Click [ Load ], choose the correct parameter file.

Click [ Send ], to send the loading parameter to the receiving card. 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 receiver card.

If each cabinet cannot display normally, then contact with the LED screen engineers.

5.2.3 Connection Parameters (Look from front)

You don’t need to set up the control area of each net port respectively under i series mode, but set up the connection relationship of the receiver card aiming at each net port loading via the sender card, and the software will auto calculate and set up the 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), how many pixels that one Receiver (Receiving card) manages in Width and Height (128*128 as an example), you will see LED display mapping area from the right side (Viewing from the front of LED display).


2)       Receiver Card Parameters Setting

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


There are two methods to set up:

1. Use mouse to select one by one

A. 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).

B. Click the Receiver (Receiving card) one by one until the last one for this network port loads.

2. Connection Pattern

A. Aiming at the LED screen with standard connection lines.

B. First set up the receiving card information according to the actual loading width and height (128*128 as an example).

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

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


3) Save to Receiver Cards & Save to Sender Cards

Set up all the receiving card parameters and connection line respectively, click [ Send ] to send the correct parameter to the receiving card, and the screen should display normally about this time.

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