5.2.2. Force Carrier
a)
An IR signal received by the Matrix Switch IR In port, which is coming from the
HDBT Receiver with a connected IR sensor, will only be transferred to the Matrix
Switch IR Out port, if the IR sensor connected to the HDBT receiver supports IR
carrier-wave.
b)
An IR signal received by the Matrix Switch IR In port, which is coming from a
directly connected IR sensor, will only be transferred to the Matrix Switch IR Out
port, if the IR sensor supports an IR carrier-wave.
Note: If the IR sensor connected to the HDBT receiver or directly to the Matrix Switch
does not support carrier-wave
, send the command “%0901.” to force enable infrared
carrier mode (force enable carrier-wave mode). Doing so allows the IR signal to be
transferred through the Matrix Switch to the IR Out port.
5.2.3. Control Far-end Displays while being near the Matrix Switch
Connect an IR sensor with IR carrier-wave to the IR IN port of the Matrix Switch. This
allows a user local to the Matrix Switch to control far-end displays via an IR remote.
In this case, the IR signal is transferred via HDBT over twisted pair to the remote
location. In the case of IR signals going from the source to sink direction, only the
corresponding IR OUT port (with the same port number as the IR In) can emit the IR
control signal to the remote display. Thus IR In 1 to HDBT Receiver 1, IR In 2 to HDBT
Receiver 2, and IR In 3 to HDBT Receiver 3.
See the figure below:

Note: The IR sensor connected to
IR IN
must support an IR carrier-wave signal.
5.2.4. Control Source Devices near the Matrix from a Remote location
The Matrix Switch supports two internal matrix switches, one for the Audio/Video signal
(AV Matrix) and one for the IR signal (IR Matrix). These two matrices can be switch
