Wiring Diagram

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- 120Ω terminal resistor at the end of each DMX signal line.

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-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 Console	DMX Decoder Output
CH1 0-255	CH1 PWM 0-100% (LED R)
CH2 0-255	CH2 PWM 0-100% (LED G)
CH3 0-255	CH3 PWM 0-100% (LED B)
CH4 0-255	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.

Dimming curve setting

• Linear dimming curve
• Logarithmic dimming curve

Malfunctions analysis & troubleshooting

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