2. Architecture Overview
The Portable Shopping System utilizes Symbol Technologies’ proprietary WaveWorks three-
tiered architecture, which provides clear separation of the user interface, business logic and
database portions of the system. For the PSS, WaveWorks provides application messaging
functions and manages distributed objects on the Microsoft Windows NT platform.
2.1 Introduction to WaveWorks
WaveWorks is a light weight, high performance, three-tiered, application messaging and
distributed object management architecture which is designed to run on the Windows NT system
platform. As a horizontal system component, WaveWorks can serve as the backbone
architecture for a wide variety of multitiered client/server applications.
The WaveWorks system provides the following application services:
• Thin client radio terminal environment (reduces system administration costs)
• Radio Terminal display and client state management
• Client-to-Server and Client-to-Client messaging service
• Business Service object broker
• Configurable Business Servers
• Distributed business service objects
• Load-based object instancing
• Load balancing
• Service based instancing
• DBMS connection sharing
• Client specific object instancing
• Web-based system administration.
• Application user password validation and security service

2.1.1 WaveWorks Design Objectives
Three-tiered ArchitectureWaveWorks provides a platform for implementing applications that
maintain a clear separation between the user interface, business logic, and database layers.
Light WeightWaveWorks is designed to run on P200 systems or better.
AdaptableCOM object-based design allows easy addition of new business service objects to
support new applications. The encapsulation of data access inside business objects makes it easy
to change data sources in the future, without rewriting the entire application.
Business Object ReuseCOM object-based design allows easy reuse of existing business service
objects to support new applications.
ScaleableA distributed-object architecture makes it easy to add additional business service
capacity, based on changing business demands.
DistributedWaveWorks system components are designed so they can be deployed across LAN
or WAN networks. Network utilization can be optimized by placing the WaveWorks Business
Server components near or on the DBMS server, while running the Display Server / Message
Server components near or on the client connection point server.
High PerformanceMultithreaded business service execution, avoidance of persistent message
queues, event driven implementation (no polling), and automatic load balancing permit message
rates of up to 500 per second (on a single system configuration).
ReliableWaveWorks supports the ability to configure multiply redundant parallel Business
Server components. In addition to load sharing, the redundant servers will automatically hot-
swap / load-shift to the remaining servers if one or more server systems suffer a complete or
partial failure.
Platform IndependenceDependency on NT specific features are minimal and are internally
well isolated.
Minimum Dependency on Third-party ComponentsTo improve platform portability and reduce
licensing costs, WaveWorks depends on only generally available add-on components, such as: an
ODBC compliant DBMS, Winsock 1.1, an http server, and a third-generation (or better) Web
browser. A suitable version of all of these components is included with NT 4.0 server.

2.1.2 WaveWorks Components
The WaveWorks components are shown in the following diagram and described below.
Display ServerManages the user interface and screen flow for radio-based, thin client
applications. Maintains client data variables to record the state of the client application. Invokes
business services via WaveWorks messages.
Message ServerProvides light weight message routing and load balancing services between
the various WaveWorks system components. Supports Command / Response style
communication for the execution of business services, and unsolicited client-to-client messaging.
Business Server (Object Broker)Manages the creation, destruction, and invocation of COM-
based business service objects. Automatically creates and destroys object instances based on
system demand. Permits sharing of database connections by multiple clients. The WaveWorks
architecture supports multiple Business Servers, running on either local or remote systems.

WaveWorks MessagesThe WaveWorks messaging service uses a common message format
for all WaveWorks messages. This format contains a fixed header, followed by zero or more
application dependent data fields. TCP is used as the transport protocol for all WaveWorks
messages. This permits the business logic tier to reside on a remote system, if desired. The
messages form the "glue" that cements the client interface tier of the application to the business
logic tier. The messaging service can also be used to implement direct "client-to-client"
messaging.
Business Service ObjectsContain the vertical business application logic, implemented as
Microsoft COM automation server objects. The term "Service Object" is used to describe the
COM interface subset to which all WaveWorks-managed objects must adhere.
Transaction ModelWaveWorks uses a transaction Id scheme to provide namespace services
for purposes of automatically routing request messages to a capable Business Server for
execution.
Development Tools (Optional Component)An application interface development tool (Screen
Maker) supports rapid development of thin client radio applications. A radio terminal simulation
tool (Screen Runner) permits testing of Screen Maker applications without the need for an actual
radio network. A WaveWorks C++ foundation class library is also available, which includes
classes that support ODBC data access, WaveWorks messaging, INI file access, Date / Time
manipulation,and more.

2.2 PSS Software Overview
Built upon the WaveWorks core software, the PSS software consists of
• COM Objects
• NT Services
• Display Server Scripts
• Database
The COM Objects and NT Services perform the business logic. That is, they are responsible for
the data manipulation and system sequencing that makes the system a portable shopping system.
The methods contained in the COM Objects and the NT Services are invoked via WaveWorks
transactions. The COM Objects are dynamically created and deleted by the Business Server. The
NT Services are started at system startup and remain resident in the system.
The Display Server scripts provide the user interface mechanism for the hand held terminals and
entrance units. The scripts define the screen layout and provide the handling of user actions for
those devices. When necessary, the scripts invoke business methods via WaveWorks
transactions.
The database contains all of the persistent data of the system. The database is used to store all
information about the devices, shoppers, items, and system configuration as required.
2.3 Major Subsystems
2.3.1 Unit Management Subsystem
The Unit Management Subsystem (UMS) manages the Symbol hardware devices that comprise
the PSS system. Those devices include hand held terminals, cradles, entrance unit devices, ticket
printers, and power supplies. UMS ensures that the devices work in concert with one another to
provide a seamless integrated system.
2.3.2 Shopping Trip Subsystem
Once the shopper retrieves the proper hand held terminal from the dispenser, the Shopping Trip
application allows the shopper to add and delete items from their basket and view the “totals”
information for their current shopping trip. Shopping trips can be ended by returning the hand
held terminal to an empty dispenser slot or by scanning an “End of Trip” barcode. Each activity
during the shopping trip is logged and available for review from the Service Terminal.

2.3.3 Quick Order Subsystem
While shopping, a user may choose to place a quick order through the optional Quick Order
subsystem provided. The shopper identifies, through the quick order mechanism, the products
and the quantities/weights of those products they wish to order. The quick order can then be sent
to the appropriate department, where a web screen displays to store personnel the orders placed
by shoppers. After they have finished processing the order, store personnel can send a message
to the shopper that their order is ready to be picked up.
2.3.4 Queue Busting Subsystem
The Queue Busting subsystem allows the PSS System to be used in a slightly different manner
than normal, but also helps retailers and shoppers reduce the amount of checkout time. Any
hand held terminal which has been released can be used for queue busting. This is normally
done by store personnel to alleviate long checkout lines which may have formed.
Transactions in this mode are initiated by scanning a special (configurable) barcode. More than
one barcode can be configured for use in this manner. This barcode is expected to be on a plastic
token. Once the special barcode has been scanned, the items in the customer basket are scanned.
A PSS transaction is created in the same manner as a normal PSS transaction. After all items in
the basket have been scanned, the special barcode, which began this mode, is scanned again.
This transaction is sent to the POS System. The plastic token containing the barcode is then
handed to the customer with instructions to give it to the cashier at the checkout register. When
the customer reaches the register, they present the token and their loyalty card (if used) to the
cashier who then performs a standard non-audit self scan checkout. After the customer checks
out, the token can be re-used for other customers.
2.3.5 Express Shopper Subsystem
The Express Shopper subsystem also allows the PSS System to be used in a slightly different
manner than normal, and also helps retailers and shoppers reduce the amount of checkout time.
A self-scanning kiosk is installed near the express checkout lanes in the store. A customer picks
up a terminal, scans their items, and replaces the terminal into the dispenser slot. The customer
then proceeds to the PSS checkout lanes and presents their ticket or loyalty card to the cashier
who then performs a standard non-audit self scan checkout.
2.3.6 Electronic Marketing Subsystem
The PSS system also allows for a basic electronic marketing facility through the Electronic
Marketing subsystem. This application allows a retailer to send messages to a shopper’s hand
held terminal anytime that a given item is scanned.

2.3.7 User Messaging
Also, through the User Messaging application, the store has the option to send messages to
shopper’s hand held terminals. The messages can be any text, and can be made to be repeated, to
be displayed at fixed times during the day, and/or to be directed to any set of shoppers currently
in the store. In addition, messages can be "pre-loaded" such that they are displayed to the user
the next time they enter the store and use the PSS system.
2.3.8 Transaction Ticket Printing
The Transaction Ticket Printing application prints a transaction ticket for the shopper at the
conclusion of their self-scan shopping trip. The ticket is used to direct the shopper to the self-
scan or quick pay lanes. The ticket also provides a mechanism, when scanned, for notifying the
POS System that this is a PSS transaction. Using a transaction ticket is optional.
2.3.9 POS Interface
The POS Interface application provides the mechanism by which the PSS System can be fully
integrated into a store’s environment. It handles price file updates and Scan-In/ Scan-Out file
mechanisms.
2.3.10 System Administration
Further, a system administration application is provided which allows store personnel to adjust
and monitor the PSS system and data.
2.4 PSS Overview Diagram
The following diagram depicts the PSS Software in the context of a WaveWorks system. The
system hardware interfaces occur via the Spectrum 24 network. The hand-held terminal user
interfaces are managed as shown in the Application User Interfaces. The Web screens used at the
Service Desk Terminal interface via the Web Server. The Message Server routes messages
through the Business Server to COM objects that perform the PSS business logic and provide
any necessary database manipulations.

4. PSS Software Installation
This installation guide is intended to provide a roadmap for installing and configuring the PSS
system and all supporting software. The reader should be familiar with the Windows interface
and installing software.
This guide assumes the software is being installed on a new machine. It is strongly
recommended that the target computer be dedicated to running PSS and that you install the
software onto a freshly formatted disk.
Before Starting
The following media will be needed during the installation process:
- Bootable Microsoft NT Server Version 4.0 Installation CD
- NT “Getting Started” book (with the Certificate of Authenticity on the front)
- NT 4.0 Service Pack 5 CD
- NT 4.0 Option Pack CD
- Video and Network Card drivers
- Microsoft SQL Server 7.0 (Standard) CD
- Microsoft Access CD or Microsoft Office 97 Professional Edition CD
- Symbol PSS Setup CD (includes WaveWorks, PSS, and customer changes)
The following information will be needed during the install:
- Administrative account and password for the computer
- The IP address and hostname of the target computer. (It is suggested that the target
computer use a private IP subnet. The 172.16.N.N addresses are typically used with a
subnet mask of 255.255.255.0; this allows for 256 hosts on the subnet).
- The range of IP addresses to allocate for DHCP use. If you need to have the target computer
on the office/store network, make sure that there are no other DHCP servers on the same
subnet. If that is not possible, then install a second network adapter and use it to connect to
the outside world, leaving the private IP subnet for PSS use.
- Access Point ESS ID (aka Net ID)

