Boom Box FX2 DMX Set Up
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 in contact with the XLR's outer casing. Grounding the shield
could cause a short circuit and 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 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.
