4. Kystar KS920P 4K Video Processor Connection

Kystar KS920P connection could be divided into three parts: power connection, signal connection and control connection (used for software debugging).
Power connection: device power supply. Connection method: connect power cord to power plug.
Signal connection: the method transferring signal from signal source to LED large screen. Connection method: signal source (e.g.: computer)→Mosaic Processor→Transmitting card→Large screen.
Control connection: connect computer with device control port and debug device connection method. There are three connection methods:
（1）Connect 100 mbit network control port with splicer LAN1 port, which can set device software.
（2）Connect computer gigabit network port with splicer LAN2 port, which can not only set device but also echo signal source image.
（3）Connect one crystal head of serial port line which is randomly donated by device with splicer COM port, and plug DB9 into computer serial port. Any of the three methods realizes device software control.
Connection diagram is as follows:

6. Kystar KS920P 4K Video Processor  FAQ

Q1: DVI, HDMI, VGA and CV Port Definition.

A: DVI:  DVI: Digital (HD) Video Signal, an interface standard jointly introduced by DDWG (Digital Display Working Group) combined by Silicon Image, Intel and etc. It has been optimized in speed, resolution, HDCP agreement and so on. Its signal source is normally desktop or laptop.

HDMI: High Definition Multimedia Interface, a digital audio/video interface technology. It’s specialized digital interface and can send audio and video signal at the same time with the quickest data transmission of 5Gbps. Its signal source is usually camera, laptop or information publication system.

VGA: Analog Video Signal (Video Graphics Array), a video transmission standard introduced together by IBM in 1987 with PS/2 at the same time. VGA enjoys high resolution, rapid display rate, rich color and is widely applied among color displays. Its signal source is normally desktop, laptop, VOD and Matrix.

CV: Composite video signal, also called composite video, which can pack all signals together and transfer it as a whole.  Its signal source is normally camera, DVD, Cable Box, VOD and video matrix.

Q2: Please give a brief introduction of the connection method of graphics, splicer, transmitting card, receiving card and LED.

A:  Connect graphics DVI (VGA) output port with splicer DVI-IN(VGA-IN) input—output splicer DVI-OUT to transmitting card—connect transmitting card with terminal receiving card of the back screen by network cable—connect receiving card with each screen body with control and cover whole screen by cascade.

Q3: What is output resolution?

A:  Output resolution is pixel mode output by single port of splicer and the largest control range of splicer output. Regular resolutions are: 1024*768, 1280*1024, 1600*1200 and 1920*1080, which are set with the same resolution mode of transmitting card.

Q4: What is administrator password set in PC Software?

A:  No password. Just a click is ok.

Q5: What are the reasons for failure of serial connection with the application of serial splicing processor?

A: Possible reasons are as follows:

① Wrong selection of COM port. Just click “Confirm” and re-click “opening serial port” key.

② Occupation of serial port. Two or more software windows are not allowed to be open simultaneously.

③ Failure of serial port line connection or damage of the line.

④ Damage of COM drive of the board or serial port.
