OK, so you got the introduction to DMX control above, so at least you know what the basics are. Get a commer-
cial controller, or the inexpensive USB controller above, plug in a daisy-chain of XLR cables to a number of lights
and fixtures that have a standard DMX input, set and map the addresses, and you’re all set! Sounds simple, huh? Well, here’s the next problem! What happens when you want to
control standard incandescent lighting fixtures that don’t have a DMX control? It’s simple, use this simple single channel dimmer!
This little dimmer circuit allows you to control a lamp or group of lamps with your DMX controller. It is designed to dim resistive loads such as incandescent lamps and line operated
halogen lamps (not low voltage halogens!). The controller has a primary power input of 115/230VAC so it can be used with either primary power mains. Likewise, the output fol-
lows the input voltage to power the light(s) you connect.
110VAC input will power 110VAC lights, 230VAC input will power 230VAC fixtures. The maximum resistive load is 1000 watts at 230VAC, or 500W at 115VAC. The dimmer can be
programmed to any of the 512 DMX addresses with a simple dip switch. It also features a status LED for power and DMX error detection, toroidal filtering for low noise, and a stand-
alone test mode. The DMX input is a standard XLR connector. The board measures 5.9” x 2.3” x 1.8”. From Velleman.

At this point some of you may be wondering... “um, what is a DMX interface?” While it’s not something you would find in a typical
home, it’s widely used in stage and music productions. DMX is short for an EIA-485 based communications protocol that is com-
monly used for stage lighting and stage effects. If you ever wondered - how do they control all those stage lights, lasers, and
other effects remotely from a single control point... now you know!
This little controller is USB controlled via a PC or laptop. “DMX Light Player” software is included to give you flexible control of up
to 512 DMX channels, each channel with 256 levels! Now you’re starting to get it! DMX fixtures are connected to the controller via
standard XLR cables. Multiple fixtures are simply “daisy-chained”
together giving you one final connection to the con-
troller.
In addition to the Light Player software, test software is included to test all fixtures and a custom DLL is
also provided allowing you to write your own software. Any PC compatible with USB1.1 is compatible
with the controller. The controller is powered via the USB cable connection, however an
optional 9VDC battery can also be used for stand-alone testing. This is handy when using
the built-in test mode that outputs to all 512 channels with adjustable levels without a USB
connection or external software!
The controller is available as a do-it-yourself kit, or factory assembled and tested ready to operate.
It comes complete with a professional enclosure, USB cable, and installation CD that includes test
software, DLL, and DMX Light Player. If you need to control multiple stage lights and effects that have DMX control, but don’t want to spend a fortune for a commercial controller, this
USB controller fits the bill! Take total control of your lights with DMX! From Velleman.

What if you need to do more than dim a resistive incandescent light in your DMX control chain? What if you need to pro-
vide an on/off function? Just like the dimmer above, if you are switching a device that doesn’t have a standard DMX con-
trol input, you’re pretty much out of luck... unless you have this handy little relay board!
Here’s how it works: First we plug this relay board into the DMX control daisy-chain (or directly to a controller if that’s all you’re controlling). Next, set the dip switches to the desired
DMX address. There can be up to 512 addresses in a single DMX chain, so you’ve got plenty of room to add more devices later! Finally, map that address in your controller, and
you’re now “talking” to the relay switch with the controller, and can enable the on/off function of the relay. It’s that simple!
The switch is actually a bus-controlled power driver. The on-board relay will be activated when the DMX value of the set channel equals 140 or more, and will shut off when the
value is 120 or less. LED indication is provided on the board for power supply and DMX error detection.
In addition, “Safe DMX Data Stream” mode is used to reduce interference. If the DMX signal is lost (i.e. somebody trips on the cable!) the “Relay Hold” function will continue to latch
the relay. DMX input is via a standard XLR connector. Relay switching capacity is 8A. The board runs on any 12VDC unregulated power supply or source. Available as a do-it-yourself
kit or factory assembled & tested for immediate use. Board measures 4.1” x 2.4” x 1.2”. From Velleman.

DMX CONTROL... What is it?
“DMX512 was originally intended as a 'lowest common denominator' protocol for use between interfaces support-
ing proprietary protocols. However, it soon became the primary method for linking not only controllers and dim-
mers, but also more advanced fixtures and special effects devices such as fog machines and moving lights.”
