Chapter 1—Introduction

What’s in this Manual

®

This manual provides instructions for installation and operation of the IEE ScanVue5

Price Verifier. Chapter 1 introduces the ScanVue5

® hardware and describes its basic functions and features. The following chapters describe how to physically install the unit in its intended location, configure and set up your specific network and interface

ScanVue5

® to a back office server through its Application Programming Interface (API).

The current software version number is displayed on the first status screen appearing after powering up the unit (if properly configured). A barcode is available to display the status screen directly (Appendix A); the host can query the unit for the same information.

Software updates, the entire CD-ROM SDK contents and later versions of this manual are available on IEE’s FTP web server at www.ieeinc.com

.

Be aware that ScanVue5 models running V5.x software cannot be upgraded to V6.x

software as the hardware platform is different. The same server application will work with both software versions with the exception that some features supported in V6.x may not be supported in V5.x.

Revision R of this manual is current with software version V6.20. Certain features may not be supported in earlier software versions or hardware platforms. User Manuals specific to software versions and hardware platforms can be obtained on request.

ScanVue

®

Models

The ScanVue

® can be configured as a kiosk or as a price verifier. In its kiosk form it may be sold with touchscreen, printer, keypad, magnetic stripe reader, barcode reader and

LCD display. Each input device is optional so that in its price verifier form it consists of a number of different models that appear externally identical but have different features.

Model TA05–2XX is a hard–wired only unit with a ¼ VGA color AMLCD display. Models

TA05–1X and TA05–3X have an optional 11Mbps (IEEE 802.11b) wireless–network interface installed, while Model TV42–XX has a 4x20 fixed width character vacuum fluorescent (VF) display with optional wireless–network. Each of these models have an optional bank of 4 switches on the front panel. These switches have no pre–assigned functions but when depressed send the switch number and time–open and –close events to the host computer. Models with a co-located Citizen printer (uses the same power supply for the printer and ScanVue5 and shares a dual mounting bracket), keypads and a magnetic stripe reader are available. AMLCD models also have a 16x12 digital touch screen available that operates in a similar way to the switches, sending the

X,Y co-ordinate of the location on the screen when touched.

All these models are transparent to the API—that is, they may be interchanged without having to modify host computer software or your network. A sister product, ShopVue5

® which uses the same display in a slim housing without the scanner can also co–exist on the same network. It operates from the same software and can be used in locations where only the advertising is needed such as a checkout stand.

ScanVue5

Description

ScanVue5

® is a multi–function price verifier designed to allow a retail store customer to check the price of any UPC barcoded product without having to leave the aisle or shelf area. As well as displaying the price and description of scanned items, ScanVue5

® color graphics LCD can display specials or promotions, manufacturers co-op advertising, check gift card balances or provide other customer information. Thus, as well as performing a service to the customer, ScanVue5

® can directly generate advertising revenue for the store. The advertising display can be sequential still images (slides), short animation clips, text, graphics or a mix of all these types of display. The contemporary housing design merges well with almost any store décor and custom color combinations are available if the units are ordered in sufficient quantities. A number of different options for mounting the ScanVue5

® unit are available.

The ScanVue5

® price verifier consists of a barcode scanner located in the underside of the housing, a 5.7”, ¼ VGA color graphics LCD display or [optional] 4x20 vacuum fluorescent display, 4 [optional] front panel push button switches that can be used to perform any function required by the end user, and an embedded microprocessor–based controller running an application program that drives the scanner, the push buttons and the graphics display and manages the operation of the unit. Communications between

ScanVue5

® and the host computer can be hardwired 10baseT Ethernet or wireless

802.11x. An external RS232 serial port is available via an optional Y cable and supports a hand scanner a coupon printer or any other serial device. The electronics package is completely contained in a high impact ABS injection molded case. A metal mounting bracket is shipped with the unit. The unit meets most worldwide regulatory safety and

EMC standards including UL1950, CSA22.2, TUV, FCC, CDRH, NOM and CE.

A new feature of ScanVue5’s software is the ability to run a “protocol converter”. This means that an existing price-verifier application running on a network server for another type of unit can be converted at the ScanVue5 side to run without a rewrite of the host application code. Contact factory for quote for a custom protocol converter.

Demonstration Mode

Demo mode provides a functional demonstration of Scanvue in a ‘stand alone’ mode without the need to connect to a network. In demo mode, an internal server and item lookup file will display graphic item information when the appropriate item barcode is scanned. The demo program uses multiple level images to show how additional item information can be displayed—for instance, a food item can display a recipe on the second level.

Demo mode is entered by scanning Demo Mode and then the Save and Reset barcodes. The unit will stay in this mode until barcoded back to its normal mode. Demo item barcodes are available in the documentation section of the CD-ROM.

Technical Knowledge Required

Installation

T

he installation of ScanVue5

® is a reasonably easy process for a person familiar with installing and maintaining local area networks (LAN’s). Although we have provided various software tools to help with the network setup, this manual is not intended to be a


ScanVue5

®

Mini Kiosk

User Manual

M37574–01T


training guide for novice network installers. It is assumed the installation will be done by a person having a sufficient level of technical expertise with LAN hardware and software to understand the content of this manual and complete the job with minimal outside help.

A system or network administrator is capable of performing the installation with ease.

IEE can provide additional technical assistance in getting the system running, if required.

Operation

Once ScanVue5

® units are installed and configured, any person familiar with a PC and able to write simple macros or script files will be able to create graphics–based presentations (called slideshows) using Microsoft WordPad ™ or a similar text editor.

Image files can be obtained from various sources—downloaded from a website, scanned in from a digital scanner or transferred from a digital camera. Familiarity with a graphics editor program would be helpful in preparing the images for slideshow presentations.

Application Program Interface (API)

An API that provides the interface between ScanVue5

® and the network host computer application is described in detail in Chapter 4. The API is written in ANSI “C” and can be integrated with any ANSI ‘C’ compiler. The database application and its interface to

ScanVue5

® will generally reside on the network host computer (sometimes called the network server). Numerous different hardware or software platforms may be used as long as TCP/IP is the network transport–protocol. Typical platforms are AS400, VAX,

Wintel hardware running Windows NT/2000/ME/XP, Unix, VMS, Oracle, SQL…

The database application program is responsible for receiving a request from a scanner, retrieving the price and description from the database, and returning that data to the unit that initiated the request. The development and maintenance of any host computer based application program required to access a product–information database is the sole responsibility of the end user or their system integrator. IEE provides an SDK including some license free “C” source code to assist the end user in writing applications on their host machine.

M37574–01T


Wall Mounted

The wall mount bracket is provided as a standard item shipped with the unit (Appendix F for actual dimensions). The wall bracket can be mounted on any type of flat vertical surface using the 6 mounting bosses with holes. The bracket can also be mounted by a special double-sided tape to a glass column or wall. Mounting hardware is not provided as the material used in the vertical wall can vary depending on the location chosen and either wood screws or toggle bolts or equivalent are recommended. Do not use wood screws or sheet metal screws in drywall—they will not hold the weight of the unit.

Note: contact factory for recommendation of double sided tape—do not use the kind you might find in the local drug store or hardware store.

The wall mount bracket is removed from the rear of the unit, sliding it up and off of the 4 vertical tongues, and mounted to the wall, column or endcap. A hole is provided in the bracket for bringing the power and/or network connection through from the wall or column.

Locking screws (x2)

Fig 1—Wall Mount Bracket

The ScanVue5 unit is pushed close to the wall about 1” above the bracket tongues.

Push it downward until the 4 tongues mate securely with their counterpart slots in the rear of the housing. Tighten the 2 locking screws through the slots in the housing until snug—this will prevent anybody from removing the unit from its mount.

User Manual

M37574–01T


A double-wide bracket that places the label printer directly on the left side of Scanvue is provided when the co-located printer option is purchased. The printer and Scanvue are mounted side by side on a sub-panel pre-wired for a single power supply and ready to be mounted to a wall almost exactly like a single Scanvue.

Stand Mount

An optional kit can be purchased (IEE P/N xxxxx-01) for mounting the unit on a desktop or counter top. The stand comes with assembly instructions and a special VESA mount bracket to replace the wall mount bracket. Once mounted on the stand the unit can be swiveled left and right, up and down and raised or lowered to get the best possible position for the scanner.

Wiring the Ethernet Model

Once the ScanVue5

® unit is mounted in place there are 2 cables (1 cable only if 802.3af

IEEE PoE option is selected) that must be connected before it can be operated. For aesthetic reasons we suggest the AC and network outlets are mounted close to (or in) the ceiling or close to the floor. The two cables may also be routed inside the wall or column and plug into the AC and network connections in the ceiling. This is the recommended method and provides the cleanest installation.

1. Plug the RJ45 cable Ethernet cable connected to the hub or switch on your LAN into the RJ45 connector in the rear of the ScanVue5

® unit (Figure 6).

2. Connect the 8–pin DIN extension cord and the DIN connector coming from the

ScanVue5

® unit. Line up the arrows on the two connectors and the pins will be aligned for insertion. On some models, the 8–pin DIN connector is mounted on a PC board that is accessible from the back of the unit underneath the mounting bracket

(Figure 6). The RJ45 Ethernet connector is also mounted on this PC board

3. Plug the other end of the DIN extension cord into the DIN connector on the power supply.

4. Plug the power supply into a grounded electrical outlet—the ScanVue5

Wiring the RF Wireless Model

If you purchased the wireless network option, the 802.11b Wi-Fi card will already be installed and tested at the factory. The installation is the same as shown above for a hardwired unit, except no RJ45 cable is needed for wireless operation.

Installation of RF communication links requires special expertise and is part of your site network and as such the manufacturer of the access point (and your network staff) should be the first line of technical support. Most of the manufacturers of access points have extensive technical documentation on performing RF site surveys and correct installation of the units on their web sites.

