2.3.3 Control Desk
The control desk uses exclusively sturdy and longlife Lumitas keys. These can be equipped
with either bulbs (factory default) or Multichip-LEDs (option). Please note that the bulbs are
much brighter then the Multichip-LEDs.
For displays, green LED-ASCII-displays are used. Thus, an excellent visibility is provided
also in bad lighting conditions.
The control surface can entirely be configured by the user with several sets of predefined
software functions. You will find a detailed description of the available functions in the
chapter
“Configuration” on page 80
.
On the control desk, there is no special master module, all control desk modules are
working completely independent from each other on the CAN Bus, and all modules are hot
plugable.
