Dip Switch Operation:
4.
RDM Mode: The dip switch 1-10 are OFF.
FUN=ON (the 10th dip switch=ON)
Self-testing Mode:
FUN=OFF (the 10th dip switch=OFF)
DMX Mode:
Setting DMX addresses with dip switch 1-9
FUN=OFF (the 10th dip switch ) Mode=OFF DMX
4.1 How to set DMX address via dip switch:
E.g.1: Set Initial Address To 32. E.g.2: Set Initial Address To 37. E.g.3: Set Initial Address To 178.
001+004+032=37 002+016+032+128=178

DMX Console
LT-8048 is equipped with 2 types DMX terminals for users’ selection. The
diagram takes XLR-3 terminal as a example, same connecting method for the
green terminal (with amplifier function) .
Terminal resistor
5.1 Decoder can be connected to a variety of standard DMX512 devices:
*
An amplifier is needed when more than 32 decoders are connected, signal amplification should not be more than
5 times continuously.
*
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 connect 0.25W 90-120Ω

when too many DMX decoders are connected or signal line is too long, signal
amplification should be no more than 5 times continuously.
AMP interface can be used for signal amplification
These 2 terminals can be connected in a mixed way.
