4 Channel Constant Voltage DMX512 & RDM Decoder
Model No.: D4-L
RDM/Stand-alone function/Seven PWM frequency/Linear or logarithmic dimming/Numeric display
Features
Comply with the DMX512 standard protocols. Digital numeric display, set DMX decode start address by buttons. RDM function can realize intercommunication between DMX master and decoder.
For example, DMX decoder address can be set by DMX master console. 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.

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.
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.

Stand-alone dimmer mode Enter stand-alone dimmer mode only when DMX signal is disconnected or lost. Short press M key, when display L-1~L-8, enter stand-alone dimmer mode.
Press or key to change dimmer mode number(L-1~L-8). Each dimmer mode can adjust each channel brightness independently.
Long press M key for 2s, prepare for setup four channel brightness. Short press M key to switch four channel(100~1FF, 200~2FF, 300~3FF, 400~4FF).
Press or key to setup brightness value of each channel. 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.
