2. V-MUX
What is it?
The Weldon V-MUX is a central control system utilized by the new Rosenbauer engines to manage and control the electrical system on the apparatus and provide a centralized place for the operator to activate and deactivate most of the electrical components on the apparatus.
The screen is located adjacent to the driver’s seat and will sometimes also be referred to as the Vista Display.
Most of the normal chassis operations can be found on one of several screens displayed on the V-MUX.
