DIP switch
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
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.
DMX address value = the total value of (1-9), to get the place value when in “on”
position, otherwise will be 0.
001+004+032=37 002+016+032+128=178
When DIP switch 1-9 are OFF, the defaulted initial DMX address is 1.

For changing effects ( Switch 8 9=on): DIP /
DIP switch 1-7 is used to realize 7 speed
levels. (7=on, the fastest level)
[Attn] When several switches are on, subjected to the highest switch value.
As the figure above shows, the effect will be 7 color gradient at 7 speed level.

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 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 at the end of each line.
LT-903-DIP is equipped with 2 kinds of DMX
terminals for users’ selection. The following
diagram takes 3-pin XLR as an example,
same connecting method for RJ45.

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
