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.
2.5 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.
2.6 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.
2.7 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.
