link without a DMX splitter will eventually deteriorate 
the digital signal. 

The fixture’s channel range must not overlap any other device’s 
channel range on the link.  When two devices on the same DMX link 
have overlapping channel ranges, one or both devices will be disabled 
or behave erratically.   

The single exception to the non-overlapping rule is if the 
fixtures are the same type (for example two 
Technobeams set to iris protocol) and share the entire 
channel range.

Determining the Unique DMX Start Channel

The DMX start channel is the first channel available to a fixture in its 
channel range.  To determine each fixture’s DMX start channel in a link, 
you must know the number of DMX channels used by each fixture (see 
“Fixture Types” on page 2-13).

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 Table 2-2, 18 (channels used by the 
Technobeam set to iris protocol) + 1 (DMX start channel for the first 
fixture) = 19 (DMX start channel for the next fixture on the link).

*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.

To assign a unique DMX start channel for the fixture:
