Ⅳ. Decoder address setting

This decoder occupies 3 addresses, adopted Dip switch to set the

address, the Dip switches from 1 to 9 are a kind of binary value

coding switches used to set DMX512 initial address code, the

correlative bits is the 1-9 bits of the DIP switch, the 1st bit is LSC,

the 9th bit MSC , 512 addresses totally.

DMX512 initial address code is equal to the total amount of the Dip

switches’ number from 1 to 9, press Dip switch downward (ON: at

position “1”), user can get the number of its position, if pressing

upward (at position “0”), the number of its position is 0.

LT-8030 DMX512 Decoder Manual Page 5 of 16

Example 1: Set to 37

Set the 6th, 3rd, 1st bit of the DIP switch downward to “1”, others

to “0”(picture 1), the total sum from 1 to 9 is 32+4+1, so the

DMX512 initial address code is 37.

Accept DMX512 signal only when the DIP switch FUN＝OFF

(at position “0”)

Picture 1

Example 2:

Set DMX512 original address code as 328: Set the 9th, 7th, 4tht bit of

the DIP switch downward to “1”, the rest to “0”(as picture 2),

the total sum from 1 to 9 is 256+64+8, so the DMX512 original

address code is 328.

Ⅴ.Instructions for other functions

1. Testing function：

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

Picture 3:

SWITCH1－9 OFF：BLACK

SWITCH1 IS ON：RED

SWITCH2 IS ON: GREEN

SWITCH3 IS ON: BLUE

SWITCH4 IS ON: YELLOW

SWITCH5 IS ON: PURPLE

SWITCH6 IS ON: CYAN

SWITCH7 IS ON: WHITE

SWITCH8 IS ON: 7 CLOLOR JUMPING (8 SPEED LEVELS)

SWITCH9 IS ON: 7 COLOR SMOOTH (8 SPEED LEVELS)

Picture 3

2. Color jumping & color smooth

When decoder is at testing mode, DIP Switch 8 is at “ON”, it’s

the 7 Color Jumping, when DIP Switch 9 is at “ON”, it’s the 7

Color Smooth, with 8 speed levels for each effect.

SWITCH 1－7 OFF：SPEED 0

LT-8030 DMX512 Decoder Manual Page 7 of 16

SWITCH 1＝ON：SPEED 1

SWITCH 2＝ON：SPEED 2

SEITCH 3＝ON：SPEED 3

SWITCH 4＝ON：SPEED 4

SWITCH 5＝ON：SPEED 5

SWITCH 6＝ON：SPEED 6

SEITICH7＝ON：SPEED 7

Picture 4

As Picture 4. When several DIP SWITCH at “ON” at the same time,

comply with the largest value switch, the testing function is when

FUN＝ON, DIP SWITCH 8 & 9 for the color changing function, DIP

SWITCH1－7 for the speed function, comply with the largest value

switch , SPEED 7 is the fastest speed.

3. Manual control mode:

In this mode, the dip- switch 10 is flipped to the “OFF” position. Flip the dip-switch

1-3 to set the intensity of Red LEDs, dip-switch 4-6 to set the intensity of Green

LEDs and dip-switch 7-9 to set the intensity of Blue LEDs. Please refer to the

following table for further information.

4. Note：Two versions for LT-8030 decoder, one has 3 dmx addresses, the other

has 4 dmx addresses.

3 DMX ADD Version:

The 1st address controls LEDs on CH1,0-255 steps of brightness.

The 2nd address controls LEDs on CH2,0-255 steps of brightness.

The 3rd address controls LEDs on CH3,0-255 steps of brightness.
