ADJ FOCUS PROFILE - DMX Signal Management; Line Termination for DMX Signals; 5-Pin XLR to 3-Pin XLR DMX Conversion

Special Note: Line Termination. When longer runs of cable are used, you may need to use a ter-
minator 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 manufacturers use 5-pin DMX-512 data cables for DATA trans-
mission in place of 3-pin. 5-pin DMX xtures may be implemented in a 3-pin DMX line. When insert-
ing standard 5-pin data cables into a 3-pin line, a cable adaptor must be used. These adaptors are
readily available at most electronics stores. The chart below details a proper cable conversion.
