Multiple Signal Types
Under certain circumstances the digital control panel can receive two or more
types of input signals.
The output for each dimmer is determined as follows:
1
DMX and Analog- by the highest input signal it is receiving from the
different sources.
2
DMX/Analog and Luma-Net - by the last action input signal it receives
from different sources. e.g. If DMX signal is on and a Luma-Net signal
appears, control is faded from the DMX level to the Luma-Net level. If
DMX level is then changed, control will fade back to and track the DMX
level.
