3.0 Hardware Overview
3.1 Interface Connectors
3.1.1 RF In / Out
SMA-F
3.1.2 I/O
A USB type A connector provides both power and serial communications.
4.0 Software Overview
The software is a simple graphical user interface (GUI) that controls operator level functions of the VMT.
4.1 System Requirements
The application has been tested on, Windows XP SP3. For other operating systems suitable drivers may
have to be found or created.
Note. The 64-bit edition of Microsoft Windows Vista only accepts digitally signed driver installation files.
The driver files in this software package are not signed and will not be accepted. They can however be
used on 32-bit edition of Windows Vista.
4.2 Software Installation
A typical windows installation wizard that prompts the user for required input controls the software
installation. After the installation of the GUI application, a USB driver must also be installed.
4.2.1 GUI Application Installation
The setup utility is located in the SW folder on the root directory (Figure 2) of the removable disk.

Double click the setup icon. The utility will start with an initialization screen (Figure 3).
Figure 3 - Location of Setup Utility and Initialization Screen
The utility checks that Microsoft .NET Framework 2.0 is installed on the computer. This framework is a
prerequisite for the installation of the application software. If the Framework is not found, the utility will
begin installation of the framework. The first part of that installation is the Microsoft end user license
agreement (EULA). Accept the agreement to start the installation (Figure 4).
