DMX SETUP
SPECIAL NOTE: LINE TERMINATION
When longer runs of cable are used, you may need to use a terminator on the last unit to avoid erratic
behavior. A terminator is a 110-120 ohm 1/4 watt resistor, which is connected between pins 2 and 3 of a
male XLR connector (DATA + and DATA -). This unit is inserted in the female XLR connector of the last
unit in your daisy chain to terminate the line. Using a cable terminator (ADJ part number Z-DMX/T) will
decrease the possibilities of erratic behavior.
5-Pin XLR DMX Connectors. Some manufactures use 5-pin DMX-512 data cables for DATA transmission
in place of 3-pin. 5-pin DMX fixtures may be implemented in a 3-pin DMX line. When inserting standard
5-pin data cables in to a 3-pin line a cable adapter must be used, these adapters are readily available
at most electric stores. The chart below details a proper cable conversion.

DMX ADDRESSING
All fixtures should be given a DMX starting address when using a DMX controller, so the correct fixture
responds to the correct control signal. This digital starting address is the channel number from which
the fixture starts to “listen” to the digital control signal sent out from the DMX controller. The assignment
of this starting DMX address is achieved by setting the correct DMX address on the digital control
display on the fixture.
You can set the same starting address for all fixtures or a group of fixtures, or set different addresses for
each individual fixture. Setting all fixtures to the same DMX address will cause all fixtures to react in the
same way, in other words, changing the settings of one channel will affect all the fixtures simultaneously.
If you set each fixture to a different DMX address, each unit will start to “listen” to the channel number
you have set, based on the quantity of DMX channels of each fixture. That means changing the settings
of one channel will only affect the selected fixture.
In the case of the Focus Spot 4Z/Focus Spot 4Z Pearl, when in 16 channel mode you should set the
starting DMX address of the first unit to 1, the second unit to 17 (16 + 1), the third unit to 33 (17 + 16),
and so on. (See the chart below for more details.)
