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 re

IR CODE CONFIGURATION Why would I need to change the remote channel? In some instances, the 8x4 Matrix for HDMI may use IR codes that confl ict with other IR remote control devices. The unit may switch inputs when another brand IR remote control is used or the RMT-16IR may cause other brand IR controlled devices to behave unexpectedly. I am experiencing the issues listed above. What do I do? In these cases it is recommended to change the IR channel that the RMT-16IR remote control and the 8x

EDID MANAGEMENT FEATURE EDID. What is it and what is it used for? Under normal circumstances, a source device (digital and analog) will require information about a connected device/display to assess what resolutions and features are available. The source can then cater its output to send only resolutions and features that are compatible with the attached device/ display. This information is called EDID (Extended Display Information Data) and a source device can only accept and read one EDID
