I. Product descriptions
With the rapid development of the LED display industry and the growing demands for applications, all control
requirements arise at the right moment for controlling of the large-screen control system. However, due to the
limitations to the large-screen control system in image processing, frame control and signal format conversion, the
LED large-screen control system is somewhat weak and can not meet users’ needs mainly because:
1. The signal source access format is limited for LED large-screen control systems and currently only the digital
DVI signal can be used, but many signal sources (for example, VGA, etc.) can't be directly displayed on an LED led
screen through the control system;
2. The traditional signal acquisition card is poor in its image processing effect, which will have the image
definition suffer from bigger loss during signal format conversion;
3. The LED large-screen control system can only capture and display the images at the corresponding pixels on
the LED led screen, while some users need casual display of partial or complete computer desk pictures freely at the
scene;
4. With the constant decrease of the LED screen spacing and the constant increase of the on-screen pixels, the
era will no longer exist for a single loaded card to display a single frame on a single display screen and more
application and display demands will be highlighted, so the LED large-screen control system can not properly satisfy
customer's needs unless better cooperation is available with other peripheral device.
For the above problems, our company has independently researched and developed many video processing
products. Our products have integrated advanced control and image processing technology, not only able to achieve
rapid and stable signal switching but also able to complete multi-layer processing of images. In addition, such
products can be controlled and operated simply and conveniently through the device keyboard and PC.

VI. Wiring and installation
Wiring diagram
Installation steps
1. First of all, it should be ensured that the graphics card can directly control the transmitter card and the led
screen can display images normally when the video processor is not used;
2. Then complete wiring as shown in the diagram, connect the DVI interface of the graphics card to the DVI-IN
port of the video processor and then connect the DVI-OUT port of the processor to the transmitter card;
3. After correct wiring is ensured, power on to enable the video processor.
Note: To facilitate customers’ flexible and convenient operation, the processor can accommodate the transmitter
card, namely, the transmitter card can be installed in the processor and powered on by the processor, which thus has
eliminated the limitation that the transmitter card must be powered on by a desktop. The installation method is
detailed as follows:
①Remove the anchorage corner on the transmitter card;
②Unscrew and pull out the knobs on the rear panel, and then remove the temporary baffle;
③In the processor, there will be a four-wire small plug reserved corresponding to the wire slot on the
transmitter card; connect them and fix the transmitter card to the video processor;
④Fit the drawer box again in place and then just short-circuit the upper and lower DVI interfaces.

The setting method depends on the following four kinds of circumstances:
1. Atransmitter card has one frame enabled;
2. Atransmitter card has two frames enabled;
3. Two transmitter cards have one frame enabled;
4. Two transmitter cards have two frames enabled.
Here follow the detailed method for debugging under such four kinds of circumstances.
1. One transmitter card has one frame enabled;
Step 1: Click on “MENU” to enter the “Main MENU” interface.
Note: Turn the knob and you can select different functions; click “OK” to confirm the selected function.
Step 2: Click “Device Mode” to enter the interface for device mode options and select “Copy Mode”.
Step 3: Click “OK” to enter the “Out Format” interface, and if the led screen pixels are fewer than 1920 x 1080,
select the first item “Not Change” but if the led screen pixels are more than 1920 x 1080, select the second item
“Change” to enter the “Out Format” interface and then select a resolution larger than the on-screen pixels.
