    4. Ethernet Cable

    Connect receiver cards and Q7H by using Ethernet cable (Note: The Ethernet cable must be CAT5E or CAT6)

  3. Operating Environment

      1. Computer configurations

        • CPU Frequency >= 2.0GHZ

        • Host Memory >= 1G

        • Graphic card with DVI interface: Memory 512MB

          Computer configuration can be adjusted according to the actual situation. Adjustment mainly aims at total pixels of LED display, complex playing program and whether playing HD video or not. Please note that the PC’s graphic resolution should be equal to or more than LED display’s.

      2. USB driver installation

        There are two methods for installation USB driver.

        1Check ‘USB Drive For Sending Card’ when install the LEDVISION, as you can see in following picture.



        2Open the CD-ROM, find the file name of "USB driver for sending card" and double click it to install.

      3. Graphics Card Settings

        Select duplicate or extend in graphics card mode, and their difference is that led display show the contents consistent with computer in duplicate mode, while in extend mode show only the window you want to display. (As shown in Fig.4-2)



        How to change the mode, there have different ways in different computer. For example, WIN 7/8 system and NVIDIA graphics cards, please read the following settings ways.

        • The first way: Hold down the WIN and P keys at once, and select the mode as you want in the pop-up window



        • The second way: Right-click and select “screen resolution” to enter the page of “modify the display appearance”; if your graphics card is not NVIDIA and cannot find the setting interface please refer to the description of the graphics card.





  4. Parameter Configuration

First of all, please make sure the software in i Series Mode before setting.

Click the “Setting” > “Software Setting” to enter the Software Management window (Shown as Fig.5-1), change the mode by using password: 168.



4.1 Hardware Connection Check

Please make sure the hardware connection correct and software is in i Series Mode before setting.

      1. Detect Sender Cards

        Run software, click the “Control” > “Screen Management” to enter the Screen Management window, the Sender Mode select “By Sender Card”, Click “Detect Sender Cards”, the sender cards information will show in the interface, (as shown in Fig.5-2 )

        Please check the hardware connection if cannot detect sende



      2. Detect Receiver Cards

Select network port and click “Detect Receiver Cards”, the software will automatic acquisition the Receiver (Receiving card) quantity for each network port of the sending card. Please check cable if the numbers of receiving card are inconsistent with actual. (As shown in Fig.6-3)



    1. LED Screen Setting

      Click “Led Screen Setting” by using password: 168 to enter the Led Play Screen Setting interface, click “Advance Settings” (As shown in Fig.6-4)

      1. Sender Card Setting



        Sender Card Resolution: In general, it should be consistent with graphics cards

        Input Signal Information: Software will automatically collect parameter from the sender card.

        Advanced Settings: This feature is only for professional and technical personnel to set up special applications, nonprofessional personnel are not allowed to operate. It contains the following parameters setting in Advanced Settings.

        • 3D Setting: Q7H is no need to set this item because only for 3D Sender feature setting.

        • Write Logo: Can be written to the customer specified image such as logo, and display before the video signal is not input.

        • Zero Frame Delay: Enabled by the professional and technical personnel or it will display abnormally.

        • Auto Switch (DVI, HDMI): The transmitter only identifies the set of video signals when selected; the signal of the first access can be automatically identified when not checked.

        Otherwise, enter the following configuration:

        The first step: Click “Load” to select the correct parameter file for your LED display



        The second step: Click “Send” to send the parameter to receiver cards, at this moment, all cabinets should display normally (the picture between cabinets is not continuous but also as normal), then click “Save To Receiver”.

        Please contact display manufacturer of engineering and technical personnel if display abnormally.


      3. Connection Parameters (Look From Front)

In i Series Mode, LED screen just needs set up the Receiver (Receiving card) connection relationship for each network port of the sending card, the software will automatically calculate the network port control area. Specific setting as following:

  1. Receiver Lay out Setting

    Set how many Receiver (Receiving card) are used in Row Count and Col Count (6*6 as an example), how many pixels one Receiver (Receiving card) manages in Width and Height (64*64 as an example), in the software interface right you will see led display mapping area (Viewing from the front of led display). (As shown in Fig. 5-6)


    Fig. 5-6

  2. Receiver Card Parameters Setting

    Select corresponding “Sender No.” and “Port”, when conduct Receiver (Receiving card) connection. Configuration Receiver (Receiving Card) connection pattern for each port individually if more than one port are used. There are two methods to set up.

    Note: Set up connection Receiver (Receiving Card) must be based on fact.



    Select the connection pattern based on fact, and then select this port load Receiver (Receiving card) in the display mapping area. (As shown in 5-9)



    If some Receiver (Receiving card) manage different quantity of pixels from others, specific Receiver (Receiving card) Size in Width and Height can be set individually. (As shown in 5-10)



  3. Send to Receiver

After set up the Receiver (Receiving card) parameters and connection pattern for each network port of the sending card, LED display will available when click “Send”.

Please determine that no mistake then click “Send to Receiver” to save the parameter



in Receiver (Receiving card).
