ENGLISH VERSION
• Connect the controller DMX input to the DMX
output of the first unit.
• Connect the DMX output to the DMX input of
the following unit. Connect again the output to the
input of the following unit until all the units are
connected in chain.
• When the signal cable has to run longer distance
is recommended to insert a DMX termination on
the last unit.
CONSTRUCTION OF THE DMX TERMINATION
The termination avoids the risk of DMX 512 signals being
reflected back along the cable when they reaches the end
of the line: under certain conditions and with certain cable
lengths, this could cause them to cancel the original signals.
The termination is prepared by soldering a 120Ω 1/4 W re-
sistor between pins 2 and 3 of the 5-pin male XLR connec-
tor, as shown in figure.
