SPECIFICATION SHEET
OVERVIEW
The DMX 4-Channel Decoder is a key component used for pairing low
voltage LED tape lights and fixtures with a DMX controller. It works by
translating a DMX signal sent from the DMX controller into a PWM signal
used to dim or control LED lights.
This DMX Decoder features a digital display that is much easier to work
with than traditional dip-switches, as well as a screw-down terminal
block for secure wiring connections. When used with our DMX Splitter,
there is virtually no limit to the number of color-changing LED tape lights
or fixtures required for your installation.
FEATURES & BENEFITS
• Compatible with most DMX controls
• Easy to use Digital Display (no dip-switches)
• Connect multiple units in series with standard CAT5 cable
• UL Recognized Component. File # E484300
APPROVED LED LUMINAIRES
Compatible with all Diode LED 12V and 24VDC constant voltage tape
lights and fixtures.

1. Ensure to specify a compatible driver and fixture with the same voltage specifications. Multiple decoders may be connected to a compatible LED driver with a single output.
2. A maximum of 10x DMX Decoders may be connected together via RJ45 DMX Connection Ports. DMX signal may be extended further by installing a DMX 8-Way Splitter (DI-1804)
after the 10th DMX Decoder.
3. Do not install product in an environment outside the listed ambient temperature. Exceeding the maximum ambient temperature may damage the controller and/or fixture.
4. Operating temperature is measured according to the minimum and maximum ambient temperature environment.

SYSTEM DIAGRAM
The following diagram is provided as an example system design. CAT5 (RJ45 connections) data cables are the most cost-effective solution for transmitting
DMX-512 signals. XLR-3 cables may also be installed but require an additional adapter for connecting to DMX decoders.

Consumer’s Acknowledgment
Diode LED stands behind its products when they are used properly
and according to our specifications. By purchasing our products, the
purchaser agrees and acknowledges that lighting design, configuration
and installation is a complex process, wherein seemingly minor factors
or changes in layout and infield adjustments can have a significant
impact on an entire system. Choosing the correct components is
essential. Diode LED is able to work with the original purchaser to make
an appropriate product selection to the extent of the limited information
that the customer can provide, but it is virtually impossible for Diode
LED to design a system that foresees every unknown factor. For this
reason, this Warranty does not cover problems caused by improper
design, configuration or installation issues. Any statement from a Diode
LED employee or agent regarding a customer’s bill of goods and/or
purchase order is NOT an acknowledgment that the products purchased
are designed and configured correctly. The purchase agrees and
acknowledges that it is the customer’s responsibility to adhere strictly
to all information contained in the Product Specification Sheets.
There is often more than one way to design, configure and layout an
LED lighting application properly to achieve the same lighting effect.
Diode LED strongly recommends that licensed professionals be used
in the design and installation of lighting systems that include Diode
LED products. The specifications include important information that
a designer and installer should carefully review and strictly follow.
Qualified designers and certified and/or licensed installers, with access
to the final installation environment, customer goals, and Diode LED
product specifications can make the requisite decisions appropriate for
a successful finished lighting application.
