The diagram above illustrates a typical installation with a B-500-MTRX-230 where all of the equipment is being
controlled by IR remotes in each output zone.
•
In each room with a connected display, an entry-level universal IR remote is being used to control the display
and sources in use. Custom programming set up in each remote by the installer sends IR commands out of the
remote meant for the display device in the room, the sources, and the matrix switcher simultaneously. The
matrix commands are programmed to be sent automatically as needed so the end user only has to 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 20 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-500-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 satellite box while
allowing other less-used sources to connect to any output.
