Determining a DMX Start Channel
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.