4.1 Install NT 4.0 Server
The first step in the installation process is to install the NT 4.0 Server operating system. It is
strongly recommended that you do a clean installation of the entire system. Many of the more
expensive server PCs come with customized installation programs that walk the user thru the NT
installation process. If your PC comes with a special installation CD, you should use it, but read
this section first to identify the places where you will have to change settings from the default
values. This section describes the NT installation process using the standard Microsoft NT
Server installation CD.
Below are the specific steps to follow:
Turn the computer on. During the boot-up process, enter the CMOS setuphowever that
process occurs on your machine. Look for a message that says which key to press to enter Setup
(Delete and F2 are popular choices).
- Set the CMOS to boot from the CD-ROM drive.
- Insert the NT Server CD Installation in the CD-ROM drive, then exit from the CMOS
settings. The system should now boot from the CD.
- The blue “Windows NT Setup” screen is displayed. Wait while various system files and
drivers are loaded.
- The blue NT boot screen is displayed, then it goes back to the “Windows NT Server Setup”
screen.
- Press Enter to install Windows NT now.
- The Mass Storage screen is now displayed. This section of the setup process is hardware
specific. Most corporate PCs do not have SCSI interfaces installed in them. Many server
PCs do come with SCSI interfaces, so you’ll need to know what kind of hard disks your
system has before continuing. Press Enter to skip searching for SCSI devices. Press “S” to
check for them.
- The Licensing Agreement is displayed. Read the Agreement (press the Page Down key to
advance to the next page) until end of End User License Agreement (EULA) verbiage is
reached.
- Press F8 to accept the Licensing Agreement.
- The Server Setup screen is displayed which lists any previous installations of NT. Select
“N” to install a fresh copy of NT Server.
PSS Software Installation
______________________________________________________________________________
WaveWorks PSS, Integration Guide, 1.10 Page 15

- The Components list is displayed. Press Enter to accept the list of standard
hardware/software components.
- The Partition options screen is displayed. It is very important to pay attention to what you
are doing here. This section is also hardware specific.
- Start off by deleting all existing disk partitions. Select each existing partition (use the arrow
key to move the highlighted partition) and following the on-screen instructions.
- The screen should now only show “Unpartitioned space” since you just deleted all existing
partitions. The next step is to create a partition that NT will be installed onto. Depending on
the size of your hard drive, you’ll want to select a value between 2GB (2047 MB) and 4GB
(4095 MB). You will now create a system (C:) partition. Move the highlight to
“Unpartitioned Space” with the arrow keys. Press “C” to create a new partition and then
enter the partition size (a number between 2047 and 4095, consult your system administrator
if you need help).
- If your disk is 8GB or smaller, you can create a D: partition here. If your disk is greater than
8GB in size, the NT setup program can’t access all of it, so it’s best to wait until later to
create the D: partition. To create a D: partition, follow the same steps as for the C: partition,
with the exception that the size will be all the remaining space on the drive (the number is
already filled in for you by default). Typical installations might evenly divide a 6 or 8 GB
disk between the C and D partitions. If you expect the database to be quite large, then give
the D: parition more space than the C partition (but give C at least 2GB!).
- Put the highlight on the C: partition and press Enter to install NT on the C: drive
- The File System selection screen is displayed. The FAT file system is the default, but FAT
partitions are limited to a maximum size of 2GB and are not as efficient as the NT File
System (NTFS). Select the NTFS file system and press Enter.
- Wait while the system formats the C: drive. Note that the D: partition (if you created one)
does NOT get formatted at this step. Formatting a 4GB partition can take a while (10
minutes perhaps).
- The File location screen displays. Press Enter to accept installing NT in the \WINNT folder.
- The Hard disk examination screen displays. Press ESC to skip the exhaustive hard disk
check. The exhaustive check physically checks the entire hard disk surface and can take a
very long time, so we skip it.
- Wait while setup does a quick disk check.
- Wait while setup copies files to the disk.
- The Setup Successful screen is displayed. Remove the CD from CD-ROM drive.

“Certificate of Authenticity” on it.
- The Licensing Modes screen is displayed. Select “Per Seat”, then click on Next.
- The Computer Name screen is displayed. Enter the name of the computer. Note the name
must be unique to avoid confusion within your network domain. Then click on Next.
Contact your network administrator if you need help selecting a Name.
- The Server Type screen is displayed. Select the “Stand Alone Server” option, then click on
Next.
- The Administrator Account screen is displayed. Enter the Administrator Account password
(and the confirmation to ensure you typed it correctly), then click on Next.
- The Emergency Repair Disk screen is displayed. Select “No”, since one will be created later
(once the the system is completely configured). Click on Next to continue.
- The Select Components screen is displayed. In general, we try not load any “fluff” on the
server, so we will limit the amount of extra software we install.
- De-select all the options (no check mark) except for the “Accessories” and
“Communications” options.
- Highlight the Accessories option and click the Details button. Select all the components
listed. Select the OK button.

- Insert the floppy disk containing the NT drivers for your network card then click on OK to
search the disk.
- Select the proper driver from the list, then click OK to copy the driver files to the hard disk.
- The network card you just installed the drivers for should now be listed. Click Next to
continue.
- The Network Protocols screen is now displayed. Deselect the “NWLINK IPX/SPX”
protocol. Select the NETBui protocol. TCP/IP is required by the PSS system. NETBUI is
used by NT to access disk drives on other computers. Click Next to continue.
- The Network Services screen displays. Click on the “Select from list..“ button.
- Select the “Microsoft DHCP Server” service from the list, then click OK. The DHCP service
is a central resource that gives out IP addresses to other computers on the same network. The
terminals do not store IP addresses, so they ask DHCP for an IP address when they first
connect to the system.
- Note that DHCP Server is now added to the list of Network Services to install. Click Next.
- Click Next again to install the networking components.
- Wait while files are copied. Click OK on any status boxes that display.

clicking on the desktop icon and then selecting the Delete option.
- Right click on the “Recycle Bin” icon. Select Properties. Select the “Do not move files… “
option. Click OK. This step basically turns off the Recycle Bin and causes all files to be
deleted immediately. We find ourselves creating (and later deleting) large log files. If the
Recycle Bin is active, you won’t actually delete the file (and free up the disk space) until you
empty the Recycle Bin. So we turn it Off.
- Right click on the Recycle Bin icon. Select the “Empty Recycle Bin” option, then click
“Yes”. This step cleans out any files that were previously deleted and moved to the Recycle
Bin.
- Right click on the desktop and select the Arrange Icons submenu. Select the Auto Arrange
option. This step makes the icons arrange themselves automatically (top to bottom, left to
right). You may want to skip this step if you prefer to group desktop shortcuts all over the
place.
- Click the Start button. Select Settings, then Taskbar, then Small Icons, then OK. This step
keeps the Start menu smaller.
- Click the Start button, then Programs, then Windows NT Explorer. Select View Menu,
Folder Options, View Tab. These changes maximize the amount of information displayed in
the Explorer window.
- Select Display full path in the title bar.
- Select “Show Attributes” in Detail View.
- Select “Show Map Network Drive” button in toolbar.
- Uncheck Hide file extensions for known file types.

be scheduled to start below).
- Press OK.
- Press OK.
- Press OK.
4.9.4 Configure the Extensive Database Check and Backup job
This step will configure a database backup, and an extensive check of the integrity of all of the
structures in the database, including tables and table indexes, which will run once a week. The
integrity check takes a relatively long time because the structure of all of the table indexes must
be verified, and because of this, this activity must be scheduled for the time of the week with the
least shopping activity.
- Under ‘Management’, click on ‘Database Maintenance Plans’.
- In the right pane, right-click, and select ‘New Maintenance Plan...’, and the Database
Maintenance Plan Wizard should appear. Click “Next.”
- This maintenance plan will include an exhaustive optimization and validation of the
database, as well as a backup. It should run once a week when the system is unused, or
lightly used. The default schedule for these activities is Sunday in the early morning
hours. You should change this schedule only if necessary.
- On the Select Databases page, make sure ‘These databases’ is selected, and check the box
next to the PSS database name. Click ‘Next’.
- On the ‘Update Data Optimization Information’ page, click on ‘Reorganize data and
index pages’, and click on ‘Remove unused space from database files’.
- This operation may take some time, and slow down the system, so if you have a
reason to use a different schedule, then next to ‘Schedule’ press the ‘Change’ button,
and make the appropriate changes.
- Click ‘Next’.
- On the ‘Database Integrity Check’ page, click on ‘Check database integrity’. Click on
‘Perform these tests before doing backups’.
- If you have a reason to use a different schedule, you can change it by pressing the
‘Change’ button next to ‘Schedule’. Make any changes, and press ‘OK”.

directory under your SQL Server 7 installation directory, such as C:\MSSQL7\BACKUP.
In any case, you should make sure that the specified directory exists in Windows
Explorer, and create it if it does not (using File, New, Folder). Through normal
operation, the database, and therefore the backups, can eventually grow to be very large,
so make sure the space available will be sufficient.
- Click on ‘Remove files older than’, and change the data to the right to ‘2’ ‘Days’.
This value can be varied based on the amount of space available, and the number of
days of backups you wish to keep.

4.19 Load Initial Data
This step will populate the PSS database with the initial data needed for the system to run. The
PSS system is very much a data-driven system. It is CRITICAL that these scripts be run
correctly if you want the system to run properly. You can run a batch file that will run all the
scripts for you (the “Automatic” method), but it requires that the database is named “PSS”. If
you chose to use a different name for the database, you will have to run each script manually
using the Query Analyzer program or edit the BAT file to use the database name you used. The
Automatic method is the preferred method.
Automatic Method
- Open a command window (Start | Programs | Command Prompt)
- Change to the Pss\Database folder
- Run the Pss_Create_And_Init.bat file to create the PSS tables and fill them with data.
- Exit the command window
Manual Method
- Run the Query Analyzer program (Start | Programs | Microsoft SQL Server 7.0|Query
Analyzer)
- Connect to SQLServer (click on the “…” button).
- Select the “Start SQLServer if stopped” button, then click OK.
- Select the PSS database from the dropdown list.
- Run the following SQL files, IN ORDER, by opening them (File | Open), then executing
them by clicking on the green triangle. Pay attention to the status messages at the bottom of
the window. The message should read “Query completed without errors” if the script was
successfully executed. The following SQL files are found in the C:\Pss\Database folder (by
default):
- Pss_Drop_Db.sql (deletes all existing PSS tables, so backup any existing data first)
- Pss_Create_Db.sql (creates empty database tables)
- Pss_Init_Data.sql (loads default data)
- PosInterface_Dbinit.sql (loads POS interface settings)
- PosInterface_Text_Engus.sql (loads POS text strings in US English, the default language)

4.22 Configure Task Scheduler
This step creates processes that must run automatically at various intervals for the proper
function of the Portable Shopping System. If these tasks are not configured correctly,
certain features of the system, such as timed messaging, will not work, and the system
will eventually cease functioning.
- Double-click "My Computer" on the Windows Desktop. Once the "My Computer"
window appears, locate and double-click "Scheduled Tasks".
- There should be several tasks listed in the window ("Add Scheduled Task" is not a
task, but will allow you to add tasks to the scheduler, if desired).
- For each task:
- Double-click the task, and the task dialog should appear. Make sure the Task tab
is selected.
- In the "Run:" and "Start in:" fields, scroll across and make sure that all of the path
names that appear point to the correct PSS installation directory (C:\Pss).
- In the "Run as:" field, enter the local Administrator account (e.g.
MyMachineName\Administrator). Click the Set Password button, enter the
Administrator password in each of the two fields, and press OK.
- Press OK on the task dialog.
- To verify that the scheduled task can run correctly, right-click on the task, and
select Run. Scroll to the right in the Scheduled Tasks window, and make sure that
under the Last Run Time column, the current time appears, and that under the
Status column, no error messages appear. The task can then run successfully as
scheduled.

