Signal connection
The pixel data signal is passed from the LED controller to the LED screen through the signal cable. The individual LED
panels of the screen are connected in a daisy chain pattern. The LED controller must be configured to reflect the physical
connection pattern. (See LED controller documentation for details.)
The signal indicator (green) on the back of the panel flashes quickly (approx. every second) when a correct signal con-
nection is established. When no signal is detected, the indicator flashes slowly (approx. every 5 seconds).
It is highly recommended to use the same connection pattern for connect both signal and power. The following figure
shows an example of the recommended signal connection pattern.