Entering the ESSID

Each wireless RF access point has a network name (called an ESSID) that consists of up to 32 letters and numbers. When a new ScanVue5

® is shipped from the factory, a default ESSID (INSTALL) is stored in configuration memory. Before it will communicate


ScanVue5

®

Mini Kiosk

User Manual

M37574–01T


with the access point, the ScanVue5

® must have a matching, case sensitive ESSID entered into its memory to replace the default. The ESSID can be entered through the

ScanVue5

® internal barcode reader.

The ESS ID is a barcode label in the following format:

Setting Up a Wireless RF Link

Before installing a new wireless RF data link, it is important to perform an RF site survey to characterize the immediate environment and ensure a reliable system is designed.

The general pointers we indicate below will assist in the initial installation and diagnosis of a link problem, however your first line of technical support is the specialized help available from the manufacturer of the access point or your IS or VAR people doing the installation.

1. Unobstructed line–of–sight is best. If you can, arrange the ScanVue5

® units so there is an unobstructed line–of–sight to the access point. Under these ideal conditions and assuming no interference from other 2.4Ghz sources, you should get up to 150' distance. In a typical office or retail environment 30'–50' is more typical.

2. Mount the access point as high as possible in the line–of–sight. This way the signals should travel above racks, shelving, customers, etc. The human body is 90% water and a good RF signal absorber—this is why cell phones often don’t work well inside buildings and around crowds of other people.

3. Keep reflective surfaces like mirrors and polished stainless steel, and metal objects with sharp points to a minimum and away from the antenna as much as possible.

4. If you are having trouble making a connection, try moving the ScanVue5

® the access point, raising it, or lowering it.

closer to

As the ScanVue5

® unit cannot easily be moved once installed, it is often more convenient to have a portable signal strength meter or an IEEE802.11b RF NIC card in a laptop computer during installs. The NIC driver will have a RSSI graph or will display the signal strength as a percentage depending on the NIC used.

Adding a Hand Scanner

If your ScanVue5

® has software version 4.12 or later, a hand scanner on a cable may be installed in addition to the fixed scanner. The hand scanner is useful for departments that sell large items that cannot easily be read by the fixed scanner. ScanVue5

® works with either scanner transparently—that is, either the fixed scanner or the hand scanner can be used to read an item barcode without having to select which one is being used.

Two manufacturers hand scanners are supported. The Symbol Cobra 1902T scanner requires an optional ScanVue5

® power supply Y cable (IEE P/N 37915–XX, where XX specifies the cable length) that provides the additional RS232 port, serial port 2, for the hand scanner to connect to the ScanVue5

® unit. The Cobra scanner comes with its own wall mount power supply to power the scanner and is required in addition to the power supply that powers the ScanVue5

® unit. The RS232 port is factory pre-set to run the hand scanner. The NCR model 7837 construction and cabling is almost identical to the

Cobra and supported in the same way. The following paragraphs describe setting up the Cobra scanner in detail. A similar setup is required for the NCR scanner.

Wiring and Configuring the Hand Scanner

Once the Cobra scanner is powered up, it must be configured to communicate with

ScanVue5

®

. Section 4 of the Cobra manual contains the barcodes required to perform the setup needed. A manual can be obtained from the Symbol website www.symbol.com

if you don’t have one. Scan the following barcodes in the order shown in Table 1.

Adding a Serial Printer

Software versions 4.16 and later provide support for an external serial printer as well as a hand scanner. The factory default setting for serial port 2 is SCANNER for hand scanner use. If a serial printer is required instead of the scanner, serial port 2 must be changed to OUTPUT or BIDIRECTIONAL using UnitConfig or the modeset commands.

The port may also be disabled by setting it to NONE.

In OUTPUT mode the port parameters are pre-configured for the NCR model 7197

Thermal Receipt Printer. You must also purchase a special Y cable (IEE P/N 38094–XX, where XX specifies the cable length) which breaks out the RS232 port for the printer from the DIN power connector on the rear of Scanvue.

In BIDIRECTIONAL mode the port parameters are pre-configured for the NCR model

K590 Self Service Printer. A Y cable (IEE P/N 38254–XX) is required to connect this printer to ScanVue5

®

. The K590 printer has built-in sensors and diagnostics to detect error conditions that can be reported back to the server through this port.

Other manufacturers serial printers may require a different Y cable or port settings.

Check with the factory before attempting to connect a different printer.

In OUTPUT or BIDIRECTIONAL mode, serial port 2 is a transparent RS232 data port.

ScanVue5

® receives pre-formatted data and control codes from a printer driver resident on the network host, which it passes, unmodified, through serial port 2 to the printer.

Any data returned from the K590 printer in BIDIRECTIONAL mode will be passed up to the network host unmodified. Printer drivers are specific to the printer used and must be provided by the user.

Wiring and Configuring the Serial Port

Use the UnitConfig program or modeset utility to change the serial port configuration to

OUTPUT or BIDIRECTIONAL. If you are using an MS Windows system, open a DOS box and change to the C:\POS directory where modeset is stored and send the 2 following lines. The modeset utility, found on the CD-ROM, must be copied onto your server before these commands can be sent.

C:\POS modeset -iPort2function=OUTPUT {BIDIRECTIONAL} <IP>



C:\POS modeset -c -r <IP>

 where <IP> is the unit’s IP address.

The default serial port 2 settings for OUTPUT are 9600 baud, no parity, 8 data bits, 1 stop bit for and for BIDIRECTIONAL are 19200baud, no parity, 8 data bits, 1 stop bit.

The printer port settings must be set to the same parameters to be able to communicate with it. If you want to run the printer faster or change other parameters, a utility program

PortSet is provided on the CD-ROM for modifying serial port settings.

Connecting To the USB Port

A Type I, USB 1.0 port is available on the rear panel. The USB port does not provide power to the load device. Any standard USB cable will connect this port to a device such as a printer. The LX800 has three sockets, the one closest to the motherboard is

NOT connected electrically; it is there for spacing only.

The USB port is currently used to connect an external Magnetic Stripe Reader (MSR).

See the section under Port3Configuration for more details.

Wiring Precautions

While ScanVue5

® is designed to withstand power and data line surges, spikes and other anomalies in accordance with IEC and CE specifications, it will probably not survive a direct lightning strike. In parts of the USA and worldwide where there is a high likelihood of thunderstorm activity it is good practice to install lightning surge protectors on all power and data lines. ScanVue5

® should be treated like any other network and computer product installed in your facility.

Chapter 3—Installing the Software

Note: it may be easier to follow the step by step Quickstart Guide (available on the CD

ROM in the documentation section).

Before installing the Scanvue5 programs, we highly recommend you install the latest updates or service packs to the operating system you are using. The UnitConfig program especially requires a minimum level of Internet Explorer to be running. On

Windows 98, IE Explorer 6.0 or later and NT or XP require IE Explorer 5.50 or later.

The SetupServer program on the CD–ROM must be run on your Windows network server to create a specific ScanVue5

® directory called POS on your servers’ hard disk, share it and copy the default scanvue.ini file into this directory. ScanVue5

® units look for this file in the POS share when they boot up and will not operate if they can’t find it.

In software versions after and including V5.02, the .ini file will be searched for in all lower case characters. This takes care of servers that are case sensitive (such as Unix)

You should also install UnitConfig the graphical, table oriented version of modeset on the server as it provides the easiest way to change the configuration of a unit on the network (as opposed to scanning barcodes or sending modeset commands). You may also install UnitConfig on a desktop or laptop computer for setting up ScanVue5

® units without a large network complicating it. You will need a network interface card (NIC) installed in your PC and configured properly to communicate with ScanVue5

®

.

UnitConfig version 3.3 or later can also be run directly from the CD-ROM.

For servers that are running other than Windows, sources are provided for the server software. There are also freely available drivers to allow any operating system to act as a Windows–type server.

Important: Scanvue5 V6.2 and later software will detect either scanvue.ini or realscan.ini files. This ensures that an existing NCR installation using realscan.ini will work with new Scanvue units. The shared ScanVue directory and the file must be on the server and the ScanVue5

® unit must be able to find it when they power up. If you want to change the operating modes (or configuration) of a specific unit anytime after the system is up and running, the UnitConfig program is available in the POS directory or on the CD-ROM.

Server Install

When you place the IEE SDK CD–ROM (p/n 37720-01) into a drive, the autoplay feature will open a window with the folders and program icons. If it doesn’t start on its own, click

Windows START button, then Run and enter the CD-ROM drive name (usually d:) in the text box and click OK. The CD will open a new window–double click the IEE folder.

Click on the IEE icon SetupServer and the install program will lead you step by step through the process of creating the POS directory, sharing it, and copying the scanvue.ini file into the directory.

Server install also creates a font directory under POS and loads all the fonts on the CD–

ROM into this directory. ScanVue5

® has one default font programmed into the unit. This is a 16x32 pixel glyph containing all 256 characters of the extended ASCII character set—thus any Latin based language can be supported from this font set.

Unit Configuration

Click on the IEE icon UnitConfig in the root directory SDK CD–ROM window and the

Unit Configuration program will be installed in a subdirectory under POS. This program, which consists entirely of the one screen shown in the section on using Unit

Configuration, implements the specific set of commands and controls defined in the

API for ScanVue5

®

(see Chapter 5). The program is written in Visual Basic

® and the sources and an OCX are provided on the CD–ROM so users can write directly to this program and make or initiate mode changes from their application program

ScanVue5

®

Software Updates

There are 2 basic models of ScanVue5

®

, which utilize different internal processors and operating systems. This is transparent to the customer and the API user and there are no external functional or physical differences between the models with the exception of the process for online software updates. Future software releases will include both update methods for both types of units.

When new software is loaded into ScanVue5

®

, the file image is written into RAM memory. A CRC is calculated and compared with the CRC appended to the file sent from the host. If the two CRC’s are identical, the file has been loaded without errors and it is then written into flash memory. The unit will reboot itself and run the new software.

