Control
Use the two push buttons on the bottom of the fixture to set the starting address for the
fixture. View the LED display with the push buttons on the left. The top push button
increases the number and the bottom push button decreases the number. Pressing and
holding the push button increases the rate of change. When fixtures are powered up,
they may temporarily respond to DMX address 001 for the first few seconds of
operation. New address settings take effect after the LED display turns off.
C A U T I O N : Do not push the up and down address buttons simultaneously, or internal fixture
software settings can be inadvertently compromised and performance affected.
Up and down address buttons are recessed to avoid inadvertent address changes. Use a
Phillips screwdriver or other blunt device to lightly push the switches. To avoid damaging
the switches, do not use sharp objects or excessive force when changing fixture address.
Addresses must be set between 1 and 505. Selador fixtures are manufactured based on an
11" LED array, or cell. Each cell can be addressed individually. Eleven inch fixtures have
one cell, 21 fixtures have two cells, 42 fixtures have four cells, and 63 fixtures have six cells.
A 42 fixture can be addressed as four individual cells, one cell, or any combination.
Each Selador fixture must be considered a separate DMX device for the purpose of
DMX line-loading calculations, with the exception of 63 fixtures. These 63 fixtures
must each be considered 1.5 DMX devices for line loading.
DMX line-loading practice dictates that no more than 31 devices can be daisy-chained
together. Consequently, no combination of Selador fixtures totaling more than 31 DMX
devices should be configured in one DMX line. For example, twenty 6-cell units (30 DMX
devices) are okay. Twenty-one 6-cell units (31.5 DMX devices) are not acceptable. For runs
of fixtures totaling more than 31 DMX devices, split the DMX runs by using a DMX splitter.
N o t e : A fixture with a starting address higher than 505 will not have control of all parameters.
Therefore, 505 is the highest address shown on the address display.
