Special Note: Line Termination. When longer runs of cable are used, you may need to use a termina-
tor 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 transmis-
sion 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 adaptor must be used, these adaptors are readily
available at most electric stores. The chart below details a proper cable conversion.