The model type can be easily identified by the software version number on the status screen when the unit is booted.

Chapter 4—Network Configuration

Introduction

ScanVue5

® is a network–connected device which uses industry standard TCP/IP

® protocols for communication. Connecting ScanVue5 to your network requires the same kind of preparation as connecting a workstation to your network. This manual assumes you know how to obtain the relevant information about your existing network configuration and choose the appropriate configuration parameters so your network will recognize ScanVue5

® devices. We suggest using switches rather than hubs to connect to ScanVue5

® units as the bandwidth and response time is improved.

ScanVue5

® supports two activities—displaying item price and description and displaying a graphics slideshow. The unit has two primary modes of operation: an idle mode where a slideshow from 2 to 50 sequential images is continuously displayed, and an interactive mode where a customer scans an item and price and description information is returned by the host server. The four buttons on the front panel can be configured to only be active when in the interactive mode. In order to display product information, ScanVue5

® must connect to a host computer that has the product information stored in its database.

If you are using an MS Windows network, we highly recommend Windows NT, 2000,

ME, or XP. Windows 95 and 98 can be used as a server for ScanVue5

®

, but they are not supported. NT 4 Server and Windows 2000 will provide the best performance in terms of response speed, especially if you are using an RF wireless system rather than hardwired Ethernet (10/100baseT).

Network Activity

ScanVue5

® includes servers for FTP (port 21), ProductInfo (port 1283), and clients for

FTP, SMB (Windows networking), ProductInfo (Product Information Protocol) and QFX

(Quick File eXchange). FTP, SMB or QFX can be used to get the graphics files for

ScanVue5

®

’s slideshow. SMB is the default mode.

ScanVue5

® requires a file server for storing graphics files and a ProductInfo server (host or back office computer) for the price/description database. These servers may be (but don’t have to be) on the same physical computer. The file server must have the

ScanVue5

® initialization file (ScanVue.ini) in its POS shared directory (if SMB–based) or the default directory for FTP or QFX, and may also have font, graphic, and slideshow script files. The file server can be a Windows system, or an FTP or QFX server on any type of hardware or OS provided it runs TCP/IP.

ScanVue5

® sends the UPC number read from a barcoded item placed under the scanner to the ‘ProductInfo’ server on the host computer which uses this number as a key to find the item in the price and description database(s). After the item records are retrieved, the host application prepares the response and sends it back to ScanVue5

® where the information is displayed. The response can be text only, graphics only or a combination of text and graphics.

ScanVue5

®

Configuration

There are three ways to configure a ScanVue5

® unit:

1. Using its internal barcode reader to scan special purpose barcodes.

2. Commands sent across the network using the UnitConfig or modeset programs

3. Following the procedure in the ‘Quickstart Guide’. Of course ScanVue5

® must be able to communicate with the server on the network before its configuration can be changed on the network.

If you are using wireless RF units, you must enter the ESSID of the access point you are communicating with via the barcode reader before the unit will associate with the access point. Additionally, if your network uses WEP or WPA, ScanVue5

® must be setup to match the access point.

Quickstart

The CD–ROM contains the ‘Quickstart Guide for Scanvue5’ (P/N 37681–01). The guide applies to all Scanvue5 models and describes how to simply configure your units to match the network settings using a desktop PC and a crossover cable or a passive hub

(see page 4). This is the easiest way to bring up the first few units without the added complications of a large network.

Configuration Information Screens

When ScanVue5

® boots up, two configuration status screens (Fig. 9 and 10) are sequentially displayed which show the current settings of the unit. Each screen is displayed for 10 seconds then the unit will load the slideshow from the server and start running. These screens can be displayed at any time by scanning the ‘show config screen 1’ and ‘show config screen 2’ bar codes shown in Appendix A. In software versions later than V4.15, wireless RF configurations display brown text on a light green background and hardwired Ethernet units display yellow text on a blue background.

UnitConfig Program

Configuring ScanVue5

® units over the network requires a GUI program called Unit

Configuration which is installed from the CD–ROM. Generally, configuration by special barcode is kept for those occasions when a devices network configuration is incompatible with the local network. Changes can be made off–line that will allow the unit to connect to the network, just like the ‘Quickstart Guide”, but without needing the PC. Appendix B


ScanVue5

®

Mini Kiosk

User Manual

M37574–01T


describes this method. Once the unit is network compatible the rest of the configuration can be done through Unit Configuration.

Unit Configuration is a VisualBasic

® query and configure any ScanVue5

® program that provides a simple graphical way to unit. It uses the ScanVue5

® mode commands

(Chapter 5) to setup the unit. This program is available in both source and executable form.

Modeset is a DOS command line program equivalent to UnitConfig that can query and set modes through a text file or directly from the directory prompt.

Ex: modeset [mode value] sets the mode to the specified value modeset –g [mode] returns the value of the mode modeset lists all non-hidden modes and their values

Using Unit Configuration

When the program is first started, all boxes in the screen are blank. Enter the IP address of the ScanVue5

® unit you wish to change in the Unit IP Address box. Click the Read Modes button–all the Modes and their Content (values) will be read from the subject unit and displayed as shown in Fig. 9.

To change a mode; highlight the New Content box in the same row as the mode you want to change by clicking on it. Enter the new value in the box and click the Set Mode button. If the value is accepted, the box and the button will turn green. If it is not accepted, the box and button will turn red. Now click the Commit button, this will commit the change to flash memory in the ScanVue5

® unit. Multiple changes can be made before committing them. If any of the changes are not accepted, the Set Mode button will turn red and those changes marked in red were not made.

Clicking the Close button will blank the screen including the IP address box and allow a new IP address, hence a new unit to be selected.

Clicking the TextReset button will apply changes made to text modes so they can be seen immediately. As with other modes, the changes are not permanently stored until the Commit button is clicked.

The SaveToFile button will save the setup to a text file where it can be stored and printed if necessary. This is usually done for troubleshooting or maintaining hard copy records of each unit’s configuration.

The Restart Unit button will cause a ‘soft boot’ of the selected unit.

Clicking on the Help button brings up a help screen that is a brief overview of how to use the program. Additionally, the light color area at the bottom of the screen will display context sensitive help for each mode as the mode is highlighted. For some modes, the values available are indicated in this area. Other modes (for example Serial Number) cannot be changed and will always turn the New Content box and Set Mode button red.

The Exit button closes the Unit Configuration program.

WEP Types

ScanVue5

® supports 2 different types of WEP (Wireless Equivalent Privacy) encryption in software versions 4.12 and later. WEP encryption is set by the WEPEncryption mode.

WEP Description

There are 4 unique encryption keys WEPKey1 through WEPKey4. Each key contains

10 hex digits for 40–bit encryption or 26 hex digits for 128–bit encryption. Default value of the keys is a string of zero digits of the appropriate length.

The mode WEPKeyIndex determines which of the 4 keys is used. The default is

WEPKey1. The selected key must match the type of encryption selected. For example; if WEPEncryption is set to SHARED128 and WEPKeyIndex is set to WEPkey2, then

WEPkey2 must contain 26 hex digits (or 128 bits). WEPkeyindex and the encryption data can be set by barcode in software versions after 6.12.

Note: If the encryption type is changed, ScanVue will not verify the keys already stored are appropriate for the new type.

Exception—If you are using Symbol Technologies access points, they do not support

Shared System WEP encryption.

Setting WEP

Before you start:

1. The WEP encryption mode and WEP keys for the network you are installing to must be known.

2. The WEP encryption mode and WEP keys in the access point and the Scanvue5 unit must match exactly or they will not associate.

3. When installing and configuring a new or replacement Scanvue unit into a network running WEP, you must disable WEP at the access point or the Scanvue5 unit will not associate with it.

4. WEP keys are set using the UnitConfig program.

5. If you do not want to disable WEP on your network, an alternative method is to bring up the Scanvue5 unit offline, for example on a laptop, to set the WEP keys—all the rules still apply but the WEP keys can be loaded without disabling WEP on your network and UnitConfig can be run locally rather than on the network server.

6. The 3 rd option for loading WEP keys is by barcoding them into the unit. You must be able to generate and print the necessary barcodes to use this method.

Loading WEP Keys from Network

1. This procedure applies to either on-line or off-line computer connections

2. Disable WEP in the access point and boot up the Scanvue5 unit. It should boot up and associate (connect) with the access point.

3. Run the UnitConfig program.

4. Select WEPEncryption mode and set its value to one of the 3 choices shown in the table above. If WEP if not being used, leave its default setting of NONE.

5. Select WEPKey1 through WEPKey4 and set all 4 key values.

6. Using WEPKeyIndex set the key value you are using.

7. Commit the changes and reboot the Scanvue unit. New WEP settings will take effect when the unit has finished rebooting.

8. Enable WEP on the access point–provided the WEP encryption mode and WEP key selected on Scanvue5 matches the access point settings, Scanvue5 will associate

(connect) seamlessly.

Loading WEP Keys by Barcode

1. The unit does not have to be connected to a computer to load WEP keys by barcode.

2. Preferred format is Code 128 and hex digits A-F should always be upper case

3. Set the WEP encryption mode being used.

Relational Data Base

The API (Application Programming Interface) is a description of the ProductInfo protocol that enables the host computer to communicate with ScanVue. It is not a physical piece of hardware. Both ends of the API are physically the same piece of software.

ScanVue only performs 3 functions:

1.

Scan the product UPC (barcode) and send it to the HOST computer across the network.

2.

Accept the response from the HOST and display the information appropriately

3.

Automatically download a slideshow from the HOST and play it.

Overview

A generic protocol called ‘ProductInfo’ has been created especially for interfacing price verifier units such as ScanVue5

® with the back office server that holds the database containing item prices and descriptions. Implementations of ProductInfo directed at specific hardware platforms, ScanVue5

® in this case, are a subset of the full protocol.

This is one part of the API or Application Programming Interface for that specific device.

The other part of the API is concerned with configuration, control and setting modes.

