6.2 IR Control
The HDBaseT 4x4 matrix switcher can be controlled by its built-in IR receiver, through the IR EYE
port by connecting with extended IR receiver or controlled remotely by a far-end IR device through
one of its receivers. By using IR & HDBaseT transmission technology the HDBaseT 4x4 matrix
switcher has the following features:
Control far-end output device from local.
Control local input/output device remotely.
Control the HDBaseT 4x4 matrix switcher locally/remotely.

6.2.1 IR Remote Operation
Input channels, range from 1~4, IR signal
switched following HDMI signal
correspondingly.
Menu buttons, AV and ALL buttons have
the same function as the front panel.
THROUGH: To transfer the signals directly
to the corresponding output channels
Example: Press “3”, “THROUGH”, the result
will be IN 3OUT 3. Press “ALL”,
“THROUGH”, the result will be: 11, 22,
33, 44
Output channels, range from 1~4.
Each channel has 1 IR IN, 1 COAX, 1
HDBaseT, 1 RS232, and 1 AUDIO outputs,
and channel No.1 & No.2 has 1 HDMI
output.
Standby button, press it to enter in standby
mode.

6.2.2 IR Operations
IR Matrix Switching
By using the 4 “IR OUT” ports and the “IR IN” ports of the far-end receivers, the HDBaseT Matrix can
be used as an IR router. Commands can be sent to the Matrix for the IR to follow the video or to
switch separately.
The IR signal received by an HDBaseT receiver is transmitted to a selected IR port (IR OUT) on the
matrix switcher received by a controlled device.
See figure below:
Switching Operation:
a) Sending command [x1]R[x2]. (reference to 6.3 RS-232 Control):
x1: Corresponds to one of the 4 IR OUT ports of the matrix
x2: Corresponding to an HDBaseT receiver
Example command: “3R2.”transfers IR signal received from Receiver 2 to IR OUT port 3.
b) Using IR remote: Input channelbutton IROutput channel
Example Press buttons “3”, “IR”, “1”in order to transfer IR signal received from Receiver 3 to IR
OUT port 1.
Note: Multiple receivers cannot be selected to the same IR output.

TEK-MHD44TP 4x4 HDBaseT Matrix
TEKVOX, INC. 9 www.tekvox.com
210.348.6565
IR Carrier Enforcing:
a) IR carrier must be present on the HDBaseT receiver for the IR signal to be transferred to the IR
OUT port of the matrix.
b) IR carrier must be present on the IR ALL IN port of the matrix for the IR signal to be transferred to
the IR OUT port of the matrix.
c) If the IR receiver is connected with an HDBaseT receiver or IR ALL IN port of the matrix is not with
IR carrier, you need to send the command “%0901.”to transfer the IR signal to IR OUT port.
Control far-end output device from local
To control a remote display from the local IR receiver, IR carrier must be present on the IR ALL IN
port. The IR signal is transferred to the corresponding zone connected with an HDBaseT receiver that
has an IR transmitter. When the IR receiver is connected to IR ALL IN port, the IR signal can be
transferred to all 4 IR transmitters connected with HDBaseT receivers.
See figure below:

Control far-end device through IR ALL IN port
The IR signal received from IR ALL IN port will be transmitted to all the four far-end HDBaseT
receivers connected to HDBaseT ports on the matrix switcher.
See figure below:

TEK-MHD44TP 4x4 HDBaseT Matrix
TEKVOX, INC. 11 www.tekvox.com
210.348.6565
Control local device from remote
User can control local devices such as Blu-rays or the HDBaseT Matrix remotely. When using the IR
signal received from the HDBaseT receiver will be transmitted to the corresponding IR OUT port of
the HDBaseT 4x4 matrix switcher.
See figure below:
Controlled by a Third-party IR Control Device
Use the included IR converting cable (see as below) to connect the HDBaseT matrix to a third-party
remote controller via a direct connection. Connect the red end to IR Input port on the HDBaseT
matrix and the black end to IR Output port of the third-party control device. This allows the IR signal
to be transmitted through the receivers to control a remote device.

/%[Y]/[X]:[Z].
HDCP management command. [Y] is for input
(value: I) or output (value: O). [X] is the number of
one port, if the value of X is ALL, it means all ports.
[Z] is for working status (Value: 1 or 0).
Y=I & Z=1, means the input port is compliant with
HDCP.
Y=O & Z=1, means output with HDCP.
Y=I & Z=0, means the input port is not compliant
with HDCP.
Y=O & Z=0, means output without HDCP.
