Using the VDO Dotron
Warning! Read “Safety information” on page 6 and “Precautions to avoid damage” on page 10 on
before applying power to the VDO Dotron.
Do not use the VDO Dotron if the ambient temperature exceeds 55° C (131° F) or falls below -20° C (-4° F).
Thermal regulation
The VDO Dotron dot has a protective thermal shutdown feature that blacks out the dot if it exceeds its
permitted maximum operating temperature.
To avoid unexpected blackouts due to thermal shutdowns but also avoid overheating that may damage the
product, the VDO Dotron offers various options for managing temperature:
• During P3 video operation, you can enable the thermal regulation feature available in the software of all
Martin® P3 system controllers. When this feature is active, VDO Dotron dots begin to reduce their light
output when the ambient temperature reaches 45° C in order to control dot temperature. Output is
reduced gradually as the ambient temperature rises above 45° C. Dots will still light at the maximum
ambient temperature of 55° C, but output will be considerably reduced. This option avoids blackouts due
to protective thermal shutdowns.
• During P3 video operation, you can disable the P3 controller thermal regulation feature. If you choose to
do this, VDO Dotron dots will not reduce their light output when the ambient temperature reaches 45° C,
but if you drive dots hard when the ambient temperature approaches or exceeds 55° C, dots may black
out completely due to protective thermal shutdown.
• During DMX operation, the VDO Dotron dots begin to reduce their light output when the ambient
temperature reaches 45° C in order to control dot temperature. Output is reduced gradually as the
ambient temperature rises above 45° C. Dots will still light at the maximum ambient temperature of 55° C,
but output will be considerably reduced. This option avoids blackouts due to protective thermal
shutdowns.
P3 display
The VDO Dotron can display video from all common video sources. The video signal must be sent to a
Martin® P3 controller and then distributed to dots. The P3 controller lets you map, configure and control an
installation containing VDO Dotron dots (and other Martin® P3 video display products if you have them).
See the P3 controller documentation for details.
DMX control
The VDO Dotron can display effects controlled by DMX. Three DMX modes are available:
• RGB mode uses three DMX channels and gives RGB color mixing of all the pixels on a dot.
• Basic mode uses ten DMX channels and gives RGB color mixing, strobe effects and pre-programmed
dynamic effects.
See “DMX protocols” on page 31 for full details of DMX control.
An RDM-compatible DMX controller is required so that you can address and configure the dots. See the
DMX/RDM controller documentation for details.
