ADJ Startec RAYZER - 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.

Termination reduces signal errors and
avoids signal transmission problems
and interference. It is always advisable
to connect a DMX terminal, (Resistance
120 Ohm 1/4 W) between PIN 2 (DMX-)
and PIN 3 (DMX +) of the last fixture.

5-Pin XLR DMX Connectors. Some manufactures use 5pin DMX-512 data cables for DATA
transmission in place of 3pin. 5pin DMX xtures may be implemented in a 3-pin DMX line. When
inserting standard 5pin data cable in to a 3pin line a cable adaptor must be used, these adaptors are
readily available at most electric stores. The chart below details a proper cable conversion.
