Wiring Diagram:

1 Connecting LED lights:

2. DMX console onnectionc :

An amplifier is needed when more than 32 decoders are connected, signal

amplification should not be more than 5 times continuously.

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.

LT-905-OLED is equipped with 2 types DMX

terminals for users’ selection. The following

diagram takes 5-pin XLR as an example,

same connecting method for RJ45.

These 2 terminals can be connected in a mixed way.
