windows CE device type
and its associated libraries onto the development PC. This new device is added to the Active WCE
Configuration field of Microsoft eMbedded Visual C++ 4.0. Visual Studio 2005 can also be used to develop
applications for the VC5090.
The Device Configuration Package (DCP) is required to create and download hex images that represent flash
partitions to the vehicle computer. The DCP includes the flash partitions, Terminal Configuration Manager
(TCM) and the associated TCM scripts.

Application folder: files stored in this folder are retained after a cold boot.

SD Card
The SD card can be used to download/upload files to and from the vehicle computer. See Installing a Secure
Digital Card on page 2-25 for instructions for installing an SD card. To view the contents of the SD card, open
Windows Explorer and select Storage Card. You can copy files from the SD card to the vehicle computer or
double-tap the executable file to launch the application.

IPL
Use IPL to download files onto the vehicle computer, to download customized flash file system partitions to the
vehicle computer and load hex files to the flash memory of the vehicle computer.
There are two types of updates supported by the vehicle computer: partitions and files. The file system used by
the vehicle computer is the same as the file system used on a desktop computer. A file is a unit of data that can
be accessed using a file name and a location in the file system. When a file is replaced, only the contents of the
previous file are erased. The operating system must be running for a file to be updated, so the IPL cannot
perform individual file updates as it is a stand-alone program that does not require the operating system to be
running.
A typical partition is a group of files, combined into a single “partition” that represents a specific area of storage.
Examples of partitions are the flash file systems such as Platform or Application. (Using the desktop computer

Application Development and Deployment

7-5

comparison, these partitions are roughly equivalent to a C: or D: hard disk drive.) In addition to the “hard disk”
partitions, some partitions are used for single items such as the operating system, monitor, or splash screen.
(Again using a desktop computer comparison, these partitions are roughly the equivalent of the BIOS or
special hidden system files.) When a partition is updated, all data that was previously in its storage region is
erased - i.e. it is not a merge but rather a replacement operation. Typically, the operating system is not running
when partitions are update, so IPL can perform partition updates.
Partition images for selected partitions can be created by TCM. All partition images suitable for use by IPL are
in hex file format for transfer by TCM from the development computer to the vehicle computer.
Upgrade requirements:
•

The hex files to be downloaded (on development computer)

•

A connection from the host computer and the vehicle computer (either serial or wireless)

•

TCM (on development computer) to download the files.

Once these requirements are satisfied, the vehicle computer can be upgraded by invoking IPL and navigating
the menus. See Sending the Hex Image on page 7-11 for procedures on downloading a hex file to the vehicle
computer.

7-6

VC5090 Vehicle Computer Product Reference Guide

Creating and Loading Hex Images
Terminal Configuration Manager (TCM) is an application used to customize flash file system partitions for the
vehicle computer. The most common use is to create an application partition hex file that contains the
customer's application. TCM can also be used to load hex files to the flash memory of the vehicle computer.
The program resident on the vehicle computer that receives the hex file and burns it to the flash memory is
called Initial Program Loader (IPL).
The customization of partitions is controlled by TCM scripts. The scripts contain all of the necessary
information for building an image. The script is a list of copy commands specifying the files to copy from the
development computer to the partition.
TCM works with a pair of directory windows, one displaying the script and the other displaying the source files
resident on the development computer. Using standard windows drag and drop operations, files can be added
and deleted from the script window.
The DCP for VC5090w includes scripts used by Symbol Technologies to build the standard factory installed
Platform and Application partitions provided on the vehicle computer. The standard Platform partition contains
drivers while the Application partition contains demo applications and optional components. The standard TCM
scripts can be found in the following folder: C:\Program Files\Symbol Device Configuration
Packages\VC5090x\v1.0\TCM Scripts.
NOTE

Before creating a script to build a hex image, identify the files required (system files, drivers, applications,
etc.) and locate the files’ source directories to make the script building process easier.

