3.10 CONNECTION OF THE DMX LINE
DMX connection employs standard XLR connectors. Use shielded pair-twisted cables with 120Ω imped-
ance and low capacity.
The following diagram shows the connection mode:
ATTENTION
The screened parts of the cable (sleeve) must never be connected to the system’s earth, as this would
For those connections the use of balanced microphone cable is not recommended because it cannot
transmit control DMX data reliably.
• 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.
3.11 CONSTRUCTION OF THE DMX TERMINATION
es 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 resistor between pins 2 and 3 of the 5-pin male XLR
