MATRIX GUIDE v1
3
If the light source is to be used
without an ICELED controller the
red wire must be connected via a
switch to a
fused
power
supply
as shown to the left. The green
wire should connect to the negative
or chassis return for the battery.
Wiring for stand-alone use
In stand-alone mode the unused blue wire must be left unconnected. It is advisable
to tape over the end of the wire or cut it back flush with the outer cable sheath.
Stand-alone operation
If ICELED data is present when the device is powered-up it will produce the colours
commanded by the controller. If no data is present when the power is applied,
MATRIX will start running an internal programme designed to provide as much
functionality as possible with only the interruption of the supply voltage as a control
system.
The built-in stand-alone programme runs through the four phases labelled A to D in
the following diagrams:
Phase Description
A
Rapid fade-up to peak intensity white after connection to the power source
B
Hold on peak white
C
Gentle transition from peak white to the colour change phase
D
Colour phasing - cycles seamlessly through the visible spectrum until power
disconnected
Freezing the colour
At any time, the programme may be halted by briefly
switching the power supply off then back on again (within less than a second). This
simple action allows the light source to be frozen on any particular colour (or white)
