send DATA assigned to address 1 to that fixture, no matter where it is located
in the DMX chain.
2.4 Data Cable (DMX Cable) Requirements (For DMX and Master/Slave Operation):
The
POWER SPOT 700™
can be controlled via DMX-512 protocol. The
POWER
SPOT 700™
is a 21 channel DMX fixture. The DMX address is set electronically
using the controls on the side panel of the fixture. Your fixture and your DMX
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.

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.
