Facts About The DMX Merger


by Ava Hudson


The right play of lights could help bring focus on different details, whether on architecture, people or objects. It could highlight what is good in one thing and hide the flaws in it. Knowing how to effectively manipulate light would be very useful for various settings such as in photography, architecture and theater. This can help enhance the picture for the viewer. There are lots of ways to have good stage lighting, among them is employing a DMX merger.

DMX mergers are standard for digital communication networks commonly used to control stage lights and effects. They were originally intended for being the standardized method with controlling light dimmers. It is now the primary means with linking special effects devices, controllers and dimmers. It is being used in various platforms ranging from the Christmas lights to the billboards.

The network utilizes multidrop bus topology with nodes that get strung together in daisy chain. It is composed of a controller which serves as the master and slave devices which can be one or more. The controller would have out connector only. Slave devices on the other hand have out and in connectors on them. The out connector from the controller will go to the in connector in the first device then there will be a second cable linking to another out connector for the next device. The last device's out connector will have a terminator that is plugged on it.

Data are sent through EIA 485 voltage levels. Network wiring is composed of a twisted pair that is shielded having a termination resistor to absorb signal reflections. Data link uses five-pin electrical connectors. An eight-pin modular connector may be used too if it is for fixed installations.

For the datalink layer, controllers transmit serial data which is asynchronous. Format is fixed as one start bit, no parity, eight data bits and two stop bits. Start gets signified through a break, signaling an end of one packet, then a mark.

There are several devices, consoles and controllers used in connecting a greater variety of lighting accessories and lighting fixtures. Intelligent lighting would be observed in lots of settings. Theme park utilizes it in many of their attractions and is used as well for many kinds of shows like in fountain displays and others.

This also is widely used now with architectural lighting projects. They get used for illuminating exteriors for buildings, for general use in building management and as accents. High end residential lighting also employs its use. Popularity in LED lighting fixtures made its use abundant in architecture.

There have been developments in this technology including the use of adapters which are wireless. That is useful for architectural lighting because cable lengths can be limited, so wireless operation becomes very desirable. It would make use of transmitters that are wireless on controllers and there would be receivers positioned next to fixtures where wireless signals may be converted into the conventional wired signal.

DMX merger could easily improve aesthetics. This really is useful in various fields. A figure, place or structure would be made much interesting because of it.
