Wiring Diagram:
LT-924-OLED is equipped with 4 types 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).
1. DMX console onnectionc :
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.

RJ45 Connected in Parallel
These 4 terminals can be connected in a mixed way.

Installation Attention : please reserve enough ventilation distance between decoders (>20mm),
be sure not to block the vent, or will affect lifetime of decoder for .poor heat dissipation
