II. Sending card setup
The setup for the sending card is very simple; if your display is work normally under the
1024*768 mode, nothing changes; otherwise choose the right mode according your display, then
click “Save on sender”. (Remarks: the display mode refers to PC display mode.)
III. Receiving card setup
Users can choose one panel alone for testing, or choose one of panel of a whole display
connected well for testing.
Before entering the setup dialog box, having a knowledge of all items on the operating
interface is very important.
Present scan mode: after finishing intelligent setup, software interface will write out drive
mode for present panel.
File: after finishing intelligent setup properly, users save drive setup, and name the drive file.
For example: full-color 1/8 scan 8 rows/zone.
Led display refresh frequency: The refresh frequency is higher, image on the screen will
more stable, and much clearer. If you want to use camera to shoot image on the display without
ripple and flicker, you should setup the refresh frequency above 600HZ. Generally speaking,
towards double-color screen, if you don’t pay attention to image effect on your display, setup
refresh frequency as 60—75HZ; towards indoor display, you can setup 180—600HZ; towards
outdoor display, setup 300-1200HZ.
Synchronous frequency: Selecting this item can make computer and led display
synchronous, thereby display effect will more perfect.
Gray level: In general, gray level 256 is Ok for double-color display; gray level 4096 for
indoor display; gray level 16384 for outdoor display. Of course, you can choose higher gray level
for your display according to your requirement. The higher the gray level, the better the image.
Scan clock: It is up to design and performance of drive board. If drive board has a reasonable

E-mail: leddisplays@hotmail.com
design and good performance, it can reach high scan clock, so single receiving card can support
more pixels.
Duty ratio: it refers to scan clock duty ratio, changing this data can make the scan clock
reach higher data. Generally, setup the duty ratio as 50%.
Blanking time: It is used to clear dim brightness. Setup 3000 for double-color display;
setup 200 for full color display. (real pixel and virtual pixel).
Gray equalize: The default value is 1; generally, most Led screens don’t need to adjust this
item. The normal gray displays from darkness to brightness, as shown in below figure:
Some panels are not of good quality, so the gray doesn’t display regularly; if users adjust this item,
it is possible to make the gray normal. The adjust value range: 0-15.
Virtual display: if your display is virtual display, and it is under virtual mode, you should
select this item.
Max width: One receiving card can support the max width pixels. It is close to refresh
frequency, gray level and scan clock, and it will change with the three items.
Actual width: It refers to actual width of display.
Max height: One receiving card can support the max height pixels. It is close to drive board
Actual height: It refers to actual height of display.
Intelligent setup: There are 7 steps for it. (Some drive board will skip some steps when
you testing it.) It is used to test drive mode and signal trend of drive board. After finishing the
intelligent setup properly, your panel can work normally.
Load from files: If you tested this kind of panel before, and saved the drive setup, you can
load corresponding file from computer directly, don’t need to reset.
Save on files: After testing panel, our control system will detect the drive mode and signal
trend of the panel, and then create a program file. You can name the file, and then save it in
computer. Next time, you test the same kind of panel; you can load the program file from
computer directly, and don’t need to do “intelligent setup” again.
Send to receiver: After finishing the intelligent setup, you will change other items in the
receiving card setup interface according to display requirement. Remember to click “Send to
receiver” when you change data for one item or multiple items, otherwise, the setup won’t put into
effect. When you load from file to call program for testing same kind of panel, remember to click
“Send to receiver”, otherwise, the setup is not efficient, and receiving card can’t work.
Save on receiver: Click this item can save the receiving card setup into the receiving card
Pixel by pixel/ module by module correction: It includes four modes: single; 2*2
module; 4*4 module; 8* module. The pixel by pixel mode can support the max pixels
96*64=6144. If surpass the max pixels, please choose other modes.

Enter the receiver setup, remember not to change other items on the receiver setup interface
first, begin with “Intelligent setup”. After finishing the “Intelligent setup”, operation interface will
return to the receiver setup, users can adjust other items according to led display requirement.
The setup for receiving card is also very simple; click “intelligent setup”, input required data
following the instruction, then can recognize the scanning mode and signal trend, etc of the drive
board; adjust the refresh frequency, shift clock, gray level, etc, then click “save the file”. If the
drive board was setup before, just click “Load from file”, choose the correspondent program, then
click “send to receiver”, then the card can work normally. Click “Save on receiver” can save the
receiving card setup into the receiving card permanently.
Intelligent setups are shown below: (Make sure the correct connection for the flat connected
panel with hub card, otherwise the “Intelligent setup” can’t recognize your panel properly.
Entering the setup interface, users must do the operation and watch testing panel carefully at the
same time, because all the operation setups must follow the panel’s instructions. )

E-mail: leddisplays@hotmail.com
Watch the module, and choose the right status.
10. Compared status 1 with status2 of the module, watch which one is brighter, for example:
status 1 is brighter than status 2. Choose the right one.
11. Watch the color that the module shows, for example, status 1 displays red, and status 2
displays green. Select the right one.
Website: www.ledcontrolcard.com
E-mail: leddisplays@hotmail.com
Watch the module: one row is bright or multiple rows are bright; when multiple rows
are bright, check how many interval rows. As shown in below figure.
Notice: Interval rows mean how many black (dim) rows between two bright rows, and then
add one bright row for the total interval rows. (You must figure out all the bright rows in the panel,
but for the interval rows, you only need to figure out how many rows between two bright rows.)
For example, as shown in below figure, there is one black (mid) row between two bright rows,
choose 2 (1+1=2) rows for the interval rows, 4 rows for bright row.
If there is no black (mid) row between the bright rows, select 1 row for the interval row, as
shown in below figure: 4 rows for bright rows, and 1 for interval row.
Choose the right one according to your module.
13. Watch which pixel is bright in the module, then click the corresponding grid on the
computer screen, after clicking the grid, you will find another pixel will be bright on the module,
then you continue to click the corresponding grid on the computer screen, after click it, another
pixel will be bright on the module…. By analogy, follow the instruction on the module; the
computer will inform you when all the pixels are choice-finish.