Both parts are covered in detail in this Chapter.

The application that links ScanVue5

® and the back office server’s data must reside on the server. Almost any platform that runs a TCP/IP network can be used as a server.

Known hardware platforms in use include AS400, VAX and Wintel. Software platforms include Windows NT, UNIX, Linux, and VMS, running Oracle, SQL or other databases.

Software Developers Kit (SDK)

The CD–ROM shipped with ScanVue5

® contains the following items:

 SetupServer.exe program (IEE logo). Creates the necessary directories on the server and installs all required files and utilities into them.

 UnitConfig.exe install program (IEE logo). Installs the unit configuration program into the POS directory on the server. UnitConfig is a GUI program used for setting up ScanVue5

® from the network. Written in VisualBasic, the .exe, VB sources and an OCX are provided. When installed the program has a wrench logo.

 User manuals, quickstart guides and other useful documents in Acrobat (.pdf) format.

 Source code for demo servers and some utilities. The sample programs demonstrate communications with ScanVue5

® using the ProductInfo and QFX protocols and include ProductInfo and QFX servers. The VB sources and an OCX are provided for the Unit Configuration program so it may be embedded in the host application. All other programs are written in ANSI C and have been compiled and run without modification under NT, linux, UNIX, and VMS. QFX is a faster, lower overhead alternative to FTP and SMB and provides the added benefit of supporting graphic files in any format.

 A number of useful freeware and shareware utilities.

 ScanVue5 ® requires images in either GIF or FIF (Fast Image Format), ¼ VGA

(320x240 pixel) format. We recommend the use of ImageMagick for image file conversion from other formats into either GIF or uncompressed form. ImageMagick is a collection of tools and libraries for reading writing and manipulating images in 68 standard formats including TIFF, JPEG, PNG, PDF, PhotoCD and GIF. Information on ImageMagick can be found at www.imagemagick.org

ProductInfo Protocol Description

ScanVue5

® has an embedded protocol engine that uses TCP/IP to send the UPC barcode number from the price verifier to the host computer, and return the price and description information retrieved from the host computers’ database by its resident application.

ProductInfo is a TCP based, bi–directional message–passing protocol that uses the same format when moving data in either direction. In normal operation, the client opens a connection for each request generated, usually a scanned barcode, and keeps it open until the server instructs the client to close it. The client can also wait for the server to open a socket thus allowing asynchronous operation.

An optional non-normal mode provides a permanently open socket so the server can continuously monitor the state of the client. This mode was created specifically for a customer.

The protocol also sends events marking a change of state (opening or closing) of any of the four optional front panel switches. These events may be used by the hosts resident application to control functions or modes within the application, for instance to change language displayed when a switch is pressed.

An abstract system level diagram showing the relationship between ScanVue5

®

, the network and the host computer is shown in Figure 14. The API is shown at both ends of the network for clarity. In practice, the application to interface the host computer server to ScanVue5

® will reside on the host computer.

In the interest of robustness, both ends accept any message whether defined or not, invalid or unknown messages are simply discarded. A maximum reasonable message length may be used as a means to detect implementation bugs that could result in

loss of synchronization. Such errors terminate the connection. If the client detects it, it may send an error token following re–establishment of the connection in order to log the error on the server. If the server is able to detect this condition, it can log it directly.

When the server receives a product query from the price verifier, it must respond even if the message is just to terminate the connection. Following submitting a query, the client may choose to take an error action if it receives nothing from the server within a defined timeout period. The server can make capability queries and/or mode changes before, during, after, or in lieu of sending any response. If the server wishes to space messages more widely than the client’s default timeout, it must send a ‘Set Mode’ packet to change the timeout; this need only be done once per query, but must be done on each query.

The client may send capability messages regardless of whether the key name is known to the server and the server may retain this information. When the server needs to know the value of one of these capabilities, it can consult this retained information. If it is not known, a capability query may be sent and the server may wait a moment for a reply to be received. This reply will asynchronously update the server’s information, and the value should be found there by a subsequent lookup following the brief interval required for the client to respond to the query. If it remains undefined, it can be assumed that the client declined to respond, probably because that capability name is not known to it.

Mode settings allow the server to select between optional behaviors or parameters in the client. Theoretically, this can work both ways. If the server wants the client to adopt a

certain mode setting, it sends the command and the client will respond appropriately. If not, an error report may be generated in response. Mode settings occupy a separate name–space from the capabilities table. A mode setting could be used to change the timeout value the client uses to decide that a socket connection has broken.

Error reports are used primarily as a debugging tool. The string starts with an error number, optionally followed by white–space and explanatory text.

In the nominal case, messages consist of a length, followed by a token, possibly followed by more information as specified by the length and the token. In the trivial case, the message consists solely as a NUL–terminated text string; this is the case when each of the four bytes of length field is an ASCII printable character. When such a message is received by the server, it is interpreted as a product query; it optionally contains the client’s identification and white–space preceding the product code. When received by the client, it is interpreted as a single, textual response to a query.

Protocol Implementation Rules

1. Mode values changed during a query session are only retained during that session.

2. The host can make “permanent” changes to mode values for query sessions by connecting to the ProductInfo protocol port (Port 1283) of the client and setting the values. As long as that connection is maintained, the new values will be used in all further queries.

3. Whether a “permanent change” will survive a power cycle of the client is implementation dependent. Clients may provide special functions to record mode information in non–volatile storage.

4. Query sessions are best kept limited to information that is to be displayed immediately, so that further queries can be answered.

5. Mode values that start or end with whitespace must be sent enclosed in double quotes. These quotes are removed when the value is stored. Double quotes within the string are treated as part of the value.

6. When using double-byte font files such as the Kanji font (7640 characters), text strings must be defined as Big-Endian or Little-Endian depending on the server.

ScanVue5

®

Implementation Rules

1. ScanVue5

® maintains an asynchronous ProductInfo server. The host can open a connection and send messages to this listener at any time.

2. ScanVue5

® sends carriage return/linefeed pairs to indicate an end–of–line (<NUL> marks end–of–string) to accommodate various host computers, but will accept either or both.

3. When started up, ScanVue5

® makes a copy of the setup information stored in the non–volatile memory. Changing a mode’s value modifies this copy and is the source of mode values when a mode request is executed. Setting a mode does not preserve the new value in non–volatile memory; the new value(s) must be specifically committed. A second copy of the setup information is kept as the current value set. This copy is modified by the SCANVUE.INI file contents.

4. The values that are read for modes are those default values and may not reflect the current operational values. This will occur when the initialization file overrides the default values. Setting values sets what will be recorded to non–volatile memory, but may not affect immediate operations.

5. Changing a mode’s value may not cause ScanVue5

® to immediately change its behavior; some changes require the unit be reset before they take effect.

6. The modes that are immediately affected when changed are: Timeout, TrivialComm,

SendUnitID, SendError, SendResponse, TextBackgnd, TextForegnd, and

QueryPrefix.

7. The text display modes (TextHPos, TextVPos, TextRows, TextCols) can be forced to take effect by setting the TextReset mode to TRUE.

8. The QueryPrefix can contain binary information. To set a QueryPrefix with binary values, use a ‘C’ language format string for the value. ScanVue5

® accepts “\x” followed by two hex digits as a single character with the value of the two hex digits; no other sequences are recognized.

9. When powered up, ScanVue5

® will attempt to register with the host system. If it cannot do so, it waits 10 seconds and tries again. After each failure, it waits one second longer than the previous time, ad infinitum. Additionally, whenever ScanVue detects that the initialization file has changed, it will make one attempt to re–register.

This allows a host computer that has gone down to force all ScanVue

® s to register without knowing which or how many ScanVues

® are on the network. Registration can be selectively disabled.

10. Text transfers using the default extended ASCII character set shown in Appendix D should be sent in nominal mode. This is because many libraries do not properly handle the characters outside of the usual ASCII range (32–127) correctly.

Programmatic Modes

Programmatic modes are for use within another program and cannot be read or set interactively with UnitConfig or modeset. For example, UnitStatus is a mode used within the ‘heartbeat’ utility program to report on the status of the unit being read. These modes may also be used within your own program.

GiveHelpText Appends help text to null MDSQ requests.

Timeout

UnitStatus

The maximum wait time, in hundredths of a second, for an initial response to a product information query. Valid for the current connection only.

Reports on the state and activity of the unit. Returns a single line of values separated by spaces. Counters restart from zero if maximum count exceeded or unit is reset. In order the values are:

QFX Quick File Transfer Protocol

QFX is a very low overhead protocol that is a much simpler and faster alternative to FTP for moving files quickly across the network. There is no authentication. The QFX server allows only read access to files in and below its default directory; this is the extent of security.

QFX packets consist of a 4–byte (network order) packet length, a 4–character token, and possibly data. Packet length includes the 4–byte length field.

Tokens are:

INFO

SEND

DIFF

ERRR

INFO exchange: request:

File information request/response

File send request/response

File timestamp comparison

Error response response:

[ length ][ INFO ][ filespec <NUL>]

[ length ][ INFO ][ YYYYMMDDhhmmss size <NUL>]

Four digits for year, two each for month (January is 01), day (01–

31), hour (00–23), minute (00–59), and second (00–59), followed by a single space–character, and finally the size of the file, in bytes.

response: [ length ][ ERRR ]

Requested file does not exist or request is malformed.

Explanatory message is optional, should be string consisting of number, whitespace, optional text.

request: response: response:

[ length ][ SEND ][ filespec <NUL>]

[ length ][ DIFF ][ filespec <NUL>][ YYYYMMDDhhmmss<NUL>]

[ length ][ DIFF ][ Bool ]

Bool value is TRUE if the file’s date/time are DIFFERENT than the provided timestamp and FALSE if it is the same.

[ length ][ ERRR ]



[filespec] uses UNIX style forward–slash directory notation. It is the responsibility of the server to convert the notation to the native method, and to guarantee that the path cannot extend outside of the default directory.

