If a channel is set to “NonDim” then the Min and Max settings are not available and any Min
or Max settings that may have been made are ignored.
Each parameter setting is described below and on screen “Help” also explains each
parameter.
4.9.1 Min Level
“Min” sets the level of the channel output when the control signal is set to minimum. For
example, setting this value slightly above zero is useful to “Pre-Heat” lamp filaments.
4.9.2 Max Level
“Max” sets the level of the dimmer output when its control signal is set to maximum. For
example, setting this value to 90% will extend the life of a lamp as it never operates on full
voltage or setting it to 50% provides 115volt output
4.9.3 Curve
Fade Curve is the curve or “transfer characteristic” between input control signal and dimmer
output. The following curves are available;
 S Law
 Non Dim
When a channel is set to “Non Dim”, the channel will switch from OFF to full ON when the
control signal is raised above 60% and when the level drops below 40%, the channel will
switch OFF. “Non Dim” is used for devices that do not fade, but need to be switched OFF or
ON such as motors or discharge lamps. Min and Max level are not available when Non Dim
is selected.
4.9.4 Source
The Redback channels can be individually configured to be controlled by either:
 DMX only. When configured for “DMX Only” a channel is controlled from a DMX
lighting controller.
 Memory only. When configured for “Memory Only” a channel is controlled from wall
plates that are used to recall memories (6) stored in the Redback dimmer. These
memories can also be recalled from the LCD touch screen.
 Auto Switch. Whenever a valid DMX signal is connected to the Redback, channels
set to “Auto Switch” will be automatically switched from Memory control to DMX
control. When the DMX signal is lost, they will automatically revert to Memory
control.
 Auto Power. Channels configured for “Auto Power” are used to provide power to
non-dimmable fixtures whenever the lighting controller is switched on (and hence a
DMX signal is detected on the input to the Redback). When “Auto Power” is enabled,
channels configured for “Auto Power” will be automatically switched ON at full level
whenever any valid DMX signal is detected. These channels will remain on for a
programmable “hold time” when DMX is no longer detected.
LSC recommends that fixtures requiring non-dimmed power should always be
connected to Redback channels fitted with the “Switch” output option. See section
1.4.2 for details.
