a). If n ports are used to load the screen, 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.
Example:
If all the 16 Ethernet ports are used to load the screen, the number of
cabinets loaded by ports 115 must be the same and the integral multiple of
the number of cabinet rows or columns. Therefore, you need to set only the
number of cabinets loaded by port 1 according to the actual situation. The
number of cabinets loaded by port 16 must be less than or equal to the number
of cabinets loaded by port 1.
b). For irregular screens, NovaLCT software must be connected to configure the screen.
c). During data flow settings, you can rotate the knob to select a target data flow pattern.