The directory ‘/’ refers to the current directory; a leading ‘/’ is ignored. The QFX server must guarantee the requested file is in or below its current directory.

Line–terminators are newline characters; carriage returns are optional.

The server is responsible to read text files and transmit them with appropriate line breaks. Specifically, this applies to VAX/VMS.

Using Graphics Characters

ScanVue5

® with an AMLCD can display graphics characters such as Kanji and Chinese

(ideograms) as well as standard Latin text characters. The graphics font file is downloaded into the price verifier at boot up time by a command line in the scanvue.ini

file. As only one font file can be stored at a time, the characters displayed are limited to those in the currently loaded font set. Certain font files contain other characters; for example the Kanji font set also contains English, Greek and Cyrillic characters and GB

(simplified) Chinese includes 128 US-ASCII characters. Note: although standard US-

ASCII characters are single byte coded, using the US-ASCII characters in the GB

Chinese font file requires the double byte codes specified in that font file.

Displaying graphics characters requires two hex bytes (double-byte text) per character due to the large number of glyphs in the font set (Kanji has 7,640 characters). The rules for using double byte text are shown here.

Double byte text strings come in two types, Big-Endian and Little-Endian. The server hardware determines if you will need big endian or little endian strings. Double byte strings sent in trivial mode must be double NUL (00 00) terminated whereas strings sent in nominal mode do not have to be.

Big-Endian text strings start with the bytes FE FF and end with the bytes 00 00.

Ex: FE FF b

1 b

2 b

3 b

4 b

5 b

6 b

7 b

8 b

9 b

10………..

00 00

Little-Endian text strings start with the bytes FF FE and end with the bytes 00 00

Ex: FF FE b

1 where b

In scanvue.ini, double byte strings can be used for wallpaper but the text must start with

<< instead of < or // instead of /.

For the Demoserve data file (data.dat) on the CD-ROM, the characters |> indicate a Big-

Endian string and |< indicates a Little-Endian string. Note: Demoserve actually sends the FE FF or FF FE bytes not |> or |<.

A utility program, dmp2gdf, provided on the CD-ROM creates a .gdf (double-byte) font file from a single byte ASCII font file.

Using Input Devices

Scanvue5 has four optional types of manual input device in addition to the standard barcode scanner. Each type of manual input device generates message tokens with a similar message packet structure called EVENTS and thus they are all treated together in this section.

Activating any of the input devices—barcode scanner, touch screen, keypad, magnetic stripe reader or push button, causes Scanvue5 to transmit the input data, usually a string of alphanumeric characters, to the host computer for further action by the server based application.

Touch Screen

The digital touch panel is organized in a 16 column x 12 row matrix. The LCD screen resolution is 320 x 240 pixels (¼ VGA). Thus each of the 192 discrete touch areas formed by the matrix is a 20 x 20 pixel square, which is dimensionally ¼”x ¼” and defines the maximum resolution of the touch screen. Resolution scaling (increasing the dimensional size of the discrete touch areas) may be set for each axis independently down to 1 column x 1 row—in other words where the whole display screen is a single touch button. Resolution scaling can also be changed dynamically by the users application. In fact, the internal resolution is changed to be 2:1 for increased sensitivity.

reported position={measured position x vertical (or horiz.) scale}/max. resolution rounded to the next highest integer.

Factory default setting is at the touch screens highest resolution of 31 x 23 where the top left corner co-ordinate is y,x = 0,0 and the bottom right corner co-ordinate y,x = 23,31.

Touching the panel anywhere within a specific 20 x 20 pixel area or resolution scaled area will stuff the start mask and y,x co-ordinates of that touch area and the number of

10 millisec clock ticks since the last event into the EVNT packet and transmit it to the host computer application.

Keypad

A 20 key keypad mounted on the right side of the Scanvue5 unit. When a key is pressed, its ASCII code will be stuffed into the EVNT packet and transmitted to the host computer. Each key pressed will generated a separate EVNT packet.

Push Buttons

Four mechanical push button switches located on the front bezel directly under the LCD screen. The buttons are strategically placed so the bottom edge of the display screen may be used for ‘soft’ legends allowing the application to navigate through multiple menu levels. This option is mutually exclusive with the touch screen.

Magnetic Stripe Reader

A three track swipe reader that reads data from any standard ISO 7811, ANSI , AAMVA or California DMV encoded magnetic stripe credit, loyalty or gift card. Decoded ASCII characters read from the 3 tracks are stuffed into an EVNT packet and transmitted to the host computer. Raw card data is not encrypted before transmitting it to the host. The data is transmitted as a serial stream as follows:

<S1> <DATA1> <ES> <S2> <DATA2> <ES> <S3> <DATA3> <ES> where S1, S2, S3 are the start sentinels for track1, track2 and track3 and ES is the end sentinel for all tracks.

Configuring

,

Scanvue5 for Input Devices

A multiplexer (MUX) PCB is installed in Scanvue5 units that have a touch screen or magnetic stripe input device. Pushbuttons do not require the MUX PCB however they cannot be used when the MUX is installed. The keypad may be run from the external serial port without using a MUX however this precludes using a printer on this port.

Scanvue5 must be running version 5.02 or later to support any of the input devices.

Enable Multiplexer

The multiplexer PCB must be enabled to operate with input devices in versions 5.02 and earlier. In versions later than 5.02, the multiplexer is detected and enabled automatically and this mode will not show up in UnitConfig.

 Set MUX ENABLED to TRUE

Start Event and End Event Masks

Start and end event masks define the beginning and completion of a device activation period. For instance, a pushbutton start mask defines when the button is pressed and the end mask defines when it is released. The mode values are 8 digit hex masks (32 bit) which define the type of device initiating the event as well as the button position (see

Table 1). Start and end masks are always present in the transmitted packet when the device is used but for most applications the end event mask should be disabled by setting it to 0 in UnitConfig. Set the mode values (mask settings) as shown in Table 1

Push Buttons

The time the button is pressed and held down can be measured by setting the start and end event masks and reading the number of 10 millisec clock ticks between them. For example, this could be useful in an application to discriminate between a ‘short’ press and a ‘long’ press.

 Set start mask. Set end mask only if required for timing

Touch Screen

The touch screen has only start events, however 2 or more touch areas pressed simultaneously will be recorded and transmitted in the same packet. The clock tick count in this case is the time elapsed from the prior event.

 Set start mask only.

Structure of EVENT packet

ProductInfo section but is repeated here for completeness.

2. EVENT packets report push button, touch screen and keypad activations but each device type will send a separate EVENT packet.

3. Separate packets are sent for start events and end events (if used).

4. Push button events do not generate data (only whether they are pressed or not pressed) and thus do not set the parameter values.

5. Pressing the touch screen transmits a (minimum) 33 byte message packet to the host computer in the following general format.

ScanVue420 Vacuum Fluorescent Display

Note: references in this manual to the use of graphics images, double-byte text and downloaded fonts are not applicable to the Scanvue420 model.

Description

ScanVue420 has a 4 line x 20 character x 5mm high, 5x7 dot matrix vacuum fluorescent

(VF) display and shows text in a fixed font size and pitch. The default character set is

US-ASCII extended with 64 European characters. There are three (3) more 64 character extended language sets Cyrillic, Hebrew and Katakana that can be selected from the

UnitConfig program by entering the character set name in the mode ExtCharacterSet.

This feature allows the end user to set the character set to the language of choice.

Once ScanVue420 is set to display one of these optional character sets, any message sent to the display will use the characters in that chosen language set. The language character sets are shown in Appendix D and always contains the US-ASCII characters shown in Table 4 plus one of the optional 64 character sets shown in Tables 5-8.

The user may change any or all of the 3 internal customer messages (factory default is

English) into one of the 4 language character sets available on the VF display. This will allow the user to display customer messages in the language of the country the unit is installed in.

As this model cannot show graphics or inherently run a slideshow, the customer greeting screen shown in Figure 15 is normally displayed as a static screen. It is possible to create a loop of linked text messages on the server side that can be sent to ScanVue420 in a timed sequence to create a ‘text slideshow’.

Operation

When ScanVue420 finishes booting up it will display the info status screens first, then the logo screen and finally the static greeting screen shown in Figure 15. This screen will be continuously displayed until either an item is scanned or the host server sends a different message.

true so the server application can discriminate between VF and LCD unit requests and not send graphics images to VF units. A VF unit receiving an image will display the default no response message then will display a blank screen. The host server should respond to a VF unit with a formatted text information block (TIB) of all 80 characters, including the blanks, to locate the actual text in the required positions on the lines

(Figure 16)—there are no direct text formatting commands in the present version.

Figure 16—Item Description & Price Display

Text Slideshow

If you want to send multiple messages in sequence, this must be controlled from the host server end. For instance, a text based series of messages for continuous advertising could be sent to the display under control of the host. The host would have to have the sequence of messages in a message file (or multiple small files) and send them in a sequential loop with a delay for adequate viewing time. The loop control would require an interrupt when the host receives data from the ScanVue420 barcode reader to stop the message sequence, retrieve the item description and price, display it for a set time and then return to the message loop.

Changing Language Character Sets

Appendix D shows the VF displays’ default ASCII font set with 64 empty character codes between A0 and DF and the four extended language character sets that can fill these empty positions. Initially, the default character set is US-ASCII+European. The ASCII characters are always available but the extended character set can be changed from

UnitConfig by selecting the mode ExtCharacterSet and entering the appropriate value in the New Content box. Only one extended language at a time can be loaded.

Customer Messages

Three (3) internally generated customer messages are built into ScanVue420. These messages give specific information to the customer while using the price verifier. Text content and language can be changed for use in other countries. The messages are:

Checking…...One moment please Message displayed when an item has been scanned and there is a delay in returning the price and description—usually due to heavy network traffic.

Unavailable…..please try later Message displayed if ScanVue420 times-out before the server returns price and description or an error message—usually means the network is down.

