3.4 Connection Procedure
1) Connect HDMI sources (e.g. DVD) to HDMI inputs of the SUHM44HB with HDMI
cables.
2) Connect auxiliary audio sources to the AUDIO IN ports with audio cables.
3) Connect HDBaseT receivers (e.g. TPHD402PR) to the HDBaseT Output ports with
twisted pair.
4) Connect HDMI displays (e.g. HDTV) to HDMI outputs of the SUHM44HB or the
receivers with HDMI cables
5) Connect speakers/earphones to AUDIO output ports
6) Connect the RS232 port of control device (e.g. a PC) to the RS232 port of either
SUHM44HB or far-end receivers. RS232 signal can be transmitted bi-directionally
between SUHM44HB and far-end receivers.
7) SUHM44HB can collect IR signal sent by the included IR remote via its built-in IR
sensor or through external IR receiver connected to the IR IN/ IR EYE/ IR ALL IN
port. The IR signal can be transmitted bi-directionally between SUHM44HB and
far-end receivers.
8) Connect a DC 24V power adapter and the SUHM44HB.
Note:
1. Connect HDBT ports of SUHM44HB and far-end receiver with straight-through
cable.
2. IR receivers connected to IR IN& IR ALL 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 SUHM44HB and far-end receivers.
3.5 Connection with TPHD402PR
SUHM44HB boasts 4 HDBaseT output ports which support PoC solution. Connect the
HDBT output ports of SUHM44HB to HDBaseT Receivers supporting PoC (like
TPHD402PR) via twisted pair. Plug a power supply to the power port of SUHM44HB, the
HDBaseT Receivers will be energized synchronously with PoC solution.

4. System Operations
4.1 Front Panel Button Control
SUHM44HB provides with convenient front panel button control. Here we make a brief
introduction to the system operations.
4.1.1 Switching I/O connection
1) To convert one input to an output:
Operation: “input”+“output”+“ENTER”
Example: input 1 to output 2
Note: In default status, 4 IR OUT sockets correspond with 4 HDMI INPUTS. When you
convert an HDMI input to an output, the corresponding IR OUT will be switched
synchronously.
2) To convert an input to several outputs:
Operation: “input” + “output” + “output” +… + “ENTER”
Example: Switch input 2 to output 2, 4
3) To convert an input to all outputs:
Operation: “input” + “ALL” + “ENTER”
Example: Convert input 1 to all outputs
Note: Indicators of the pressed buttons will blink green for three times if the conversion
is done, then it will be off. If the conversion failed, they will be off immediately.
4.1.2 EDID Management
SUHM44HB features EDID management to maintain compatibility between all devices.
It can be controlled via EDID learning and EDID invoking.
EDID Learning (from output):

One input port learns the EDID data of one output port
Operation: Press “EDID”, “INPUTS”+“OUTPUTS”+“ENTER”.
Example: Input 2 learns EDID data from output 4
All input ports learn EDID data from one output port
Operation: Press “EDID”, “ALL”+“OUTPUTS”+“ENTER”
Example: All input ports learn EDID data from output 4
Note: Indicators of the pressed buttons will blink green for three times if the conversion
is done, then it will be off. If the conversion failed, they will be off immediately.
EDID invoking:
There are five types of embedded EDID data. The chart below illustrates the detailed
information of the embedded EDID data:
No.
EDID Data
1
1080P 2D 2CH
2
1080P 3D 2CH
3
1080P 2D Multichannel
4
1080P 3D Multichannel
5
3840x2160 2D（30Hz）
Press and hold “EDID”for 3 seconds to enter EDID invoking mode, in this mode, use
output buttons 1/2 to switch among the 5 embedded EDID data. Then press “ENTER”to
confirm invoking.
Format: Press and hold “EDID”for 3 seconds, “INPUTS”+“OUTPUTS 1/2”+“ENTER”.
Operations:
Invoke embedded EDID data for one input
Operation: Press “EDID”(hold for 3 seconds to enter in EDID setting status),
“INPUTS”+“OUTPUTS”+“ENTER”.
Example: Set the EDID data of INPUT 2 to the forth type of embedded EDID data:

Press (hold for 3 seconds) or to switch to the
4th EDID data .
Note: If the conversion is successful, indicators of the pressed buttons will blink green
for three times at normal speed; if the conversion failed, they will blink for three times
quickly.
4.1.3 Inquiry

indicators of input 1 and output 2 turn on and last for 3 seconds. Then output 2
corresponds to input 1.
4.1.4 Clear operation
When you switch output channel, learn EDID data, or set EDID data, press Clear button
to withdraw the operation before you press “ENTER”to carry it on. When you press it,
the matrix will return to the previous status.
4.2 IR Control
By using IR & HDBaseT transmission technology, the SUHM44HB has some functions
as follows:
1) Control far-end output device from local.
2) Control local input/output device remotely.
3) Control the SUHM44HB locally/remotely.
4.2.1 Usage of IR Remote
①Standby button, press it to enter/ exit standby
mode
②Input channels, range from 1~4 (buttons 5~8 are
not available), corresponding IR signal switched
synchronously when switching input channels.
③Menu buttons, ALL, EDID and CLEAR, same
with the corresponding front panel buttons.
Please refer to 4.1 Front Panel Button Control for
details.
④: Navigation buttons.
ENTER: Confirm button.
⑤OUTPUTS (buttons 5~8 are not available)
In normal mode: output channel selection
buttons, each channel has 1 IR IN, 1 HDBaseT, 1
RS232, and 1 AUDIO outputs, and channel 1~4
have HDMI outputs.
In EDID invoking mode: press button 1/2 to
switch among the 5 embedded EDID data

Note: With this IR remote, SUHM44HB can be controlled by the built-in IR, the extended
IR receiver connected to the “IR EYE”/”IR ALL IN”and the IR receiver on the far-end
receiver.
4.2.2 Force Carrier
a) Only if the IR receiver connected to HDBaseT receiver is with IR carrier, can the
received IR signal be transferred to IR OUT port of the matrix.
b) Only if the IR receiver connected to IR ALL IN port of the matrix is with IR carrier,
can the received IR signal be transferred to IR OUT port of the matrix.
If the IR receiver connected with HDBaseT receiver or IR ALL IN port of the matrix is
not with IR carrier, send the command “%0901.”to enter infrared carrier enforcing
mode, and then IR signal can be transferred to IR OUT port.
4.2.3 Control Far-end Device locally
Connect an IR receiver to IR IN/ IRALL IN on the switcher, and use the IR Remote of
far-end device to control the device locally.
1 to 1: (through IR IN)
Connect an IR receiver with IR carrier to the IR IN port of SUHM44HB; 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.

The IR signal is sent by corresponding IR remote, then it is transferred to HDBaseT
receiver, then to corresponding zone of the matrix through the twisted pair, finally it is
transferred to IR OUT port and received by controlled device.
Switching Operation: (4 IR IN ports correspond with 4 HDMI input ports separately in
default mode.)
a) Sending command (reference to 4.3 RS232 Control): [x1]R[x2].
x1: Corresponding to the 4 IR OUT ports of the matrix, the IR transmitter connected
to this port can be placed at IR receiving area of output device or SUHM44HB
itself.
x2: Corresponding to the zone (receive IR signal from HDBaseT receiver with IR IN
port connects with IR receiver) number of SUHM44HB.
Example: Send command “3R2.”to transfer IR signal received from zone 2 to IR
OUT port 3.
4.3 RS232 Control
4.3.1 Connection with RS232 Communication Port
Except the front control panel, the SUHM44HB can be controlled by far-end control
system through the RS232 communication port. This RS232 communication port is a
