IR REMOTE DESCRIPTION RMT-8MIR Remote 1 2 1 Activity Indicator This LED will be activated momentarily each time a button is pressed. 2 Display and Source Selection Buttons These buttons are used to select which input source is routed to the HDTV display(s). Routing Sources to Displays Issuing a routing command is a simple process. There are a total of 8 buttons on the IR remote. Each set of four (4) buttons are grouped by color for easy navigation.
IR REMOTE DESCRIPTION The IR remote control will allow the user to select which source will be routed to which output. Each of the two (2) outputs are assigned a group of four buttons which correspond to the four source inputs. Please use the information below when selecting the desired source for each display.
IR REMOTE INSTALLATION Installing the IR Remote Battery 1. Remove the battery cover on the back of the remote. 2. Insert the included battery into the open battery slot. The positive (+) side of the battery should be facing up. 3. Make sure that both DIP switches are in the OFF position. 4. Replace the battery cover. The remote ships with 2 batteries. One battery is required for operation and the other battery is a spare.
IR REMOTE CONFIGURATION Setting the IR Remote Channel on the RMT-8MIR In the event that IR commands from other remote controls conflict with the supplied RMT-8MIR Remote, changing the remote IR channel will fix this issue. The RMT-8MIR Remote has a bank of DIP switches for setting the Remote IR channel. The DIP Switch bank on the RMT-8MIR is located underneath the battery cover.
CHANGING THE IR CHANNEL How to change the IR channel Use the following procedure to set the proper IR channel on the 4x2 Matrix for HDMI. 1 Press and hold the Out 1 button for 5 seconds to enter IR channel selection mode. The bank of blue LED indicators will now display the currently selected IR channel. 2 Press the Out 1 button to cycle through each IR channel. The currently selected IR channel will be indicated by a flashing blue LED.
IR EXTENDER INSTALLATION Using the IR Extender An optional IR Extender (Gefen Part No. EXT-RMT-EXTIR) can be used to extend the IR capabilities of the 4x2 Matrix for HDMI. One such application allows the Matrix to be hidden within or behind a cabinet (see illustration below). Simply connect the IR extender to the IR extender port (see page 4).
EDID MANAGEMENT What is EDID? The 4x2 Matrix for HDMI features automatic and manual EDID management to maximize compatibility of all attached devices. First it is necessary to understand EDID and what it is used for. EDID. What is it and what is it used for? Under normal circumstances, source devices will require information about a connected display device to assess what video resolutions and other features are compatible with the output device.
EDID MANAGEMENT EDID Mode Selection 1. EXTERNAL MODE: To use this mode, set the EDID Mode Switch on the front panel to the EXT position. In External EDID mode, the Matrix directly retrieves EDID data from each connected A/V display device and builds a new EDID. This new EDID is sent to the source device.
EXTERNAL EDID MANAGEMENT The 4x2 Matrix for HDMI features EDID Management. Before the source can send video or audio signals to the display, the source devices reads the EDID (Extended Display Identification Data) of each device connected to an output. The EDID contains information about what type of AV data that the source can send to each display. The 4x2 Matrix for HDMI routes multiple source signals to multiple output devices. This involves reading EDID data from more than one device.
EDID MANAGEMENT Audio Channel Selection The 4x2 Matrix for HDMI features a switch that will modify the supported audio formats listed in the pre-programmed EDID. This feature is useful for limiting the output of the source device to either 2 or multi-channel audio formats. NOTE: This selector switch will only affect the pre-programmed EDID in the INTERNAL (INT) EDID Mode. The 4x2 Matrix for HDMI can use either of the following settings for audio format support: 1.
