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.
● 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-P/D4-E 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:
DMX mode
(001~512)
DMX mode
CH1 0-255
CH2 0-255
CH3 0-255
CH4 0-255

DMX Console DMX Decoder Output
CH2 PWM 0-100% (LED G)
CH3 PWM 0-100% (LED B)
CH4 PWM 0-100% (LED W)
Self-test mode
● Enter self-test mode only when DMX signal is disconnected or lost.
● Short press M key, when display L-1~L-5, enter self-test mode.
● Press ◀ or ▶ key to change mode number(L-1L-5).
● Self-test mode include four channel light up separately or synchronously.

Malfunctions analysis & troubleshooting
1. Wrong connection of R/G/B/W wires.
2. DMX decode address error.
Causes
1. Output cable is too long.
2. Wire diameter is too small.
3. Overload beyond power supply capability.
4. Overload beyond controller capability.
1. No power.
2. Wrong connection or insecure.
Wrong color
Malfunctions
Uneven intensity
between front and
rear,with voltage drop
No light
1. Reconnect R/G/B/W wires.
2. Set corrrect decode address.
Troubleshooting
1. Reduce cable or loop supply.
2. Change wider wire.
3. Replace higher power supply.
4. Add power repeater.
1. Check the power.
2. Check the connection.
