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.
Output-1 Output-2 Output-3 Output-4
= LED ON = LED OFF
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 1 (”A” Example)
Output-1 Output-2 Output-3 Output-4
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 2 (”B” Example)
Output-1 Output-2 Output-3 Output-4
Output 1 is selected to 3A Output 2 is selected to 4B Output 3 is selected to 2A Output 4 is selected to 1A
Scenario 3 (Mixed Example)