Welcome to IEE ScanVue420….Scan your item here Greeting screen (see Fig 15).

This is the static ‘greeting screen’ that is displayed to a customer.

Changing Messages

1. Change the ScanVue420 character set to the one you want to use from UnitConfig.

Make all the changes before restarting. The default character set is US-

ASCII+European.

2. When creating new messages, standard characters (that is, those available on your computer keyboard) can be entered directly from the keyboard. Non-standard characters must be entered in hex code form. Hex codes consist of 4 hex digits

(\xdd; where \x specifies that a hex code follows, and dd is the hex code for the character you want as shown the character code table ) but occupy only 1 character space on the display. See examples in Appendix H–Applications Notes.

3. Checking… and Unavailable… and Welcome to IEE… messages can be changed by entering the new text in the msgChecking or msgUnavailable or BannerText rows in the UnitConfig program screen. Non-standard ASCII characters must be entered as hex codes as described above.

4. After changing these messages, click the Set Mode, Commit and Reboot buttons in sequence. The unit will reboot and the new messages will be saved and active.

The text file string in BannerText to create the default message is shown below. In this example \ is used to define the start and end of the text string and * to denote a space.

The example is only shown this way to make it clear, and is not required when you create an actual message—however the blank spaces to get the correct alignment are required.

\*****Welcome*to*******IEE*ScanVue*420********Scan*Your***********Item*Here******\

Appendix A—Configuring with Barcodes

Barcode Reader Settings

Note: the barcode reader is shipped with setting changes “locked out” and cannot be re-configured in the field. This is done at the factory because barcode readers have been maliciously changed by customers in the field. If you need to change the barcode reader settings, reboot the unit and scan any new configuration barcode(s), the first one which has to be within the first 60 seconds of the boot cycle. Do not wait for the unit to finish booting—it will be too late. This will “unlock” the scanner temporarily and allow you make any required changes. After re-booting, the scanner will be locked again with the new configuration mode set.

To set the scanner to its permanently “unlocked” mode, re-boot the unit and scan the

“recall defaults” barcode within 60 seconds. The scanner will then accept any setting changes at anytime.

Units shipped after 3Q2006 use the Metrologic IS3480 scanner rather than the model

IS6520. The IS3480 is a physically more compact scanner but otherwise will function identically to the IS6520. The default settings of the barcode reader can easily be changed by directly scanning the specific barcodes shown in the MetroSelect ™

Configuration Guide. Download a copy of the Guide (document # MLPN2407.pdf) found under Omniquest ™ model # IS6520 or the xxxxxxxxx IS3480 Guide on the Metrologic™ web site at www.metrologic.com/proguide.htm

Each label will generate a single beep when scanned properly, then a double beep to acknowledge the operation is complete.

3. Scan the specific labels (listed in Table 1) required to change the configuration to your network’s parameters. Each setup label will beep once when scanned correctly. ScanVue5

® will display the raw code, then the setup name and entered value. Frequently used bar codes are provided as a .PDF file on the CD–ROM and may be printed and used directly from the page.

4. When all the setup labels have been scanned in and visually verified, scan the Save

3

Numerical values (‘L’ and ‘NNNQ’) are decimal. Numerical values must be followed by a non–digit character. Purely numerical parameters (e.g., Product Info Port) should be followed by an upper–case alpha character to prevent confusion caused by check–characters and stop codes.

Command barcodes must be at least six characters long, including the two–character prefix but excluding the check character and any start and stop characters. Extra padding characters may be added to guarantee this. Padding characters should be upper case alpha characters and are ignored. Numerical values may be zero padded (e.g., ‘0001’ instead of ‘1’).

It is highly recommended that barcodes be created in Code 128. The barcodes shown in the table are in Code 128 format. Some other codes generate numeric check characters which MUST be terminated with an alpha character to prevent ambiguity.

The following single and paired characters should NOT be used in barcodes: A, F, E0, FF, B1, B2, B3

Appendix B—ScanVue5

Initialization File

Overview

A default initialization file (scanvue.ini) is placed into the share directory on the server by the installation program when the server software on the CD–ROM provided is installed.

The .ini file must be on the server, in the share directory and the ScanVue5

® units which are hard coded to look for the .ini file in the share directory, must find it or they will not be able to establish a connection to the network.

Software V6.20 and later will also detect filename realscan.ini as well as scanvue.ini.

This change ensures that existing NCR installations can be run interchangeably. The scanvue.ini file is read by every display on that network server once a communication link is established. The .ini file controls the behavior of every unit linked to that server.

As well as defining the defaults for text display, colors and wallpaper, the .ini file provides a way for ScanVue5

® units to be grouped together and access different slideshows as a group. For example, in a multi department store, each department can be running different slideshows at the same time, each one showing promotions or teaser advertising tailored to that department’s specific products. Slideshows can be changed as desired with specially created versions for holidays or sales events.

Real Time Clock

A real-time clock display can be superimposed on the LCD screen (see Fig 17) as defined in the scanvue.ini file. ScanVue5

® maintains an internal clock tick counter but does not store ‘real time’. Date and time are initially set by the NTPServer and TZOffset modes in the.ini file (see example p49) or with UnitConfig and should be periodically updated by the DateTime mode from your server application. The host must be running an NTP or similar time server that the application can access for the current date and time.

The clock display font, foreground and background colors and position on the screen are defined independently of the font used for text display. This is the only case where 2 different fonts can be used at the same time. The clock feature is intended for internal company purposes rather than for customers and may be used for example, as a time clock for employees to clock in and out of the store by scanning their ID cards under the barcode reader.




User Manual

M37574–01T

Figure 17–Real Time Clock Display

Rules for the ScanVue.ini File

1. The .ini file is a text file consisting of sections for specifying different parameters.

Each section is marked in enclosing square brackets i.e. [Group].

2. Sections may be in any order. Initialization lines may be in any order within a section.

3. Lines that start with a single quote ( ‘ ) or octothorpe ( # ) are comments. Blank lines and white space (except possibly in a value field) are ignored.

4. Initialization lines consist of a token, followed by zero or more blanks or tabs, followed by an equal sign, followed by zero or more blanks or tabs, followed by the initialization value for the token, i.e., TOKEN=Value

5. Tokens/Value pairs may be directed to an individual unit by preceding the token with the Unit ID enclosed in angle brackets i.e., <Tools1> Text_Rows = 4

6. Tokens/Value pairs may be directed to all units in a group by preceding the token with the Group name enclosed in angle brackets i.e., <Shoedept> Text_Fcolor =

Green.

7. Group names may consist of alpha and numeric characters only.

8. Tokens and sections that are unrecognized are ignored. Default values are used when a token is not present.

9. Values are set in the order they appear in the file. If there are duplicate tokens in a section, the value used is the last one on the list except when a Unit ID is specified.

If the Unit ID is specified, only that token/value pair will be used, regardless of the position within the section.

10. A font file must be specified (replaces the default font) if the text foreground and background colors are to be specified.



User Manual

M37574–01T


11. If the clock function is being used, a second font file may be specified for the clock display. This is the only case where 2 font files can be used at the same time.

12. The NPTServer mode sets the time when scanvue.ini is run (at boot time). To keep the clock accurate, periodic updates using the TimeDate mode from your application is recommended.

Appendix C—Creating a Slideshow

This section contains detailed instructions for creating a slideshow file. There are two ways to create a slideshow. A program called Slideshow Editor and its a User’s Guide is available on the CD-ROM. An easy way to make a slideshow without having to learn to use a new program is to use a text editor like Windows

®

Notepad to create the script necessary to run the graphics images (slides).

A slideshow is a file containing graphic images and a script (the instructions) on how these images are to be displayed. Slideshow files reside on the network in the servers’ share directory and are ‘pushed’ to the displays by commands in the slideshow file and stored in the unit’s RAM memory. The slideshow is executed from within the unit.

A slideshow file consists of a sequential list of references to graphics images in the order in which they are to be displayed, specifying the duration each image is displayed. The file uses Token=Value pairs to define the sources of the image files. Blank lines, lines starting with a single quote ( ‘ ) or an octothorpe ( # ) are ignored, as is white space around tokens or the equal sign separating the token and its value.

Creating a Slideshow File

The SLIDESHOW section is a script that is interpreted by ScanVue5

® as it is executed.

Slideshow entries consist of two items of information: the slide image by sequence number and the duration the image is to be displayed in ticks where a tick=1/100 second. A FRAME may be defined to equal a number of ticks; for example FRAME=100 makes FRAME = 1 second. Frame can be shortened to F, which can then be used as the duration (F1 = 1 second or F3 = 3 seconds)

CAUTION:

DO NOT DISPLAY A FIXED IMAGE FOR LONG PERIODS OF TIME AS THIS MAY

CAUSE A PERMANENT LATENT (GHOST) IMAGE ON THE LCD. THE LCD WARRANTY DOES

NOT COVER THIS EFFECT.

This effect known as “imaging sticking” is caused by an ion charge buildup in the liquid crystal material and is inherent to all AMLCD displays. The LCD manufacturer recommends no longer than 5 minutes before changing the image, the purpose being to turn ‘off’ the pixels that are ‘on’ for a period of time. This will prevent image sticking from occurring.

Using Multiple Graphics Windows

Several graphics windows can be displayed on the screen simultaneously. Multiple window displays are specified from the slideshow file. Each window can be individually sized, positioned on the screen and its display time and delay time to the next window selected. Figure 18 (p64) shows the timing diagram for the example slideshow file and the overlapping window display is shown in Figure 19.

Images used during multiple windows presentations must be sized prior to running them in the slideshow file. It is also recommended that the same color palette be used for



User Manual

M37574–01T


each of the images as the last palette loaded will affect all previous images (windows) on the screen at that time. Images can be edited with any good commercial image editing program such as CorelDraw or Adobe Photoshop. A shareware program, ImageMagik, is provided on the CD-ROM. A full screen image is 320x240 pixels thus image windows will want be smaller than this size depending on how the multiple windows are displayed

For example, if 4 non-overlapping images are used to fill the screen, each image will be

160x120 pixels. The images may also overlap each other. The minimum recommended image size is 160x120 pixels—any smaller than this gets difficult to see unless it’s a logo or a name.

