Note:

An DMX signal amplifier is needed if more than 32 decoders are connected, or use overlong signal line is used, 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 a 0.25W 90-120Ω terminal resistor at the end of each DMX signal line.
When display 1OL,2OL,3OL,4OL, correspond to 1,2,3,4 channel overload alarm.
When displaying OHA, the overheat alarm.

Operation

System parameter setting

Long-press M and ◀ key in the same time for 2s, prepare for the setup system parameter: decode mode, grey level, output PWM frequency, output brightness curve, default output level, and automatic blank screen. 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 1-channel decode, the decoder occupies only 1 DMX address, and four channels 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 supports 16-bit.
Output PWM frequency: short press ◀ or ▶ key to switch 250Hz(“F02”), 500Hz(“F05”), 1000Hz(“F10”), 2000Hz(“F20”), 4000Hz(“F40”), 8000Hz(“F80”), 16000Hz(“F16”) or 32000Hz(“F32”).

Higher PWM frequency will cause lower output current, higher power noise, but more suitable for camera(No ickers for video).
When PWM frequency > 8000Hz, it is necessary to reduce the output current per channel (4x3A@12-48V at 16000Hz; 4×2.5A@12-24V and 4x2A@36-48V at 32000Hz)

Output brightness curve: short-press press ◀ or ▶ key to switch linear curve(“C-L”) or the logarithmic curve(“C-E”).
Default output level: set the output level when no DMX input signal. short press ◀ or ▶ key to switch maintain DMX output(“d- -“) or output default level (“d00” to “dFF”, 0-100%), long press ◀ or ▶ key to change output default level.

Automatic blank screen: short-press 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.

Note: In addition to manual button operation settings, the above system parameters can also be set by RDM function.

DMX mode

Press M key when the display shows 001~512, enter DMX mode.

Press ◀ or ▶ key to change the 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 DMX decoder occupies 4 DMX addresses when connecting the DMX console.
For example, the default 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)

Stand-alone RGB/RGBW mode

Enter stand-alone RGB/RGBW mode only when DMX signal is disconnected or lost.
Press M key when the display shows P01~P30, enter stand-alone RGB/RGBW mode.
Press ◀ or ▶ key to change the 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 between three items.
- Press ◀ or ▶ key to setthe 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 the DMX signal is disconnected or lost.
Short press M key short, when the display shows L-1~L-8, enter stand-alone dimmer mode.
Press ◀ or ▶ key to change the dimmer mode number(L-1~L-8).
Each dimmer mode can adjust each channel’s brightness independently.
- Long press M key for 2s, prepare for setup four the four-channel brightness.
- Short press M key to switch four channels (100~1FF, 200~2FF, 300~3FF, 400~4FF).
- Press ◀ or ▶ key to set the 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 parameters, and 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.

FAQ

Do I need a DMX signal amplifier?

An DMX signal amplifier is needed if more than 32 decoders are connected or if an overlong signal line is used. Signal amplification should not exceed 5 times continuously.

How do I address channel overload alarms?

If you see displays like 1OL, 2OL, 3OL, or 4OL, they correspond to 1, 2, 3, or 4 channel overload alarms respectively. When OHA is displayed, it indicates an overheat alarm.

What should I do for recoil effects?

If recoil effects occur due to a longer signal line or poor line quality, try connecting a 0.25W 90-120 terminal resistor at the end of each DMX signal line.
