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
4.2 Self-testing Mode:
DMX address value = the total value of (1-9), to get the place value when in “ON” position,
otherwise will be 0.
e.g., the defaulted initial address is 1, please find
their corresponding relationships in the form.

LT-840-350 is equipped with 3 types DMX terminals for users’ selection. The
diagram takes 3-pin XLR terminal as an example, same connecting method
for the rest two: green terminal(with amplifier function) & RJ45 terminal.
LT-840 350 DMX/RDM 4CH CC Decoder-
5.1 Decoder can be connected to a variety of standard DMX512 devices:
Series 1~12pcs 1W LEDs×4CHSeries 1~12pcs 1W LEDs×4CHSeries 1~12pcs 1W LEDs×4CH
LT-840-350 works on the technique of voltage reduction the voltage of power
supply should be no less than the total voltage of the connected lamps.
,
The LED quantity at each channel can be different; LT-840-350 could auto check
and output a proper voltage to each channel according to its LED quantities.
*
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 decoder 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
