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 DMX
mode.

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.

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. Automatic blank screen: short press or key to switch enable (“bon”) or disable(“boF”) automatic blank screen. Long press M key for 2s or timeout 10s, quit system parameter setting.

DMX mode Short press M key, when display 001~512, enter DMX mode. Press or key to change DMX decode start address(001~512), long press for fast adjustment. If there is a DMX signal input, will enter DMX mode automatically. DMX Dimming: Each D4-L DMX decoder occupy 4 DMX address when connecting the DMX console.
For example, the defaulted start address is 1, their corresponding relationship in the form:
Stand-alone RGB/RGBW mode Enter stand-alone RGB/RGBW mode only when DMX signal is disconnected or lost. Short press M key, when display P01~P30, enter stand-alone RGB/RGBW mode. Press or key to change dynamic mode number(P01~P30). Each mode can adjust speed and brightness.
Long press M key for 2s, prepare for setup mode speed, brightness, W channel brightness. Short press M key to switch three item. Press or key to setup value of each item. Mode speed: 1-10 level speed(S-1, S-9, S-F). Mode brightness: 1-10 level brightness(b-1, b-9, b-F). W channel brightness: 0-255 level brightness(400-4FF). Long press M key for 2s, or timeout 10s, quit setting.

Malfunctions analysis & troubleshooting

Malfunctions
No light
Wrong color
Uneven intensity between front and rear,with voltage drop

Causes
1. No power. 2. Wrong connection or insecure. 1. Wrong connection of R/G/B/W wires. 2. DMX decode address error.
1. Output cable is too long. 2. Wire diameter is too small. 3. Overload beyond power supply capability. 4. Overload beyond controller capability.

Troubleshooting
1. Check the power. 2. Check the connection. 1. Reconnect R/G/B/W wires. 2. Set corrrect decode address.
1. Reduce cable or loop supply. 2. Change wider wire. 3. Replace higher power supply. 4. Add power repeater.
