DMX-512 control connection.
Connect the 3 pin XLR cable to the DMX controller and then to the first
Elektric Eye
in the daisy chain. Doing it
this way round avoids the pain of rewiring, if you get the wrong end of the cable back at the controller.
Continue wiring from one
Elektric Eye
to the next fixture in a daisy chain manner. Never try to Y split cables.
Never try to “star wire” a DMX cable run. It will not work.
If additional cable needs to be made up then two-core cable with a screen needs to be purchased. For wiring
please see the diagram below.
DMX has a maximum running distance of 330 feet. When long distances are involved then there is a tendency
for electrical noise to be evident. In which case, a DMX terminator will be required. The terminator helps
prevent corruption of the DMX signal. To make a DMX terminator, simply solder a 120 ohm resistor across pins
2 and 3 of an XLR male connector. Then place that connector at the very end of the DMX cable run. In other
words at the last
Elektric Eye.

It maybe the case that you will need to connect a 5 pin XLR to the 3 pin XLR. In a normal DMX wiring
configuration, the 5 pin is soldered identically to the 3 pin. So in the 5 pin
1: Ground
2: Signal (-)
3: Signal (+)
Pins 4 and 5 are not used. Be very sure you read the pin numbering on the connector when you solder up the
connector. Do not just wire up the three pins to the left or right because the male and female connector has the
pins on different “sides” of the connector! Read the pin numbers.
