4.4 User Interface Demo
The WJM Demo Software is freely available to the public:
• WJM Demo – runs on PCs with Microsoft Windows 98, ME, 2000 or XP
The demo software uses the Microsoft .NET Framework, which must also be
installed for the demo installation programs (files with an .msi extension) to run.
Please visit the website for the latest version of this software that will support
newer operating systems.
4.4.1 Installation
Execute the file WJM_Demo_Installer.exe and follow the onscreen instructions.
If you do not have .NET Framework installed, the installation program will prompt
you to install it. This is necessary for the demo software to function.
Please check the WJ Communications website for the latest version.
When upgrading the firmware of your reader, please upgrade the PC
Demo.
4.5 Application Programmers Interface (API)
The WJM is controlled using commands issued to the WJM from a host. Each
command is formatted to control specific elements and options. The API
specification is available on the WJ website that specifies all commands with
explanation of the format. Please refer to the applications notes section of the
WJ website for WJM Host Protocol API.
4.5.1 .NET DLL (Dynamic Link Library)
This library provides a series of methods that allow developers to call the high-
level functions of the WJM-series PC-card readers without being concerned
about low-level packet construction and processing. Compatibility has been
verified for Windows XP and may work with other Windows operating systems.
The original source code, written in C# for the .NET Framework and Compact
Framework, and a compiled library ready for linking to your code are both
provided. For more information, please refer to the application notes section of
the WJ website in Introduction to the WJM DLL.
