LED ARRAY
The LED array on the 8x4 Matrix for HDMI is designed to inform the user of the current source to output routes. Each output has a 4 LED array that will indicate which source is currently selected. Each input can accept two sources and therefore the LED array will act differently according to which input, “A” or “B”, is active for each.
•An input’s “A” source will be indicated by an single LED (the selected “A” input) that is ON.
•An input’s “B” source will be indicated by the reverse; a single LED will be OFF (the selected “B” input) while the remaining 3 LEDs will be ON.
The examples below will show some scenarios to illustrate the LED array functionality. Please note that it is not possible to have both “A” and “B” inputs active at the same time for any given input.

| Scenario 1 (”A” Example) |
| |
| ||||
Output 1 is selected to 1A | Output 2 is selected to 2A | Output 3 is selected to 3A | Output 4 is selected to 4A | |
|
| Scenario 2 (”B” Example) |
| |
| ||||
Output 1 is selected to 1B | Output 2 is selected to 2B | Output 3 is selected to 3B | Output 4 is selected to 4B | |
|
| Scenario 3 (Mixed Example) |
| |
| ||||
Output 1 is selected to 3A | Output 2 is selected to 4B | Output 3 is selected to 2A | Output 4 is selected to 1A | |
