TechnoArc DMX Protocol
The TechnoArc fixture uses 21 channels of a standard DMX512 link to control motion, wheel
functions, zoom, iris, shutter and lamp function.
These parameters are described in the following sections.
Note: All DMX values indicated in the detailed parameter descriptions are in
decimal units.
Pan and Tilt Parameters
The TechnoArc fixture has a 540° pan range and a 245° tilt range. Two DMX channels provide 16-
bit adjustment to a fraction of a degree for pan and tilt position.
Note:
Optical encoders for pan and tilt instantly correct the fixture’s position if the
fixture is jarred from its programmed position. If a physical obstruction
prevents the fixture from correcting its position, the fixture “times out” to
prevent wear on the motors. If the fixture has timed out, remove the
obstruction and home the fixture to return it to normal operation.
