Led Controller Leave a comment 836 Views

1. Comply with the DMX512 standard protocols.


2. Digital numeric display, set DMX decode start address by buttons.


3. RDM function can realize intercommunication between DMX master and decoder.
For example, DMX decoder address can be set by DMX master console.


4. 1/2/4 DMX channel output selectable.


5. 16bit (65536 levels) /8bit (256 levels) grey level selectable.


6. PWM frequency 0.25/0.5/1.0/2.0/4.0/8.0/16.0 KHz selectable.


7. 8A X 4 CH, Max 32 A.


8. Logarithmic or linear dimming curve selectable.


9. Over-heat / Over-load / Short circuit protection, recover automatically.


10. Support 2 kinds of DMX ports with signal isolation function: Green terminal DMX signal ports, RJ-45 DMX signal ports

4 CH DMX512 & RDM Decoder

Operation:

System parameter setting:

  1. 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.
  2. 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.
  3. Grey level: short press ◀ or ▶ key to switch 8bit(“b08") or 16 bit(“b16"). choose 16 bit if the DMX master support 16 bit.
  4. Output PWM frequency: short press ◀ or ▶ key to switch 0.25KHz(“F02"), 0.5KHz(“F05"), 1.0KHz(“F10"), 2.0KHz(“F20"), 4.0KHz(“F40"), 8.0KHz(“F80") or16.0KHz(“F16"). Higher PWM frequency, will cause lower output current, higher power noise, but more suitable for camera(No flickers for video).
  5. Output brightness curve: short press ◀ or ▶ key to switch linear curve(“C-L") or logarithmic curve(“C-E").
  6. Default output level: press ◀ or ▶ key to change default 0-100% level (“d00" to “dFF" ) when no DMX input signal.
  7. Automatic blank screen: short press ◀ or ▶ key to switch enable (“bon") or disable(“boF") automatic blank screen.
  8. Long press M key for 2s or timeout 10s, quit system parameter setting.

DMX mode: 

  1. Short press M key, when display 001~512, enter DMX mode.
  2. Press ◀ or ▶ key to change DMX decode start address(001~512), long press for fast adjustment.
  3. 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:

  1. Enter self-test mode only when DMX signal is disconnected or lost.
  2. Short press M key, when display L-1~L-5, enter self-test mode.
  3. Press ◀ or ▶ key to change mode number(L-1L-5).
  4. Self-test mode include four channel light up separately or synchronously.
