DMX-512 connection with DMX terminator
A DMX terminator should be used in all DMX lines especially in longer runs. The use of a
terminator may avoid erratic behavior in your DMX line. A terminator is a 120 ohm 1/4 watt
resistor that is connected between pins 2 and 3 of a male XLR connector (DATA + and
DATA -). This fixture is inserted in the female XLR connector of the last fixture in your daisy
chain to terminate the line. Using a line terminator (Elation part: DMX T PACK) will decrease
the possibilities of erratic behavior.
5-Pin XLR DMX Connectors. Some manufactures use 5-pin XLR connectors for DATA
transmission in place of 3-pin. 5-pin XLR fixtures may be implemented in a 3-pin XLR DMX
line. When inserting standard 5-pin XLR connectors in to a 3-pin line a cable adaptor must
be used, these adaptors are readily available at most electric stores. The following chart
details a proper cable conversion.
Fixture DMX addressing;
All fixtures should be given a DMX starting address when using a DMX controller, so the
correct fixture responds to the correct control signal. This digital starting address is the
channel number from which the fixture starts to “listen” to the digital control information sent
