Notice:
Be sure to follow figures two and three when making your own
DMX+,DMX-,COMMON
cables. Do not use the ground lug on the XLR connector. Do not con-
nect 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.

used, you may need to use a terminator on the last unit to avoid erratic
behavior. A terminator is a 90-120 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 decrease the possibilities of erratic
behavior.
Termination reduces signal errors and
avoids signal transmission problems

connectors for DATA transmission in place of 3-pin. 5-pin XLR fixtures
may be implemented in a 3-pin XLR DMX line. When inserting standard
5-pin XLR connectors 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.
