CONNECTION TO THE DMX SIGNAL
The connection of the DMX signal to the XS must be made by using the signal input XLR 5 pin or XLR3 pin connectors which are
located on the rear panel of the XS. (pict.4)
The pin nomenclature of the connectors for the connection to the DMX signal is listed in the table. (pict.4/a)
In order to avoid any problem in the signal transmission, it is warmly suggested to use a cable for high speed data transmission.
The usage of a normal microphonic or audio cable is suggested only for lines max 100 mts long. The best performances are with
microphonic cable of mm2x0.25 + ground or with cable for data transmission. If the lines have a total length over 150-200 mts it is
suggested to use our DMX Repeater Amplifier.

DMX TERMINAL LINE
The wrong connection of the terminal line or its non-connection are probably the most frequent reasons for the defective functioning
of the DMX line. The terminator is a resistor fitted between the two “data” lines (pins 2 and 3 of an XLR 5 or XLR 3 pin connector)
at the end of the cable furthest from the transmitter. The terminator resistor should have the same value as the impedance of the
connection cable.
We supply a terminal with a 100 Ohm resistor.
It is recommanded that all DMX 512 systems have the termination resistor at the and of the line.
