1. Entwodiksyon
This manual provides detailed instructions for the installation, operation, and maintenance of your AMKI 3-Channel DMX512 Decoder. This device is designed to convert universal DMX512 digital signals into PWM signals, allowing it to drive LED lighting products such as RGB LED strips, modules, and other LED fixtures. It features a digital display for easy address setting and mode selection.
2. Enfòmasyon sou Sekirite
- Asire ekipman pou pouvwa a voltage matches the decoder's requirements (DC12V-24V).
- Do not connect the decoder to AC power directly.
- Always disconnect power before making any connections or adjustments.
- Evite ekspoze aparèy la nan imidite oswa tanperati ekstrèm.
- Pa eseye louvri oswa modifye aparèy la, paske sa ap anile garanti a epi li ka lakòz domaj oswa blesi.
- Asire bon vantilasyon pou anpeche surchof.

4.2 Etap Koneksyon
- Koneksyon ekipman pou pouvwa: Connect a DC12V-24V power supply to the "INPUT: DC12V-DC24V" terminals. Ensure correct polarity (V+ to positive, V- to negative). The maximum output current is 3x8A, so ensure your power supply can handle the total load of your LED lights.
- LED Output Connection: Connect your LED lighting products (e.g., RGB LED strips) to the "OUTPUT: CH1, CH2, CH3" terminals. For RGB strips, connect Red to CH1, Green to CH2, Blue to CH3, and the common anode to V+. For single-color lights, connect to any channel. Ensure the total current for each channel does not exceed 8A.
- DMX Signal Input:
- Koneksyon XLR: Connect your DMX controller's output to the "DMX512 IN" XLR port. If daisy-chaining multiple decoders, connect the "DMX512 OUT" of the first decoder to the "DMX512 IN" of the next.
- Koneksyon RJ45: Alternatively, use a Cat5 Ethernet cable to connect your DMX controller to the RJ45 input port. The RJ45 ports are wired for standard DMX pin locations.
- Pouvwa sou: Once all connections are secure, apply power to the decoder. The digital display will illuminate.
5. Operasyon Enstriksyon
The AMKI DMX512 Decoder offers DMX mode and several built-in static/dynamic modes. The digital display and buttons are used for configuration.
5.1 Setting DMX Address (A Mode)
In DMX mode, the decoder responds to DMX signals starting from a specific address. This is the default operating mode.
- When powered on, the display will typically show an 'A' followed by a four-digit number (e.g., A001). This indicates the current DMX start address.
- Peze a SET button to enter address setting mode. The digits will flash.
- Sèvi ak la + epi - buttons to adjust the DMX start address (range A001 to A512).
- Peze a SET button again to confirm and save the address. The display will stop flashing.
- The decoder will now respond to DMX signals on the set address and the subsequent two channels (for a 3-channel device). For example, if set to A001, it will use DMX channels 1, 2, and 3.
5.2 Built-in Modes (H Mode)
The decoder includes pre-programmed static and dynamic lighting effects. These modes disable DMX control.
- From DMX address setting mode (A mode), press the SET button repeatedly until the display shows 'H' followed by a two-digit number (e.g., H-01). This indicates the built-in mode selection.
- Sèvi ak la + epi - buttons to cycle through the available built-in modes (H-01 to H-11). Each mode represents a different static color or dynamic effect.
- Peze a SET button to confirm the selected mode.
5.3 Adjusting Speed/Brightness (S Mode)
For dynamic built-in modes, you can adjust the speed. For static built-in modes, this may adjust brightness.
- While in a built-in mode (H mode), press the SET button again until the display shows 'S' followed by a two-digit number (e.g., S-01). This indicates speed/brightness adjustment.
- Sèvi ak la + epi - buttons to adjust the speed or brightness level (S-01 to S-20).
- Peze a SET bouton pou konfime anviwònman an.
Note: To return to DMX control, you must manually set the device back to 'A' mode and select a DMX address. The device will retain its last setting upon power cycle.
6. Antretyen
- Kenbe aparèy la pwòp epi san pousyè. Sèvi ak yon twal mou epi sèk pou netwaye.
- Asire w ke tout koneksyon an sekirite epi yo pa korozyon.
- Store the device in a dry, cool environment when not in use.
- No user-serviceable parts inside. Refer all servicing to qualified personnel.
