3. RFgen Sales Strategy • Differentiate offering from other vendors • Provide a “single source” solution • Let customers “try before they buy” • Listen and respond quickly to customer needs • Focus on and sell the right solution

4. RFgen Screen Mapping Easy to Manage:Once connected, data collection terminals can have their own host session (one to one) or share sessions from a pool of open connections. Interaction with the host system is accomplished through a number of easy to use language extensions built into the RFgen VB environment. Using these commands, remote users can send and receive text, keystrokes, call macros, and generally perform any action that a local user could do.

5. Advantages of Screen Mapping With the RFgen Screen Mapping feature, you do not need to be concerned with cross platform compatibility or re-engineering the system’s business rules. RFgen provides easy to use VBA extensions that allow dynamic interaction with the host’s terminal screens, entering remote data collection transactions while the host handles all of the business rules. This process is accomplished with easy “point and click” and “drag and drop” development methods.

6. Three Levels of Integration RFGen provides three levels of integration capability for the user. They are as follows… Basic Also known as “Traditional Screen Mapping”, the user has complete control over the host session. All host interaction scripts are written and maintained by the user. Simplified This method takes a “System” approach to Screen Mapping by providing built-in “recording capabilities” to navigate host menus and update host screens. Embedded This method builds upon Simplified Screen Mapping by allowing users to embed host transaction fields directly into RFGen forms.

7. Session Startup and Shutdown RFGen Screen Mapping was designed to simplify the entire process of interacting with legacy host systems. Accordingly, RFGen allows users to record initial startup and shutdown macros to login and logout of the host system properly. While these macros are called automatically at session startup and shutdown, users can execute these macros whenever they are required.

8. Multiple Host Support RFGen Screen Mapping allows users to connect to multiple host systems. At system startup, RFGen selects the first defined host to be the default host. Screen Mapping commands are automatically directed to that host, or optionally, to any of the others.

9. Screen Mapping Overview RFgen employs the concept of a base screen or “main menu”. The main menu is used as a point-of-reference when moving between different host applications. The methodology is as follows… • A “Main Menu” is identified for a specific linked host. • “Application Screens” are then linked to this main menu. • “Transaction” fields are identified for each application screen. • Remote data entry “transactions” are automatically routed to and entered into the appropriate host screen.

10. Application Screens To create an “Application Screen”, simply follow these 5 easy steps… • Go to the Application Screen – RFGen records all the keystrokes necessary to move from the main menu to the application screen. • Identify the Application Screen – Select the areas of the screen that will uniquely identify this as the application screen (page 1). • Identify Multiple Screen Pages – Select the areas of the screen that uniquely identify an additional page for the application screen. • Return to the Main Menu– RFGen records the keystrokes necessary to move from the application screen back to the main menu. • Test Macros – Indicates success or failure of the macros.

11. Transaction Fields/Macros RFGen uses a concept called “transaction mapping” to interact with legacy host systems. Transaction mapping works as follows… • The user identifies (marks)all important data fields and screen regions. • The user enters a sample transaction which is recorded and converted into a series of commands (macro). • The sample transaction is tested against the host system. Users can call transaction macros, passing them the transaction data and have the macro post the data to the host screen. Optionally, a user can “embed” screen data fields directly into RFGen forms and have the data automatically post to the host once all input fields have been entered. Note: Unlike “Screen Scraping” solutions, RFGen transactions can be used while the host is off-line. These transactions can also comprise multiple host systems or even access ODBC databases.

12. “Embedded” Screen Mapping “Embedded” screen mapping builds on RFgen’s standard (simplified) methodology of creating user interfaces for wireless data collection devices. Using embedded methods, screen mapping applications can be created entirely with “point-and-click” and “drag and drop” techniques.