Rules

1. Each of the 4 items can be on the same line, separated by commas or on different lines.

2. The text command SLIDE in an entry can be replaced with the percent sign for brevity.

For example; SLIDE15 would become %15.

3. Graphics image files (slides) must be in a 320x240 non–interlaced GIF–89a format.

4. Image files (slides) for multiple windows displays must be sized <320x240 pixels. All other image specifications apply.

5. The FTP server pushing the slideshow file to ScanVue5

® must be set to binary mode.

Abstract: This specification describes a bi–directional message passing protocol called ‘Product Information Protocol’, that was created especially for retail store price–verifier applications. The protocol is designed to be generic and is not tied to any specific retail hardware device. Any network topology or configuration capable of using or connecting to TCP/IP will be able to support ProductInfo based applications.

The IEE Inc. ScanVue

 and ShopVue retail products use a sub–set of the

ProductInfo protocol to meet their functionality requirements. The specific implementations for these products are covered in their respective user manual application programming interface (API) section.

Introduction

The ProductInfo Protocol provides a network–based messaging system whereby a client can obtain item price and description information about specific products. This information can be in any form such as text, graphic images, sound or combinations. The protocol will be submitted as an RFC for the Internet community.

Protocol Types

There are two forms of the protocol: trivial and nominal. The trivial version consists purely of <NUL> terminated text sent from the client to the host, or from the host to the client. From the client, it is a product query; from the host it is a text response. This may not support all the features of any particular device, so nominal mode must be used for advanced features.

The trivial and nominal cases can be distinguished by examination of the first byte; in trivial mode it will always be a printable ASCII character—in nominal it will be zero (unless you are sending individual packets in excess of 16MB). When a trivial–mode message is received by the server it is interpreted as a product query; it optionally contains the client’s identification and white space preceding the product code.

When received by the client, it is interpreted as a single, text response to a query. In either case, sessions are closed by the server.

In the nominal case, messages consist of a length, followed by a token, possibly followed by more information as specified by the length and the token.

Symmetry

The format is the same in both directions but the implementations at either end may or may not understand all the same tokens. In normal operation, the client opens a connection for each request, and keeps it open until the server instructs the client to close it. The client can also wait for the server to open a socket, to allow asynchronous operation. Either side may act as client, or server, or both.

Errors

In the interest of robustness, both ends will accept any message whether defined or not

 invalid messages are discarded. A maximum reasonable message length may be used as a means to detect implementation bugs that could result in loss of synchronization; such errors terminate the connection. If the client detects a loss of synchronization it may send an error token following re–establishment of the connection in order to log the error on the server. If the server detects this condition, it can log it directly.

Following a query, the client may choose to take an error action if it receives nothing from the server within a defined timeout period.

Status Requests

The server can make capability queries and/or mode changes before, after, or in lieu of sending any response. The client may send capability messages regardless of whether the key name is known to the server; the server retains this information. When the server needs to know the value of one of these capabilities, it consults this retained information. If it is not known, a capability query may be sent and the server may wait a moment for a reply to be received. This reply will asynchronously update the server’s information, and the value should be found there by a subsequent lookup following the brief interval required for the client to respond to the query. If it remains undefined, it can be assumed that the client declined to respond, most probably because that capability name is not known to it.



User Manual

M37574–01T


Client Mode Changes

The notion of a mode setting is to allow the server to select between optional behaviors or parameters in the client. If the server wants the client to adopt a certain mode setting, it sends the command. The client will do so, if applicable. If not, optionally, an error report may be generated in response. Mode values are set by using token–value pairs. Mode values can be queried by sending the mode name alone. Error reports are used primarily as a debugging tool. The string starts with an error number, optionally followed by white space and explanatory text.

If the mode query is a zero–length string, ScanVue will respond with a <CR><LF> separated list of all supported modes and their types in the form “MODENAME=TYPE,SIZE” where TYPE is BOOLEAN,

NUMBER, or STRING, and SIZE is the number of bytes in the STRING and only appears for STRING. If the mode query is the single–character string “*”,

ScanVue will respond with a <CR><LF> separated list of all supported modes and their current values.

Error reports are primarily intended for debugging purposes. If enabled, error reports are sent if, for example, the host queries a capability that the client does not accept. Such error strings are in the format of a number possibly followed by white space and explanatory text. There is no assignment of numbers to specific errors, but the value zero should be reserved for non–error conditions.

Event: A client can support up to 32 application specific events and can report the beginning and end of each event with a 100 th second timer (which need not be supported). Events are mapped into a 32–bit word, in standard network order.

Clients may allow the host to enable and disable individual events, or to select reports only for starting or ending events. The packet header for events from

UnitID “Unit1” is:

Byte # 0 1 2 3 4 5 6

0 0 0 26 E V N

Immediately following the header is: the 32–bit map of events that have started since the last report, the 32–bit map of events that have ended since the last report, a 32–bit timer value and a NUL terminated string that is the sending unit’s UnitID. The bytes following the header if event zero started and event one ended at time 5 from UNIT1 would be:

0 0 0 1 0 0 0 2 0 0 0 5 85 78 73 84 49 0.

Appendix G—Application Notes

Wallpaper

Description

In its default configuration, scanning a barcode will bring up a ‘Checking…Please Wait’ message in yellow characters on a blue background. When the server returns the price and description of the scanned item a new screen will replace the ‘Checking…’screen.

A user–defined image called ‘wallpaper’ can be displayed instead of the default message while waiting for the server to return the product information.

Wallpaper is a static image that is displayed immediately after a barcode scan and is used as a graphic backdrop for the price and description text that follows the barcode scan query. If wallpaper has to display a ‘Please Wait’ or similar message, that text must be embedded into the image (this is not to be confused with text over graphics or mixed mode operation). Another purpose for wallpaper is to provide labels for the four optional pushbutton switches (see Fig 28). Again, these labels must be embedded into the wallpaper image.

Immediately following a barcode scan the slideshow is interrupted and wallpaper is displayed. The item price and description returned as a result of the barcode query are overlaid on the wallpaper image. This is true mixed mode (or text over graphics) operation (see Figure 29). After a user settable timeout, the wallpaper and text will be terminated and replaced by the slideshow until the next barcode scan.

Creating Wallpaper

A typical wallpaper might consist of a background image, for instance a company logo, with “Please Wait…” or a similar message in the center of the image and a one character high row at the bottom of the display containing text labels for the 4 switches

(if the switch option was ordered). This is a single homogeneous GIF image created using a suitable image editing program that allows text to be embedded into an image*.

A shareware image–editing program “ImageMagick” is included on the SDK CD–ROM.

Programs such as PC Paint, Adobe Photoshop or Corel Draw will do this easily if you are more familiar with them.



Remember, any image you create must be in 320x240 pixel, non–interlaced GIF89a format

Figure 27—Wallpaper Image

Using Wallpaper

Once the wallpaper image has been created, copy it to the \pos\graphics subdirectory on the server (assuming \pos is the share directory). The preferred method of loading the wallpaper image into ScanVue5

® is to include a line in the [Display] section of the

ScanVue.ini file MsgChecking = /graphics/wallpaper.gif where wallpaper.gif is your wallpaper image file name. The wallpaper image will be downloaded into ScanVue5

® the first time the scanner is used. An alternative way of loading the wallpaper is to enter the filename and path into the MsgChecking row in the UnitConfig program.




User Manual

M37574–01T

When a barcoded item is scanned and the wallpaper is displayed, price and description from the server must be sent back using mixed mode (text over graphics mode). The text is sent inside a TIB (text information block). The TIB is defined at the server in terms of # characters wide, # characters high and location in pixels (H,V) of the top left corner of the TIB. Character font, size, foreground and background colors must be defined and known before the TIB can be defined. The TIB boundaries (and the text inside the TIB) will then overlay the wallpaper image, in the color defined as the background color.

Figure 28—Text Over Wallpaper



User Manual

M37574–01T


Text Over Graphics (Mixed Mode) Operation

When text is sent to ScanVue5

® and overlays a graphic image without destroying the graphic, this is known as mixed mode (or text over graphics) operation. To use this mode of operation a graphic image file name is specified on the MsgChecking line in

UnitConfig instead of the default “Checking….Please Wait” text message. This image is called wallpaper and will appear every time an item is scanned with the barcode reader.

In addition, the TextDisplay line in Unitconfig must be set to MIXED.

Text over graphics may only be used with wallpaper—in other words, you cannot send a random graphic and then send text to overlay it. The implied restriction here is that the graphic image is always the same unless you send a new one to replace it.

In Mixed mode, text is displayed inside a text information block (TIB). The TIB is opaque and covers the image. As long as the TIB is smaller than the full 320x240 image size some of the image will show around the edges of the TIB. A TIB could be defined to be as small as 1 character wide x 1 character high and might only cover a small part of the image. If the TextTransparent mode in UnitConfig is set, the TIB becomes transparent and only the text characters are opaque. Depending on your application, this might have a more pleasing look.

ScanVue5

® can only have one 256–color palette at a time. When text is displayed any palette can be loaded. When text is displayed over a graphic the palette from the graphic should be used as it’s easier to modify the text color than to deal with a corrupt appearing image. The best way to handle this is to have your art department use the same palette for all their work or reserve certain indices for certain color values.

Default Text Setting

The default text setting is 7 rows x 20 characters. At the default font and character size, the TIB will cover the whole screen except for about 8 pixels top and bottom. If you do not change the default settings it will appear mixed mode doesn’t work correctly. We recommend you set the text to 2 rows or make the font much smaller before you start experimenting. Change it in the ScanVue.ini file.

