2. DMX console onnectionc :

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.
