Using the VDO Atomic Dot
Warning! Read 'Safety information' on page 7 before applying power to the VDO
Atomic Dot.
Do not use the VDO Atomic Dot if the ambient temperature exceeds 40° C (104° F)
or falls below 0° C (32° F).
Thermal regulation
The VDO Atomic Dot uses passive cooling without a fan, and controls its temperature by dimming
down automatically if it gets too hot, for example on full white it will dim after about 10 seconds to a
lower intensity. At high ambient temperatures the output will also be reduced.
Video display using P3
The VDO Atomic Dot can display video from all common video sources. The video signal must be
sent to a Martin® P3 controller and then distributed to fixtures. The P3 controller lets you map,
configure and control an installation containing VDO Atomic Dots (and other Martin® P3 video
display products if you have them).
Once the VDO Atomic Dot fixtures are mapped and addressed on the P3 System Controller, it is
possible to map video onto them, while still having control from the lighting desk. At any given
moment the output from the fixture can be controlled by video content, DMX channels, internal
effect macros or a mix.
See the P3 controller documentation for details.
DMX control
The VDO Atomic Dot can display effects controlled by DMX (either using the 5-pin XLR or via Art-
Net / sACN).
Five DMX modes are available:
1 channel mode: uses a single DMX channel and operates the fixture as a white "blinder"
with automatic tungsten fade effect
3 channel mode: gives strobe functionality of intensity / duration / rate, same as Atomic
3000 DMX/LED (no backlight functions)
4 channel mode: As 3 channel mode but with an additional effects channel, same as
Atomic 3000 DMX/LED (no backlight functions)
Basic mode: uses 19 DMX channels and gives RGB color mixing of backlight/aura, strobe
effects and pre-programmed dynamic effects. P3 video data can also be superimposed or
mixed under DMX control.
Extended mode: uses 64 DMX channels to add to Basic mode by allowing individual
control of the 16 LEDs in the backlight/aura. P3 video data can also be superimposed or
mixed under DMX control.
See "DMX protocols" on page 29 for full details of DMX control.
An RDM-compatible DMX controller is required so that you can address and configure the fixtures.
See the DMX/RDM controller documentation for details.
