7. IR Control System
The product is not only a matrix switch but also an extender. It supports bi-directional IR
control. When the matrix is connected to a HDBaseT Receiver through Cat 5e/6/7 cable,
you can control the remote display device (HDBaseT) or input source device (Matrix)
through IR signal transmission. The IR signal transmission method is different using the
method from Matrix (local) to HDBaseT Receiver (remote) and from HDBaseT Receiver
(remote) to Matrix (local).
At the Matrix end (Local end): the IR signal is one-to-one transmission. It means that the
IR INPUT 1 port signal of the Matrix will emit to IR output port of the HDBaseT Receiver 1
and the IR INPUT 2 port signal of the Matrix will emit to IR output port of the HDBaseT
Receiver 2 etc. It doesn’t follow the video switch to change. IR All input port signal of the
Matrix will emit to all IR output port of HDBaseT receiver simultaneously. Please see the
following connection diagram.
