5. Parameter Configuration

Please make sure the correctness of the hardware connection before setting, use LEDVISION to detect sender and all receiving cards.

5.1 Detect Sender and Receiving Card

1. Run LEDVISION, click [Control][Device Information] to enter the Device Information window.




2. Click [Detect Senders] in [Sender]. Please check the hardware connection or the installation of relevant driver if cannot detect senders.

Select network port and click [Detect Receiver Cards] respectively, the software will automatically acquire the receiver card quantity of each network port of the sender. Please check corresponding cable if the numbers of receiver card are inconsistent with actual status.



5.2 LED Screen Setting

Click [Control][LED Screen Settings] and a Password Input box will appear. Enter the authorization password [168] to enter the LED Screen Setting interface, and set up “Sending Device”, “Screen Parameters” and “Receiver Mapping”.




5.2.1 Sending Device Setting

[Select Sending Device] for [Sender], and detect senders. Sending Device Setting includes 5 parts: Source Setup, Control Area, EDID, Other, Detect Receivers.


1. Source Setup

Signal Source

When the input signal source of X4e is normal, the upper right of the software interface will display the input signal information auto acquired via the software. Users can select specific signal source (HDMI/DVI/SDI1/SDI2/DP) according to needs in [Main]; If PIP mode has been open, users can also select specific signal source (HDMI/DVI/SDI1/SDI2/DP) in [PIP]. At the moment, the image of selected signal source will display in the Image View Area on the left of the software interface.





There are three output modes of main image and PIP in [Output Mode], users can select specific PIP mode based on the requirement, and conduct the operation like move, scaling and cropping on the main image and PIP image respectively.



In Image View Area, select the image that needs to be scaled, set X, Y, width and height of it in [Main] or [PIP], or you can click the white box in the bottom right corner of the image and drag it with the mouse, finally click [Save].



Select signal source of the image that needs to be cropped in Input Signal Area, click [Set] to enter the cropping interface.



In the cropping interface, check [Crop], and set X, Y, width and height in [Cropping Settings], then the cropping setting is auto saved.




Picture Adjustment

Click [Picture Adjustment], and enter the interface of picture adjustment. Check [Enable], and adjust hue, saturation, brightness compensation and contrast ratio of the whole image, then click [Save] to complete. After setting, you can click [Default Settings] to restore the default values of every parameter, that is, hue and brightness compensation default to 0, saturation and contrast ratio default to 100.





In [Preset], 16 preset parameters can be saved, and every preset parameter includes all parameter information of source setup (signal source, PIP, scaling, cropping, picture adjustment), users can directly load one preset parameter to display the image according to needs, and don’t need to set up all parameters again.

After completing setting up all parameters of source setup, select unnamed preset, click [Save] to save the parameter to sending device, and rename it; click [Load], send the parameter to receiving cards. At the time, the image should display on the basis of preset parameter.


2. Control Area

In Control Area, it displays the control area of each net port of X4e. Click [Import] and select correct parameter file, click [Save] to save parameters into corresponding sender; or set up the control area of each net port respectively (X, Y, Width, Height), click [Save].



Set sender resolution, the first one is the default as current resolution.



Click the dropdown button to display the resolution list to select the mainstream resolution, and you can also customize the sender resolution, by setting the width/height and frame rate.

Click [Save] after setting.


4. Other

Advanced Parameters Setting (Better graylevel on Low Brightness, Mapping from Sender, Device Name), Test Mode Selection, Factory Restore.


5. Detect Receivers

Detect receivers under each net port of X4e controller, and acquire relevant information about the receivers (Port, Index, Version, Run Time, Support Chips).


5.2.2 Screen Parameters Setting

Observe the display screen with single cabinet as a unit, and if all cabinets themselves could display normally {it is normal circumstance even the picture between cabinets is not continuous}, please ignore this step and directly go to the next step.

Otherwise, configuration must be done as follows:



Click [Load], choose the correct parameter file.

Click [Send], to send the loading parameters to the receiving cards. At the moment, each cabinet should display normally (it is normal circumstance even the picture between cabinets is not continuous), then click [Save to Receiver] to save the parameters to the receiving cards.

If each cabinet cannot display normally, you can conduct via the Advanced Settings (Module Information, Cabinet Setting, Performance Setting) or Intelligent Setting, and you can also contact with the LED screen engineers.

5.2.3 Receiver Mapping Setting

Users don’t need to set up the control area of each net port respectively, but to the connection relationship between the receiving cards under the network port loading via each sender, and the software will auto calculate and set up the port control area according to the connection relationship.

Detailed setting steps as follows:

1. Set up the quantity of receiving card

Set how many receiver (receiving card) that one port manages in Row Count and Col Count (6*6 as an example) according to the actual loading of LED display, you will see LED display mapping area from the right side (Viewing from the front of LED display).



2. Receiving Card Parameters Setting

Select the target sender and the net port from the left side, then select the corresponding cabinets within net port actual control area and set the connection lines in the mapping area.


There are two methods to set up:

Use mouse to select one by one

In the mapping area, select the first receiving card based on the actual connection of the net port (view from the front), and then set up the actual loading width and height of the target receiving card in the right side (128*128 as an example).

Click the receiver (receiving card) one by one, according to actual connecting line, until the last one for this network port loads.


Connection Pattern

Aiming at the LED screen with standard connection lines, firstly set up the receiving card information according to the actual loading width and height (128*128 as an example).

Select the connection line you want from the right side, then cover the corresponding area of net port loading in mapping area, finally complete setting.


Note: As the cabinets have multiple and different specification (that is the inconsistent capacity of the receiving card), you can select the different one to adjust separately after completing setting.


3. Send & Save to Receiving Card

After setting up all the receiving card parameters and connection lines respectively, click [Send] to send the correct parameter to the receiving card, and the screen should display normally at this time.

Then click [Save to Receiver] to save parameters to corresponding receiving card after confirming.
