DMX is a standardized transmission protocol that allows all DMX-compliant models of the various
manufacturers to be connected to one another and controlled by a single mixer. Free DMX data
transfer between different DMX devices are used.
The connection arrangement between the devices has no influence on the DMX addressing. For
example, DMX address 1 has been assigned to a device and it can be positioned at any point of the
DMX connection, at the beginning, at the end or anywhere in the middle.
Therefore the first device, which is controlled by a controller, can be the last one in a row at the
same time. When DMX address 1 has been assigned to a device, the DMX controller knows to which
address the data transfer must take place, no matter where the DMX cable is located.
Resistance 120 ohms 1 / 4w between PIN 2DMX -) and PIN 3 (DMX +) of the last headlight.
Attention: Avoid the contact between the general and the housing grounding of the headlight. The
general grounding may cause a loop and your headlight could only function irregularly. Test the
cables with a resistance meter to check the correct polarity and to ensure the correct polarity.
Connect the headlights:
If you want to control light shows with one or more devices with a DMX-512 controller, or you want
to play synchronized shows with two or more devices in master / slave mode, you must use a serial
data transmission line. The total number of channels required by all devices determines the number
of devices that the data transmission line can support.
The devices connected to a serial data transmission line must be connected in series. According to
the standard EIA-485, no more than 30 devices should be connected to a data transmission line.
However, if you connect more than 30 devices to a serial data transfer line without using an optical
splitter, the quality of the DMX signal may be degraded.
• Maximum recommended length of the DMX data transmission line: 100m
• Maximum recommended number of headlights on a DMX data transmission
line: 30 devices
• With 220V: Up to 6 devices can be connected in series
