5. Installation
5.1 Fiber Optic Cable Connection
Insert the fiber optic cables into the fiber head opening on the front of the light engine. Ensure the cables are securely fastened. A PG connector (if included) can be used to secure the fiber bundle.
5.2 Power Connection
Connect the provided adapter plug to the 'Power Input' port on the light engine. Then, plug the adapter into a suitable AC power outlet (AC86-265V).
5.3 DMX512 Console Connection (DMX Mode)
To control the light engine via DMX512, connect a DMX512 console or PC DMX512 console to the 'DMX512 IN' port using an XLR cable. If connecting multiple light engines or DMX decoders, use the 'DMX512 OUT' port to daisy-chain them.

Figure 5.1: DMX and RF Model Connection Diagrams. The top section shows how to connect the light engine to a DMX512 console, either directly or through a DMX512 decoder. The bottom section illustrates connecting multiple light engines in an RF control setup (master/slave configuration).
5.4 Built-in Effects Mode Connection
For built-in effects mode, the light engine can operate standalone or in a master/slave configuration. Ensure the DMX address switches are set appropriately (refer to Section 6.3).

Figure 5.2: Built-in Model Connection Diagrams. This image shows how to connect multiple light engines in a master/slave setup for built-in effects, both directly and with DMX512 decoders.
6. Operation
6.1 RF Remote Control Operation
The included 28-key RF remote control allows for easy adjustment of colors, brightness, and dynamic modes.

Figure 6.1: RF Remote Control Instructions. This diagram details the function of each button on the 28-key RF remote, including ON/OFF, color selection, speed/brightness adjustment, jump/fade modes, and DIY settings.
- ON/OFF: Turns the light engine on or off.
- Speed or Brightness +/-: Adjusts brightness in static color mode or speed in dynamic modes.
- Static Color Buttons (RED, GREEN, BLUE, WHITE, YELLOW, CYAN, PURPLE): Selects a single static color.
- Jump Modes (3 Color Jump, 7 Color Jump): Cycles through colors with abrupt transitions.
- Fade Modes (3 Color Fade, 7 Color Fade): Cycles through colors with smooth transitions.
- Flash Jump: A rapid flashing mode.
- DIY Keys (DIY1-DIY5, DIY Jump): Allows users to customize and save specific color and brightness settings.
Match Code Function:
By default, one remote can control multiple light sources. To achieve one-to-one control:
- Power on the LED engine. It will indicate readiness with a red light.
- Within the effective remote distance, simultaneously press the FADE3 and FADE7 buttons. The LED engine's white color will flash, indicating successful code matching.
6.2 DMX Mode Operation
When operating in DMX mode, the light engine accepts DMX512 signals from a DMX console. The DMX address is set using the DIP switches on the unit.

Figure 6.2: DMX Mode and Built-in Effects Settings. This image provides instructions for setting the DMX address using DIP switches and lists the available built-in effects and speed choices.
Setting DMX Address:
- Ensure the 'FUN' switch (the tenth switch) is set to OFF to enable DMX512 signal mode.
- The DMX address is set by the binary numeric code switches (1-9). Switch 1 is the lowest position, and switch 9 is the highest.
- To set a switch to 'ON', push it up. To set it to 'OFF', push it down.
- The DMX512 start address is the sum of the values of switches 1-9 that are set to 'ON'.
DMX Address Examples:
- Example 1 (Address 38): Set switches 6, 3, 2 to 'ON', and others to 'OFF'. The sum is 32 + 4 + 2 = 38.
- Example 2 (Address 388): Set switches 8, 6, 3, 2 to 'ON', and others to 'OFF'. The sum is 256 + 128 + 4 + 2 = 388.
DMX Channel Assignment (3 Channels):
- Channel 1: Red (R)
- Channel 2: Green (G)
- Channel 3: Blue (B)
6.3 Built-in Effects Mode
The light engine has several pre-programmed effects. To activate built-in effects, set the 'FUN' switch (the tenth switch) to ON. The DMX address switches (1-9) can then be used to select specific effects and speeds.
Effect Choices (Button Switch No.1 to No.4):
- Push No.1: Seven-color gradual cycle changing
- Push No.1 & 2: Seven-color jumping
- Push No.1 & 3: RGBW flash jumping
- Push No.1 & 2 & 3: Static green
- Push No.1 & 4: Static yellow
- Push No.1 & 2 & 4: Static cyan
- Push No.2: RGBW Fade in and out
- Push No.3: RGBW jumping
- Push No.2 & 3: Static red
- Push No.4: Static blue
- Push No.2 & 4: Static purple
- Push No.3 & 4: Static white

- Push No.6: 1 second
- Push No.5,6: 1.5 second
- Push No.7: 2 second
- Push No.5,7: 0.5 second
- Push No.6,7: 1 second
- Push No.5,6,7: 1.5 second
- Push No.8: 2 second
