Application Scenarios
How to Control & Use This DMX Decoder
- Power Connection: Connect a compatible DC 12V-24V LED power supply to the V+ and V- input terminals, ensuring the voltage matches your LED lights.
- DMX Signal Input: Wire the DMX signal cable from your DMX master controller into the DMX IN terminals.
- Lighting Output: Connect your constant voltage single color LED strip lights to the CH1 output terminals. For analog fixtures, use the dedicated 0-10V or 10V PWM outputs.
- Set DMX Address: Use the DIP switches on the decoder to set the starting DMX address. The configuration for each address is detailed in the DMX512 decoder manual.
- Test System: Power on the decoder and power supply. Use your DMX console to send commands to the assigned address and verify smooth dimming control.
- Always ensure the input voltage of the decoder and the operating voltage of your LED lights are the same (12V or 24V).
- Do not exceed the maximum rated load of 12A. Calculate your total load to prevent overheating and damage.
- Verify correct polarity (+/-) for all power and LED connections.
- For detailed wiring diagrams and address settings, please consult the product datasheet available in the Downloads section below.

Frequently Asked Questions
Q: What makes the LT-811-12A DMX decoder unique?
A:Its primary advantage is the combination of a high 12A single-channel capacity with three different signal outputs (CV PWM, 0-10V, 10V PWM), making it exceptionally versatile for many types of fixtures.
Q: Can I use this decoder for RGB or RGBW LED strips?
A:No, this is a single-channel (1CH) decoder designed specifically for single-color lights. For multi-color control, you need a 3-channel (RGB) or 4-channel (RGBW) DMX decoder.
Q: What kind of power supply is required?
A:You need a constant voltage DC 12V or 24V LED power supply. Ensure its wattage rating is sufficient for the total load of your connected lights, not exceeding 144W at 12V or 288W at 24V.
Q: What is the purpose of the 0-10V output?
A:The 0-10V output allows the decoder to control drivers and fixtures that use the 0-10V analog dimming standard, enabling you to integrate them into a modern DMX system.
Q: Is this compatible with any DMX controller?
A:Yes, the LT-811-12A conforms to the standard DMX512 protocol, ensuring it works seamlessly with most professional DMX master controllers, consoles, and software.
