Use a cable conforming to specifications EIA RS-485: pole twisted, shielded, 120Ohm
characteristic impedance and low capacity (SG DMX3 – SG DMX5).
Do not use microphone cable or other cable with different characteristics than those
specified. Terminations must be made with male / female XLR 3-pin connectors. You must
enter on the last device a terminal plug with a 120Ohm resistance (min 1/4 W) between
terminals 2 and 3.
IMPORTANT: The cables must not come into contact with each other or with the metal
housing of the connectors. The housing itself must be connected to the shield braid and to
pin 1 of the connectors.
