CR-4000

CR-4000 LED Screen Controller

1. LED screen controller can receive video signals and distribute them to each output port. Use embedded DSP and embedded 32bit processor to achieve spatial switching of the screen, to make a better reducibility of color. Meantime use virtual resolution, uniform illumination, gamma correction etc. and to make the screen more verisimilar and colorful.

2. LED screen controller can support video data maximum to 1920X1080P. It suports DVI, SD-SDI, and HD-SDI High-definition video signal input.

3. LED screen controller has two models: CR-4000 and CR-4500, CR-4500 has cascade function and CR-4000 can be used as terminal cascade.


Features

1. Performance is stable and reliable.


2. Supporting SD-SDI, HD-SDI, 3G-SDI format for high-definition video signals.


3. The input video data is processed and distributed to every port; the maximum high-definition video data format can up to 1920x1080P.


4. Real-time monitoring of LED screen body controller and the temperature of LED cabinet.


5. Receiving all the screen body parameters sent back from every port and then transmitting to the control software.


6. Video processing uses virtual pixel technology and it supports brightness uniformity correction, gamma correction technique, parameter adjustment, data format processing. 7. Both the LED screen box body controller and the LED fan support for manual and automatic control.


8. Using embedded DSP technology and embedded 32bit processor, achieving adaptive conversion of color space.


9. Using high-precision eight-layer PCB board design, can effectively reduce the electromagnetic interference.


10. Supporting RJ45/RS232/RS485 control.


11. With 8-channel gigabit network port (CR-LNA) to send video data, assuring highly efficient and stable signal transmission.


12. The indicators in the front panel show the working status.


13. Supports consistency of LED lights and has the ability of the parameter saving.


14. Two output ports can simultaneously connect a network from beginning to end to form a ring connection and have the hot backup, ensuring the stability of the system. It can also be mounted separately in different networks.


15. Support equipment cascade.


16. Through the configuration settings of the software, it can set all the parameters of this device.


17. The environment detector parameters can monitor all the parameters in real time.


18. Supporting over-current, over-voltage protection and code protection.


19. Supporting the big-screen outage, protecting circuits and software, ensuring that the screen will not be a static and constant lighting body and protect the screen body from overheat.


20. the case are fixed in two ways: Cabinet fixing and hanging fixing.


21. 8kv electrostatic protection.
