BC-835-DIN
DC12-24V DMX512 RGB RGBW LED Decoder
The DMX decoder utilizes an advanced computer-controlled chip to convert the globally adopted DMX-512 digital control signals into PWM controller signals for LED driving. It can be connected to a DMX digital control console and supports continuous expansion of output channels to achieve more dimming effects or various program-changing effects. When not connected to the DMX console, the device functions as a synchronization controller, enabling simultaneous control of multiple decoders and LED lights.

Wiring Diagram of DMX512 Decoder:
Direction For Use:
Decoder address settings:
Each decoder occupies 3 addresses, with address settings configured via encoding switches. The 1-9 bit encoding switches represent binary values for setting DMX512 starting address codes, where the 1st bit is the least significant bit and the 9th bit is the most significant bit, allowing a total of 511 address codes. The DMX512 super starting address code equals the sum of the bit values from encoding switches 1-9. Setting the encoding switch to the lower position (ON set to "1") activates the bit value, while setting it to the upper position (set to "0") deactivates the bit value. The DMX512 signal can only be received when the encoding switch FUN is turned off (set to "0"). The channel selection is performed by choosing the appropriate dialing position from the table below using the dialing switch.
a). instance 1：
As shown in Figure 1, set the DMX512 starting address code to 37 by setting the 6th, 3rd, and 1st positions of the encoding switch to "1" and the remaining positions to "0". The sum of the bit values from the 1st to 9th positions of the encoding switch is 32 + 4 + 1, which corresponds to the DMX512 starting address code 37. The next two channels are designated as 38 and 39.
b). instance 2：
As shown in Figure 2, to set the DMX512 starting address to 328, set the 9th, 7th, and 4th bits of the encoding switch to "1" and the remaining bits to "0". The sum of the 1-9 bits of the encoding switch is 256 + 64 + 8, which corresponds to the DMX512 starting address 328. The next two channels are designated as 329 and 330, respectively.
Other Features of DMX512 Decoder:
Test Function：
The 10th pin of the DIP switch is designated as "FUN", functioning as a function key. When FUN is set to OFF, the DMX512 decoder activates its decoding capability to receive DMX512 signals.
When FUN=ON, the decoder performs test functions as shown in Figure 3 (channel 1 connects to red light, channel 2 to green light, and channel 3 to blue light):
- 1-9 Switch OFF: Black
- Switch 1=ON: Red
- Switch 2=ON: Green
- Switch 3=ON: Blue indicates
- Switch 4=ON: Yellow
- Switch 5=ON: Purple
- Switch 6=ON: Blue
- Switch 7=ON: White
- Switch 8=ON: Colorful Flash (8-speed selection)
- Switch 9=ON: Full-color gradient (8-speed selection)
It is 7. Additionally, the signal indicator (green light) flashes slowly due to a built-in effect change in the decoder; when the DMX512 controller is enabled, the signal indicator flashes rapidly.
