U‐Hub
Working Offline
Before we move on to look at adding elements to projects it is important to understand the difference between working off line
and normal on‐line operation at an event. When working off line the Palette allows you to drop elements into the System
Diagram, you can open arrays, speakers, U‐Hubs and Merlins as you would for an on‐line system. This is useful as a means to get
used to system operation in Vu‐Net but very little beyond that. Unlike some systems you CANNOT create a system design off line
and connect to a system on site. When connecting to a system you have to use Device Discovery which searches all available
connected devices for system elements and automatically drops them into the system diagram showing their Ethernet and Vu‐
Net Connections. This is vital as every Vu‐Net element has a unique factory set IP address which Vu‐Net records, so it can provide
real‐time monitoring of the system and can display the status of every device. If for example you re‐connect to a system having
used it on one day and shut down over night, Vu‐Net will be able to detect that every cabinet has been turned back on and the
status of all parameters of every DSP. We will show how to introduce all available elements into a project off line but will cover
Device Discovery and on‐line operation in a later chapter.
Adding U‐Hub
Adding any devices to a System diagram is a simple case of clicking on the required item in the Palette; ‐
Then click on the System Diagram workspace. The cursor will have a small white box with a cross in the centre prompting you to
click where you wish to deposit the device. Here we see a new U‐Hub added to a project; ‐
The four black squares in the corners indicate that the device is still selected which is the default when a new element is added
to a project. The most useful thing about this is that it gives you the opportunity to move it to exactly where you need it simply
by using a click‐drag‐drop movement. A click anywhere else in Vu‐Net will de‐select the U‐Hub.
Any other decide can be added to the project window in the same way.
Device Discovery
The normal method for operating a system following completing the system rigging and connection is to run Vu‐Net is to run
Device Discovery. It is good practice to check your network connectivity, first by using the network icon on the PC task bar which
should show connection to your system (it will flag that there is no internet connectivity which can be ignored). Then by going