4.23 Configure Unit Management
This step establishes the configuration of the hardware needed for PSS. The exact
number of entries is specific for each installation, so you’ll need to know what your
hardware set up is. Use the Service Terminal screens to add entries or just directly type
them into the database using the SQL Server Enterprise Manager. If the hardware
configuration is a “standard” setup, then perhaps it would be wise to have an SQL file
that can be run from the Query Profiler instead of manually entering the data at each
store. Follow the order of data entry as shown. There are relationships between the
tables that require this order of creation:
- Create Power Supplies
- Each power supply can handle about a dozen devices. The Unit Management
logic uses the relationship between cradles and power supplies to prevent
unlocking more than one cradle per power supply. Enter one row for each power
supply in the PSS system.
- Create Entrances
- Create a row in the UMS_Entrance table for each entry station. The Entrance ID
is just a sequential number that is used to identify the Entry Station once it has
logged in. The Entry Station logs in using its MAC address (RF Entry stations) or
its service name (Ex. PssEntrance01) for serial entry stations. The MAC address
(or service name) needs to be entered in the Hardware ID field. If you have
multiple entrances you can set the backup entrance. The system will
automatically failover to the backup entrance when the entrance is set to Out of
Service.
- Create Printers
- Create a row in the UMS_Printer table for each printer in the system. The Printer
ID is just a sequential number that is used to identify the Printer once it has
logged in. The Printer logs in using its MAC address (RF printers) or its service
name (ex. PssPrinter01) for serial printers. The MAC address (or service name)
needs to be entered in the Hardware ID field. The system will automatically
failover to the backup printer when the printer is set to Out of Service.
- Create Dispensers
- Create a row in the UMS_Dispenser table for each dispenser in the system.
Dispensers are simply a logical group of cradles that are (usually) physically close
to each other. A dispenser is NOT a piece of hardware, although all the cradles
mounted on a particular piece of furniture may be called a dispenser. It is up to
the discretion of the integrator on how to best group cradles into dispensers. You

want at least one dispenser per entry station, but you may have multiple
dispensers per entry station. Customers are directed to a dispenser, so keep this in
mind when deciding how to group cradles into dispensers. Each dispenser is
controlled by a single entrance.
- Create Cradles
- Finally, create a row in the UMS_Cradle table for each cradle in the system. This
can be a time consuming process if you have 100 or more terminals and is a fine
reason to have a standard SQL script for configuring the UMS tables. Each cradle
has a location barcode sticker. Make sure that the cradle ID's you enter match the
barcodes exactly (i.e. if the barcode is a "0100", the cradle ID entered must be
0100). The stickers MUST be unique, but they do not need to be sequential. Be
careful to assign the correct power supply to each cradle.
Note: you do not need to create rows in the UMS_Terminal table for the hand-held
terminals. As terminals login to the system, rows are automatically created.

4.25 Configure the NBQMAIN Service (IBM 4690 POS Only)
If you chose the IBM4690 POS as your Point of Sale system, NBQMAIN service, which
is part of IBM’s Retail Connectivity Option(RCO), is a critical link between the PSS
system and the POS. The NBQMAIN service should be configured to startup
automatically when WindowsNT starts up. It is NOT controlled by the WaveWorks
System Controller. This section explains how to set up the service to automatically start
and how to configure the service.
You will need to make the NBQMAIN service auto-start at bootup. Go to
StartSettingsControl PanelServices and click on the “nbqmain” entry in the list.
Now click on the “Startup…” button (NOT the “Start” button). Select the Automatic
startup option and click on the OK button. Close the Services window.
The startup parameters, such as the POS controller name, LANA number and heartbeat
interval are contained in the NBQMAIN.CFG file in the PSS\Bin folder. You will need
to edit the NBQMAIN.CFG file to set these parameters to match your specific
installation. Default values are provided in the file.
The most likely parameter to be modified is the LANA number, which is specified with
the –a switch in the NBQMAIN parameters list. This number identifies which netbios
port to use for communication to the IBM4690 POS. The correct value for this parameter
is determined as follows:
From the Windows NT Start button follow the path
StartSettingsControlPanelNetwork.
Select the Services tab, then double-click the NetBIOS Interface
Note the lana number for the “Nbf” entry for the network card connected to the POS
network.
For more information on configuring parameters for the NBQMAIN service, start a DOS
command prompt session, set your path to C:\Pss\Bin and type the command:
nbqmain -?
Additional information is also available in the document Retail Connectivity Option
Version 2.2 , IBM product reference 5764-054.

5.2 Perform Initial Loading of Customer and Item Data
Both the IBM 4690 POS and the FileBased POS interfaces require the creation of flat ASCII
files of information for PSS to process. The formats and default filenames for the Item and
Customer files are documented in Appendix D of this document. Ultimately the POS should
create both of these file types for PSS to process. An Example Customer file and Item file are
provided in the PSS\PosTools directory for reference. See the readme.txt file in the directory for
more information on the files provided in that directory.
After other configuration steps have been completed and the PSS System has been started, a set
of test Customers and test items can be loaded into the system by placing the example Customer
and Item files into the configured Transfer directory(C:\Pss\Transfer). The PssFileMonitor
service will detect them and trigger the WaveWorks transaction to process them and load the
information into the PSS database.

6.2 Obtaining System Status Information
6.2.1 Viewing The System Log
The System Log screen allows you to view detailed information on events that have occurred in
the system; for example, to determine the cause when the system is down.
From the Main Menu, select System / Settings / Status / System Log.
This screen displays the following information:
• The dates and times that events occurred. The pages are ordered from the most current
event to the least current.
• The facility (part of the software) that performs a function. Examples are Unit
Management, Transaction Ticket, PSS File Processor, etc.
• Actions performed that are specifically related to the facility, such as Terminal Returned,
Print Receipt / Stub, POS transFile, etc.
• Severity code from 1-4 and 10, in ascending order of severity.
• Messages.
This System Log screen has several filter options for limiting the data display as follows:
• Display all events in a particular date / time range.
• Display all events associated with a particular facility within a date / time range.
• Display all events associated with a particular action and date / time range.
• Display all events with a particular severity code and date / time range.
• Display all events with messages containing typed-in words or phrases.
• You can also display data with all of the above filter options or select a date / range and
any other one or more of these options.
Note: The data in the log can be limited or expanded by setting the “trace level” of a particular
system facility (function) to a particular level. Trace levels are set in the PSS Settings screen. If
the trace level for the Quick Order function is set to 2, for example, the system will save
information at level 2 and above, but will not save errors to the log that are beneath that level.
The lower the trace level, the more details on the function are saved in the log.
Trace levels are displayed on the log under the title Severity Level. If problems occur with a
facility of the system, you can view the severity level for that facility and decide to lower the
trace level so that future events relating to that facility will be saved in the log.

8.2 Unit Management Subsystem
The Unit Management Subsystem (UMS) manages the Symbol hardware devices that comprise
the PSS system. Those devices include hand held terminals, cradles, entrance unit devices, ticket
printers, and power supplies. Since UMS manages hardware, it is important to understand each
of the devices being managed in both the Asterix2 and Asterix3 versions of PSS.
8.2.1 Hardware Overview
Terminals
The PSS system only uses RF terminals. PSS can use either Asterix2 or Asterix3 terminals. The
Asterix2 terminal has five buttons and a 4 x 20 display. The Asterix3 terminal has four buttons
and a trigger (in lieu of the “+” key on the Asterix2), and an 8 x 20 display. Both terminal types
charge their batteries while in the cradle, but since the Asterix3 uses a newer lithium battery, the
battery-related constants are different for the two terminals.
Cradles
The cradles are completely different between the Asterix2 and Asterix3 systems. The Asterix2
terminals are placed into an integrated eight-slot rack, and as a result, the entire system is
comprised of terminals in multiples of eight. When the Asterix2 is unlocked, a small light on the
face of the terminal is lit. The Asterix3 cradles are individual units, and the entire system can
include any desired number of terminals. When the Asterix3 is unlocked, the cradle housing
lights up. The Asterix2 cradle locks the terminal tightly against the contacts. The Asterix3
cradle does not--which causes a number of issues, since the terminal can be lifted off the contacts
before the latch stops it.
Dispensers
In a typical Asterix2 system a module was a large plastic device that had eight integrated cradles.
Four modules were a unit. A dispenser in the Asterix2 world consisted of one or more modules.
The Asterix3 system uses individual cradles that can be physically arranged however the
customer wishes. An Asterix3 dispenser is simply a logical group of cradles (that are usually
physically adjacent to each other).
The concept of a dispenser being a logical group of cradles also works for Asterix2 systems as
long as the cradles in the same module are part of the same dispenser (to avoid confusing the
customer). So, in this document, a dispenser is really a collection of cradles, not a physical
device.
Software Description

WaveWorks PSS, Integration Guide, 1.10 Page 77

Entrances
There are two types of entrance stations: serial and RF. Either type can be used with either
terminal type, but the older serial entrance units are typically used on Asterix2 systems and the
newer RF entrances are used with the Asterix3 terminals. The primary difference between them
is how they are controlled from the host.
The serial entrance units are controlled by NT Services (one service per entrance unit). These
services are named “PssEntrance01,” “PssEntrance02,”, etc. These services are WaveWorks
clients and directly control the entrance display and process input. The RF entrance units
communicate with a single instance of an NT service (EhtService) that translates STEP
commands into low-level commands the hardware can understand. DisplayServer scripts handle
the screen display and input processing.
Printers
Transaction tickets are (optionally) printed at the conclusion of a self-scan shopping trip. The
ticket is used to direct the shopper to a quick pay or rescan lane and also as a means of
identifying the shopper to the POS system. Transaction tickets are an optional feature of the PSS
system. PSS supports three types of ticket printers: RF rack, serial rack, and serial service
terminal. For installations that do print tickets, a printer is needed at the return rack and at the
service terminal.
Power Supplies
The PSS system also manages power supplies. There isn’t much to manage aside from ensuring
that only one terminal per power supply is unlocked at a time. Unlocking more than one
terminal at a time could cause the power supply to fail. Power supplies normally have a status of
Ready (status code = 0). If a terminal that is powered by the power supply is being unlocked, the
status is set to Reserved (status code = 1). If all the terminals attached to a power supply report
that they are on battery power, then the power supply status is set to “Check Hardware” (status
code = 6) to indicate that perhaps the power supply has failed or is unplugged.
8.2.2 Software Components
The Unit Management subsystem consists of the following software:
Unit Management COM objectprovides all the UMS business services. The services
maintain data on hardware status, battery level, and terminal location. The services also send
commands to the hand held terminals while they are in the dispenser. The UMS transaction
model (description of all UMS transactions) is found in the Appendix.
Entry Station Serviceuses PSA’s Hardware Isolation Library (HIL) to communicate with the
Entrance Station hardware devices (serial entrance stations only).
Software Description

WaveWorks PSS, Integration Guide, 1.10 Page 78

Printer ServiceUses PSA’s Hardware Isolation Library (HIL) to communicate with serially
connected printers.
UMS DisplayServer Interfacecontrols the display on the hand held terminal and also
provides procedures for handling input from the terminal and commands the UMS COM object.
EHT DisplayServer Interfacecontrols the display on RF entrance units and provides
procedures for handling input from the entrance.
8.2.3 Database Access
The Unit Management COM object maintains the following database tables. Refer to the Data
Dictionary in the Appendix for a description of the tables:
UMS_Entrancemaintains state information on entrance unit devices
UMS_Printermaintains information on printer devices
UMS_Terminalmaintains information on hand held terminals
UMS_Dispensermaintains information on dispensers (groups of cradles)
UMS_Status_Codelist of valid status codes for UMS devices
UMS_Terminal_Typeslist of valid terminal types
UMS_Cradlemaintains information on terminal cradles
UMS_Powermaintains information on power supplies
UMS_Card_Reader_Typemaintains a list of supported card reader types and properties

