DOCTUS.D
5.5.2.1 Termination Resistor
In DMX RDM connections, the use of a termination resistor is necessary to minimize reflections and provide
good communication.
The value of the termination resistor is 120 Ohm and should be placed near the two ends of the communication
network. Some control units provide a built-in termination resistor.
5.5.3 Connessioni
DOCTUS.D fixtures are provided with an end-stripped 4-pole cable.
The following table allows to match each cable, through its color, with the associated signal

5.5.5 Maximum Distance
If it is necessary to install the product away from the power source and the control unit, consider that:
•
Cable splices and product connections must be made as specified above.
• The maximum distance that can be reached must take into account both the characteristics of the
communication network and those of the power supply.
• Cable junctions must be made as recommended both for correct electrical operation and to maintain
the IP protection rating.
