Composition of Splicing screen
The company splicing products embedded splicing function, divided into
splicing machine and splicing box + screen body two, the control mode is
through RS232 serial port ring splicing unit connected to the computer using
control software control, the difference is that the machine uses a double
male RS232 line in and out of the series, RS232 input port connected to the
computer end, The splicing box uses a standard straight line in and out serial
connection, and the input port uses an RJ45 to RS232 connector to connect the
serial line to the computer control end.
A complete Mosaic consists of the following parts:
Splicing unit: responsible for the incoming signal is processed internally and
displayed on the screen.
Distributor (matrix, processor): responsible for sending the video signal into
each splicing unit, the difference is the distributor to copy a signal for
multiple signals, the matrix for each way to copy the input signal for
multiple signals according to the need to send to different screens, the
processor will be different types of signals converted to HDMI signals in
order to put on the screen. Signal cables: the signal cables that are required
for splicing projects of HDMI, DVI and VGA signals, and their quantity and
length depend on engineering requirements.
Control cables: Standard RS232 serial port cables are used for connection
between splicing units, standard RJ45 direct connecting network cables are
used for connection between splicing boxes and a RS232 to RJ45 adapter is
added finally, and RS232 serial port cables or a piece of USB to serial port
cable can be used on the computer control side. See Fig.1.1.3 for example of
USB to serial port cable. Brackets and exteriors: Aiming at supporting the
whole splicing wall, they are classified into vertical type and front-
maintenance type. Featured with convenient and stable installation, the
vertical type is erected and fixed on the ground with gaskets and expansion
bolts by drilling holes on the ground. And the front-maintenance type is fixed
on wall by drilling holes, which facilitates maintenance in later phases, but
its installation and adjustment is complicated.
Wiring of Splicing screen
1. Wiring of control cables for Splicing screen
The connecting cables for splicing screen of this company include signal
cables and control cables. The entire large screen is serially connected by
the control cables in the mode of one-in one-out looping, and there are mode
of RS232 serial port cable looping and mode of RJ45 network cable looping, the
detailed wiring principle is shown as Fig. 2.1.1. The first level of the
splicing unot can be selected freely.lt is not necessarily 1#.The number of
splicing units should be set in OSD menu manually.Please refer to the
following three principles:
- The number begins with 1.
- The number increases from left to right.
- The number increases from top to bottom.
The connection principle of splicing units follows:
- Each splicing unit must be connected.
- Signal cable used must be as short as possible.
For additional matrix devices,a serial cable is needed to connect the
RS232 output port of the splicing unit and RS232 port of matrix.
With regard to extra matrix device, a serial port cable is required for
connecting the RS232 output port at the terminal of the splicing units and the
RS232 port of the matrix.
2. Wiring of signal cables for Splicing screen
The signal types that are supported for splicing are HDMI and DVI, VGA and
supports splicing display of various types of signals as above.
How to Operate Splicing screen Software
1. Interface of control software
Note: A part of menus and options may be slightly different due to
software update, but the operation is basically the same. 2. Communication
settings The [COM (Serial)] and [LAN (Network)] in [Communication Settings]
correspond to the serial setting and network setting respectively.
When the [serial] communication is enabled, as shown in Figure 3.2.1 above,
select the serial port number connected in accordance with the serial
connection configuration (you can correspondingly view the COM port occupied
by the RS232 line connected to the computer console (Figure 3.2.2), the baud
rate needs to be set to 9600, the data bits, parity bits, stop bits are set
according to the actual situation, usually save the default state, finish by
clicking [OK]. When [Network] communication is enabled, as shown in Fig. 3.2.3
above, the network connection requires the corresponding connected device to
support connection via LAN, and the search of the device is performed under
the open network connection. Select the corresponding [search mode] – default
search to broadcast the current LAN. The received device returns the IP
information of the device to prove that the device can be connected. For
Specific search, the device is detected based on an IP network segment and the
port of the device. The device exists if it can be connected. The above two
ways to LAN communication connection search; to ensure that there are results
for the search of the device to be selected (said to connect), to complete the
connection configuration click [OK].
3. Splicing setting
In Splicing Settings, you can control the splicing rows and columns and
configure the corresponding splicing scheme. As shown in fig. 3.3. When
selecting the corresponding rows and columns of splicing, the rows and columns
determine the number of splicing operations (example: 22). There are
compatibility Settings for different motherboards in [Mainboard Type]. Select
the corresponding model (it can be refreshed automatically when unknown) and
load the corresponding board type information. The software can be compatible
with the normal use of various motherboards.
4. Remote control
[Remote control] It is equivalent to virtual remote control interface, as
shown in Fig. 3.4. You can enter the menu, using the virtual button menu,
source selection switch and exit. 5. Picture color temperature

display of each unit after splicing, as shown in Fig. 3.14. 15. Serial
number settings
[Serial number settings] The serial number of the splicing unit can be
modified. To set the serial number, the device need to be connected
separately. In the case of series connection, all the serial numbers of the
device will be overwritten. Authority code (123654) as shown in Fig.3.15.
16. Matrix
[Matrix] For linkage control of splicing external matrix devices, you need to
set the protocol model of the corresponding matrix (different vendors have
different matrix protocols), the address of the matrix (the device address is
usually 0), and the number of channels (output channels are set according to
the number of splicing). The matrix number corresponds to different matrix
protocols, and the linkage control can be controlled only when the matrix
corresponding to the protocol is selected. See Fig. 3.16. When [Matrix] is
done, enable matrix linkage setting, right – click menu on the page to switch
matrix source settings. Shown as Fig. below:
Troubleshooting
1. Prompt serial port opening error
If an error occurs as shown in Fig. 4.1.1 when software is opened, check the
connection of the entire RS232 control line to ensure normal connection and
communication, and check the COM port Settings of the local computer to ensure
correct configuration, as shown in Fig. 4.1.2 (taking the common USB-to-serial
cable as an example, COM19 is the COM port occupied by the USB-to-serial
tool). 2. Abnormal image display
When the screen is awoke and abnormal display is found, such as color spots,
flashing lines, jitter, etc., first check whether there is any damage on the
appearance of the screen, then cross detect signal lines and signal ports of
external devices, and finally try to enter factory mode to reset.
There are two ways to enter factory mode:
1). Press Menu+8202 for the remote control, select the screen for control
software.