The required processes for building a hex image in TCM include:
•

Starting TCM

•

Defining script properties

•

Creating the script for the hex image

•

Building the image

•

Sending the hex image

•

Creating a splash screen

•

Flash storage.

Starting Terminal Configuration Manager
Click the Windows start menu TCM icon (Symbol Device Configuration Packages, VC5090w v1.0) to start
TCM. The TCM window appears displaying two child windows: Script1 and File Explorer. The Script1 window

Creating the Script for the Hex Image
On start-up, TCM displays the TCM window with the Script1 window and File Explorer window pointing to the
following directory:
$ \Program Files\Symbol Device Configuration Packages\VC5090w\v0.1\TCMScripts\

The Script1 window directory pane displays two partitions: Platform and Application. Depending on the type of
flash chip, the number of partitions may change. Files can be added to each of the partitions. TCM functionality
includes:
•

Opening a new or existing script file

•

Copying components to the script window

•

Saving the script file.

Opening a New or Existing Script
A script file can be created from scratch or based on an existing script file. Click Create to create a new script or
click Open to open an existing script (for example, a script provided in the DCP for VC5090w). If an existing
script is opened and changes are made, saving the changes overwrites the original script. To use an original or
Symbol supplied standard script as a base and save the changes in a new script, use the Save As function to
save the script using a different file name.

Updating TCM 1.X Scripts
Script files that were created with older versions of TCM can be upgraded to TCM 2.0 scripts. Click Open to
open an existing script created with an older version of TCM. The Conversion window appears automatically.

7 - 10 VC5090 Vehicle Computer Product Reference Guide

Figure 7-6 Conversion Window - Upgrading to TCM 2.0

Copying Components to the Script
Script contents are managed using standard file operations such as New Folder, Delete and Rename. Items can
be added to the script by clicking files and folders in the File Explorer window and dragging them to the Script
window. The File Explorer window supports standard windows; multiple files may be selected by clicking while
holding the SHIFT or CTRL keys.

Saving the Script
Modifications to a script file can be saved using the Save or the Save As function. Saving changes to an existing
script writes over the original script. To use a Symbol-supplied standard script as a base and save the changes
in a new script, use the Save As function.

Building the Image
Once the script is created, the hex image defined by the script can be built.
As part of the build, TCM performs a check on the script which verifies that all files referenced in the script
exist. This check is important for previously created scripts to ensure that files referenced in the script are still
in the designated locations.
To build scripts:
1.

Click Build on the TCM toolbar. The Configure Build window appears.

Figure 7-7 Configure Build Window
2.

Select the items (partitions) to build using the check box(es) to the left of each named partition.

The Build Path defines where to store all built partitions.

Select (hex image) COMPRESSION to reduce the size and speed up the download.

Application Development and Deployment 7 - 11

Click OK and follow the on-screen instructions.

If one of the partitions being built is the ESSID, a prompt appears requesting the ESSID value. Deselect
the HR (High Rate) check box when building ESSID images for a device with an FH radio.

Figure 7-8 Build ESSID Partition Window
7.

If one of the partitions being built is the Splash Screen, a prompt appears requesting both the source
Bitmap file and the destination HEX file.

A check is performed and if there are no errors, the partition hex files are created.

If the build fails, the hex files are not be created and TCM displays an error message. Two of the most common
reasons for a build failure are:
•

Files defined in the script can not be found. This error can occur when the files referenced by the script
are no longer stored on the development computer or the folders where they are stored were renamed.

•

The total amount of flash memory space required by the script exceeds the image size. To correct this,
reduce the number of files in the partition or increase the size of the partition. See Defining Script
Properties on page 7-8 for more information about setting the image size appropriately.

Sending the Hex Image
Once the hex file is built, it can be downloaded to the vehicle computer.

Using TCM
To load the hex files on to the vehicle computer:
1.

