3-Pin to 3-Pin Cable
Notice: 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 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.
3-Pin to 5-Pin Cable Adapter
Some manufactures use 5-pin DMX- 512 data cables for DATA transmission 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 graphic and chart below detail a proper cable conversion.
