Termination reduces signal errors and to
avoid signal transmission problems and
interference, it is always advisable to
connect a DMX signal terminator.

DMX Primer
There are 512 channels in a DMX-512 connection. Channels may be assigned in any manner. A fixture
capable of receiving DMX 512 will require one or a number of sequential channels. The user must assign a
starting address on the fixture that indicates the first channel reserved in the controller. There are many
different types of DMX controllable fixtures and they all may vary in the total number of channels required.
Choosing a start address should be planned in advance. Channels should never overlap. If they do, this will
result in erratic operation of the fixtures whose starting address is set incorrectly. You can however, control
multiple fixtures of the same type using the same starting address as long as the intended result is that of
unison movement or operation. In other words, the fixtures will be slaved together and all respond exactly
the same.
DMX fixtures are designed to receive data through a serial Daisy Chain. A Daisy Chain connection is where
the DATA OUT of one fixture connects to the DATA IN of the next fixture. The order in which the fixtures are
connected is not important and has no effect on how a controller communicates to each fixture. Use an
order that provides for the easiest and most direct cabling. Connect fixtures using shielded two conductor
twisted pair cable with three pin XLR male to female connectors. The shield connection is pin 1, while pin 2
is Data Negative (S-) and pin 3 is Data positive (S+). CHAUVET carries 3-pin XLR DMX compliant cables,
DMX-10 (33’), DMX-4.5 (15’) and DMX-1.5 (5’)

Note! If you use a controller with a 5 pin DMX output connector, you will need to use a 5
pin to 3 pin adapter. Chauvet Model No: DMX5M.
