7.2 IR Pass-through Control
The matrix switcher supports bi-directional IR pass-through, allowing the devices to be
controlled by both source and destination ends. This section provides connection and
switching examples to illustrate possible configurations.
7.2.1 Control Local Input Device from Remote
The same basic principles apply when controlling the local input device from the
remote location:
Control local input device through IR OUT port:
Example: Switch HDMI input 3 to HDBaseT output 4.
Connect an IR receiver to the
IR IN
port on the receiver, then connect an IR emitter to
the
IR OUT 3
on the matrix switcher. The third input source can be controlled through
its corresponding IR output port. The connection diagram shown as below:
