AC100-240V Power Supply -> 12-24VDC Constant Voltage ->DMX Master -> D4-L DMX512 & RDM Decoder -> RGBW LED strip

Note:

1. An DMX signal amplifier is needed if more than 32 decoders are connected, or use overlong signal line, signal amplification should not be more than 5 times continuously.
2. If the recoil effect occurs because of longer signal line or bad line quality, please try to connect 0.25W 90-120 terminal resistor at the end of each DMX signal line.

Product Usage Instructions

System parameter setting:

1. Long press M and key in the same time for 2s to prepare for setting up system parameters.

2. Short press M key to switch between six items:

1. Decode mode: Use short press or key to switch 1/2/4 channel decode mode (d-1, d-2, or d-4). When set as 1 channel decode, the decoder occupies only 1 DMX address, and the four channels output the same brightness of this DMX address.
2. Grey level: Use short press or key to switch between 8bit (b08) or 16bit (b16). Choose 16bit if the DMX master supports 16bit.
3. Output PWM frequency: Use short press or key to switch between different frequencies: 250Hz (F02), 500Hz (F05), 1000Hz (F10), 2000Hz (F20), 4000Hz (F40), 8000Hz (F80).
4. Output brightness curve: Use short press or key to switch between logarithmic or linear dimming curve.
5. Default output level
6. Automatic blank screen

DMX mode:

1. Short press M key, when display shows 001~512, enter DMXmode.

2. Press or key to change DMX decode start address (001~512), long press for fast adjustment.

3. If there is a DMX signal input, the decoder will enter DMX mode automatically.

4. DMX Dimming: Each D4-L DMX decoder occupies 4 DMX addresses when connecting to the DMX console.

Features

• 1/2/4 DMX channel output selectable.
• 16bit (65536 levels) /8bit (256 levels) grey level selectable.
• PWM frequency 250/500/1000/2000/4000/8000/16000Hz selectable.
• Logarithmic or linear dimming curve selectable.
• Stand-alone RGB/RGBW mode and 4 channel dimmer mode selectable, which be controlled by buttons with built-in programs, instead of DMX signal.
• Over-heat / Short circuit protection, recover automatically.

Operation

System parameter setting

• Long press M and ◀ key in the same time for 2s, prepare for setup system parameter: decode mode, grey level, output PWM frequence, output brightness curve, default output level, automatic blank screen. short press M key to switch six item.
• Decode mode: short press ◀ or ▶ key to switch 1/2/4 channel decode mode(”d-1“,”d-2“ or ”d-4“). When set as 1 channel decode, the decoder occupy only 1 DMX address, and four channel output the same brightness of this DMX address.
• Grey level: short press ◀ or ▶ key to switch 8bit(”b08“) or 16 bit(”b16“). choose 16 bit if the DMX master support 16 bit.
• Output PWM frequency: short press ◀ or ▶ key to switch 250Hz(”F02“), 500Hz(”F05“), 1000Hz(”F10“), 2000Hz(”F20”), 4000Hz(”F40”), 8000Hz(”F80”) or 16000Hz(”F16”). Higher PWM frequency, will cause lower output current, higher power noise, but more suitable for camera(No ?ickers for video).
• Output brightness curve: short press ◀ or ▶ key to switch linear curve(”C-L“) or logarithmic curve(”C-E“).
• Default output level: press ◀ or ▶ key to change default 0-100% level (”d00“ to ”dFF“ ) when no DMX input signal.
