4. Installation

4.1 Mechanical Structures

Mechanical Structures and Installations with dimensions — Figure 3: Mechanical dimensions of the D12A unit (246mm x 116mm x 38.5mm).

4.2 Wiring Diagram

Ensure all connections are secure and correctly polarized. Refer to the diagram below for proper wiring of the DMX signal, power supply, and LED strips.

Wiring Diagram for DMX signal and RGB LED strips — Figure 4: Wiring diagram for D12A connecting to power supply, DMX master, and RGB LED strips.

Wiring Notes:

Connecting with green terminal (DMX AMP) or an extra amplifier will be needed when more than 32 decoders are connected, or when using overlong signal lines. Signal amplification should not exceed 5 times continuously.
If recoil effect occurs due to longer signal lines or poor line quality, connect a 0.25W 90-120Ω terminal resistor at the end of each DMX signal line.
The D12A can control 1 to 4 groups of RGB LED strips/modules.
It can also control 1 to 4 groups of single color LED strips/modules.

5. Operation

5.1 OLED Screen Interface

OLED screen interface and operation details — Figure 5: OLED screen interface and control buttons.

Button Functions:

Short press MODE key: Switches between DMX decoder mode, Dimmer mode, and RGB controller mode.
Short press SETUP key: Enters parameter setting state and switches between multiple parameter items.
Press < or > key: Adjusts parameters.
Long press SETUP key (or wait 30s): Quits parameter setting state.
Long press M & > key for 2s: Enters fast self-testing.
Long press < & > key for 2s: Restores factory default parameters.

5.2 DMX Decoder Mode

DMX decode start address: 001~512
DMX decode mode: DIM (1CH single color), CCT (2CH color temperature), RGB (3CH)
Output PWM frequency:
- Std (2KHz)
- High (8KHz): Higher PWM frequency, lower output current, higher power noise.
- Mid (500Hz)
- Supr (16KHz): More suitable for camera (no flickers for video).
Grey level: 8bit or 16bit (choose if the DMX master supports 16 bit).
Output dimming curve (Only valid for 8bit Grey level):
- Standard (Gamma 1.6)
- Linear
- Gamma 0.1-9.9: Recommended to use standard. 0.1-9.9 is for special requirements; long press < or > key to change.

5.3 DMX Master Mode as 12 Channel Dimmer

Each channel brightness setting: 0-255 (0-100%).
Use <&> keys to switch between previous or next page, each page displays 3 channels.

5.4 DMX Master Mode as RGB Controller

Dynamic RGB mode: 10 kinds.
Mode speed: 1-10 level (level 10 is fastest).
Mode brightness: 10%-100%.
