The LT-8020 DMX512 Data Decoder adopted the advanced decoding
technology to convert the international standard DMX512/1990 signal into
standard SPI (TTL) signal to control LED lights based on 74HC595, MB5026,
DM134, DM135, SC16722, ZQ9712, or similar chips, each decoder has 96
DMX output channels, and the output channels can be expanded by adding
decoders, therefore, most of LED lights can be controlled via the signal
convertion, such as widely used pixel light, digital tube light, spot light,
floodlight, pixel screen, dancing floor light etc.

The DMX512 initial address code is 37.
Like figure 2, Set initial address to 37, Set the “1st”,”3rd “,”6th”, bit of the DIP switch down to

4. Address Setting
Data cable
This decoder can decode 128 DMX addresses, adopted Dip switch to set the address, the
Dip switches from 1 to 9 are a kind of binary value coding switches, the 1st bit is LSC, the
9th bit MSC, can set 511 addresses totally.
DMX512 initial address code is equal to the total amount of the Dip switches’ numbers from
1 to 9, press Dip switch downward (ON: at position “1”), you can get the number of its
position, if press upward (at position “0”), the value of its position is 0.
Accept DMX512 signal only when the DIP switch FUN(10)=OFF(at position “0”)
Figure 1
Example 2: Set DMX512 original address code as 385: Set the 9th, 8th, 1st bit of the DIP switch
downward to “1”, the rest to “0” (as Figure 2), the total sum from 1 to 9 is 256+128+1, so the DMX512
original address code is 385.

5. Configuration Diagram
1. LED point source conjunction diagram
The 10th DIP switch is FUN, acting as the function key.
DMX512 Decoder works when FUN is at OFF, receiving DMX512 signals.
Decoder testing mode works when FUN is at position” ON” as Figure 3:
SWITCH1-9 OFF: BLACK
SWITCH1 IS ON: lighten 6 channels
SWITCH2 IS ON: lighten 12 channels
SWITCH3 IS ON: lighten 18 channels
SWITCH4 IS ON: lighten 24 channels
SWITCH5 IS ON: lighten 30 channels
SWITCH6 IS ON: lighten 36 channels
SWITCH7 IS ON: lighten 42 channels
SWITCH8 IS ON: lighten 48 channels
SWITCH9 IS ON: the ground color is dark, then light from the 1st channel individually to
all until lighten all channels.

NOTE: Acoording to DMX512 protocol, in order to ensure a steady data transmission, you should add a
metalster(Metal Thin Film resistor，90-120Ω 1/4 W )at the end of each layout of DMX data
cable(between Foot 2 and Foot 3, Data + and Data -), please also refer to your dmx console manual to
select a correct resistor
