DMX decoder address can be set by DMX master console.

  • PWM frequency 2000/500Hz
  • Logarithmic or linear dimming curve
  • Stand-alone 24ch RGB mode and 24 channel dimmer mode selectable, whichbe controlled by buttons with built-in programs, instead of DMX setting.

System parameter setting

  • Long press M and ◀ key for 2s, prepare for setup system parameter: decode mode,

output PWM frequence, output brightness curve, automatic blank screen.

short press M key to switch four item.

  • Decode mode: short press ◀ or ▶ key to switch 1-channel decode(“d–1”), 3-channeldecode(“d–3”) ,

6-channel decode(“d–6”) or 24-channel decode(“d-24”).When set as 1 channel decode,

the decoder occupy only 1 DMX address, and 24 channel output the same brightness of this DMX address.

  • Output PWM frequence: short press ◀ or ▶ key to switch 500Hz(“F–L”) or 2KHz(“F–H”). Higher PWM frequency,

will cause lower output current, higher power noise, but more suitable for camera(No flflickers for video).

  • Output brightness curve: short press ◀ or ▶ key to switch linear curve(“C–L”) or logarithmic curve(“C–E”).
  • Automatic blank screen: short press ◀ or ▶ key to switch enable (“bon”) or disable(“boFF”)

automatic blank screen.

  • Long press M key for 2s or timeout 10s, quit system parameter setting.

DMX mode

  • Short press M key, when display A001~2048, enter DMX mode.
  • Press ◀ or ▶ key to change DMX decode start address(001~2048),
long press for fast adjustment.
  • If there is a DMX signal input, will enter DMX mode automatically.
  • DMX Dimming: Each D24 DMX decoder occupy 24 DMX address
when connecting the DMX console.For example, the defaulted start address is 1,their corresponding relationship in the form:

DMX mode


DMX Console DMX Decoder Output
CH1 0-255 CH1 PWM 0-100% (LED 1#R)
CH2 0-255 CH2 PWM 0-100% (LED 1#G)
CH3 0-255 CH3 PWM 0-100% (LED 1#B)
: :
CH24 0-255 CH12 PWM 0-100% (LED 4#B)

Stand-alone RGB mode

  • Short press M key, when display P–1~P–4, enter stand-alone RGB mode.
  • Press ◀ or ▶ key to change dynamic mode number(P–1~P–4).
  • Each mode can adjust speed and brightness.

Long press M key for 2s, prepare for setup mode speed, brightness.

Short press M key to switch two item.

Press ◀ or ▶ key to setup value of each item.

Mode speed : 1-10 level speed(SP-1, SP-9, SP-F).

Mode brightness: 1-10 level brightness(br-1, br-9, br-F).

Long press M key for 2s, or timeout 10s, quit setting.

  • Enter stand-alone RGB mode only when DMX signal is disconnected or lost.

Stand-alone dimmer mode

  • Short press M key, when display L–1~L–8, enter stand-alone dimmermode.
  • Press ◀ or ▶ key to change dimmer modenumber(L–1~L–8).
  • Each dimmer mode can adjust each channel brightness independently. Longpress M key for 2s, prepare for setup 24 channel brightness.

Short press M key to switch 24 channel(0100~01FF, 0200~02FF, 0300~03FF, … , 2400~24FF),.

Press ◀ or ▶ key to setup brightness value of each channel. Long press M key for 2s, or timeout 10s, quit setting.

  • Enterstand-alone dimmer mode only when DMX signal is disconnected or lost.

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, 24 channel decode,

low PWM frequence output, logarithmic brightness curve, RGB mode number is 1,

dimmer mode number is 1, disable automatic blank screen.
