Notice: Be sure to follow figures two and three when making your own cables. Do not use the
ground lug on the XLR connector. Do not connect the cable's shield conductor to the ground lug or
allow the shield conductor to come into contact with the XLR's outer casing. Grounding the shield
could cause a short circuit and lead to erratic behavior.
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 con-nected 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 reduce the chance 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 cables. 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 electronics stores. The chart below details a proper cable conversion.
