Accessories

Switching power supply

1. The selection according to the voltage standards and total power of the load, and the power voltage standards must be the same as the load voltage standards, and the load total power should be less than or equal to 80% of the switching power supply rated power.
2. When the constant voltage controller is used in places with noise requirements, it is recommended to use the glue-filling switching power supply, because it’s PWM dimming, current transients make the switching power supply emit noise, and the volume of noise depends on the manufacturing process of the transformer, and the gluing power supply can effectively limit the generation of noise due to the sealing of the transformer gap with glue.

Power wire

1. The selection of wire should be based on the load current and refer to the electrician’s manual, ensure that the working current is within the safe load capacity of the wire, otherwise, there is a risk of overheating and burning or accelerated aging.

DMX512 signal wire

1. The signal wire must use the internationally recognized shielded twisted pair wire or super category 5 network wire, whose diameter is 0.3mm² or more, when using category 5 cable, D+ and D- signal wire must be on the same twisted pair to reduce common mode interference.
2. DMX wiring should be separated from other strong and weak power, separate casing wiring, so as not to be interfered with by other signals.

DMX512 System Wiring

1. DMX512 system allows connecting to up to 32 decoders, the length of the signal wire <150 m, when exceeded 32, a signal amplifier should be added behind the 32nd decoder or 150 meters of the signal wire.
   • Example of long-distance DMX signal transmission:
2. The end of the DMX signal wire (i.e., the D+ and D- terminals of the last decoder on each DMX link) should be connected in parallel with a 120Ω terminating resistor to match the impedance to prevent signal reflection.
3. DMX512 signal wire adopts a “hand in hand” type bus structure, forbidding the use of a “star” connection and a “T” connection.
4. Connect the ground signal wire of all DMX512 decoders with a shielded wire.
   • If necessary, connect a 2-10uF capacitor to the ground to filter out high-frequency interference.
5. The cable layout should be straight and free from twisting, looping, forceful pressure, or damage.
   • Signal cables, power cables, twisted pair cables, Fiber optic cables, and other weak power cables in the building should be wired separately.
   • When wiring in strong interference environments, it is required to cover shielded twisted pair cables with galvanized steel tubes.
   • Wiring should be straight, and should not be twisted or looped.
   • Cables should not be subjected to physical force or damage.
   • Weak cables should be wired separately.
   • Cover shielded twisted pair cables with galvanized steel tubes when wiring in strong interference environments.
6. The DMX master, decoder power supply, and the box of the decoder power supply must be grounded, and make sure the grounding is good.
7. Wiring should be put away from high-voltage cables, and should not be parallel or bundled with power cable (separate strong and weak wiring). refer to the figure at right.
8. In a DMX512 system, must use the same cable and reduce the number of points of contact in the line as much as possible.
   • Make sure the joints are well-soldered and tightly wrapped to avoid looseness and oxidation.
9. Testing whether single lights are responding to the DMX signal as expected first.

4-Channel Constant Voltage

4-Channel Constant Voltage LED Decoder (D4-P) DMX address and parameter settings

• Channels number , PWM frequency, dimming curve, and other system parameter settings
• Long press the M a nd ◀ keys at the same time for 2s, and prepare for setup system parameters: decode mode, grey level, output PWM frequency, output brightness curve, default output level, and automatic blank screen.
• Short press the M key to switch six items.
• Decode mode: short press ◀ or ▶ key to switch 1/2/4 channel decode mode (“d-1”, “d-2” or “d-4” ). When set as 1 channel decode, the decoder occupies only 1 DMX address, and four channels output the same brightness of this DMX address.
• Grey level: short press ◀ or ▶ key to switch 8bit ( “b08” ) or 16-bit ( “b16” ). Choose 16 bits if the DMX master supports 16 bits.
• Output PWM frequency: short press ◀ or ▶ key to switch 250Hz (“F02″), 500Hz (“F05″), 1000Hz (“F10″), 2000Hz (“F20″), 4000Hz (“F40″), 8000Hz (“F80″) or 16000Hz (“F16″).
• Higher PWM frequency will cause lower output current, and higher power noise, but more suitable for the camera (no ickers for video).
• Output brightness curve: short press ◀ or ▶ key to switch linear curve(“C-L”) or logarithmic curve(“C-E”).
• Default output level: press ◀ or ▶ key to change the default 0-100% level (“d00″ to “dFF” ) when no DMX input signal.
• Automatic blank screen: short press ◀ or ▶ key to switch enable (“bon”) or disable(“boF”) automatic blank screen.
• Long press the M key for 2s or timeout 10s, and quit system parameter settings.

DMX Decoder Mode

• Short press the M key, when displaying 001~512, enter DMX mode.
• Press the ◀ or ▶ key to change the DMX decode start address(001~512), long press for fast adjustment.
• If there is a DMX signal input, will enter DMX mode automatically.
• DMX Dimming: Each D4-P DMX decoder occupies 4 DMX addresses when connecting the DMX console.
• For example, the defaulted start address is 1, and their corresponding relationship is in the form.

Self-test mode

• Enter self-test mode only when the DMX signal is disconnected or lost.
• Short press the M key, when displaying L-1~L-5, and enter self-test mode.
• Press the ◀ or ▶ key to change the mode number(L-1L-5).
• The self-test mode includes four channels that light up separately or synchronously.

DMX address setting

• When each decoder is set to the same DMX start address, multiple decoder lights can be controlled at the same time.
• When each decoder is set to a different DMX start address, multiple decoder lights can be controlled independently.
• For example, each decoder uses four addresses, and the decoder address order is set to 1, 5, 9, 13….. .509, then it can independently control 128 RGBW lights, and achieve various colorful and dynamic lighting functions.

Installation Application Example

The DMX512 system can be used in the ballroom for wide-area, multi-zone group control via wireless or wired connection.

• Don’t stack products, and place them at a distance of≥20cm, to avoid poor heat dissipation affecting lifespan.
• Don’t stack products and switching power supplies, and place products and switching power supplies at a distance of ≥20cm, to avoid interference from power supply radiation.
