LPD6803 Dmx led decoder(Support LPD1101,D705,UCS6909,6912)

Descriptions:
LED  DMX512 Decoder of LPD6803(LPD6803 is a 3 channel constant-current driver and grey-level modulate
output, it uses advanced high-voltage CMOS technology,provide 3-way,designed to meet the needs of driving
function in the led lighting system,especially in the dissociation with mutual grey level in the full-colour lighting
system..)  is to convert the DMX512 digital signal into SPI(TTL)  digital signal and it  compatible with
LPD6803.ThE DMX Decoder of LPD6803  console can control every channel of the LED Lights with
PWM signal.The grey scales of DMX decoder depends on the driving IC,  the above driving ICs are
with a built-in grey scale processor and occupy 70-80% of LED digital lighting market, use our DMX
-SPI decoder can simply turn normal LED digital light to DMX512 LED light with international standa
-rd  communication protocol, which is easy to promote in the international market.

How to set DMX address via dip switch:

When FUN=OFF, Decoder is DMX controlling mode, When FUN=ON, Decoder is self-test mode
1. Set DMX512 original address


When FUN=OFF,Decoder is DMX controlling mode
When FUN=ON,Decode if self-test mode

2.Testing mode:

Note: When use DMX512 protocol,you Need a resistor with 90~120Ω 1/4 W between 2 and 3 base (signal
positive and signal negative)  of each channel DMX signal  cable’s most end according to DMX512 protocol
specification for the high-speed and more stable data transmission system.Categories.Signal DMX Decoder
merely output the signal to the LED lights which can be controlled in spite of the working voltage.
