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

5. Wiring Diagram:
LT-830 8A DMX/RDM 3CH CV Decoder-
5.1 Decoder can be connected to a variety of standard DMX512 devices:
*
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 terminal resistor
*
An amplifier is needed when more than 32 decoders are connected, signal amplification should not be more than 5 times
continuously.
