USB devices (such as USB camera, Keyboard & Mouse) to USB 1&2, and

HDMI2.0 KVM Switcher
10
USB ports of the connected HDBT receiver.
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 follow 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, the USB devices connected to USB
DEVICE 1&2 ports and HDBT receiver 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. Users can connect USB devices connected with
USB DEVICE 1&2 and HDBT receiver to any USB HOST such as USB
HOST 2. (Detail information, please refer to the separate document
“API Command Set_SCT-SWKVM411-H2U3” or “Web UI Control”
section)
5. Connect an audio receiver such as an amplifier) to AUDIO OUT port.
6. Connect for additional control options:
IR Control:
a) Using the IR remote directly point to the IR window to control the
switcher. (Detail information, please refer to “IR Remote Control”
section)
b) Connect IR receiver cable to IR IN port of the switcher, connect
IR emitter cable to HDBT receiver, then users can use the
corresponding display remote to control the display connected
with HDBT receiver at switcher side.
RS232 Control: Connect to a control PC or control system for RS232
serial control.
LAN Control:Connect LAN port of the switcher to a local network

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.
3. Other buttons (2 (ON/OFF) and 2 (1-4)) not marked in above figure can’t be
used to control the switcher.
System Code Switch
The IR Remote provided with the switcher 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 switcher using the API
command.

HDMI2.0 KVM Switcher

4. Serial Port Operation
4.1. RS232 Control
Advanced users may need to control the switcher through RS232 serial
communication. Connect a control PC or control system to the RS232 port of the
switcher. API command for RS232 control is available in the separate document
“API Command Set_SCT-SWKVM411-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 switcher supports serial command routing function to HDBaseT receivers
from switcher LAN port.
1. Users can send commands and receive responses through switcher LAN
port to HDBT receiver connected 3rd-party devices.
2. Each HDBaseT output has a dedicated TCP/IP port on the switcher.
5001 - serial routing TCP/IP port for HDBaseT output
3. API commands are complete transmission, and not need to add extra
terminator. For example, when switcher 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
switcher HDBT output receiver.

HDMI2.0 KVM Switcher
14
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 switcher API to change the serial parameters of 5001 port
independently according to different connected devices, the command is as
follows:
SET UART_CFG out prm1 prm2 prm3 prm4<CR><LF>
Description:
out={5001 | UART1};
prm1={9600, 19200, 38400, 57600, 115200};
prm2={none, odd, even};
prm3={7, 8};
prm4={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 switcher
TCP/IP port 23.

HDMI2.0 KVM Switcher

5. Web UI Control
The Web UI designed for the switcher 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 switcher 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).
