INSTALLATION
SAFETY & WARNINGS
1.Install in accordance with national and local electrical code
regulations.
2.This product is intended to be installed and serviced by a qualified,
licensed electrician.
3.DO NOT connect directly to high voltage power. Install with a
compatible Class 2 constant voltage LED driver (power supply).
4.This product is rated for indoor installation and is not protected
against moisture.
5.Install appropriately rated wire between driver, decoder, and fixture.
When choosing wire, factor in voltage drop, amperage rating, and
type (in-wall rated, etc.) Inadequate wire installation may cause fire.
6.Do not modify or disassemble product beyond instructions or
warranty will be void.

TURN POWER OFF AT CIRCUIT BREAKER
SHOCK HAZARD! May result in serious injury or death.
Turn power OFF at circuit breaker prior to installalation.
MAXIMUM DAISY-CHAIN DMX DECODERS
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.

Use the 3 buttons of the DMX start channel to adjust the values of the
DMX address. The decoder will control up to 512 channels.
a.To set the DMX address, press and hold ‘button 1’ for 2 seconds
until numbers on display flash.
b.Select an address based on the functionality of the Master DMX
Controller (see controller installation guide). Once an address is
selected, the remaining 3 channels will be utilized digitally. For
example, if the decoder is addressed to 001 on the display then
CH1 – 001, CH2 – 002, CH3 – 003, CH4 – 004.
c.Once display stops flashing, DMX address is set.

SETTING PWM FREQUENCY & DIMMING TYPE
The PWM frequency & dimming type can be adjusted for special
applications.
RGB & RGBW SETTINGS
RGB & RGBW installations will only operate correctly with
consistent color output when programmed to P1 (1500Hz PWM
OUTPUT) and c2 (LINEAR DIMMING).
OPERATION (PROFESSIONAL USE ONLY)
Diode LED strongly recommends only professional DMX installers
utilize the following settings. All standard DMX applications specified
by Diode LED do not require these settings to be adjusted.
PWM & DIM (P_c)
SETTING DMX CHANNELS
The DMX channels can be adjusted, which allows the user to conserve
DMX addresses that may be wasted when programming a large DMX
universe.
PWM Output (P)
Dimming Output (c)
1 = 1500Hz
1 = Logarithmic Dimming
2 = 200 Hz
2 = Linear Dimming
The factory default is 4cH: 4 channels (address 001 - 004) as
highlighted in the chart below. Charts have also been provided for
1cH, 2cH, and 3cH settings.

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.

Symptom
Common Cause
• Incorrect wiring. Reversing Data + and Data will cause lights to flicker.
• Incorrect voltage pairing of driver and
Fixture responding

incorrectly and/or
• Ensure compatible constant voltage driver is

installed.
• Check
connections
of

components.
* Driver may not require a fault ground connection. Refer to driver
specifications for additional information.
** Install a compatible Class 2 constant voltage driver. It is recommended
to load the driver no more than 80% its labeled rating for maximum
longevity.
