Wiring diagram
- Connecting LED lights:
- DMX console connection: D32 is equipped with 4 kinds of DMX terminals for users’ selection. The following diagram takes 3-pin XLR as an example, same connecting method for the rest three: RJ45 & 5-pin XLR & green terminal (with amplifier function).
- If the recoil effect occurs because of longer signal line or bad line quality, please try to connect 0.25W 90-120Ω terminal resistor at the end of each line.
- The connection diagram of 4 kinds of DMX/RDM terminals:
- Installation attention: please reserve enough ventilation distance between decoders (>20mm), be sure not to block the vent, or it will affect lifetime of decoder for poor heat dissipation.
- The connection diagram of AMP signal amplifier terminal:
- Connecting with green terminal or an extra amplifier will be needed when more than 32 decoders are connected or use overlong signal wire (as shown below).
- Signal amplifier should not be more than 5 times continuously.