8.3 Shopping Trip Subsystem
Once the shopper retrieves the proper hand held terminal from the dispenser, the Shopping Trip
Subsystem allows the shopper to add and delete items from their basket and view the total
amount and number of items scanned during their current shopping trip. Shopping trips can be
ended by returning the hand held terminal to an empty dispenser slot or by scanning an “End of
Trip” barcode. Each activity during the shopping trip is logged and available for review from the
Service Terminal.
8.3.1 Start of Shopping Trip Processing
When a customer “swipes” their card to reserve a scanner to go shopping, the system will
perform the following:
1. ValidateCustomerverifies the following:
• that the customer is in the Pss_Customer database table and is not suspended;
• that the customer has no outstanding transactions (in the Pss_Shopping_List table), and
• that the card has no current shopping trips (in the Pss_Session table).
2. CreatShoppingListinitializes the tables Pss_Shopping_List, Pss_Session, and
Pss_Shopping_Activity.
3. StartShoppingTripoccurs at removal of the scanner from the dispenser.
4. GetTextretrieves all text necessary for display to the shopper (in the shopper's language).
8.3.2 Shopping Trip Processing
For Asterix 2 terminals, the "+" key is a physical key on the scanner; for the Asterix 3 terminals,
the "+" key is the trigger. The "-" key is a physical key on either terminal.
After the shopper scans a barcode, the following steps are taken in the StepServer Script
procedure ProcessInputData to process the barcode:
1. Parse the barcode
• A call to PssSpecialBarcode to break up the scanned input field into its disparate parts
• Modifications to the barcode from what was reported as scanned to what is needed to
compare into the item table
• Determination of whether a barcode is a “special” barcode that requires special handling
(e.g. the End of Trip barcode)
2. If, in the output from the above method, a “special” barcode is encountered, it is specifically
handled
Software Description
______________________________________________________________________________
WaveWorks PSS, Integration Guide, 1.10 Page 80
© 2000, Symbol Technologies, Inc. February 1, 2000
3. If, in the output from the above method, an item barcode is scanned, then the
AdjustShoppingList method is called to add or delete the scanned barcode from the customer's
shopping list. Any anomalous output from this method is handled via error screen displays (i.e.,
exception items, invalid barcodes).
The following is the database activity for a "+" or "-" key event:
1. Retrieve customer data from Pss_Customer table.
2. Verify input barcode.
3. Determine if it is a variable weight barcode using the Pss_Barcode_Variable_Weight
- if variable weight, get the price and item Id
- else use the scanned barcode and data from the Pss_Item table to execute the pricing
algorithm
4. Add the item to the shopping list ("+") or remove the last scanned match for this item id ("-") in
the Pss_Shopping_Item.
5. Calculate the total tax from the Pss_Tax_Table and Pss_Tax_Table_Entry and write the value to
Pss_Shopping_Tax.
6. Read for marketing messages from the Pss_Marketing_Item, Pss_Marketing_Department, and
the Pss_Marketing_Mfg tables and write to the Pss_Marketing_Sent table any messages sent to
the shopper.
7. Convert pricing values using the Pss_Currency table.
8. Write the total to the Pss_Shopping_List table.
9. Record the event into the Pss_Shopping_Activity table.
Anomalous conditions encountered in this process will be logged to the Pss_Message_Log table.
If the scanned item Id is not in the Pss_Item table, then record this in the Pss_Uknown_Item
table.
All text used throughout the shopping trip is stored in the Pss_Text table and is accessed through
a language Id associated with the customer or store.

Describe what happens when a customer presses the “=” key to view the summary.
The shopper presses the "=" key, and in the StepServer script procedure ProcessInputData, a call
to one of the ShoppingTripList functions is made. This will return character strings with item
Ids, descriptions, and prices (see COM object definitions for full parameter list). These strings
will contain all items currently in the customer's basket in a pipe-separated format. The lists are
controlled through the pss_system_setting database table. Based on these settings, display field
size, list order (ascending or descending), and contents of the list are established for consistent
display to the shoppers. All database access is “read only,” with the exception of an insert into
the Pss_Shopping_Activity table to record the event.
The following libraries and COM Objects are available for the shopping trip subsystem to use:
PssActivityCom COM object interface that allows activities to be added to the
Pss_Shopping_Activity database table to record shopper key presses and any other
event.
PSS ActivityLib This library handles the database insert, deletion, and retrieval of
Pss_Shopping_Activity database table rows.
PssBarcodeLib Library that interprets the barcodes scanned by the shopper. Has methods to
calculate and strip off check digits, determine barcode type (i.e., UPC, EAN13),
etc.
PssConfigurationLib Library used to access the database table Pss_System_Settings that contains the
client-selected configuration options.
PssPricingLib This library provides the core of the pricing method algorithms as defined in the
appendices.
PssShoppingTripLib Library that handles the database insert, deletion, and retrieval of
Pss_Shopping_List and Pss_Shopping_Item database table rows.
PssShoppingTripCom This is the COM object interface allowing
• shopping trips to be started,
• items to be added and removed from shopper’s lists,
• lists to be formatted for shopper review,
• shopping trips to be ended,
• as well as a series of general support functions (such as validating the

The following user exits are called during shopping trips:
UE_PreRescanDetermination Allows modification of the rescan calculation data prior to the
calculation, or allows wholesale replacement of standard rescan
calculation with a customized algorithm
UE_PostRescanDetermination Allows modification of the result of a standard rescan calculation
UE_PreProcessMarketingMessage Allows additional item marketing messages to be allowed /
disallowed prior to the standard method’s retrieval
UE_PrintReceipt On End of Trip, allows modification to the receipt file to be printed
on the ticket
UE_PostProcessIsVariableWeight After an item has been determined to be an embedded price / weight
item (or not), custom code can be added here to modify the decision.
If using the End of Trip barcode feature, configure any type of barcode with a check digit to be
the End of Trip barcode. The Pss_Special_Barcode table should contain the End of Trip value.
8.3.3 End of Shopping Trip Processing
This can happen in one of two ways depending upon the Pss_system_Settings database table
values. Either the shopper scans a predetermined End of Trip barcode (as specified in the
Pss_Special_Barcode table) or places the scanner back into the dispenser.
If an End of Trip input is recognized (either an “E” from the dispenser, or and End of Trip
barcode), the StepServer script procedure EndOfTrip is executed. This simply calls the
PssShoppingTripCOM object method EndShoppingTrip and then handles the resetting of the
shopping list status (if the scanner was in Queue Buster mode), then proceeds to the final Thank
You screen.
Within the EndShoppingtrip method, the following is done:
1. The customer data and shopping trip data are examined to determine if the trip is to be rescanned
or not.
2. The transaction barcode is calculated.
3. If enabled, the PssTransferFile is written with the list of items scanned by the shopper.
4. If enabled, the printer is requested to print the transaction ticket.
5. Customer and Shopping Trip data and status are updated.
6. Session data is deleted or modified if in queue buster mode.
7. Data in the database tables related to the shopping trip are deleted, such as Pss_Order_List_Item,
Pss_Order_List, Pss_Marketing_Sent and Pss_Shopping_Tax.

8.3.4 Shopping Trip Message Log Entries
This describes the log messages found in the Pss_Message_Log table that originated within the
Shopping Trip. The text shown here is in English, since the inclusion of all language text for all
messages would be excessive. This text is configurable in the database table Pss_Text, so if a
message is not here or not exactly as stated here, then the database table probably has changed.
All text is accessed through the GetText method, which accepts the Text_Id as an input
parameter.

8.4 Quick Order Subsystem
While shopping, a user may choose to place a quick order through the Quick Order subsystem.
The shopper identifies, through the quick order mechanism, the products and the
quantities/weights of those products they wish to order. The quick order can then be sent to the
appropriate department, where a web screen displays to store personnel the orders placed by
shoppers. After they have finished processing the order, store personnel can send a message to
the shopper that their order is ready. This is an optional feature.
PssQuickOrderBarcodeCom – Com object associated with quick order
PssQuickOrder – Class associated with quick order
Database tables associated with quick order are:
Pss_Order_List
Pss_Order_Status
Pss_Order_List_Item
Pss_Department
8.5 Queue Busting Subsystem
The Queue Busting application allows the PSS System to be used in a slightly different manner
than normal, but also helps retailers and shoppers reduce the amount of check–out time. Any
hand held terminal which has been released can be used for queue busting. This is normally
done by store personnel to alleviate long check out lines which may have formed.
Transactions in this mode are initiated by scanning a special (configurable) barcode. More than
one barcode can be configured for use in this manner. This barcode is expected to be on a plastic
token. Once the special barcode has been scanned, the items in the customer basket are scanned.
A PSS transaction is created in the same manner as a normal PSS transaction. After all items in
the basket have been scanned, the special barcode, which began this mode, is scanned again.
This transaction is sent to the POS System. The plastic token containing the barcode is then
handed to the customer with instructions to give it to the cashier at the check-out register. When
the customer reaches the register, they present the token and their loyalty card (if used) to the
cashier who then performs a standard non-audit self scan check out. After the customer checks
out, the token can be reused for other customers.
There are no methods written specifically for queue busting. The hand held application
differentiates between a normal shopping trip and a queue busting session.
PssSpecialBarcodeCom – Com object associated with queue busting
PssSpecialBarcodeLib – Library associated with queue busting
Associated database tables are:

8.6 Electronic Marketing Subsystem
The PSS system also allows for a basic electronic marketing facility through the Electronic
Marketing application. This application allows a retailer to send messages to a shopper’s hand
held terminal anytime that a given item is scanned. This is an optional feature.
PssEMarketingMessage - Class associated with electronic messages
ElectronicMarketing – Library associated with marketing
Database tables associated with marketing messages:
PSS_Marketing_Item
PSS_Marketing_Sent
PSS_Marketing_Mfg
PSS_Marketing_Department
8.7 User Messaging Subsystem
Also, through the User Messaging application, the store has the option to send messages to
shopper’s hand held terminals. The messages can be any text, and can be made to be repeated,
be displayed at fixed times during the day, and/or can be directed to any set of shoppers currently
in the store. In addition, messages for a particular customer can be preloaded and are delivered
to them the next time they shop with the WaveWorks PSS system.

8.8 POS Interface Subsystem
The WaveWorks PSS POS Interface is a file-based mechanism that provides communication
between the PSS system and the store POS system by the exchange of files.
PSS software monitors and deposits files into a directory referenced as the Transfer Area.
Inbound files (created by the POS) are detected in the Transfer Area and moved into the working
area where a processing transaction processes the information in the file. When processing
completes, the file is then moved into the Processed Files Area. Outbound files (created by PSS)
are initially created in the working area and, when completed, are moved into the Transfer Area
to be processed by the POS system.
Under normal operating conditions, files should only exist in the Transfer and Working areas
temporarily. If files begin to accumulate in either of those areas, it is a sign of a system
malfunction. Files moved into the Processed Files Area remain there until a File Housekeeping
job deletes them. Files which are processed correctly are renamed with filetype "COMPLETED"
and files which could not be processed are renamed with filetype "ERR".
The directory location of the Transfer Area and the Processed Files Area may be configured in
the PSS System Settings, but they default to the "Transfer" and "Processed" subfolders of the
folder where PSS was installed: (C:\Pss\Transfer and C:\Pss\Processed). This Transfer Area
folder location is identified by System Setting value POSINTERFACE/Local_TransferArea.
If the POS system supports network file paths and WindowsNT can be configured to map a
directory on the POS, then PSS can be configured to retrieve and send files to a directory area on
the POS system. The Processed Files Area is identified by a System Setting value
POSINTERFACE/ ProcessedFileArea. Since this folder can accumulate large numbers of files
depending on how frequently File Housekeeping is configured to run, this directory may be
configured to be on a different disk device than the disk on which PSS is installed. This would
be done to avoid filling up that disk and causing a Disk Full problem.

