Scantech-ID Shuttle C SG-15 Colour 51
Chapter 5.7 Web Price Checker
Introduction
To make the Shuttle long term future proof the PC55 Colour features the valuable
Web Price Checker application, which is standard on board as of firmware V093.
These are the
Features and Benefits :
• Easy integration of the PC55 in the Retailers IT structure,
using HTML web standards.
• Central Management of PC55 screen content
• Natural and easy use of colours on the PC55 screen
• Built-in Price Check demo on board. Straight from the box.
No configuration required.
The web based price-checker uses a web-kit library to setup a browser-like
connection to an http server. When a bar code is scanned, the PC55
Colour will send
the scanned data as an HTTP request to a web server. The web server is
responsible for generating the HTML page with Article/Price/Picture content,
which is sent to the PC55
Colour . The web-kit utility executing on the PC55 Colour will
interpret and show the content on the display.
1. START PAGE
Default, the URL of the Start Page and Welcome Page are defined as HTML files
residing on the PC55 Colour . The Start page is only displayed at start-up of the Web-
Price-Checker application. Having these files local on the PC55 Colour guarantees
that the PC55 Colour starts with a non-empty page (even if the web-server is
temporary out of service).
2. WELCOME PAGE
The welcome page shown in between barcode scans when the PC55 Colour is in idle
state. The URL may refer to a local file or to an external (web) server.
3. WELCOME TIMER
After a scan and a successful article look-up, the server replies with an article
description, price etc. This information is displayed on the screen for the number
of seconds specified in the
Welcome Timer field. When this timer times out, the
PC55 Colour enters an idle state and normally it will re-display the Welcome Message