For downloads using an RS232 serial connection, connect the rugged RS232 cable to the COM1 port on
the vehicle computer and the other end to the development computer.
or

Creating a Splash Screen
The source bitmap files used to create the default splash screens for the vehicle computer are supplied with
the DCP for VC5090c50. These files can be modified using any of the standard windows image editors,
allowing customization for particular customers.
To create a custom splash screen, perform the following steps:
1.

Open the Splashcolor.bmp file supplied with the DCP for VC5090c50 using an image editor.

Modify the bitmap file and save.

Create a splash partition using the steps shown in the Building the Image on page 7-10.

Splash Screen Format
If the default files are not used to create the new splash screens, be sure to preserve the image format. The
formats are as follows:
Screen Type

Color

Dimensions

490x296

Color Format

8 bits per pixel*

* 8 bits per pixel only applies to splash screen images. Once Windows CE is running, the color density is 16 bits
per pixel.
See Sending the Hex Image on page 7-11 for information about loading the splash screen using TCM and IPL.

Flash Storage
In addition to the RAM-based storage standard on Windows CE vehicle computers, the vehicle computer is
also equipped with a non-volatile Flash-based storage area which can store data (partitions) that can not be
corrupted by a cold boot. This Flash area is divided into two categories: Flash File System (FFS) Partitions and
Non-FFS Partitions.

FFS Partitions
The vehicle computer includes two FFS partitions. These partitions appear to the vehicle computer as a hard
drive that the OS file system can write files to and read files from. Data is retained even if power is removed.
The two FFS partitions appear as two separate folders in the Windows CE file system and are as follows:

Application Development and Deployment 7 - 23

•

Platform: The Platform FFS partition contains Symbol-supplied programs and Dynamic Link Libraries
(DLLs). This FFS is configured to include DLLs that control system operation. Since these drivers are
required for basic vehicle computer operation, only experienced users should modify the content of this
partition.

•

Application: The Application FFS partition is used to store application programs needed to operate the
vehicle computer.

Working with FFS Partitions
Because the FFS partitions appear as folders under the Windows CE file system, they can be written to and
read like any other folder. For example, an application program can write data to a file located in the
Application folder just as it would to the Windows folder. However, the file in the Application folder is in
non-volatile storage and is not lost on a cold boot (e.g., when power is removed for a long period of time).
Standard tools such as ActiveSync can be used to copy files to and from the FFS partitions. They appear as
the “Application” and “Platform” folders to the ActiveSync explorer. This is useful when installing applications
on the vehicle computer. Applications stored in the Application folder are retained even when the vehicle
computer is cold booted.
There are two device drivers included in the Windows CE image to assist developers in configuring the vehicle
computer following a cold boot: RegMerge and CopyFiles.

RegMerge.dll
RegMerge.dll is a built-in driver that allows registry edits to be made to the Windows CE Registry.
Regmerge.dll runs very early in the boot process and looks for registry files (.reg files) in certain Flash File
System folders during a cold boot. It then merges the registry changes into the system registry located in RAM.
Since the registry is re-created on every cold boot from the default ROM image, the RegMerge driver is
necessary to make registry modifications persistent over cold boots.
RegMerge is configured to look in the root of two specific folders for .reg files in the following order:
\Platform
\Application
Regmerge continues to look for .reg files in these folders until all folders are checked. This allows folders later
in the list to override folders earlier in the list. This way, it is possible to override Registry changes made by the
Platforms partitions folders. Take care when using Regmerge to make Registry changes. The DCP for
VC5090w contains examples of .reg files.
NOTE

Regmerge only merges the .reg files on cold boots. The merge process is skipped during a warm boot.

Typically, do not make modifications to registry values for drivers loaded before RegMerge. However, these
values may require modification during software development. Since these early loading drivers read these
keys before RegMerge gets a chance to change them, the vehicle computer must be cold booted. The warm
boot does not re-initialize the registry and the early loading driver reads the new registry values.
Do not use Regmerge to modify built-in driver registry values, or merge the same Registry value to two files in
the same folder, as the results are undefined.

