2.2. Wiring
1. Connect the HDMI sources (such as PC) to the HDMI IN 1-4 ports.
2. Connect HDMI display device (such as TV, projector, LED/LCD display) to
the HDMI OUT 1-2 ports.
3. Connect HDBT receivers (such as SCT-HDBT3KVM-TRX) to HDBT OUT
ports, and connect displays to the receivers.
4. Connect HDBT receivers (such as SCT-HDBT3KVM-TRX) to HDBT OUT
ports, and connect displays to the receivers.
5. Connect USB host PCs to USB HOST 1-4 ports of the device, and connect
USB devices (such as USB camera, Keyboard & Mouse) to USB 1-1/2,
USB 2-1/2 ports of the device and USB ports of the connected HDBT
receivers.
Note:
a) If the connected HDBT receiver is connected to multiple USB devices
or high-power USB devices, users need to connect a separate power
supply to the receiver.
b) By default, USB control is in sync mode, USB Host 1-4 ports are bound
with HDMI IN 1-4 respectively. When select one source from HDMI IN
1-4 for HDMI/HDBT OUT 1 or HDMI/HDBT OUT 2, the USB devices
connected to USB DEVICE 1-1/2 ports and HDBT receiver 1 or USB
DEVICE 2-1/2 ports and HDBT receiver 2 will be connected to the
corresponding USB host bound with the selected source.
c) Through API commands and Web UI, USB Control can be set to
independent mode and users can set USB devices to be connected to
any USB host. For example, select HDMI IN 1 as input source for
HDMI/HDBT OUT 1. Users can connect USB devices connected with
USB DEVICE 1-1, 1-2 and HDBT receiver 1 to any USB HOST such as
USB HOST 2. (Detail information, please refer to the separate
document “API Command Set_SCT-MXKVM42-H2U3” or “Web UI
Control” section)

6. Connect an audio receiver such as an amplifier) to AUDIO OUT port.
7. Connect for additional control options:
IR Control:
a) Using the provided IR remote directly point to the IR window to
control the matrix. (Detail information, please refer to “IR Remote
Control” section)
b) Connect IR receiver cable to IR IN 1/2 port of the matrix, connect
IR emitter cable to HDBT receiver 1/2, then users can use the
corresponding display remote to control the display connected
with HDBT receiver 1/2 at matrix side.
RS232 Control: Connect to a control PC or control system for RS232
serial control.
LAN Control:Connect LAN port of the matrix to a local network with
DHCP server, and connect a PC to the same network.
8. Connect to the provided power adapter to the matrix (With one-way PoE
function, the matrix can supply power for the connected HDBT receivers).

display and select input source for output 1 and output 2..
Turn on a CEC-enabled display device
Select the previous source input
Select a specific source input
Select the next source input

Note:
1. As the internal battery inside the remote control of our device is packaged
by insulation slice, please remove the insulation slice before use.
2. Please make sure that the remote is pointed directly at the IR receiver
window.
System Code Switch
The IR Remote provided with the Matrix is shipped in “00” IR system code. In
the event that Remote’s IR signal interferes with IR devices, e.g., TV, DVD
player, the Remote can be switched to “4E” code by short pressing the System
Code Switch on the Remote panel. At the same time, you must redefine the IR
system code of the Matrix using the API command.

HDMI2.0 KVM Matrix Switcher

4. Serial Port Operation
4.1. RS232 Control
Advanced users may need to control the matrix through RS232 serial
communication. Connect a control PC or control system to the RS232 port of the
Matrix. API command for RS232 control is available in the separate document
“API Command Set_SCT-MXKVM42-H2U3”. A professional RS232 serial
interface software (e.g. Serial Assist) may be needed as well.
Before executing the API command through RS232 serial connection, please
ensure RS232 interface of the device and the control PC are configured
correctly.
Parameters Value
Baud Rate 115200 bps
Data Bits 8 bits
Parity None
Stop Bits 1 bit
Flow Control None
4.2. Serial Command Routing
The matrix supports serial command routing function to HDBaseT receivers
from matrix LAN port.
1. Users can send commands and receive responses through matrix LAN port
to HDBT receiver connected 3rd-party devices.
2. Each HDBaseT output has a dedicated TCP/IP port on the matrix.
a) 5001 - serial routing TCP/IP port for HDBaseT output1
b) 5002 – serial routing TCP/IP port for HDBaseT output2
3. API commands are complete transmission, and not need to add extra
terminator. For example, when matrix IP is 192.168.0.100, all data that goes
to 192.168.0.100 port 5001 will also output from RS-232 port of matrix

HDMI2.0 KVM Matrix Switcher
14
HDBT output1 receiver.
4. When using serial command routing, the default values of serial connection
are as follows:
Parameters Value
Baud Rate 9600 bps
Data Bits 8 bits
Parity None
Stop Bits 1 bit
Users can use matrix API to change the serial parameters of 5001 or 5002
port independently according to different connected devices, the command
is as follows:
SET UART_CFG prm1 prm2 prm3 prm4 prm5<CR><LF>
Description:
prm1={5001, 5002};
prm2={9600, 19200, 38400, 57600, 115200};
prm3={7, 8};
prm4={none, odd, even};
prm5={1, 2};
<CR><LF> denotes a carriage return or a line feed.
Note: when sending the SET UARG_CFG API, it should be sent to matrix
TCP/IP port 23.

5. Web UI Control
The Web UI designed for the matrix is available for basic controls and advanced
settings of the device. The Web UI can be accessed through a browser with
latest version, e.g. Chrome, Firefox, Safari, Opera, IE, etc.
5.1. Get Access to the Web UI
1. Connect the LAN port of the matrix to the local area network, and connect
your PC to the same network (The default IP mode is DHCP, please ensure
the local area network is connected with a DHCP server).
2. Get IP address through API commands (see the separated document “API
Command Set_SCT-MXKVM42-H2U3”) or other tools such as
SmartSetGUI to get IP address.
3. Input the IP address obtained in step 2 in your browser and press Enter.
The following window will display.
4. Input the login password and click “Login”. The default password is “admin”.
