Architecture

There are two ways to describe the 7802 Terminal System. The first is “Physical” architecture, that is the

way the parts of the system actually hook together; and the second is the “Logical” architecture which

describes the information flow between the parts of the system.

Physical

The 7802 Terminals always connect to a wireless access point to become part of a LAN. In order for the

Terminal to have Internet access, the LAN that it connects to must provide it.

A web-based Connection Host always runs on a web server that supports PHP scripting and MySQL

database. Typically this would be on your web site host's server and set up as part of your web site; or it can

be installed on a web server that is part of your LAN. A typical web server is Apache or IIS with appropriate

PHP and MySQL modules.

Setting up your own web-based Connection Host requires basic knowledge of web server and PHP script

installation.

You can also use the web-based Connection Host provided by Worth Data (terminal's default configuration

is set for this) but be aware this is a shared non-customizable resource intended for demonstration (not

production) and Worth Data makes no guaranties about availability or up-time.

Another possibility is to use the Windows-based Connection Host program provided with your Terminal.

This software is a Windows program that you install and run on a Windows computer attached to your LAN.

It is essentially a custom web server designed specifically to function as a local LAN-based Connection

Host for your Terminals with no Internet connectivity or access required; your LAN is used as a private

“internet”.