7 - 24 VC5090 Vehicle Computer Product Reference Guide

CopyFiles
Windows CE expects certain files to be in the Windows folder, residing in volatile storage. Windows CE
maintains the System Registry in volatile storage. CopyFiles copies files from one folder to another on a cold
boot. Files can be copied from a non-volatile partition (Application or Platform) to the Windows or other volatile
partition during a cold boot. During a cold boot CopyFiles looks for files with a .CPY extension in the root of the
Platform and Application FFS partitions (Platform first and then Application). These files are text files
containing the source and destination for the desired files to be copied separated by “>”. The following example
from the file application.cpy is contained on the demo application partition included in the DCP for VC5090w. It
can also be obtained from the Symbol web site at http://devzone.symbol.com/.
Files are copied to the Windows folder from the Flash File System using copy files (*.cpy) in the following
order:
\Platform
\Application
Example:
\Application\ScanSamp2.exe>\Windows\ScanSamp2.exe
This line directs CopyFiles to copy the ScanSamp2.exe application from the \Application folder to the
\Windows folder.

Non-FFS Partitions
Non-FFS Partitions include additional software and data pre-loaded on the vehicle computer that can be
upgraded. Unlike FFS Partitions, these partitions are not visible when the operating system is running. They
also contain system information. Non-FFS partitions include the following:
•

Windows CE: The complete Windows CE operating system is stored on Flash devices. If necessary, the
entire OS image may be downloaded to the vehicle computer using files provided by Symbol. The
current OS partition on the vehicle computer is included as part of the TCM installation package. Any
upgrades must be obtained from Symbol. This partition is mandatory for the vehicle computer.

•

Splash Screen: a bitmap smaller than 16 Kb (and limited to 8 bits per pixel) is displayed as the vehicle
computer cold boots. To download a customized screen to display, see Creating a Splash Screen on
page 7-22.
NOTE

8 bits per pixel only applies to splash screen images. Once Windows CE is running, the color density is 16
bits per pixel.

•

IPL: This program interfaces with the host computer and allows downloading via serial cable any or all of
the partitions listed above, as well as updated versions of IPL. Use caution downloading updated IPL
versions; incorrect downloading of an IPL causes permanent damage to the vehicle computer. IPL is
mandatory for the vehicle computer.

•

Partition Table: Identifies where each partition is loaded in the vehicle computer.

Downloading Partitions to the Vehicle Computer
TCM is used to specify a hex destination file for each partition and download each file to the vehicle computer.
This download requires a program loader stored on the vehicle computer. The vehicle computer comes with a
program loading utility, Initial Program Loader (IPL), stored in the vehicle computer's write-protected flash.

Application Development and Deployment 7 - 25

AirBEAM Smart
The AirBEAM Smart product allows specially designed software packages to be transferred between a host
server and Symbol wireless handheld devices. Before transfer, AirBEAM Smart checks and compares
package version, so that only updated packages are loaded.
AirBEAM Smart resides on radio-equipped client devices and allows them to request, download and install
software, as well as to upload files and status data. Both download and upload of files can be accomplished in
a single communications session. The ability to transfer software over a radio network can greatly reduce the
logistical efforts of client software management.
In an AirBEAM Smart system, a network-accessible host server acts as the storage point for the software
transfer. The AirBEAM Smart Client uses the industry standard FTP or TFTP file transfer protocols to check the
host system for updates and, if necessary, to transfer updated software.
NOTE

For more detailed information about AirBEAM Smart, refer to the AirBEAM® Smart Windows® CE Client
Product Reference Guide (p/n 72-63060-xx).

