K-4000C Addressable LED Controller
Welcome to use the SPI single channel remote transmitter/receiver.
This model is designed for the SPI signal due to the distance is not enough.
The transmitter is a TTL to differential signal output, and the receiver is a differential signal to TTL.
In this way, it can solve the problem of SPI signal distance limitation in many projects. It’s simple and small, easy to solder.
System Features
1. 32-level to 65,536-level grayscale control with software Gamma correction.
2. Supports point, line, and area light sources; supports regular patterns and irregular (custom-shape) mapping.
3. The controller has 4 output ports. Each port can drive up to 512/1024 fixtures (for DMX fixtures: max 512 pixel points, assuming 3 channels per pixel).
4. Playback content is stored on an SD card. Up to 32 effect files can be stored on the SD card. Supported SD card capacity: 128MB–32GB.
5. The controller can be used as a standalone unit or cascaded with multiple units. Cascading uses opto-isolation for better anti-interference and stability. The cascade distance between two units can reach 150 meters; use a 0.5 mm² pure copper power cable.
6. The controller’s load-IC feature can be locked to a specific IC type in software, or left unlocked and selected using the controller’s CHIP button. The latter is more flexible and convenient.
7. For DMX fixtures, the controller has a built-in addressing function. In addition, when used with LedEdit-K V3.26 or later (2016 series), it supports one-click addressing.
8. Supports 4-channel (RGBW) pixel fixtures or splitting them into single-channel pixel points.
9. Built-in effects support 3-channel RGB and 4-channel RGBW.
10. Supports third-party control via MODBUS.
11. Enhanced TTL and RS485 differential (DMX) signal outputs.
12. Includes 22 built-in test effects and a DMX512 channel test function.
Notes:
- With 512 pixels loaded, the controller can reach 30 fps; with 768 pixels, about 25 fps; with 1024 pixels, about 22 fps (values based on 1903-family ICs; performance varies by IC).
- Per the international DMX512 (1990) standard, the maximum is 512 pixel points. When driving 170 pixels (standard DMX 170 pixels), speed can reach 30 fps; at 340 pixels, about 20 fps; at 512 pixels, about 12 fps.
- For timed (holiday) playback, BeiDou wireless synchronization, or console channel assignment/distributor use cases, please contact sales or technical support for details.

Remarks:
- The maximum pixel count in parentheses is based on RGB (3 channels).
- For RGBW 4-channel fixtures, select K-8000-RGBW. For fixtures above 4 channels, select K-8000-RGBWYA.
- For single-channel fixtures, select K-8000-W (one channel equals one pixel point; effects are generated as white light in software).
