CHAPTER 5
DMX Programming Basics and Quick Start
40 DLHD Digital Light User Manual
To determine each device’s DMX Start Channel, identify the footprint of every device on the
universe. The device’s footprint is the number of consecutive DMX channels it requires and is
determined by the channels in the fixture’s protocol. The fixture’s DMX channel footprint must
not overlap any other device’s channel footprint on the link. When two devices on the same DMX
universe have overlapping channel footprints, one or both devices will be disabled or behave
erratically.
Once you have determined the footprint of your device, a simple formula for finding the last valid
Start Channel on a standard DMX512 link is:
512 – the unit’s channel foo 1
Digital Lighting Products
The channel range for your Digital lighting product will depend on the model, the Protocol mode
and the number of Graphic objects you select. DL.3 and Axon media servers running Version 2.0
fixture software all provide individual and composite graphical control for up to nine Graphic
Objects. DL.2 fixtures can control up to four Graphic objects. You can influence the footprint of
the fixture on a DMX link with the protocol you select and the number of graphic objects you
implement.
Select the protocol level in the fixture’s onboard menu system for DLHD, DL.3 and DL.2 fixtures
or through the CMA for Axon HD, Axon and any Digital Light server (see Viewing Server
Configuration on page 276). For a table of channels for Axon HD media server protocol, download
