SETUP
Power Supply: The ADJ Dotz Par 100 contains an automatic voltage switch, which will automatically
sense the voltage when it is plugged into a power source. With this switch there is no need to worry
about the correct power voltage, and this unit can be plugged in anywhere.
DMX-512: DMX is short for Digital Multiplex. This is a universal protocol used as a form of commu-
nication between intelligent fixtures and controllers. A DMX controller sends DMX data instructions
from the controller to the fixture. DMX data is sent as serial data that travels from fixture to fixture
via the DATA “IN” and DATA “OUT” XLR terminals located on all DMX fixtures (most controllers only
have a DATA “OUT” terminal).
DMX Linking: DMX is a language allowing all makes and models of different manufacturers to be
linked together and operate from a single controller, as long as all fixtures and the controller are DMX
compliant. To ensure proper DMX data transmission, try to use the shortest cable length possible
when linking several DMX fixtures. The order in which fixtures are connected in a DMX line does not
influence the DMX addressing. For example, a fixture assigned a DMX address of 1 may be placed
anywhere in a DMX line: at the beginning, at the end, or anywhere in the middle. When a fixture is
assigned a DMX address of 1, the DMX controller knows to send DATA assigned to address 1 to that
unit, no matter where it is located in the DMX chain.
Data Cable (DMX Cable) Requirements (For DMX Operation): The Dotz Par 100 can be controlled
via DMX-512 protocol. The Dotz Par 100 has 4 DMX Channel Modes. The DMX address is set on the
rear panel of the Dotz Par 100. Your unit and your DMX controller require a approved DMX-512 110
Ohm Data cable for data input and data output (Figure 1). We recommend Accu-Cable DMX cables.
If you are making your own cables, be sure to use standard 110-120 Ohm shielded cable (This cable
may be purchased at almost all professional sound and lighting stores). Your cables should be made
with a male XLR connector at one end and a female XLR connector at the other. Also remember that
DMX cable must be daisy chained and cannot be split.
