NEBULA OPERATION 5
DMX address number may be chosen to be any number between 1 and 4096 to ease the task of calculating dimmer numbers
in multiple DMX universe systems.
DMX Disable
DMX Start or Patch modes may be switched on or off. If both are off the Nebula then ignores all DMX control levels.
DMX Fail Modes
The Nebula provides two options in case the DMX signal fails, or the DMX signal is turned off, as for example when the
control panel is turned off at the end of a show. The options are
Fade to blackout
- after a delay time, the dimmer levels are faded to blackout. Both the delay time and the fade time are
programmable from Instant to 30 minutes.
Hold last DMX levels
- the last valid DMX levels are held until the next valid DMX input, or the pack is switched off
REMOTE CONTROL
The dimmers of the Nebula may also be controlled by RS-485 signal when fitted with the appropriate software. In this case
the Remote LED indicates that the Nebula is set to respond to remote control from wall-plates or computer.
DIMMER PARAMETERS
The dimmer channels in the Nebula have a number of parameters which may be set individually for each dimmer. As
incorrect setting of these parameters can prevent the Nebula from working as expected, care must be taken when setting them
up.
Test and Set Dimmer levels
Normally each dimmer receives control from the DMX line or RS-485 control where fitted. However the Test/Set options
allow each dimmer to be set to a level which overrides the input from these sources. This override level can be set to any level
between Off and Full. An "All" function allows all Test/Set levels to be faded up or down at the same time. Each dimmer can
also be flashed instantly to Full for identification. The "All" function may also be used with Flash, allowing all dimmers to be
flashed to Full at the same time.
The Test functions are of use during set-up to help check lamps or wiring problems without the use of a control panel. The
Set function is also useful where lights such as orchestra or working lights must be left on permanently.
Minimum and Maximum Dimmer levels
Each dimmer may be set to its own minimum level, and its own maximum level. The "All" function allows all minimum or all
maximum levels to be set at the same time.
