Variable PWM DMX Decoder User Guide
INTRODUCTION
Congratulations on your purchase of a RoscoLED Variable PWM DMX Decoder. Designed for the most demanding lighting
applications, these decoders offer both DMX and Stand-Alone Modes for controlling RoscoLED products – with or without
a DMX console. RoscoLED DMX Decoders also provide lighting professionals the means to vary the Pulse Width
Modulation and Gamma Curve of the unit for complete control of their RoscoLED products.
SAFETY INFORMATION
• Please read this manual before attempting to use your Decoder.
• DO NOT install with power applied to device.
• For indoor use only. DO NOT expose the device to moisture.
MODES OF OPERATION
The RoscoLED PWM DMX Decoder has two modes of operation: DMX Mode and Stand Alone Mode.
Before applying other settings, the Mode of Operation must be set.
To select the desired mode, press the Down button until appears and press the Enter button,
click the Down button again to select 1 or 2, then press the Back button.
: DMX Mode – In this mode DMX from a DMX512 console will be used as the data source for control.
: Stand Alone Mode – In this mode DMX is not required. The on board control panel can be used for dimming
control or preprogrammed effects sequences.
When changing between modes it will be necessary to cycle power to the device (disconnect power and re-energize).

UNDERSTANDING THE DISPLAY IN DMX MODE
A period between the “A” and the following digits indicates the presence of a DMX signal.
Indicates DMX address. The factory default is 001.
Indicates number of output channels. The factory default will match the number of outputs for the hardware.
Indicates 8bit or 16bit mode. The factory default is 16bit.
XXX
XXX
XX
XX
Indicates output PWM frequency (500Hz to 30kHz). The factory default is 1kHz.
Indicates output dimming curve gamma value. The factory default setting is gA1.5.
Indicates Decoding mode. Factory default setting is dP1.1, 1 channel per output.
Indicates the device is set to run1 mode (DMX decoder mode).

CHANGING DMX ADDRESS
Select display option . Press “Enter”. The screen will flash to acknowledge a change can be made.
Press “up” or “down” to select desired value. Press “Back” to save value.
Note: This device has the capability to detect the presence of DMX signal.
This indicator is between the A and following digits A.XXX.
SETTING DMX CHANNEL OUTPUTS
Select display option . Press “Enter”. The screen will flash to acknowledge a change can be made. Press “up” or “down” to
select desired value. Press “Back” to save value. CH01 will assign all outputs to one channel of DMX. CH05/CH12 will assign one
DMX channel to each output. CH05 (5 Channel Model) or CH12 (12 Channel Model).
SETTING BIT MODE FOR PWM OUTPUT
Select display option . Press “Enter”. The screen will flash to acknowledge a change can be made. Press “up” or “down” to
select desired value. Press “Back” to save value. bt08 will offer 8 bit, bt16 will offer 16 bit.
SETTING PWM FREQUENCY
Select display option . Press “Enter”. The screen will flash to acknowledge a change can be made. Press “up” or “down” to
select desired value. 00=500 Hz, 01=1KHZ, 30=30KHZ.

value
Select display option . Press “Enter”.The screen will flash to
acknowledge a change can be made. Press “up” or “down” to select desired
value ranging from 0.1 to 9.9:
Gamma setting = 1 Dimming response is linear
Gamma setting < 1 Dimming curve is exponential with
greater sensitivity at upper end (high output)
Gamma setting > 1 Dimming curve is exponential with
greater sensitivity at lower end (low output)
SETTING DECODER MODE (5 CHANNEL MODEL)
= 1 Channel per output
= 2 Channels per output (coarse, fine). *This function is only available when Gamma value is set lower than 1.4.
= 5 Outputs with Master. In this model channels 1-5 will control individual outputs with channel number 6 as a
master dimming channel.
= 5 Outputs with Master and channel 7 as strobe controls.

SETTING DECODER MODE (12 CHANNEL MODEL)
= 1 Channel Per output
= 2 Channels per output (coarse, fine). *This function is only available when Gamma value is set lower than 1.4.
= Master with 2 channels. This is useful in tunable white LED tapes and panels like RoscoLED Tape VariWhite.
The first channel controls overall intensity, channels 2 and 3 will control the two sets of LED chips.
Ex: Master, warm, cool.
= Master with two combined outputs. In this mode the first channel will act as a master, the second channel will
combine outputs 1 & 3, the second output will combine outputs 2 & 4.
= Master with 3 channels. This is useful in controlling RoscoLED Tape VariColor and panels like Rosco’s LitePad
RGB. The first channel controls overall intensity, channels 2, 3 and 4 will control the two sets of LED chips.
Ex: Master, red, green, blue.
= Master with 3 dimming channels and strobe effects. See table below for strobe values.
= Master with 4 dimming channels. This is useful for RoscoLED Tape VariColor. The first channel controls overall
intensity, channels 2, 3, 4 and 5 control each set of LEDs.
Ex: Master, Red, Green, Blue, White.
= Master with 4 dimming channels and strobe effects. See table below for strobe values.
= Combination of Master with 4 dimming channels followed by Master with two dimming channels. This is good
for when two different types of tape would need to be controlled using the same decoder.
Ex: Master, Red, Green, Blue, White – Master, Warm White, Cool White

Stand Alone Mode:
UNDERSTANDING THE DISPLAY IN STAND ALONE MODE:
In this mode settings can be set using the onboard controls without the presence of a DMX controller. Any values that are set will
generate a DMX signal that can be passed to other decoders using the 5-pin female XLR DMX output.
The first two digits represent the output being controlled. The next two digits represent the dimming level.
Chase Mode. 4 Different Chases Available.
Chase Speed. 9 Different Speeds available.
DIMMING CONTROL
Select display option - (5 Channel Model) or - (12 Channel Model).
The first two digits represent the output channel being controlled. Press “Enter”. The screen will flash to acknowledge a change can
be made. Press “up” or “down” to select desired dimming value from 0-FL (100 steps). Press “Back” to save value.
CHASE MODE
Select display option . Press “Enter”. The screen will flash to acknowledge a chase mode had been engaged. In this model
the screen will stay flashing. Press “up” or “down” to select the desired chase. Pressing “Back” will exit chase mode.
