CHAPTER 4<br />
DMX Programming Basics and Quick Start<br />
Determining a DMX Start Channel<br />
The DMX Start Channel is the first channel of a device’s channel range on a DMX link. There are<br />
512 available channels on each DMX universe divided among all the devices in a particular<br />
universe. A device must have a unique DMX Start Channel number in order to respond<br />
independently to controller commands.<br />
To determine each device’s DMX Start Channel, identify the footprint of every device on the<br />
universe. The device’s footprint is the number of consecutive DMX channels a device requires<br />
and is determined by the channels in the fixture’s protocol. The fixture’s DMX channel range<br />
must not overlap any other device’s channel range on the link. When two devices on the same<br />
DMX universe have overlapping channel ranges, one or both devices will be disabled or behave<br />
erratically.<br />
