controller require a standard 3-pin XLR connector for data input and data output
(Figure Below). If you are making your own cables, be sure to use standard two
conductor shielded cable (This cable may be purchased at almost all professional
sound and lighting stores). Your cables should be made with a male and female
XLR connector on either end of the cable. Also remember that DMX cable must be
daisy chained and can not be split.
2.6 Notice: Be sure to follow the above figure 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.
2.7 Special Note: Line Termination. When longer runs of cable are used, you may
need to use a terminator on the last fixture to avoid erratic behavior. A terminator
is a 90-120 ohm 1/4 watt resistor which is connected between pins 2 and 3 of a
male XLR connector (DATA + and DATA -). This fixture is inserted in the female
XLR connector of the last fixture 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.
2.8 5-Pin XLR DMX Connectors. Some manufactures use 5-pin XLR 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.