Define the TIB using modeset commands. The parameters are height in # characters, width in # characters, background color, foreground (text) color and the location of the top left corner TIB in pixels from left and top edges of the screen.

Single TIB

The normal mode of operation after an item is scanned is for the wallpaper to display, a text message (TIB) is sent by the host and overlaid on the wallpaper and then the host should hang up. If the host doesn’t break the connection, ScanVue5

® will sit and wait for another TIB and will appear to be hung. It will eventually recover (~30 min timeout), but the preferred way to ensure this doesn’t happen is set the mode SingleQTrans to

TRUE. This will force ScanVue5

® to close the connection after the first TIB is received.



User Manual

M37574–01T


If you are sending multiple TIB’s, then set SingleQTrans to FALSE—however, the host must ensure the connection is broken after the last TIB sent or ScanVue5

® will sit and wait.

Creating Customer Messages on VF Display Models

The ScanVue420 VF display model has 4 language character sets, ASCII+European

(default), ASCII+Cyrillic, ASCII+Hebrew and ASCII+Katakana that can be changed with a mode command from UnitConfig. The 4 extended language sets are shown in

Appendix D.

There is no display formatting utility or language character conversion capability in this version, so messages (80 characters max including blank spaces) must be padded with spaces to center text or get it to appear as you want on the display. Non standard ASCII characters—this means almost all characters other than English upper and lower case and symbols, must be entered in hex code format.

Network Messages

Three (3) network related customer messages generated within the price verifier can be changed by the user. The default messages are: Checking….. one moment please

(Mode=msgChecking) and Unavailable…..please try later (Mode=msgUnavail) and the

Default text message (Mode=BannerText). Using the UnitConfig program, locate the mode (row) for the message you want to change, highlight the New Content box and enter the new message.

Appendix H—Expanded Text API

With the standard text API, only one font size with a single foreground and background color can be displayed at a time. To support different fonts and colors on the screen at the same time, usually done within defined window areas (known as text boxes), an expanded text API is provided so that multiple text boxes can be defined, positioned and displayed with each text box having its own character property controls (font style, size and colors).

Up to eight (8) text boxes can be placed on the screen similtaneously including the default text box defined in the INI file. Each different font style used must be in a new text box, but each character within a single text box can have a different foreground and background color selected from the 256 colors available on the color palette. Any text box may be defined as “transparent” in which the text in that box will appear to float on top of the screen image or wallpaper with no visible text box background color. The whole text box is transparent not just individual characters.

API Notation

Items in braces { and } are optional. If not explicitly specified, the last value used for that item (the default value) is used. Items in angle brackets < and > are parameter values and are described in the text following.

Defining a Text Box

The following section describes how to define a text box. Up to 8 different text boxes can be defined. Once a text box is defined, it retains its properties until the unit is powered down or it is changed by another text message to that box even if its no longer being displayed.

Except for the default text box in the .INI file, text boxes are created at run-time by an escape sequence. A text box can be changed at any time, which deletes the old box and creates a new one. A text box can contain many different colors but only a single font. If the text box is set to transparent, the whole text box not individual characters within that text box are transparent. Text boxes are identified by an ID # from 0-7.

Text boxes can be created with either trivial or nominal mode packets. Currently, no error reporting is provided.

<ESC>[D<ID>;<Fc>;{<FONT>};{<Fg>}{,<Bg>};{<Cr>}{,<Cc>};{<Ph>}{,<Pv>};{<TO>}; where:

<ID> Text Box ID #, ASCII 0-7. 0 is the .INI default text box

<Fc> Control Function—2 decimal digits, 0-9

00 = mixed text (text over an image)

01 = transparent text

02 = exclusive text



User Manual

M37574–01T


<FONT> The font file (specify in same way as in the .INI file)

<Fg> Foreground text color, ASCII 0-255

<Bg> Background text color, ASCII 0-255

<Cr> Count of text rows

<Cc> Count of text columns

<Ph> Horizontal pixel position of top left corner of box

<Pv> Vertical pixel position of top left corner of box where top left corner of the display is 0,0

<TO> Text timeout

Important note: while the parameters in <> are optional, the semi-colons are not.

For example:

<ESC>[D1;2;fonts/bit16x32.gft;;1,2;16,16;; defines text box 1 with the current default text colors and timeout. Those values come from the default text box (0).

Text Color

The foreground and background colors of each character in a string can be set with the following ESCAPE sequence.

<ESC>[C{<Fg>}{,<Bg>}; where:

C is the character

Fg and Bg are the are the color palette index numbers (0-255) for the foreground and background colors respectively.

If either parameter is omitted, the current values will be used. If this is the first text color control in a message the values will be those specified for the box. If this is not the first text color control in a message, the values set previously will be used.

Example:

The following sequence sets the foreground color of character C to index 5 and the background color to index 253.

<ESC> [ C 5 , 2 5 3 ;

1B h

5B h

43 h

35 h

2C h

Writing to a Text Box

Specify the text box ID # and the text to be displayed

<ESC>[<ID>;{<TEXT>}

The text string can include text color controls. Text sent without a box ID # will be inserted into the default text box, ID=0.

Text Timeout

When sent as part of a text message, causes the current text box to timeout (be removed from the screen). The TO value is the ASCII number of seconds

<ESC>[T<TO>;

Mixed Fonts Example: while a text box can only contain a single font, several transparent text boxes can be placed on top of a non-transparent box to provide the same effect as multiple fonts in a single word. The following example creates three text boxes to display Einstein’s equation E=mc

Appendix J—IEE FTP Site

IEE’s FTP website has the full content of the SDK CD-ROM and software upgrades to the price verifier unit. Any or all of these files can be downloaded to a computer.

The easiest way to reach IEE’s FTP web site is with Microsoft’s IE Explorer. The steps to get to the FTP website are as follows.

1. Using IE Explorer, address to ftp://ftp.ieeinc.com/

2. Verify the correct website is found by checking the blue bar at the top.

3. You should see a single folder called “incoming” or possibly it will be blank.

4. Click on File on the menu bar.

5. In the dropdown menu click Login As…

6. In the window enter User Name: IEEMorse and Password: warcode

This should get you into the FTP site. You will see a number of folders. The upgrade folders for VF and LCD can be downloaded—read all the instructions before you try to upgrade a unit.

The folder called IEE has the complete contents of the SDK CD-ROM. This complete folder or only specific folders or files may be downloaded as you wish.

Appendix K—Running an Open Socket

The price verifier is designed for a socket listener on the host server to open port 1283 from an inquiry from the price verifier and close the port when the request is complete.

A special mode has been implemented that will send keep-alives to the socket at the frequency entered into UnitConfig.

In this mode, the socket is kept open as long as the keep-alives are sent. Other processes can be run between the price verifier and the host that are unrelated to the price verification task.

To keep the socket open: enter any non zero integer (seconds) into the KeepAliveTime mode in UnitConfig. Factory default is socket normal.

Diagnostic Screens and Messages

Version 3.10 and later software has a built in diagnostic that will automatically attempt to determine and resolve network connectivity problems when the unit is powered up. By their very nature diagnostics are not completely fool proof, but they are powerful tools and many times can pin point problems exactly or provide a strong clue to the actual problem. The host must be able to ping the unit for the diagnostics to be meaningful.

Diagnostic screens have a bright red background, with text displayed in yellow on a blue background. The first line of the display will indicate the type of connection being attempted–Windows networking (SMB), FTP, or Quick File Exchange (QFX). The unit will display, at most, one diagnostic screen between restarts. If you have multiple problems they will show up one at a time.

The second line indicates the general class of error, Internal, Connect, or Transfer.

The third line will name the specific error, and if a file name is involved, it will be displayed on the fourth line.

Internal Error

An Internal class error usually relates to a ScanVue5

® device failure and should never be seen. If the unit can be pinged it is working well enough to eliminate device failure as a cause of not connecting.

Transfer Error

Transfer class errors indicate problems with transferring data over the network after a connection has been established to the host. Again, the explanations provided are not necessarily the only possibilities.

Data Transfer The unit is not able to send messages to the host even though it has a valid connection. This can be caused by broken server software or for some protocols, by firewalls between the unit and host.

File Unavailable

No Attribute

The requested file doesn’t exist or security makes it unavailable. This diagnostic message may display even if everything else is working. It indicates a failure to get the

.INI or the slideshow file. This message will display if the files are available but one of the graphics is not. This is generally a recoverable error. For the INI and slideshow files, the unit will get them when they show up; graphic files are bypassed.

This indicates that the Windows server has the file, but cannot provide its size or time stamp. This is a failure on the host or server.



User Manual

M37574–01T


Connect Error

A Connect error is the most likely type to occur. The explanations given may not be the only possible reason for the message.

Connect Fail A general failure to connect to the host. If the host can ping the unit, getting this error should not be possible.

Connect Timeout The initial connection was made but the host has not responded to further communication in timely manner.

Refused

Logon

Protocol Fail

Share Unavailable

Host Resolution

Transfer

The host is there and the unit can connect to it. The host may not have an appropriate server running, or security may otherwise refuse to allow the connection.

The user name and/or password are incorrect.

For Windows networking, the unit and the host could not find a mutually acceptable protocol level.

The directory requested does not exist, or is not shared, or protections prevent the unit from connecting to it.

The specified host name cannot be resolved to an IP address. This can happen if the host name is incorrect or if the host is on another subnet and there is no WINS server available or the WINS server IP has not been set.

This may be a transient error that will not re–occur if you power cycle the unit and try again. Normally you should never see this message, as it indicates a failure of software and/or hardware on the host, the network, or on the unit.

SMB Connect Refused

This can occur in the following the following cases:

1. The share POS directory is not accessable; either because the share does not exist, or user permissions are not set to allow access.

2. The scanvue.ini file may not exist in the share.

3. The share may exist but access may be denied because

“Guest” account is disabled, or the account identified to access this share may not be applied to the permissions