AirBEAM Package Builder
In a typical distributed AirBEAM system, software to be transferred is organized into packages. In general, an
AirBEAM package is simply a set of files that are assigned attributes both as an entire package and as
individual component files. The package is assigned a version number and the transfer occurs when an
updated version is available.
An AirBEAM package can optionally contain developer-specified logic to be used to install the package.
Installation logic is typically used to update client device flash images or radio firmware. Examples of common
AirBEAM packages would include packages for custom client application software, radio firmware and
AirBEAM Smart Client software.
Once these packages are built, they are installed on the host server for retrieval by the handheld device. The
AirBEAM Package Builder is a utility used to define, generate and install AirBEAM packages to a server. The
packages are then loaded from the server onto a client device equipped with an AirBEAM Smart Client
executable.
For detailed instructions on how to define, generate and install AirBEAM packages to the server, refer to the
AirBEAM Package Builder Product Reference Guide, p/n 72-55769-xx.

AirBEAM Smart Client
The AirBEAM Smart Client is installed on the handheld vehicle computer. It is configured with the server
access information, the names of the packages to be downloaded and other controlling parameters. When the
AirBEAM Smart Client is launched, the device connects to the specified FTP server and checks the packages
it is configured to look for. If the package version was updated, the client requests the transfer.

AirBEAM License
The AirBEAM Smart Client is a licensed software product. The AirBEAM Smart Client's version
synchronization functionality is enabled through a license key file that is stored on the client device. The
license key file can be built into AirBEAM Smart Client's image, or downloaded in a special AirBEAM package.
The AirBEAM license key file contains a unique key and a customer specific banner that is displayed when the
AirBEAM Smart Client version synchronization logic is invoked.

Auto-load

This drop-down list is used to specify how the AirBEAM Smart Client is to be invoked
automatically when the client device is rebooted. The selections are:
Disable: the AirBEAM Smart Client is not invoked automatically during the boot
sequence.
Interactive: the AirBEAM Smart Client is invoked automatically during the boot
sequence. The package synchronization process is started automatically. The
Synchronization Dialog box appears and the user is required to press the OK button
when the process is complete.
Non-interactive: the AirBEAM Smart Client is invoked automatically during the boot
sequence. The package synchronization process is started automatically. The
Synchronization Dialog box is displayed, but the user is not required to tap OK when the
process is complete. The Synchronization Dialog box terminates automatically.
Background: the AirBEAM Smart Client is invoked automatically during the boot
sequence. The package synchronization process is started automatically. Nothing is
displayed while the synchronization process is occurring.

RAM Management

This check box specifies whether the automatic RAM management is enabled during the
package synchronization process.
If enabled, RAM management logic is invoked when there is not enough free disk space
to download a package. The RAM management logic attempts to remove any
discardable AirBEAM packages resident on the client.

Suppress Separator

This check box specifies whether the automatic insertion of a file path separator
character should be suppressed when the client generated server package definition file
names.
When enabled, the parameter also disables the appending of .apd to the package. This
feature is useful for AS/400 systems, in which the file path separator character is a
period. When this feature is enabled, the server directory (Directory) and package name
(Package 1, Package 2, Package 3 and Package 4) are appended “as is” when building
the name for the server package definition file.
When this feature is disabled, a standard file path separator is used to separate the
server directory (Directory) and package name (Package 1, Package 2, Package 3 and
Package 4) when building the name for the server package definition file. In addition,
an .apd extension is appended automatically.

Synchronizing with the Server
When the synchronization process is initiated, the AirBEAM Smart Client attempts to open an FTP session
using the AirBEAM Smart Client configuration. Once connected, the client processes the specified packages.
Packages are loaded only if the server version of a given package is different from the version loaded on the
client. Once the upload process is complete, the AirBEAM Smart Client closes the FTP session with the server.
The AirBEAM Smart Client can launch an FTP session with the server either manually, when initiated by the
user, or automatically.

Manual Synchronization

AirBEAM Staging
The AirBEAM Smart staging support is intended to speed up and simplify the process of staging custom or
updated operating software onto mobile devices directly from manufacturing. The staging support is part of the
AirBEAM Smart CE Client that is integrated into the vehicle computer.
The AirBEAM Smart support works by defaulting the AirBEAM Client configuration to a known set of values
and launching the AirBEAM Smart package download logic. A staging environment, including an RF network,
FTP server and AirBEAM packages must be setup. Ideally a staging network and server should be setup to
match the default AirBEAM Staging client configuration.
The AirBEAM Smart staging utility is invoked from the Application directory (tap
> Windows).

