Initial Screen Configuration

If the LED screen, cabinets, data flow and the number of cabinets loaded by Ethernet ports can meet the following requirements, you can configure the screen via the device front panel menu; otherwise, screen configuration in VMP will be your ideal choice. Screen: The LED screen must be a regular screen. Cabinet: The cabinets must be regular ones of the same size, and function well. Data flow: The data must run in the same way for all Ethernet ports and the data flow must be one of the
followings. The starting position of the data flow is the first cabinet of Ethernet port 1, and the connections are made in sequence according to the serial number of the Ethernet port.
Number of cabinets loaded by Ethernet ports: If n ports are used to load the cabinets, the number of cabinets loaded by each of the first (n­1) ports must be the same and the integral multiple of the number of cabinet rows or columns, and it must be greater than or equal to the number of cabinets loaded by the last port.

5.1.1 Set Input Source
Select the desired input source and complete the related settings, such as resolution and frame rate. If the resolutions of the input source and screen are the same, the image can be displayed pixel to pixel. A lower frame rate may result in image flickering at low refresh rate, while a higher frame rate helps stabilize the display image.
Note Input source settings are required for screen configuration in the Send- Only Controller working mode and not required in the All-in-One Controller mode.
On the main menu screen, choose Input Settings to select a video source.

Ethernet Port Load Capacity

When Working with A10s Pro Receiving Card

The formula of calculating the load capacity per Ethernet port and the detailed parameters are as follows. 8bit: Load capacity × 24 × Frame rate < 1000 × 1000 × 1000 × 0.95 10bit: Load capacity × 32 ×Frame rate < 1000 × 1000 × 1000 × 0.95

Note
The maximum load capacity is only achieved when the load width of a single port is 128 pixels or more. If the load width is less than that, the load capacity will be reduced accordingly, calculated as (128 – load width) × load height.
