StudioPix™ Pixelation Luminaire User Manual

The DMX Start Channel is the first channel of a device’s channel range on a DMX link. There are 
512 available channels on each DMX universe divided among all the devices in a particular 
universe. A device must have a unique DMX Start Channel number in order to respond 
independently to controller commands. 

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 a device requires 
and is determined by the channels in the fixture’s protocol. The fixture’s DMX channel range 
must not overlap any other device’s channel range on the link. When two devices on the same 
DMX universe have overlapping channel ranges, one or both devices will be disabled or behave 
erratically. 

Select the protocol level in the fixture’s onboard menu system. The tables on the following 
pages list the parameters included in each protocol mode.