8.8.1 POS Interface Files
The files defined are:
• PSS Transaction filesent from PSS to POS to identify a shopper and the items they have
scanned.
• POS Transaction filesent from POS to PSS to identify that a shopper has paid for their
trip and allows for sending the items scanned by the POS system.
• Item Record filesent from POS to PSS and contains all of the items in the POS database
such that the PSS database can be updated to reflect the items contained in the POS
database.
• Price Changes filesubset of the Item Record file, processing is the same.
• Tax Table filessent from the POS to PSS and contain tax information used by PSS to
perform transaction tax calculations.
• Customer Update Filesent from POS to PSS to update the PSS database with
information about valid PSS shoppers.
The following sections describe the file layout for each of the file types.
(File layouts unchangedskipping to next section)
8.8.2 POS Interface Software Entities
The following software components are included to process the files listed above. A service
exists which monitors a specific folder for the arrival of these files. Files created by PSS are,
when detected, transferred to the POS system using the configured “transfer” transaction. Files
created by the POS system are, when detected, “processed” on the PSS system using the
configured “processing” transaction.
8.8.2.1 PSSFileMonitorSvc
PSSFileMonitorSvc is the service which monitors Transfer Area for the arrival of files from the
POS system and for files generated by the PSS system. It moves inbound files into the Working
Area and, when appropriate, initiates WaveWorks transactions for performing file-processing
functions. It can also be configured to initiate transfer transactions when it detects outbound
files. Release 1 of PSS provides no transfer transactions for sending files to a POS system.
8.8.2.2 PssPosService(IBM 4690 POS only)
This is an NT Service specifically developed for information exchange with IBM 4680/90 POS
systems running the Supermarket Application(SA). This service handles the transfer function for
all of the file types listed above.

8.8.2.3 IBM RCO for 4680/90 POS
PssPosService makes use of the IBM RCO (Retail Connectivity Option) product for the 4680/90
POS. Release 1 of PSS WaveWorks used IBM RCO release 2.4.1. This product supplies a
client access service that communicates with a Server application on the 4680/90 POS. For this
mechanism to work, the IBM POS must be running the adxsrvnl.286 application as a background
application. The client application nbqmain.exe that runs as a WindowsNT service is
automatically installed by the PSS installation procedure, but it must be configured by placing
configuration information into file nbqmain.cfg in the Pss\bin directory. This file is delivered
with a set of preconfigured values that are typical of a PSS/4690 POS installation, but may need
to be changed to allow PSS to communicate with the POS. See the IBM RCO User's Guide for
parameter values which can be placed in this file.
8.8.2.4 POSInterfaceCOM
This COM object contains the software methods used to perform the processing of transaction
files, item files, and tax table files described earlier. In release 1 of PSS, it also contains the
transactions which initialize the PssPosService. It contains the following functions to handle the
associated transaction:
Function Transaction Activator
LoadPOSItemFile P2P003 PssFileMonitorSvc
LoadTaxTable P2P005 PssFileMonitorSvc

8.8.2.6 PssFileMaintCOM
This COM object handles general file housekeeping functions. It contains the transaction used
by the POSInterface to purge files from the Processed File Area, the transaction to move the
PssTransactionFile from the Transfer area after the POS has processed it, and the transaction that
emulates the POS (Converts PSSTransactionFile to POSTransactionFile)
It contains the following functions:
Function Transaction Activator
CleanupPssTransFile P2P201 PssFileMonitorSvc
CleanupArchiveArea P2P298 WindowsNT Scheduler/WaveWorks
SENDTX
ConvertSItoSO P2P299 PssFileMonitorSvc
8.8.2.7 Windows NT Scheduler
PSS uses the native scheduler inWindowNT to schedule a purge of files from the
ProcessedFileArea area. During PSS installation, a scheduled task named PurgeFiles is placed
in the Windows NT \Tasks folder which is scheduled to activate transaction P2P298 daily to
purge the files. The FileHouseKeeping system settings are used to control the purge activity.
8.8.3 POS Interface Configuration
Configuration of the POS Interface for a specific store environment is achieved by modification
of PSS System Settings and by implementation of User Exit routines supported by the POS
Interface Applications. Changes to configuration items are made using the System Settings page
on the System Administration Terminal. That page contains a detailed description of each
system setting item with information that identifies valid values for the item. The page also
contains a default value for each item.
The settings for the POS interface are divided into the following four areas
• settings that apply subsystem-wide to the POS interface
• settings that apply to the processing of specific file types
• settings that affect the operation of the NT Services used by the POS Interface
• settings that apply to a specific POS system (IBM 4680/90).
After modifying a system setting value, the link at the bottom of the system-setting page,
Re-Initialize PSS System, must be activated to cause the modified setting to be recognized by the
PSS software. The PssPosService must be stopped and restarted after changing any
4POSSINTERFACE settings.

8.8.4 PSSTransactionFile Processing
8.8.4.1 File-Based Interface
At the conclusion of a shopping trip (when a hand held terminal is returned to the dispenser or
the End of Trip barcode is scanned), a PSS transaction file is created and placed in the transfer
directory. Once the file is properly placed in the transfer directory, the processing for a PSS
transaction file is complete in the file-based interface. Custom code must be developed to
provide the transfer mechanism to the POS system.
8.8.4.2 4680/4690 Interface
The IBM SA Personality implementation of the POS API uses the IBM product RCO. The RCO
API provides access to the POS files on the POS controller over a LAN. It is described in the
IBM manuals:
• “Retail Connectivity OptionVersion 2.4.1 including OS/2 appendix - Product Reference”
dated September 15 1994.
• “Retail Connectivity OptionVersion 2.3 - User’s Guide” dated November 1996, which
covers both OS/2 and NT
The POS Interface consists of a service (PssPosService) that includes a modified version of the
POSAPI from Version 5.0 of the PSA. The POSAPI provides the interface between the PSS
Controller and the native 4680/90 POS. It provides the PSS Controller with file access to data on
the native POS controller.
When a hand held scanner is returned from a shopping trip, a PSSTransactionFile, according to
the format listed above, is created in the transfer directory. The PssPosService scans the transfer
directory at a regular interval. On detection of a file, the PssPosService handles transfer of the
information in the transaction file to the 4690 controller by writing the transaction information
into the Scan-In file on the POS. The frequency at which the PssPosService scans the directory
is specified by the system setting PSStransactionFile/MonitorInterval.
8.8.4.3 POS Emulation (Demo System)
Under normal conditions, the PSS shopping trip creates PssTransaction files and places them in
the transfer area for a POS to process. The PssFileMonitor process is configured to ignore these
files and not attempt to move them or process them, since the store POS (PssPosService) will be
processing them. For testing and demonstration purposes, when access to a POS system is
unavailable, the System Setting values for the PSSTransactionFile can be modified to cause the
PssFileMonitor to detect them and activate a POS emulation transaction. This transaction reads
PSSTransaction files (Scan-In) and creates corresponding POSTransaction files (ScanOut) which
are in turn detected and processed to complete the full shopping transaction cycle and unsuspend
the customer record (customers are suspended until trips are completed).
Software Description
______________________________________________________________________________
WaveWorks PSS, Integration Guide, 1.10 Page 100
© 2000, Symbol Technologies, Inc. February 1, 2000
In order to enable this feature, the following system settings must be configured as shown.
Name/Subname Value
PSSTransFile/TransferEnabled Y (Tells PssFileMonitor to process this filetype - default is N)
PSSTransFile/TransferTX P2P299 (the PosEmulation transaction -default is P2P199)
PSSTransFile/AddCustCheckDigit N (should match value for POSTransFile/RemoveCustChkdigit)
PSSTransFile/AddCustItemDigit Y (should match value for POSTransFile/RemoveItemChkdigit)
After changing these settings, stop both the PosService and PssFileMonitor services. Set the
WaveWorks database ADM_DAEMON table so that PosService is NOT restarted automatically
(just prefix the name so the service isn't found). This will prevent the PosService process from
trying to process PssTransaction(ScanIn) files.
Start up the PssFileMonitor service. By setting the values above, PssFileMonitor will be enabled
to monitor PSSTransaction(ScanIn) files and trigger event P2P299, which creates a
corresponding POSTransaction(ScanOut) file. Normal POSTransaction file processing will then
be triggered by the appearance of a file and cause the shopping trip to be completed.
The POSTransaction file that is created has the same RESCAN flag value and the same items as
are in the PSSTransaction file. Future support for record level and file level user exits to be
called by transaction P2P299 is planned. Thus the created POSTransaction file could be altered
by integrators to add to, remove, or alter records. This support is not available in the initial
release.
8.8.5 POS Transaction File Processing
8.8.5.1 File-Based Interface
The transfer directory is polled by the PssFileMonitor service. Once a POSTransactionFile
arrives in the transfer directory, file processing is activated. The shopping trip information is
moved into the Shopping History database tables. In addition, the shopper's rescan probability is
recalculated. If the file contains an End of Day record, the End of Day Event is stored in the
database (PSS_EOD table) and the End of Day user exit routine is activated.
8.8.5.2 4690 Interface
Upon completion of a transaction at the store check-out lane, a 4690 user exit running in the
check out support application updates a ScanOut file on the POS with information about the
completed transaction. The PssPosService polls the file on the POS, retrieves new information
in the scan-out file, and creates a PosTransactionFile in the Transfer Area for each POS
transaction completed since the last scan. Upon detection of a POS transaction file by the
PssFileMonitor service, processing continues as described in the file-based interface. The
frequency of the poll interval is specified by system setting POSTransactionFile/MonitorInterval.

8.8.6 Item Record File Processing
PSS maintains a database of items on the store shelves and their prices. This database is
maintained by downloading the item information from the store’s POS system. These
downloads can be achieved as either full item database downloads or as item information
updates.
The POSItemFile system settings are used to control the functioning of these operations. Either
or both download types can be used to update the PSS item database. Since a download of a full
item file requires a high level of computer system resources it is recommended that full item
database downloads be performed when shopping activity is low. However, shopping trip
activities may continue during Item File processing and full downloads or updates can occur at
any time. Early benchmarks indicate approximately 1500-4000 records per minute can be loaded
depending on other PSS system activities, load on the POS system, overall traffic load on the
PSS-POS network segment, machine configuration (CPU speed and amount of memory) and on
the database size.
There is one primary distinction between item update and full item file processing, item deletion.
During full item file processing PSS tags all items in the database that were also in the item file
and after finishing its update pass it deletes all untagged items. Since item update processing
does not include an item delete function, this is the only way to purge PSS of items that have
been deleted from the POS database.
8.8.6.1 File-Based Interface
The transfer directory is polled by the PSSFileMonitor service. When a Full Item File or
Item/Price Update file arrives in the transfer directory, the Item File processing is initiated. File
processing takes the data contained in each Item File record and loads that data into the
PSS_Shopping_Item table in the PSS Database.
8.8.6.2 4690 Interface
The PssPosService creates an Item update or full Item file from the information maintained on
the 4690 controller. On startup, the PSSFileMonitor service sends a WaveWorks transaction to
the PssPosService requesting that it initiate Item/Price update processing. The PosService then
begins polling the POS controller at the rate specified by the configuration item
POSItemFile/MonitorInterval for changes. The PSSFileMonitor uses the configuration item
POSItemFile/TransferTime to control when to request download of a full item file to the PSS
system. When that time arrives, the PSSFileMonitor sends a pair of WaveWorks transactions to
the PosService, one to disable item/price update polling and one to request creation of the full
item file. On arrival of the item file in the transfer directory the PSSFileMonitor triggers the
WaveWorks ItemFile load transaction. Upon completion of loading the file, the ItemFile load
module sends a WaveWorks transaction to the PosService to tell it to resume polling the POS
system for updates.

