LT-905-OLED is equipped with 2 kinds of DMX
terminals for users’ selection. The following
diagram takes 5-pin XLR as an example,
same connecting method for RJ45.

An amplifier is needed if more than 32 decoders are connected
, signal amplification should not be more than 5 times continuously.
or use overlong signal

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.

*Installation attentions: 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

Installation distance > 20mm
These 2 terminals can be connected in a mixed way.
