CONTROL INPUT BEHAVIORS
All XTR-compatible fixtures use solely DMX as their native control method. If DALI or
0-10V/1-10V control inputs are applied to the XTR Driver then their single dimming value
will be internally converted into an equivalent value across all 512 DMX channels and
duplicated across all of the output feeds: two outputs on the 4000 model and four outputs
on the 8000 model.
[Fixtures with white emitters only] If no control protocol is present, white light fixtures will
default to full on.
Once power has been applied, you need to use the front panel menu to choose the control
input method being used: DMX, DALI, 0-10V (source) or 1-10V (sink). See page 15 for
details.
XTR FIXTURE ADDRESSING
RDM signals are passed transparently across all XTR Driver ports so that individual fixtures
can be uniquely addressed. Various third party DMX/RDM tools are available; Acclaim Lighting
recommends the XMT-350. Please refer to the user guide(s) of your particular XTR fixtures (and
RDM tool) for further details about RDM addressing.
DMX/RDM
When a DMX input is applied to the XTR Driver, it is duplicated across all of the fixtures on all
of the output feeds. Multichannel XTR fixtures can be fully controlled.
DALI
When a DALI input is applied to the XTR Driver, it must use broadcast mode so that one
channel controls all fixtures equally. Therefore only single channel XTR fixtures can be used.
0-10V / 1-10V
When a 0-10V (source) or 1-10V (sink) input is applied to the XTR Driver, it will control all
fixtures equally. Therefore only single channel XTR fixtures can be used.
0-10V (AND 1-10V): CURRENT SOURCE AND CURRENT SINK
There are two arrangements of 0-10V analog control: current source (labeled on the XTR
Driver as 0-10V) and current sink (labeled on the XTR Driver as 1-10V). Current source was
commonly used for theatrical dimming prior to the advent of digital techniques, such as
DMX. Current sink is most often used in architectural/commercial settings. The primary
difference between the two schemes lies with where the control voltage is generated:
•current source (0-10V) requires the controlling device to provide (source) the control
voltage,
•current sink (1-10V) mandates that the controlled fixture (ie the XTR Driver) must
provide the voltage.
The XTR Driver can accept either current source (0-10V) or current sink (1-10V) inputs.
