2.1. Running the DataHub Program

To run the DataHub program, select it using the Windows Start menu, or double click the DataHub shortcut icon.

Once started, the DataHub program opens the Properties window:

It also puts an icon in the system tray. If you right-click on the icon, you will get a menu with several options, explained below:

[Note]

Touch-screen users: press the DataHub icon for about one second. When you release, the pop-up menu will appear.

The pop-up menu also lets you exit the DataHub program.

[Note]

It is possible to start a DataHub instance using command-line options. Please refer to Appendix 1, Command Line Options for more information.

Pop-up Help

You can get pop-up help in many parts of the Properties window by right-clicking the mouse over buttons or text.

Exit

You can terminate a DataHub instance by right-clicking the DataHub icon in the system tray, and selecting Exit from the pop-up menu. After a few seconds the icon should disappear, indicating that the DataHub instance has terminated.

[Note]

You must explicitly exit a DataHub instance to terminate it. Otherwise it continues to run in the background even if you close the Properties, Data Browser, and Event Log windows.
