Terminator specification:
a 120Ωresistor with a power
of 0.25w, solderd between
pin 2 and pin 3 at the end of
respective data link.
Connect the 3-pin output of a lighting controller to the 3-pin input of a first fixture on
the link, then connect the 3-pin output of the said first fixture to the 3-pin input of a
second fixture. Similarly, repeat the above connection step and end the data link with
a plug-in terminator. Shown as Fig. 5.1-2 below.
3-pin XLR connecters are provided for fixture DMX input and output.
Pin 1 is for earthing, pin 2 is for minus signals, and pin 3 is for plus signals.
To prevent and absorb the reflection and interference of the signals, each data link
must be ended by a respective terminator.
Note: The signal cable is type X connection.
Type X connection—if the external flexible cable or cord of this fixture is damaged,
it shall be replaced by a special cord or cord exclusively available from the
manufacturer or his service agent.

If long-distance data transfer occurs, a DMX512 signal amplifier is necessary.
The added amplifier is inserted between the lighting controller and the first
fixture on the basis of a normal data link.
