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)→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.

3.2 Debugging Procedure
Step 1: Click “MENU” to enter into main menu interface and click “Device Mode” to select
splicing mode: copy mode, horizontal mosaic, and vertical mosaic.
Note: Copy Mode: all output contents are consistent; horizontal mosaic: contents of all
outputs are arranged horizontally; vertical mosaic: contents of all outputs are arranged vertically;
Step 2: select suitable splicing mode and click “OK”; get back to main menu interface to
select “Screen parameter” and enter into its setting interface. Set loaded screen point of each
output interface and click “Confirm” after inputting, and then screen splice is finished.
Note: there are two ways for number input:
(1) Adjust by rotate knob. Step length can be adjusted by “×1”“×10”“×100”, for
instance, “×100”means that number of rotate knob increases by 100 each time.
Input by number of the front panel. For example, of the key refers to figure 1.
Step 3: get back to main menu interface to select “Image layout” and enter into image
number selecting interface to select image number required to be set.

Note: This step should be skipped if full display of signal source is required on large screen;
while if certain signal source of multi-image is needed to be extracted, only setting of signal
source image is required; if horizontal size or vertical size is 0, it means no local extraction is
required in this direction.
Step 6: Click “MENU” and return to main menu interface; select “Save setting” to enter into
Data storage interface; select any mode and click “OK” to save data.
Note: Mode 1 is default startup data of device boot; it’s suggested that the most common
mode or that required by device boot should be saved to Mode 1.
At this point, basic device debugging is completed. If there is other requirement, repeat the
operation and save it as other mode.
After device debugging, just call saved data according to different condition requirements in
later stage.
Data call is divided into forms:
(1) For Shortcut key call, only click of “M1-M6” in front panel is required, which is
convenient when mode scenario is few.
(2) For User mode call of Main Menu, click “MENU” and select “User Mode” to enter into
its extraction interface. Then select desired mode and click “OK”.

size of each output interface.
Note: Input according to corresponding transmitting card size of each output interface. For
OUT1, its horizontal size is 960 and vertical size 896; for OUT2, they are 1216 and 896 respectively.
Step 3: After inputting, select “Confirm” and return to main menu interface. The large screen
splicing is finished, select signal source needed to display on screen and click corresponding key.
E.g.: for display of computer signal on large screen and connection of computer DVI interface
with “S1-DVI” port of the back device, just click “S1” in the front which means choosing the
signal to display on the screen.
Step 4: After selecting signal and normal display of large screen, save all setting data. Click
“MENU” to enter into main menu interface, and then get into “Save setting” interface to select
“Mode 1” and click “OK”. Things will be fine when it suggests saving successfully.
Note: Mode 1 is default startup data of device boot; it’s suggested that the most common
mode should be saved to Mode 1 and the device can save 32 kinds of modes at most.

For above operation which has fulfilled the first requirement of the program, namely splicing
of the whole screen, image is displayed completely and correct data are saved. For the second
requirement which is that screen is divided into three parts with proportion of 1:2:1, only further
setting on operation above is needed.
Step 5: Click “MENU” and enter into main menu interface and select “Image layout” then
Layout 3.
Note: Default layout of the device is three equal parts. If it is desired, there is no need to carry
out step 6. If not, the following operations are required.
Step 6: Click “OK” to return to main menu interface and select “Image parameter” to enter
into its setting interface. Set the following parameters:

Note: The full screen size is 1792x1344 and image proportion is required as 1:2:1, so the sizes
of the three images are respectively 448, 896 and 448. As the left images starts from the far left,
its horizontal position is 0. The middle image follows the left image, so its horizontal position is
448. The right image follows the middle, so its horizontal position is 448+896=1344. The vertical
direction always starts from the top, so the vertical position is 0. In summary, both horizontal and
vertical positions of image 1 are 0 and horizontal and vertical sizes are 448 and 1344 respectively;
Horizontal and vertical positions of image 2 are respectively 448 and 0 and horizontal and vertical
sizes are 896 and 1344 respectively. Horizontal and vertical positions of image 3 are respectively
1344 and 0 and horizontal and vertical sizes are 448 and 1344 respectively.
Step 7: According to operation above, screen body has been divided into three images with
proportion of 1:2:1. Default display content of each image is S1. If different signal sources should
be designated for each image, click of front panel to enter into image switch interface. Select
image by rotate knob and choose signal by click of S1-S6 of front panel. E.g.: if signal of image 2
is S6, click “WIN” to enter into image switch, then adjust rotate knob to image 2 (it’s selected if
padded) and finally click “S6” of front panel. After selecting each image, save final data which is
the same with step 4.
Up to now, program debugging is finished. If any display method is needed in later stage, it’s
just OK to call saved mode. There are two ways for mode call. When mode number is not big, just
click M1-M6 of front panel which are shortcut key for mode call; when mode number is big (over
6), user mode call should be made. Click “MENU” to enter into main menu interface, then select
