2. DMX console onnectionc :
LT-912-OLED is equipped with 3 types DMX terminals for
users’ selection. The following diagram takes 5-pin XLR as
an example, same connecting method for the rest two: RJ45 &
green terminal (with amplifier function).
*
An amplifier is needed when more than 32 decoders are connected, signal amplification
should not be more than 5 times continuously.
*
connect 0.25W 90-120Ω terminal resistor at the end of each line.
If the recoil effect occurs because of longer signal line or bad line quality, please try to
