DMX 512 DECODERS FOR LED LIGHTING
A DMX decoder is a device that converts a DMX signal to PWM. This will let you control your LED lighting such as LED tape and other lighting products from a DMX controller such as a stage lighting desk or a DMX wall panel.
DMX or digital multiplex can be installed on your computer or laptop in the form of a program to control your DMX devices.
The DMX decoder should be connected to a power supply to power it and also any product such as LED tape that is connected to it.
In DMX, the number 512 corresponds to the number of DMX channels that are available on a DMX device. A single colour LED strip will take up one DMX address, an RGBW colour changing tape will take up four DMX addresses, one address for each colour.
A DMX 512 Decoder setup is easy, the units have an interface that can be in the form of dip switches or control buttons and a digital display.
Other DMX lighting fixtures can be connected to a decoder and some lighting products have built-in DMX decoders so do not need separate decoders.
The number of DMX channels that a decoder will need depends on the number of channels that your lighting needs. The largest DMX decoder that we supply is a 24 channel LED DMX decoder.
Some decoders are also RDM compatible. RDM decoders settings can be adjusted from a DMX512 RDM controller. RDM or Remote Device Management allows two-way protocols from the device to the controller.
What is a DMX Decoder?
A DMX decoder is a lighting control product used to decode a DMX control signal supplied by a controller. The decoder sits between an LED driver and the lighting product it is powering to control its output.
Once the signal is received the decoder will then translate it and alter the PWM frequency of relevant colour channels. By altering the PWM frequency the decoder is able to control colour and brightness of lighting products. By assigning a DMX address to a decoder each device can be found and controlled individually or together.
