Example2
Select Start Addresses for 4 fixtures each requiring 2 channels of DMX.
For this example, start with the first unit set to the first possible Start Address =
1
. This fixture
occupies DMX channels 1 thru 2. The next DMX channel available for a Start Address is found
by adding the previous fixture’s Start Address to its channel requirement: 1+2=
3
. To maximize
channel usage, we will leave no empty channels between fixtures so the second Start Address is
set to DMX channel 3 and that fixture occupies channels 3 thru 4. The third fixture will be
addressed 3+2=
5
and occupy channels 5 thru 6. The last fixture is addressed 5+2=
7
and will
occupy channels 7 thru 8. Thus, 4 fixtures using 2 channels each have Start Addresses of
1, 3,
5
and
7
and the next free channel in the system is 7+2=9.
