3. Device Debugging
3.1 Device Connection
Device 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)→Splicing Processor
→ Sending cards → Large screen.
Control connection: connect computer with device control port and debug device
connection method. There are three connection methods
(1) Connect 100MB 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 kind of
method among the three can realize device software control.

5. Q&A
Q1: DVI, HDMI, VGA and CV Port Definition.
A: 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 often desktop and laptop.
HDMI: High Definition Multimedia Interface, a digital audio/video interface

Multi-Image Splicing Processor
10
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 and 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 often 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 usually 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: There is no password and it’s allowed to enter into with just a click.
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.
If suggestions above fail to solve your problems at last, please contact with our
customer service in time. We will assist you to solve your problems as soon as
possible.
Q6: What are the possible reasons for network overtime with network
splicing processor?
A: Possible reasons are as follows:
1. IP address of local connection is not in the same field with splicer.
2. Failure of network line or damage of the line.
3. Damage of network port of signal source.
If suggestions above fail to solve your problems at last, please contact with our
