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 xtures 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 xtures should be given a DMX starting address when using a DMX controller, so the correct xture

responds to the correct control signal. This digital starting address is the channel number from which

the xture 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 xture.

You can set the same starting address for all xtures or a group of xtures, or set different addresses for

each individual xture. Setting all xtures to the same DMX address will cause all xtures to react in the

same way, in other words, changing the settings of one channel will affect all the xtures simultaneously.

If you set each xture 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 xture. That means changing the settings

of one channel will only affect the selected xture.

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 rst 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.)

Channel Mode Unit 1 Address Unit 2 Address Unit 3 Address Unit 4 Address

16 Channels 1 17 33 49

18 Channels 1 19 37 55

22 Channels 1 23 45 67
