Product Information
The Subordinate New Brand Constant Voltage DMX512 & RDM
Decoder, Model No.: D5-CX, is a versatile device that allows for
easy control and management of LED lighting systems. It is designed
to comply with the DMX512 standard protocol and supports RDM
functionality. With various optional features such as adjustable
PWM frequency, dimming curve options, and protective functions,
this decoder provides a reliable and flexible solution for your
lighting needs.
Features:
- Accord with DMX512 standard protocol.
- Digital Display: Allows for easy configuration and setup.
- Supports RDM function: Enables bidirectional communication
between the decoder and the controller. - Optional Output PWM Frequency: Choose between 2000 Hz or 500 Hz
for optimal performance. - Optional Dimming Curve: Select between logarithmic or linear
dimming for desired lighting effects. - Anti-reverse protection function: Safeguards against reverse
polarity connection. - Short circuit and overcurrent protection: Ensures the safety of
the connected devices. - Self-testing protection function: Automatically tests the
system upon power-on to detect any issues.

Product Usage Instructions
1. Digital Display Status Description:
The digital display provides status information about the
decoder. Here are the different status indications:
- Self-locking: The display locks when there is no operation for
30 seconds. - Unlock: Long press the “M” button for 2 seconds to make the
digital display high light and exit the self-locking state. - Address always ON: Indicates that the DMX signal is valid.
- Address flickering: Indicates that the DMX signal is
invalid. - Err: Indicates a short circuit/overcurrent protection issue,
which will automatically recover after 10 seconds.
2. DMX Initial Address Setting:
To set the DMX initial address, follow these steps:
- Under unlock status, observe the digital display showing
“001-512” (e.g., “001”). - Press the “M” button to change the DMX initial address. Long
press for quick address change. - For example, set the initial address to 100. The D5-CX decoder
will occupy 5 addresses (100-104).
3. System Parameter Setting Instruction:
To adjust system parameters, follow these steps:
- Under unlock status, long press the “M” button for 3 seconds to
enter the system parameter setting mode. - The digital display will show either
“<1>” or “<2>“. - Short press the “M” button to switch between 4 different
parameter settings. - Parameter 1: PWM frequency setting
(“<1>” shows 2000 Hz,
“<2>” shows 500 Hz). - Parameter 2: Dimming Curve setting
(“<1>” shows logarithmic dimming,
“<2>” shows linear dimming). - Parameter 3: Dimming smoothness setting
(“<1>” shows smooth dimming,
“<2>” shows standard dimming). - Parameter 4: Digital display showing setting
(“<1>” shows always ON,
“<2>” shows OFF). - To exit the system mode, long press the “M” button for 1
second. The system will also self-exit after 8 seconds of no
operation.
4. Restore Factory Default:
To restore the decoder to factory default settings, follow these
steps:
- Under unlock status, long press the “M” button for 10 seconds
until the digital display shows
“<RST>“.
