7 DMX basics and addressing
This chapter contains basic information about data transmission via DMX protocol and data for
addressing the spotlights.
DMX signals are generated by a DMX controller and transmitted to the connected devices
using a DMX cable. Up to 512 channels per connection can be transmitted, with a value
between 0 and 255 is transmitted for each channel. The 512 channels form a so-called ‘DMX
universe’.
DMX devices are wired in series, i.e., a transmitting unit sends out signals to all connected
receivers. The receiver arrangement in the device chain can be chosen arbitrarily, since all
devices lter and process the relevant data independently.
To form a serial device chain, the DMX input of the rst receiver is to be connected to the DMX
output of the controller or other DMX master unit. The output of the rst receiver then has to
be connected to the input of the second and so on. The output of the last receiver in a DMX
chain must be terminated with a resistor (110 Ω, ¼ W).