8.8.7 Customer Update File Processing
The information maintained for customers that are registered to use the PSS system may be
updated by sending a Customer Update File to the PSS system. This file can be used to create
and update customer records in the PSS Customer database. PSS maintains many data items not
included in the CUSTMTxx.DAT file described earlier in this document, but the format has been
maintained for compatibility with existing PSA systems. Sites, which choose to populate
additional PSS customer fields, can append data to the customer record in the User Expansion
Area of the record and can process that data by customizing the User Exits provided.
8.8.7.1 File-Based Interface
The transfer directory is polled by the PSSFileMonitor service. When a Customer Update file
arrives in the transfer directory, the file processing transaction is activated. File processing takes
the data contained in each Customer Update record and loads that data into the PSS_Customer
table in the PSS Database.
8.8.7.2 4690 Interface
There is no special support provided with the base PSS system for creation and transfer of
customer files.
8.9 PSS Services
Services are software programs that control individual components of the Portable Shopping
System (there are also services concerned with the operating system and other components of
your computer). The common services associated with the Portable Shopping System are
defined below; your store may have additional custom services not listed here.
WaveWorks RF Server—handles all communications to RF devices (primarily the hand held
scanners, and certain types of entrance units)
WaveWorks Message Server—routes messages between components of the system
WaveWorks Business Server—manages software applications (COM Objects)
WaveWorks STEP/Display Server—displays the screens on the hand held scanners
WaveWorks System Controller—the highest level service which encompasses all other services
defined for your installation of the PSS

9. Customizing the PSS System Software
The WaveWorks PSS system offers a number of options for integrators that need to customize
the base system to meet customer requirements. PSS allows integrators to customize the system
by changing the DisplayServer scripts, writing custom services, or writing custom business
objects. PSS also supports “user exits,” which are function hooks in the base code that let the
integrator provide custom processing at key points in the code.
9.1 Custom DisplayServer Scripts
The DisplayServer process runs scripts called “interfaces” that control the display on RF devices
(terminals and RF entrance units). The code for the interfaces is stored in the WaveWorks
database. The source files that were used to load the database at install time are found (by
default) in the C:\PSS\StepDev folder. The integrator can make a customer-specific copy of
these source files and modify them as needed. The modifications can range from small changes
to the logic, such as running a custom transaction or changing the screen layout, to completely
rewriting the interface. Note that most interfaces get their text from the PSS database, so
changing the wording of prompt or message may be as simple as changing the text in the
PSS_Text table.
9.2 Custom Services
The PSS system uses NT Services (standalone processes that are started at bootup) to
communicate to hardware devices. Examples include the EhtService for communicating with
the RF entrance unit, PssPrinterXX for talking to serial ticket printers, and the PssPosService for
talking to the store’s POS system. Writing an NT service requires a solid programming
background and WaveWorks developer training, but is an option for providing an interface to
special devices or computer systems. The services connect to the WaveWorks MessageServer
and use WaveWorks transactions to access standard business services.
9.3 Custom Business Objects
PSS business services are contained in more than a dozen COM Objects. Each business service
is a COM object method. The WaveWorks system uses transaction Ids to map business services
to a particular method on a particular business object. Integrators don’t have access to the base
system source code (aside from user exits that are implemented in the COM Objects), but they
can create their own COM Objects. These COM Objects can provide new business services
(using new transaction Ids) or replace existing business services (by changing the mapping
between transaction ID and COM object/method in the WaveWorks database). These new
business services can be accessed from custom services and custom DisplayServer interfaces.
Customizing the PSS System Software
______________________________________________________________________________
WaveWorks PSS, Integration Guide, 1.10 Page 105
© 2000, Symbol Technologies, Inc. February 1, 2000
Writing custom COM Objects requires a solid programming background, preferably using Visual
C++ and the ATL wizard.
9.4 User Exit DLL
A DLL, PssUserExits.dll, is provided which allows integration teams to customize the software
for a given installation. This mechanism is equivalent to the User Exits used in the PSA
software. The DLL contains functions that have been built into the code, but that, in most cases,
contain stubs that only log a debug level message to identify that the function was called. The
integrator is then allowed to add appropriate code to the functions and rebuild the dll.
The C++ language header file PssUserExits.h documents the intended purpose of each function,
the detail of the function interfaces, and the return status codes expected by the base PSS
software. It also documents how the various return code values will affect the operation of the
base PSS software when the function returns.
Each User Exit function is implemented in a separate C++ source file named
<UserExitName>.cpp. This C++ source file contains the stub code for the function.
9.4.1 Common Information
All methods should return one of three return status codes as described below. The return code
is the last argument in the call list to the User Exit function.
The following description of standard arguments which are passed to all user exits applies to
C++ modules only. User Exits called from "C" only code will not include the arguments which
are C++ objects.
A C++ source module with the same name as the function name is supplied with a stub
implementation routine for the User Exit. The stub routine "includes" the PssUserExits.h file to
retrieve the function definition. All stubs return status UE_CONTINUE to the calling routine.
Many of the stub routines log a debug level message to the PSS System Log with the values of
all the input arguments. This stub code can be reviewed to see how to use the CPssMsgLog
object to write messages to the PSS System Log. See also the following section "Using the
CPssMsgLog Class."
If a "Preprocess" User Exit needs to pass information to a "Postprocess" User Exit for the same
PSS function (PreProcessRecord -> PostProcessRecord), it can be maintained in static storage in
the dll. All other information exchange between user exits cannot safely rely on executing
within the same instance of the dll. In those cases the User Exits must use other mechanisms for
sharing information between user exit functions.
Customizing the PSS System Software
______________________________________________________________________________
WaveWorks PSS, Integration Guide, 1.10 Page 106
© 2000, Symbol Technologies, Inc. February 1, 2000
PSS base code is linked with Microsoft's Multithreaded DLL runtime library, so integrators must
link a custom user exit DLL using that same library. Otherwise runtime errors will occur with
the CpssMsgLog and CSymStatementPool classes that are used in the stub User Exits.
9.4.2 Return and Message Codes
The following return codes are used by the standard PSS software to determine how to proceed
after the User Exit routine has returned to the calling routine. The name and numeric value must
also be defined in database table PSS_TEXT if this name is to be used as the msgcode field for
writing a message to the PSS System Log.
UE_CONTINUE Indicates PSS should continue with normal processing
UE_DONE Indicates the User Exit has performed all necessary processing and PSS should skip its
normal processing.
Note: A UE_DONE returned by a "PreProcess" function will cause PSS to skip the call
for the "PostProcess")
UE_ERROR Indicates the User Exit was unable to process sucessfully PSS processing will write a
message to the log and continue processing in the same manner as if a UE_CONTINUE
was returned unless documented otherwise for the individual User Exit.
9.4.3 Using the CPssMsgLog Class
All of the PSS software uses a C++ class named CPssMsgLog for writing operational status and
error messages to the PSS System Log. Customized User Exits should make use of this class to
keep system logging consistent for troubleshooting purposes. Each line in the PSS System Log
displays the following:
• Date/time the message was written.
• Facility Namea 64-character name which should identify the COM object, NT
Service, or other high-level entity such as "ShoppingTripEndOfTrip" to identify a
transaction type.
• Action Namea 64-character name which represents the specific function which is
logging the message. This should either be the UserExit name or the name of a
specific subfunction used by the UserExit routine.
• Message texta 256-character string that contains the information being reported.
The text of these messages is maintained in the PSS_Text database table. The text
in that table can contain tags that represent values which the software supplies to
replace the tag. For instance, the POS file processing replaces a string tag with the
filename of the file being processed and the Unit Management system replaces a
string tag with the MAC address of a terminal that doesn't respond.
Customizing the PSS System Software
______________________________________________________________________________
WaveWorks PSS, Integration Guide, 1.10 Page 107
© 2000, Symbol Technologies, Inc. February 1, 2000
• Severityrepresents the severity of the condition being logged. A System setting
value, subname "Trace_Level", is maintained for the Facilities that log messages.
If the message severity value is less than the severity value specified in the
LogMessage call, the message is not written to the log. For instance, if the
Trace_Level is set to 2 (Warning), then messages with a severity value 1
(Informational) are not written to the log, but messages logged with the severity 3
(Error) are written to the log. The value 2 is the default Trace_Level value set for
most facilities by the PSS installation scripts. The Trace_Level values can be
modified using the System Settings Page on the PSS Administration terminal.
The allowable values for severity which can be specified in a LogMessage call are:
• PML_DEBUGlevel 0, used to log messages helpful in debugging code during
development. Examples are logging the values of parameters used or calculated by
software. The default Trace_Level settings suppress these messages.
• PML_INFOlevel 1, informational messages that typically log the operational status of
software. Examples are positive status about the completion of an operation (Function
XYX completed successfully). These are messages that would not normally be enabled in
the System Log because there would be many such messages cluttering the log and they
would obscure more severe messages. If there were a perceived system problem, then
troubleshooting procedures might suggest setting the Trace_Level to 1 so these messages
would be written to the log and could be reviewed to see if software functions were being
performed as expected.
• PML_WARNINGlevel 2, Error conditions which the PSS software is readily able to
recover from. The default Trace_Level settings write these messages to the log. These
messages may or may not indicate a system malfunction.
• PML_ERRORlevel 3, Error conditions that indicate a system malfunction that is causing
operational errors. The default Trace_Level settings write these messages to the log.
Some corrective action will normally need to be taken to reinstate proper system operation.
• PML_FATALlevel 4, Critical Error conditions that stop the operation of PSS system
components. These messages typically accompany other indications such as turning the
PSS Administration terminal's Main Menu traffic light red and the disabling of the ability
of PSS to perform shopping activities.
• PML_ALWAYSlevel 10, Status messages that do not indicate error conditions, but
which should always be written to the System Log. Examples are startup and shutdown
messages logged by PSS services or activation messages logged by scheduled tasks.
See the PssMsgLog.h header file for more programming details.

9.5 Available User Exit Functions
Following is a complete list of the User Exit routines as called by the standard PSS Software,
along with a brief description of the intended purpose of the User Exit routine and a description
of how the base PSS software reacts to the return code received from the User Exit. For the most
recent information on functionality and more details about specific arguments passed to the User
Exit routines, review the header file PssUserExits.h.
9.5.1 UE_PreProcessItemFile
This function is called before processing of Item Record File is performed. It receives the file
path of the item file as an argument.
The base PSS software handles the following return codes from the User Exit as follows:
UE_CONTINUE: PSS processes the item record file as if no Pre-Processing was performed
UE_DONE: PSS performs no Item record file processing
UE_ERROR: PSS logs an error then proceeds as with UE_DONE
9.5.2 UE_PreProcessItemRecord
This function is called after an item record is read from the file, but before PSS performs any
processing of the record. It is anticipated that this UE function will be used to either replace all
PSS Item record processing or to alter the input buffer that PSS processes.
The base PSS software handles the following return codes from the User Exit as follows:
UE_CONTINUE: PSS processes the item record as if no Pre-Processing was performed, validating the
item record and loading it into the PSS database.
UE_DONE: PSS performs no record processing and proceeds to read the next record
UE_ERROR: PSS logs an error then proceeds as with UE_DONE
Note: If a UE_DONE is returned, the POS_Item_Flag field of the record in table PSS_Item
must have been updated to "Y" or the record for that item will be deleted from the database by
PSS end of file processing.

