DMX 512
Connect machines using shielded 2-conductor twisted pair cable with 3-pin XLR
male to female connectors. The shield connection is pin 1, while pin 2 is Data Nega-
tive (S-), and pin 3 is Data positive (S+).
CAUTION: Wires must not come into contact with each other; otherwise the fix -
tures will not work at all, or will not work properly.

DMX Terminator
DMX is a resilient communication protocol, however errors still
occasionally occur. In order to prevent electrical noise from dis-
turbing and corrupting the DMX control signals, a good habit is to
connect DMX output of last fixture in the chain to a DMX termina-
tor, especially over long signal cable runs.
The DMX terminator is simply an XLR connector with a 120Ω
(ohm), 1/4 Watt resistor connected across Signal (-) and Signal (+),
respectively, pins 2 and 3, which is then plugged into the output
socket on last projector in the chain. The connections are illustrat-
ed below.
Complimentary signal cable can transmits signals to 20 unit fixtures at most.
Signal amplifier is a must to connect more fixtures.
5.5. 3-Pin vs 5-Pin DMX cables
DMX connection protocols used by controllers and fixtures manufacturers are not
standardized around the world. However, two are the most common standards:
5-Pin XLR and 3-Pin XLR system. If you wish to connect this fixture to a 5-Pin XLR in-
put fixture, you need to use an adapter-cable or make it by yourself. Below you can
see the wiring correspondence between 3-Pin and 5-Pin plug and socket standards
