Determining the DMX Start Channel

This section describes how to determine start channels for the fixtures on a DMX link if you plan
to mix different fixture types (for example, a Studio Command fixture and a Studio Spot 250
fixture) on the same DMX link.
To determine each fixture's DMX start channel in a link, you must know the number of channels
used by each fixture. Knowing that the first fixture on the link will use DMX start channel 1, you
can determine the DMX start channel for each successive fixture by adding the number of DMX
channels used by the fixture to the fixture's DMX start channel. For example, in the following
table, 14 (channels used by Studio Command running) + 1 (DMX start channel for the first
fixture) = 14 (DMX start channel for the next fixture on the link).
Fixture
location on
the link
First Studio Command 1200/700
Second Other Fixture
Third Studio Command -H
Fourth Dimmer required for Studio Command-H
Note: The fixture location on the link does not have to comply with this
example. The fixtures can be addressed in any order on the link. The
maximum Start channel for the last Studio Command fixture on a
DMX512 link is 498 (channel range 498-512).
Note: If you connect more than 32 fixtures to a link, you must use a DMX
splitter. The 32 device limit complies with the EIA-485 standard.
Connecting more than 32 devices per link without a DMX splitter will
eventually deteriorate the digital signal.