10. System Administration Interface
The System Administration Interface provides browser-based access into the data contained in
the system database, as well as various system control functions. The purpose is to allow store
personnel to manage the system, obtain information, and provide updates to the information.
The available data concerns almost every facet of the system, including:
• Customer current and historical data
• Messaging
• Hardware configuration
• Item data and marketing
• Reports
• System Status
• System Configuration
10.1 Configuring the Browser Software
Install the desired browser software on the Service Terminal. The recommended browser
software packages are:
• Netscape Navigator (Netscape Communications Corporation), v4.08 or greater
• Microsoft Internet Explorer (Microsoft Corporation), v5.0 or greater
Create a shortcut icon on the desktop for the browser, for ease of access by store personnel.
Set the PSS Administration Main Menu screen as the “HOME” page of your browser software.
The home page will then be automatically displayed when the browser software is started. The
path to the main menu is: http://localhost/pssinterface/administer.asp, where localhost is either
the literal text string ‘localhost’ or the name or IP address of the Service Terminal computer
itself.
10.2 Establish User Accounts on the Service Terminal
A browser screen is provided to create employees accounts and control employee access to the
Service Terminal. To access the screen, from the PSS Main Menu, select System / Settings /
Configuration / Administration Users. The Administration Users screen, which is ordered
alphabetically by user names, appears. Related user data includes:
• Full name of the user.
System Administration Interface
______________________________________________________________________________
WaveWorks PSS, Integration Guide, 1.10 Page 115
© 2000, Symbol Technologies, Inc. February 1, 2000
• Valid starting and expiration dates and times for user’s access to the PSS.
• Privilege levelsecurity level to which the user is assigned. This controls the functions
that are displayed (as described below). These levels, from highest to lowest, are:
- Administratorhas the same functions as all others, plus additional functions.
- Technicianhas the same functions as Manager and Customer Service, plus some
additional functions.
- Managerhas the same functions as Customer Service, plus some additional functions.
- Customer Servicehas the fewest functions.
• The language spoken or preferred by this administrative user. If a particular text string
does not exist for the language preferred by the user, the store language, or, as a last resort,
US English will be used.
• All data concerning user accounts is stored in the PSS_Admin_User database table.
10.3 Understanding User Access to Administrative Pages and
Actions
For each security level (Administrator, Technician, Manager, Customer Service) of user
accounts, there is default access established to Administrative Pages (which are browser pages)
and to Administrative Page Actions (which are distinct tasks contained on browser pages). This
allows for a high degree of flexibility in controlling user access.
Two browser screens are provided to maintain these Administrative Pages and Page Actions.
To access the Administrative Pages screen, from the PSS Main Menu, select System / Settings /
Configuration / Admin Pages. The Administration Pages screen, which is ordered alphabetically
by page name, is displayed. Related data includes:
• Page description
• Minimum user privilege level
• Whether or not authenticated login is required
• Whether or not the page is disabled
All data concerning administrative pages is stored in the PSS_Admin_Page database table.
To access the Administrative Actions screen, from the PSS Main Menu, select System / Settings
/ Configuration / Admin Actions. The Administration Actions screen is displayed. Related data
includes:
• Description of the action
• Minimum user privilege level
• Whether or not the action is disabled
System Administration Interface
______________________________________________________________________________
WaveWorks PSS, Integration Guide, 1.10 Page 116
© 2000, Symbol Technologies, Inc. February 1, 2000
All data concerning administrative actions is stored in the PSS_Admin_Action database table.
The default permission settings for pages and page actions should be sufficient for providing
appropriate system access to each level of user. However, differing customer requirements may
make modifications to these default settings necessary.
In general, raising the authentication levels to make features available to fewer users is not a
problem, but care should be taken to make sure that each level of user has access to all of the
features necessary for their use of the system. For example, a customer service user should
always have access to customer-related functions—not only to the obvious lookupuser.asp (Find
Customer) and registeruser.asp (Add Customer) pages--but also to the support pages for
customer functions, such as issueterminal.asp (Issue Terminal) and unabletoissue.asp (Unable to
Issue a Terminal). The same rule applies for privileges on actions.
Care be taken that the combinations make sense; for example, requiring higher privilege levels
for viewing than for modifying a customer name would be largely ineffective.
Lowering the authentication levels to make features available to more users should be done with
extreme caution. In some cases, lowering authentication levels can, in effect, remove all security
from the system (i.e., lowering the privileges on the Administrative Pages or Page Actions
pages). Lowering the authentication levels on particular actions could also cause problems. For
example, lowering the Modify Customer Rescan Level or Modify Gold Customer action could
allow any customer service user to set customers levels so that they would never be rescanned,
regardless of previous rescan results. The Suspend / Unsuspend Customer actions could also be
abused similarly.
10.4 Changing Screen Text on the Service Terminal
The text that appears on the Service Terminal is stored in the PSS_Text database table. The
Service Terminal uses Text_IDs from 20000 to 30000 and is organized as follows:
Text_ID Contents
20001 - 20099 Menu Titles
Text appearing in the menu buttons in the Service Terminal menu
system
20101 - 20199 Menu Long Names
Text appearing in the pop-up “alternate text” descriptions for
the menu buttons in the Service Terminal menu system
20201 - 20299 Page TitlesText appearing as the page title in the browser title bar
20301 - 20399 Page Short Names
Text appearing as the page title at the top of the page, in the
navigation bar, and in the page buttons in the Service Terminal menu system
20401 - 20499 Page Descriptions
Text appearing as pop-up “alternate text” descriptions for the
page buttons in the Service Terminal menu system.
20501 - 20599 Action Descriptions
Text appearing as action Descriptions on the Admin Actions
page
20601-20699 Page State TitlesText appearing as the page title in the browser title bar for pages
with multiple “states,” for example, the Add Customer page also performs Modify
Customer activities.
System Administration Interface
______________________________________________________________________________
WaveWorks PSS, Integration Guide, 1.10 Page 117
© 2000, Symbol Technologies, Inc. February 1, 2000
20701 - 20799 Page State Short Names
Text appearing as the page title at the top of the page, in
the navigation bar, and in the page buttons in the Service Terminal menu system
for pages with multiple “states.”
20801 - 20899 Page State DescriptionsText appearing as pop-up “alternate text”descriptions for
the page buttons in the Service Terminal menu system for pages with multiple
“states.”
20901 - 20999 Miscellaneous Menu Text
Text used for particular purposes in the Service
Terminal menu system, for example, the text for logging in and out of the system is
stored here.
21000 - 21099 Miscellaneous Text
Text used for particular purposes throughout the Service
Terminal, for example, the strings for months of the year, or days of the week are
stored here.
21101 - 29999 Page Text
Text for each page in the Service Terminal is stored in this region.
The formula for determining the range for a particular page is (21000 + (Current
Page ID x 100)). Page Ids are all stored in the PSS_Admin_Page table. For
example, page 51 is the Admin Actions page, and its text region is 21000 + (51 x
100) = 26100 (to 26199).
10.4.1 Service Terminal System Settings
The behavior of the Service Terminal can also be modified by a collection of system settings,
with Name “SVCTERMINAL.” These settings control:
• The use of various features or fields that may not be used at every installation for display
or in calculating the system status
• The dimensions of hand-held terminal messaging displays
• Service Terminal hardware settings
• The length of time before user login sessions time out
• Transactions for resetting system software components
The PSSSysInit settings provide the transactions for resetting system COM Objects through
WaveWorks. On the System Settings administrative page, there is a link at the bottom of the
page, Re-Initialize PSS System. When this link is selected, a CMS message “PSS998” is sent to
all standalone executables, such as services, subscribed as “PSSSYS.” In addition, all system
settings with Name “SVCTERMINAL” and Subname “PSSSysInitX” (where X is a custom
string appended to the Subname) are traversed. The value is sent as a multicasted transaction,
that is, sent to all instances of a COM object that handles that particular transaction.
Additional transactions may be added to the system by adding system settings with Name
“SVCTERMINAL,” Subname “PSSSysInitXXX,” where XXX is a custom string appended to
the Subname. For custom transactions, it is recommended that letters be used for the custom
string (e.g., A - Z) to avoid conflicting with future additions to the PSS system, which will use
numbers.

Tx ID: PST105
Class: PssDbCleanupCOM
Method: PerformDBCleanup
Description: PerformDBCleanup performs a number of operations to reduce the number of
rows in various database tables, thus improving system performance and eliminating obsolete or
unnecessary data. Its operation is configurable based on entries in the system settings with name
“PSSDBCleanup.” The configuration is read when the COM object is initialized, and since this
routine typically runs only once per night, it should happen each time that PerformDBCleanup is
run.
The first step is the cleaning of the PSS_Message_Log table. All records in the table that are
older than the configured number of hours and are not required for system reporting are deleted
from the table. Currently, the only message log entries used for system reporting are those with
facility ‘Unit Management’ and action 'TerminalCount', 'OperationalCount', 'TerminalIssued', or
'TerminalReturned'. Actions required for reporting are kept for 13 months, which is the current
limit for the system reports.
Next, the PSS_POS_Status table is processed. All records with a Start_Time or Detection_Time
older than the configured number of hours for each type is deleted from the table, except for the
records with Item_Name ‘POSControllerName’, for which there is always only one record for
each POS controller in use.
Finally, the shopping trip data is processed. This includes both the current shopping list data
from PSS_Shopping_List, and the historical data from both PSS_Shopping_History_List and
PSS_Shopping_Incomplete_List.
For current shopping lists, any shopping list data with a Time_Started older than the configured
number of hours is deleted. Shopping list data includes all associated items
(PSS_Shopping_Item), activities (PSS_Shopping_Activity), tax data (PSS_Shopping_Tax),
marketing data (PSS_Marketing_Sent), exception items (PSS_Unknown_Item), and quick order
list (PSS_Order_List) and item (PSS_Order_List_Item) data. Exception item data for which
barcode was scanned, terminal used, and time of scan is kept in the PSS_Unknown_Item table,
but the link to the customer shopping list is removed.
Parameters:
Input:
none

11. Specific Features
11.1 Multiple Language Support
Support for multiple languages is provided for all screens displayed on the hand held terminals,
all screens displayed on the entrance units, and all PSS log messages. All language sensitive text
is held in the PSS_Text table in the database. The keys for each text string are a Text ID and a
Language ID. Based on the key, the string in the proper language is returned.
The Active Server Pages used for the System Administration screens will need to be rewritten in
the store’s preferred language, if the store’s preferred language is other than English.
11.2 Pricing Methods
See Appendix C.
11.3 Currency Conversions
The forumla for converting currencies is as follows:
Currency Y amount = (Exchange_Rate Y / Exchange_Rate X) * Currency X amount
Where each Exchange_Rate value is read from the PSS_Currency table for the particular
currencies in use. Exchange_Rates for all currencies should be in the same base amount, that is,
a single currency should be chosen as having an exchange rate of 1, and all other currencies
should be entered as values relative to that currency. For example, if US Dollars is chosen as
having an Exchange_Rate of 1, Canadian Dollars may have an Exchange_Rate of 1.47. To
convert 2 Canadian Dollars to US Dollars, the formula is therefore:
US Dollar amount = (1 / 1.47) * 2 = 1.36 US Dollars
11.4 Control Ticket Printing
The text that appears on the PSS shopping trip transaction ticket is stored in the PSS_Text table
in the PSS database. The Service Terminal uses Text_IDs starting at 7000.
The contents of the transaction ticket are configurable based on system settings in
PSS_System_Setting with a name of “TRANSTICKET.”
There is also a printing user exit, UE_PrintReceipt, which is called after the Transaction Ticket
COM object creates a template print file. The template print file is sent to the Printer Service to
be interpreted to literal print commands for a particular printer.

