4. DMX STARTING ADDRESS SETTING
The demultiplexer codes 128 subsequent DMX channels, starting with the defined starting
address. The address setting is made with the buttons, described in the further part of the present
manual. As the DMX signal contains control data for 512 channels, when the starting address is
set above 384, the decoded channels number is reduced with reference to available 128. When
the starting address is being tried to be set as higher than 512 it will be corrected automatically.

The frequent cause of a seeming malfunction of the DMX devices is their improper connection in
a DMX installation. The DMX protocol strictly defines the rules of creating a control installation -
below is a scheme of a proper demultiplexer incorporation into a DMX installation.
3. RULES OF CREATING THE DMX INSTALLATION
The demultiplexer incorporation into a DMX control route is realized with the DMX input and
output sockets placed on the device's front panel (adequately described XLR-3 plug and socket).
If the demultiplexer is the last device in a DMX chain, the terminator must be connected to its DMX
output. If the DMX route contains more than 32 receivers or its phisical length exceeds 500
meters you need to use the DMX signal amplifiers (DMX repeaters).
TERMINATOR = 90 - 120 Ohm resistor at the output
of the last receiver in a route (connected to DMX+ and DMX- pins)
DMX ROUTE - 32 receivers max.
