5 1 Selected Input LED Indicator Each of the 4 outputs has an 4 LED array to indicate which source is currently selected on the 8x4 Matrix for HDMI. Each of the inputs can accept up to 2 sources (A and B) and the LED array will behave in 2 modes to indicate which of the two sources for input is selected.
6 How to Connect the 8x4 Matrix for HDMI 1. Connect up to 8 HDMI source devices to the 8x4 Matrix for HDMI using the included HDMI cables. NOTE: Please be aware that each input has two available HDMI ports and that only one will be active at any given time.
7 LED ARRA Y 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.
8 The RMT -16IR remote control will allow the user to select which source will be routed to which output. Each of the 4 outputs are assigned a group of 4 buttons that will correspond to the 4 source inputs.