Appendix C Price Calculation Algorithms
This appendix describes how price calculations are performed.
A price is calculated for every item scanned during a shopping trip. Each item has an associated
pricing method. The following item characteristics are used to determine how to calculate its
price.
• Pricing methodThe pricing method helps to determine the equation used to calculate the
price of an item.
• Mix and match numberThe mix and match number is used to indicate whether or not an
item can be part of a pricing deal that includes other items.
• DepartmentThe department helps to determine which mix and match pricing deal to apply
to an item.
The following item characteristics are used as inputs to price calculation equations.
• Deal quantity / Deal weightA deal quantity must never be negative. A deal quantity of
zero is treated as a one.
• Deal priceThe meaning of the deal price associated with an item depends on the pricing
method associated with that item. A deal price is always equal to or greater than zero.
• Unit priceThe unit price helps to determine which mix and match pricing deal to apply to
an item. The unit price is always equal to or greater than zero.
C.1 Pricing Methods
The following pricing methods are used by the PSS system:
• Split Package Pricing
• Unit Pricing
• Base Plus One Pricing
• Group Threshold Pricing
• Group Adjusted Pricing
• Unit Adjusted Pricing
Below is a description of each of the pricing methods used on the PSS system. Included in each
description is an example calculation. All pricing methods described as a group pricing method
require a price rounding method. All calculated prices in the examples are always rounded up.
Appendix D POS Interface File Descriptions Overview
WaveWorks PSS, Integration Guide, 1.10 Page 159
© 2000, Symbol Technologies, Inc. February 1, 2000
C.2 Split Package Pricing
The Split Package Pricing Method is a group pricing method based on a deal price and a deal
quantity or a deal weight.
The price of an item is calculated using one of the following equations:
( Purchase Quantity * Deal Price )
Item Price = -------------------------------------
Deal Quantity
OR
( Purchase Weight * Deal Price )
Item Price = ----------------------------------
Deal Weight
Split Package Pricing Example
An item costs $1.00 for a quantity of 5. The customer purchases a quantity of 3 of the item.
Item Price=(3*1.00 )/5 = $0.60
A weight-based item costs $5.00 for a weight of 2 lbs. The customer purchases 3 lbs. of the item.
Item Price = ( 3 * 5.00 )/2 = $7.50
C.3 Unit Pricing
The Unit Pricing Method is a simplified version of the Split Package Pricing Method. The price
used in the equation is the unit price instead of the deal price and the deal quantity / deal weight is
equal to 1 or 0.
The price of an item is calculated using one of the following equations:
Item Price = Purchase Quantity * Unit Price
OR

Item Price = Purchase Weight * Unit Price
Appendix D POS Interface File Descriptions Overview
WaveWorks PSS, Integration Guide, 1.10 Page 161
© 2000, Symbol Technologies, Inc. February 1, 2000
Unit Pricing Example
An item costs $0.49 for a quantity of 1. The customer purchases a quantity of 3 of the item.
Item Price = 3 * $0.49 = $1.47
A weighted item costs $1.29 for a weight of 1 lb. The customer purchases 3 lbs. of the item.
Item Price = 3 * $1.29 = $3.87
C.4 Base Plus One Pricing
The Base Plus One Pricing Method is a group pricing method based on a deal price and a deal
quantity. This pricing method accumulates previously sold items of the same type or group.
Every time an item needs to be included in the group the total price is recalculated for the new
purchase quantity. The price of the added item is adjusted to reflect the new total for the group.
The price of the added item is calculated using the following equations.
(Purchase Quantity * Deal Price)
New Total Price = --------------------------------
Deal Quantity
Item Price = New Total Price – Previous Total Price
Base Plus One Pricing Example
Items of the same type or group are sold at five for $0.47. The items are added at different times
during the shopping trip.
Item Number 1 added to shopping list.
New Total Price=(1*$0.47 )/5 = $0.10
Item Price = $0.10 – $0.00 = $0.10
Item Number 2 added to shopping list.
New Total Price=(2*$0.47 )/5 = $0.19
Item Price = $0.19 – $0.10 = $0.09
Item Number 3 added to shopping list.
Appendix D POS Interface File Descriptions Overview
WaveWorks PSS, Integration Guide, 1.10 Page 162
© 2000, Symbol Technologies, Inc. February 1, 2000
New Total Price=(3*$0.47 )/5 = $0.29
Item Price = $0.29 – $0.19 = $0.10
Item Number 4 added to shopping list.
New Total Price=(4*$0.47 )/5 = $0.38
Item Price = $0.38 – $0.29 = $0.09
Item Number 5 added to shopping list.
New Total Price=(5*$0.47 )/5 = $0.47
Item Price = $0.47 – $0.38 = $0.09
Item Number 6 added to shopping list.
New Total Price=(6*$0.47 )/5 = $0.57
Item Price = $0.57 – $0.47 = $0.10
C.5 Group Threshold Pricing
The Group Threshold Pricing Method is a group pricing method based on a unit price, a deal price,
and a deal quantity. This pricing method accumulates previously sold items of the same type or
group. The unit price is applied to items added to a group until its deal quantity is reached. When
the deal quantity is reached the total price is calculated using the deal price and the deal quantity.
The price of the threshold item is adjusted to reflect the total price for the group. Adding
additional items to the group begins a new deal.
The prices of the items sold before reaching the deal quantity are calculated using the following
equations:
Item Price = Unit Price
Purchase Quantity
Total Price = ------------------ * Deal Price +
Deal Quantity
((Purchase Quantity % Deal Quantity) * Unit Price)
The price of the threshold item is calculated using the following equations:
(Purchase Quantity * Deal Price)
Total Price = --------------------------------

Group Threshold Pricing Example
Items of the same type or group are sold at five for $0.47. The unit price of the items in the group
is $0.10. The items are added at different times during the shopping trip.
Item Number 1 added to shopping list.
Item Price = $0.10
Total Price = ((1/5) * 0.47) + ((1 % 5) * $0.10) = $0.10
Item Number 2 added to shopping list.
Item Price = $0.10
Total Price = ((2/5) * 0.47) + ((2 % 5) * $0.10) = $0.20
Item Number 3 added to shopping list.
Item Price = $0.10
Total Price = ((3/5) * 0.47) + ((3 % 5) * $0.10) = $0.30
Item Number 4 added to shopping list.
Item Price = $0.10
Total Price = ((4/5) * 0.47) + ((4 % 5) * $0.10) = $0.40
Item Number 5 added to shopping list.
Total Price=(5*$0.47 )/5 = $0.47
Item Price = $0.47 – $0.40 = $0.07
Item Number 6 added to shopping list.
Item Price = $0.10
Total Price = ((6/5) * 0.47) + ((6 % 5) * $0.10) = $0.57
Item Number 7 added to shopping list.
Item Price = $0.10
Total Price = ((7/5) * 0.47) + ((7 % 5) * $0.10) = $0.67
Item Number 8 added to shopping list.

Item Price = $0.10 ( Unit Price )
Total Price = ((9/5) * 0.47) + ((9 % 5) * $0.10) = $0.87
Item Number 10 added to shopping list.
Total Price=(10*$0.47 )/5 = $0.94
Item Price = $0.94 – $0.87 = $0.07
C.6 Group Adjusted Pricing
The Group Adjusted Pricing Method is a group pricing method based on a unit price, a deal price
and a deal quantity. This pricing method accumulates previously sold items of the same type or
group. The deal price for this pricing method is often referred to as the reduced price. The deal
price is treated as an item price rather than a package price.
The unit price is applied to items in a group until the deal quantity is reached. The price of the
threshold item is calculated to bring the total group cost equal to the number of items sold at the
deal price. All items added to the group after the threshold item are sold at the deal price.
The prices of the items sold before the threshold item are calculated using the following equations:
Item Price = Unit Price
Total Price = Purchase Quantity * Unit Price
The price of the threshold item is calculated using the following equations:
Total Price = Purchase Quantity * Deal Price
Item Price = Total Price – Previous Deal Price
The prices of all items added after the threshold item are calculated using the following equations:
Item Price = Deal Price
Total Price = Purchase Quantity * Deal Price
Appendix D POS Interface File Descriptions Overview

© 2000, Symbol Technologies, Inc. February 1, 2000
Group Adjusted Threshold Pricing Example
Items of the same type or group are sold at a unit price of $0.10. A special price of $0.08 is
activated when 3 items are purchased.
Item Number 1 added to shopping list.
Item Price = $0.10
Total Price=1*$0.10 = $0.10
Item Number 2 added to shopping list.
Item Price = $0.10
Total Price=2*$0.10 = $0.20
Item Number 3 added to shopping list.
Total Price=3*$0.08 = $0.24
Item Price = $0.24 - $0.20 = $0.04
Item Number 4 added to shopping list.
Item Price = $0.08
Total Price=4*$0.08 = $0.32
Item Number 5 added to shopping list.
Item Price = $0.08
Total Price=5*$0.08 = $0.40
C.7 Unit Adjusted Pricing
The Unit Adjusted Pricing Method is a group pricing method based on a unit price, a deal price and
a deal quantity. This pricing method accumulates previously sold items of the same type or group.
The deal price for this pricing method is often referred to as the reduced price. The deal price is
treated as an item price rather than a package price. This pricing method can be used to control the
distribution of free merchandise.
The deal price is applied to items in a group until the deal quantity is exceeded. All items added to
the group after the threshold item are sold at the unit price.
The prices of the items sold before the deal quantity is exceeded are calculated using the following
equations:
Item Price = Deal Price
Appendix D POS Interface File Descriptions Overview
WaveWorks PSS, Integration Guide, 1.10 Page 168
© 2000, Symbol Technologies, Inc. February 1, 2000
Total Price = Purchase Quantity * Deal Price
The prices of all items added after the threshold item are calculated using the following equations:
Item Price = Unit Price
Total Price = ( Deal Quantity * Deal Price ) +
( ( Purchase Quantity – Deal Quantity ) * Unit
Price )
Unit Adjusted Threshold Pricing Example 1
Items of the same type or group are sold at a unit price of $0.25. The items are on special for
$0.20 with a limit of 3 per customer.
Item Number 1 added to shopping list.
Item Price = $0.20
Total Price=1*$0.20 = $0.20
Item Number 2 added to shopping list.
Item Price = $0.20
Total Price=2*$0.20 = $0.40
Item Number 3 added to shopping list.
Item Price = $0.20
Total Price=3*$0.20 = $0.60
Item Number 4 added to shopping list.
Item Price = $0.25
Total Price=(3*$0.20)+((4–3)*$0.25 ) = $0.85
Item Number 5 added to shopping list.
Item Price = $0.25

Unit Adjusted Threshold Pricing Example 2
Items of the same type or group are sold at a unit price of $0.20. One item of the group per
shopping trip is free.
Item Number 1 added to shopping list.
Item Price = $0.00
Total Price=1*$0.00 = $0.00
Item Number 2 added to shopping list.
Item Price = $0.20
Total Price=(1*$0.00)+((2–1)*$0.20 ) = $0.20
Item Number 3 added to shopping list.
Item Price = $0.20
Total Price=(1*$0.00)+((3–1)*$0.20 ) = $0.40
C.8 Mix and Match Groupings
Mix and match is the name for the technique that lets a customer purchase items within the same
group or pricing deal while mixing items but matching the unit price. Each item eligible for a mix
and match pricing deal will have the same group number in the item record of each item in the
group. Mixed items in a pricing deal must have the same unit price and the same department.
C.9 Pricing Method Application Rules
The following application rules apply to the pricing methods.
• All weight items use either the Unit Pricing Method or the Split Package Pricing Method.
• All items with price embedded barcodes use the Unit Pricing Method. The embedded price
becomes the unit price and the purchase quantity is treated as a one.
• If an item is assigned to use the Base Plus One Pricing Method but its deal price is evenly
divisible by its deal quantity, its price is calculated using the Split Package Pricing Method.
• If an item is assigned to use the Group Threshold Pricing Method and its deal quantity is 1,
its price is calculated using the Unit Pricing Method.
• Only the Group Adjusted Pricing Method and the Unit Adjusted Pricing Method allow an
item to be given away using a deal price of zero and a deal quantity of one.
• Mix and match groupings can be used in the Unit Pricing Method, the Base Plus One Pricing
Method, the Group Threshold Pricing Method, the Group Adjusted Pricing Method, and the
Unit Adjusted Pricing Method.

Record Length Fixed for each record type (length depends on expansion area configuration
Number of Records Variable, one header record, plus one record for each item purchased.
This file consists of a transaction information and item information. The Header Record has details of the
customer number, the selfscan transaction ‘barcode’, the number of items in the selfscan transaction and
whether the POS operator re-scanned the items. Following the header record are the item records. Each item
record represents one article processed at the POS and includes the item code, price and a number of
implementation specific ‘flags’. The file is in ASCII format with each record being terminated by a carriage
return/line feed delimiting character pair.
