Dmx Set Up - ADJ VF Snow Flurry HO User Manual

DMX SET UP

Power Supply: Before plugging your unit in, be sure the source voltage in your area matches the
required voltage for your device. The VF Snow Flurry HO is available in 120v and 220v versions.
Because line voltage may vary from venue to venue, it is important to verify that your unit voltage
matches the wall outlet voltage before attempting to operate your fixture.
DMX-512: DMX is short for Digital Multiplex. This is a universal protocol used by most lighting and
controller manufacturers as a form of communication 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 locat-
ed 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 path 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. Therefore, the first
fixture controlled by the controller could be the last fixture in the chain. 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): This device can be controlled via
DMX-512 protocol, and it is a 1 channel DMX unit. The DMX address is set using the dipswitches on
the rear panel of the unit. Your unit and your DMX controller require approved DMX-512 110 Ohm
Data cables 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, which 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.
