IR IN
7 x IR IN: Connect with IR receiver, fixed IR input for
the output, cannot be switched separately. It makes
up an IR bi-directional transmission with the IR OUT
on the corresponding HDBaseT receiver.
1 x IR EYE: Connect with extended IR receiver, use
the IR remote to control the Matrix Switcher.
④
IR OUT
8 x IR OUT: Plug in IR emitters to deliver the IR signal
sent from the far-end receivers connected to the
HDBaseT ports. These IR OUT sockets make up an
IR matrix with the IR IN sockets on the far-end
receivers, and all can be switched simultaneously with
the AV signal, or separately from switching. In default
setting, the 1~7 IR OUT corresponds with the 1~7 IR
IN, i.e. IR OUT1 - IR IN1, IR OUT2 - IR IN2, …IR
OUT7 - IR IN7.
1 x IR ALL OUT: Plug in IR emitter to deliver the IR
signal to control input source device form any of
far-end receivers.
⑤
CONTROL
RS232: Serial port for unit control, 3-pin pluggable
terminal block, connects with control device (e.g. PC).
TCP/IP: RJ45 port. Connect with PC for Web-based
GUI control.

System Diagram
Note:
Connect HDBT ports of Matrix Switcher and far-end HDBaseT Receivers with
straight-through cable.
IR receivers connected to IR IN should be with carrier. If not, send
command %0900. or %0901.to activate native carrier mode or force carrier mode
in the IR matrix launched between Matrix Switcher and far-end HDBaseT
Receiver.

By using IR pass-through & HDBaseT transmission technology, the 4K HDBaseT
Matrix Switcher has some functions as follows:
Control far-end display.
Control local source device.
Control far-end display
Connect an IR receiver with IR carrier to the IR IN port of the Matrix Switcher; users
can control far-end output displayer via its IR remote from local. In that case, the IR
signal is transferred via twisted pair. Only the corresponding IR OUT port can emit
control signals to the remote display.
See the figure below:
Note: The IR receiver connected to IR IN must be with IR carrier

OUT port of the switcher, and use the IR Remote of local source to control the
device remotely.
1 to 1:
Connect an IR receiver to IR IN on far-end HDBT receiver, and an IR Emitter to IR
OUT port of the switcher. Use the IR Remote of local source to control the device
remotely. See below:
Note: Send command “%0901.” to enter infrared carrier enforcing mode if the IR
Receiver connected to IR IN of the receiver is not with carrier.
