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.

D4-P, D4-E 4 Channel Constant Voltage DMX512 & RDM Decoder
Operation
DMX mode
● Short press M key, when display 001~999, enter DMX mode.
● Press ◀ or ▶ key to change DMX decode start address(001~999),
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
(001~999)
DMX Console
CH1 0-255
CH2 0-255
CH3 0-255
CH4 0-255
DMX Decoder Output
CH1 PWM 0-100% (LED R)
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
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.
