The 32CH DMX512 Constant Voltage Decoder is a sophisticated device designed for high-power multi-channel LED lighting applications, specifically for constant voltage LED lamps. It leverages advanced micro-computer control technology to convert DMX512/1990 signals into PWM signals, enabling precise control over a wide range of lighting setups including single color, color temperature, RGB, and RGBW LED lamps.

Function Description:

The primary function of this decoder is to act as an interface between a DMX512 control system and constant voltage LED lamps. It receives DMX512/1990 signals and translates them into Pulse Width Modulation (PWM) signals, which are then used to control the brightness and color of connected LED lamps. With 32 output channels, it can manage a large number of individual LED segments or lamps, offering flexibility for complex lighting designs. The device supports both 8-bit (256 levels) and 16-bit (65536 levels) grey level options, allowing for very smooth and detailed dimming and color transitions. It also incorporates RDM (Remote Device Management) protocol, which enables remote configuration and monitoring of the decoder from an RDM master console. This includes browsing and setting parameters, DMX address configuration, and equipment recognition, streamlining the setup and maintenance process for large installations. The decoder also features a power-off data saved function, ensuring that settings are retained even after power interruptions.

Important Technical Specifications:

• Model: 32CH DMX512 Decoder
• Input Voltage: DC5V-24V
• Max Load Current: 3A per channel, with a maximum total of 96A across all 32 channels.
• Max Output Power:
  • 480W at 5V
  • 1152W at 12V
  • 2304W at 24V
• Output Scale Level:
  • 256 levels (8-bit)
  • 65536 levels (16-bit)
• Input Signal: DMX512/RDM
• Output DMX Channel: Constant Voltage PWM × 32CH
• Output Frequency: Selectable options of 1K, 2K, 4K, 8K. The recommended frequency is 1K.
• Decode Channel: 32CH
• DMX512 Socket: XLR-3R, RJ45, and Terminal block. The green terminal ports also feature a signal amplifier function.
• Control Mode: DIM/CT/RGB/RGBW, selectable via a 4-mode switch.
• Dimension: L195 x W145 x H38 (mm)
• Weight (G.W): 810g

Usage Features:

The decoder is designed for ease of use, featuring an OLED screen and touch buttons for intuitive operation.

• OLED Screen Interface: The OLED screen displays current settings and parameters. Navigation is done using "M" (mode), "+" (increase), and "-" (decrease) buttons. A long press of the "M" key unlocks the screen after a 10-second inactivity period, which also serves as a lock screen interface displaying key parameters. A star symbol flashes on the screen when a DMX signal is detected.
• DMX Address Setting: Users can set the DMX address from 001 to 512 using the "+" and "-" keys on the main page.
• PWM Frequency Selection: The output PWM frequency can be selected from 1K, 2K, 4K, or 8K, with 1K being the recommended setting for most applications.
• Grey Scale Options: The decoder supports both 8-bit and 16-bit grey scale levels. The 16-bit option is available if the master controller supports this function, providing finer control over dimming.
• Dimming Curve: Users can select from standard, linear, LOG, or custom dimming curves ranging from 0.1 to 9.9. A value of 1.8 is recommended, while other values are for special requirements. This setting is only available for 8-bit operation.
• Control Modes: The device supports four control modes: DIM (dimming), CT (color temperature), RGB (red, green, blue), and RGBW (red, green, blue, white), allowing it to adapt to various LED lamp types.
• Built-in Test Mode: The decoder includes a built-in test mode with 11 different pre-programmed sequences (M0-M10) for testing and troubleshooting. In test mode, all 8 outputs are controlled synchronously. These modes include:
  • M0: RGBW can be dimmed separately in static mode (brightness adjustable).
  • M1: 3 color skipping (brightness, speed adjustable).
  • M2: 7 color skipping (brightness, speed adjustable).
  • M3: White color strobe (brightness, speed adjustable).
  • M4: 3 color smooth (brightness, speed adjustable).
  • M5: Full color smooth (brightness, speed adjustable).
  • M6: RG color smooth (brightness, speed adjustable).
  • M7: RB color smooth (brightness, speed adjustable).
  • M8: GB color smooth (brightness, speed adjustable).
  • M9: White color fade & change (brightness, speed adjustable).
  • M10: Great cycle (all mode cycle).
• Connectivity: The decoder offers versatile connectivity options for DMX signals, including 3-pin XLR, RJ45, and green terminal blocks. The green terminals also provide a signal amplifier function, which can be useful for longer signal lines. For RDM control, only 3-pin XLR terminals are normally used.
• Power-off Data Saved: All settings and configurations are saved automatically, preventing loss of data during power interruptions.

Maintenance Features:

The product comes with an after-sales policy that includes free repair or replacement services for quality problems within 3 years of purchase, provided the product has been used correctly according to the instructions. However, certain conditions void this warranty:

• Defects caused by wrong operations.
• Damages resulting from inappropriate power supply or abnormal voltage.
• Damages due to unauthorized removal, maintenance, circuit modification, incorrect connections, or chip replacement.
• Damages incurred during transportation, breakage, or water submersion after purchase.
• Damages caused by force majeure events such as earthquakes, fires, floods, or lightning strikes.
• Damages due to negligence, improper storage in high temperature/humidity environments, or exposure to harmful chemicals.
• The product has been updated (implying that the warranty applies to the original version).

Safety Warnings:

• Avoid installing the controller in areas with lightning, intense magnetic fields, or high voltage.
• Ensure correct connections to prevent short circuits, component damage, and fire.
• Mount the unit in an area with proper ventilation to maintain an appropriate operating temperature.
• Verify that the voltage and power adapter are compatible with the controller (DC12-24V constant voltage power supply).
• Do not connect cables with power on; always check for correct connections and no short circuits with an instrument before powering up.
• Do not open the controller cover or attempt to operate it if problems occur.
• If signal lines are long or of poor quality, causing signal recoil effects, connect a 0.25W 90-120Ω terminating resistor at the end of each signal line to resolve the issue.

Power Source Selection:

It is crucial to use a DC constant voltage type of power supply. Due to the fact that some power supplies only provide 80% of their total efficient output, it is recommended to select a power supply with at least 20% higher output power than the total consumption of the LED lights to ensure stable and reliable operation.
