GLOBOSTAR D4-L 4 Channel Constant Voltage DMX512 and RDM Decoder User Manual

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.

Mechanical Structures and Installations

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.
3. When display OLA, overload alarm. When display OHA, overheat alarm.

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

• 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.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)

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.

Restore factory default parameter

• Long press ◀ and ▶ key for 2s, restore factory default parameter, display”RES”.
• Factory default parameter: DMX decode mode, DMX decode start address is 1, four channel decode, 8 bit grey level, 2000Hz PWM frequence output, logarithmic brightness curve, output 100% level when no DMX input, RGB mode number is 1, dimmer mode number is 1, disable automatic blank screen.

Malfunctions analysis & troubleshooting

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.