Input/Output Ports. I/O ports are primarily dedicated to passing information into or out of the vehicle computer’s
memory. VC5090 vehicle computers include Serial and USB ports.
IP. Internet Protocol. The IP part of the TCP/IP communications protocol. IP implements the network layer (layer 3) of
the protocol, which contains a network address and is used to route a message to a different network or subnetwork.
IP accepts “packets” from the layer 4 transport protocol (TCP or UDP), adds its own header to it and delivers a
“datagram” to the layer 2 data link protocol. It may also break the packet into fragments to support the maximum
transmission unit (MTU) of the network.
IP Address. (Internet Protocol address) The address of a computer attached to an IP network. Every client and server
station must have a unique IP address. A 32-bit address used by a computer on a IP network. Client workstations
have either a permanent address or one that is dynamically assigned to them each session. IP addresses are written
as four sets of numbers separated by periods; for example, 204.171.64.2.
IPX/SPX. Internet Package Exchange/Sequential Packet Exchange. A communications protocol for Novell. IPX is
Novell’s Layer 3 protocol, similar to XNS and IP, and used in NetWare networks. SPX is Novell's version of the Xerox
SPP protocol.
IS-95. Interim Standard 95. The EIA/TIA standard that governs the operation of CDMA cellular service. Versions include
IS-95A and IS-95B. See CDMA.

L
LCD. See Liquid Crystal Display.

excited by precise electrical charges, causing them to reflect light outside according to their bias. They use little
electricity and react relatively quickly. They require external light to reflect their information to the user.
Light Emitting Diode. See LED.

M
MDN. Mobile Directory Number. The directory listing telephone number that is dialed (generally using POTS) to reach
a mobile unit. The MDN is usually associated with a MIN in a cellular telephone -- in the US and Canada, the MDN
and MIN are the same value for voice cellular users. International roaming considerations often result in the MDN
being different from the MIN.
MIN. Mobile Identification Number. The unique account number associated with a cellular device. It is broadcast by the
cellular device when accessing the cellular system.

N
NVM. Non-Volatile Memory.

O
ODI. See Open Data-Link Interface.
Open Data-Link Interface (ODI). Novell’s driver specification for an interface between network hardware and
higher-level protocols. It supports multiple protocols on a single NIC (Network Interface Controller). It is capable of
understanding and translating any network information or request sent by any other ODI-compatible protocol into
something a NetWare client can understand and process.
Open System Authentication. Open System authentication is a null authentication algorithm.

P
PAN . Personal area network. Using Bluetooth wireless technology, PANs enable devices to communicate wirelessly.
Generally, a wireless PAN consists of a dynamic group of less than 255 devices that communicate within about a
33-foot range. Only devices within this limited area typically participate in the network.
Parameter. A variable that can have different values assigned to it.
PING. (Packet Internet Groper) An Internet utility used to determine whether a particular IP address is online. It is used
to test and debug a network by sending out a packet and waiting for a response.

Glossary - 5

Print Contrast Signal (PCS). Measurement of the contrast (brightness difference) between the bars and spaces of a
symbol. A minimum PCS value is needed for a bar code symbol to be scannable. PCS = (RL - RD) / RL, where RL
is the reflectance factor of the background and RD the reflectance factor of the dark bars.
Programming Mode. The state in which a scanner is configured for parameter values. See Scanning Mode.

Q
QWERTY. A standard keyboard commonly used on North American and some European PC keyboards. “QWERTY”
refers to the arrangement of keys on the left side of the third row of keys.

