7.10. IR Application Diagrams
7.10.1. IR Pass-Through from Control System
The diagram above illustrates a typical installation with a B-500-MTRX-230-4X4 where all of the equipment is being
controlled by a control system that uses RF (Radio Frequency) remotes in each output zone.
• The RF remotes transmit commands back to the control system which then sends commands to each device being
controlled. Custom programming by the installer sets the control system up to automatically switch inputs and
outputs in the matrix switcher as needed, so the end user only has to select the source they want to watch.
• Each display (only one is pictured for reference) requiring IR control is connected to the system via the HDBaseT
output of the matrix switcher. Cat5e/6 cable connects to a B-500-RX-230-IR Receiver, which is attached to the
display via HDMI for signal. An IR flasher connected to the IR flasher port sends the IR commands to the display.
Sources are directly controlled by the control system.
• IR control for displays is routed from the control system to the matrix switcher using 3.5mm mono mini cables
plugged into IR INPUT TO ROOM ports. The commands pass from a matrix switcher port to the HDBaseT output of
the same number. In the diagram the mono cable used to send commands to the output 4 zone is plugged into IR
INPUT TO ROOM port 4. This allows discrete control of each display connected, even if they are models with the
same codes.
• Some displays and projectors can be controlled by other methods than IR. The projector pictured features IP control,
so it is receiving commands from the control system over an Ethernet connection. An HDMI cable is connecting it to
the matrix switcher output since it is installed close enough to the equipment and requires no IR flasher.
• 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 four displays connected, if users in every room want to watch satellite on different
channels, there must be four 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.
