Setting up a DMX connection:
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 the DMX connection position can be
positioned 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 the DMX address 1 has been assigned to a device, the DMX controller knows which
addressers the data send filter, 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
DMX channel allocation:
8 DMX channels
