Operation

System parameter setting:

• Long press M and key in the same time for 2s, prepare for setup system parameter: output PWM frequency, output brightness curve, grey level, default output level, automatic blank screen.
• Short press M key to switch ve item.
• 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).

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 D1-L DMX decoder occupies 1 DMX address when connecting the DMX console.

Stand-alone dynamic mode:

• Select stand-alone dynamic mode and dimmer mode by pressing the button with built-in programs instead of the DMX signal.

Note:

• An DMX signal amplifier is needed if more than 32 decoders are connected or use an overlong signal line. Signal amplification should not be more than 5 times continuously.
• If the recoil effect occurs because of a 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: output PWM frequence, output brightness curve, grey level, default output level, automatic blank screen. short press M key to switch ve item.
• 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”).
• Grey level: short press ◀ or ▶ key to switch 8bit(“b08”) or 16 bit(“b16”). choose 16 bit if the DMX master support 16 bit.
• 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 D1-L DMX decoder occupy 1 DMX address when connecting the DMX console.

Stand-alone dynamic mode

• Enter stand-alone dynamic mode only when DMX signal is disconnected or lost.
• Short press M key, when display P-1~P-3, enter stand-alone dynamic mode.
• Press ◀ or ▶ key to change dynamic mode number(P-1~P-3).
• Each mode can adjust speed and brightness.
  • Long press M key for 2s, prepare for setup mode speed and brightness. Short press M key to switch two 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).
  • Long press M key for 2s, or timeout 10s, quit setting.

Dynamic mode list

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 brightness independently.

Long press M key for 2s, prepare for setup brightness(b00~bFF). Press ◀ or ▶ key to adjust brightness value. Short press M key, 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, 8 bit grey level, 2000Hz PWM frequence output, logarithmic brightness curve, output 100% level when no DMX input, dimmer mode number is 1, disable automatic blank screen.
