An entry-level universal IR remote is being used to control the display and sources from each room with an
HDBaseT receiver. Custom programming by an installer enables the remote controllers to send IR commands
out to the display in the room, the sources, and the matrix switcher simultaneously. The matrix commands can
be programmed so the end user has to simply select the source they want to watch.
•
To make this system work seamlessly, two advanced IR options have been enabled in the matrix switcher
Configuration Utility Other Settings menu: IR Source Routing and IR Matrix Control From Room.
• IR Source Routing allows the commands from the room to be routed directly to the source selected to be
displayed in the room. This simplifies IR routing because only one flasher has to connect to the source.
• IR Matrix Control sets the matrix switcher so that any command sent from any HDBaseT output to control
the matrix is automatically received internally, eliminating the need for an external connection back to
the matrix for control. See Section 8: Advanced Setup Using the Configuration Utility on page 24 for more
information on changing these settings.
•
When the commands are sent, the display device is controlled directly by the remote. The commands for the
matrix switcher and sources are picked up by the IR receiver connected to the B-520-RX-230-IR and sent back
to the correct IR Output to Source port and to the matrix.
•
When the system is in use, if two outputs are connected to the same input, the source will change on both
outputs with any command sent since it can't send two HDMI streams at once. This must be considered when
deciding on the sources to connect for distribution.
Example: In a home with five displays connected, if users in every room want to watch satellite on different
channels, there must be five satellite receivers set up as sources. With custom programming, each output can be
programmed to use only one of the satellite source inputs, giving each output a dedicated cable box while allowing
other less-used sources to connect to any output.
7. EDID CONFIGURATION
The displays used within an installation usually vary from room to room, and some may not support all resolutions
available from a source. It is necessary to make sure sources will provide a video and audio format compatible with
all connected displays programmed to use them. To accomplish this, the B-520-MTRX-230-8x8 /
B-520-MTRX-230-6x4+2 includes built-in EDID management for each source input. The stored EDID is per
source, so all display locations will see the same resolution and have the same audio format when that source is
selected.
Note: Source is only able to output one video resolution and one audio format.
Note: The default EDID for each input is always 1080p with 2 channel stereo audio, since this format is accepted
by most displays with no issues.
The following sections explain configuring EDIDs via the included IR remote. Before configuring the EDID, be
sure to refer to the source and display manuals for available features and resolutions for each device. For more
information about using the included remote, see Section 10.1 IR Remote on page 25.
While all EDID configurations are available via the remote, the Configuration Utility can be used for faster setup.
Download the Configuration Utility and manual on the Support tab at the product page for the
B-520-MTRX-230-8x8 / B-520-MTRX-230-6x4+2 at www.SnapAV.com.
What is EDID? EDID, or Extended Display Identification Data, is a stream of information sent from a display to a
source when the two devices are connected to tell the source what video and audio formats the display can use.
This prevents sources from outputting media that won't work with the display.
7.1. Source Setup
Check each source and confirm that the audio format and video resolution are set so that they will change based
on the EDID. Normally this setting is called Auto or similar.
Note: EDID setup is not required if the source supports setting one fixed video resolution and audio format.