R
RAM. Random Access Memory. Data in RAM can be accessed in random order, and quickly written and read.
Reflectance. Amount of light returned from an illuminated surface.
Resolution. The narrowest element dimension which is distinguished by a particular reading device or printed with a
particular device or method.
RF. Radio Frequency.
ROM. Read-Only Memory. Data stored in ROM cannot be changed or removed.
Router. A device that connects networks and supports the required protocols for packet filtering. Routers are typically
used to extend the range of cabling and to organize the topology of a network into subnets. See Subnet.
RS-232. An Electronic Industries Association (EIA) standard that defines the connector, connector pins, and signals
used to transfer data serially from one device to another.

S
Scanner. An electronic device used to scan bar code symbols and produce a digitized pattern that corresponds to the
bars and spaces of the symbol. Its three main components are: 1) Light source (laser or photoelectric cell) illuminates a bar code,; 2) Photodetector - registers the difference in reflected light (more light reflected from
spaces); 3) Signal conditioning circuit - transforms optical detector output into a digitized bar pattern.
SDK. Software Development Kit
Shared Key. Shared Key authentication is an algorithm where both the AP and the MU share an authentication key.
SID. System Identification code. An identifier issued by the FCC for each market. It is also broadcast by the cellular
carriers to allow cellular devices to distinguish between the home and roaming service.

SMDK. Symbol Mobility Developer’s Kit.
Soft Reset. See Warm Boot.
Subnet. A subset of nodes on a network that are serviced by the same router. See Router.
Subnet Mask. A 32-bit number used to separate the network and host sections of an IP address. A custom subnet mask
subdivides an IP network into smaller subsections. The mask is a binary pattern that is matched up with the IP
address to turn part of the host ID address field into a field for subnets. Default is often 255.255.255.0.
Substrate. A foundation material on which a substance or image is placed.
SVTP. Symbol Virtual Vehicle Computer Program.

T
TCP/IP. (Transmission Control Protocol/Internet Protocol) A communications protocol used to internetwork dissimilar
systems. This standard is the protocol of the Internet and has become the global standard for communications. TCP
provides transport functions, which ensures that the total amount of bytes sent is received correctly at the other end.
UDP is an alternate transport that does not guarantee delivery. It is widely used for real-time voice and video
transmissions where erroneous packets are not retransmitted. IP provides the routing mechanism. TCP/IP is a
routable protocol, which means that all messages contain not only the address of the destination station, but the
address of a destination network. This allows TCP/IP messages to be sent to multiple networks within an
organization or around the world, hence its use in the worldwide Internet. Every client and server in a TCP/IP
network requires an IP address, which is either permanently assigned or dynamically assigned at startup.
Telnet. A vehicle computer emulation protocol commonly used on the Internet and TCP/IP-based networks. It allows a
user at a vehicle computer or computer to log onto a remote device and run a program.
Terminal Computer Emulation. A “terminal computer emulation” emulates a character-based mainframe session on a
remote non-mainframe terminal computer, including all display features, commands and function keys. The VC5090
Series supports Terminal Computer Emulations in 3270, 5250 and VT220.
TFTP. (Trivial File Transfer Protocol) A version of the TCP/IP FTP (File Transfer Protocol) protocol that has no directory
or password capability. It is the protocol used for upgrading firmware, downloading software and remote booting of
diskless devices.
Tolerance. Allowable deviation from the nominal bar or space width.
Transmission Control Protocol/Internet Protocol. See TCP/IP.
Trivial File Transfer Protocol. See TFTP.

U
UDP. User Datagram Protocol. A protocol within the IP protocol suite that is used in place of TCP when a reliable
delivery is not required. For example, UDP is used for real-time audio and video traffic where lost packets are simply

Glossary - 7

ignored, because there is no time to retransmit. If UDP is used and a reliable delivery is required, packet sequence
checking and error notification must be written into the applications.

V
VC. Vehicle Computer.
Vehicle Computer. In this text, vehicle computer refers to the Symbol VC5090 vehicle computer. It can be set up to run
as a stand-alone device, or it can be set up to communicate with a network, using wireless radio technology.

W
