Installation and Wiring

Warnings:

• Before wiring, disconnect the power from the device.
• During wiring, connect and disconnect the cables gently.

To install the device in a suitable location, perform the following:

1. Attach the installation bracket to the enclosure using the screws provided. The bracket is attached to the enclosure as shown.
2. Repeat steps 1-2 for the other side of the device.
3. Attach the brackets to the surface you want to hold the device against using the screws (not included).

Wiring

1. Connect the HDMI sources (such as PC) to the HDMI IN 1-4 ports.
2. Connect an HDMI display device (such as a TV, projector, LED/LCD) to the HDMI OUT port.
3. Connect an HDBT receiver (such as SCT-HDBT3KVM-TRX) to the HDBT OUT port, and connect the display to the receiver.
4. 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&2, and USB ports of the connected HDBT receiver.
   Note:
   • 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.
   • By default, USB control is in follow mode, USB Host 1-4 ports are bound with HDMI IN 1-4 respectively. When selecting 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.
   • 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 an input source for HDMI/HDBT OUT. Users can connect USB devices connected with USB DEVICE 1&2 and HDBT receivers to any USB HOST such as USB HOST 2. (For detailed 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:
     • Using the IR remote directly point to the IR window to control the switcher. (For detailed information, please refer to the “IR Remote Control” section)
     • Connect the IR receiver cable to the IR IN port of the switcher, connect the IR emitter cable to the HDBT receiver, and then users can use the corresponding display remote to control the display connected with the HDBT receiver on the switcher side.
       • RS232 Control: Connect to a control PC or control system for RS232 serial control.
       • LAN Control: Connect the LAN port of the switcher to a local network with a DHCP server, and connect a PC to the same network.
7. Connect to the provided power adapter to the switcher (With a one-way PoE function, the switcher can supply power for the connected HDBT receiver).
8. Power on all attached devices.

IR Remote Control
The HDMI2.0 KVM Switcher comes with an IR remote control for convenient switching. Follow these steps to use the remote control:

1. Point the remote control towards the switcher.
2. Press the desired input source button on the remote control to switch between connected devices.

The remote-control handset can be used to turn on and off a CEC-enabled display and select an input source for output.

Note:

1. As the internal battery inside the remote control of our device is packaged with an 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 the above figure can’t be used to control the switcher.

System Code Switch
The IR Remote provided with the switcher is shipped in the “00” IR system code. If the Remote’s IR signal interferes with IR devices, e.g., TV, or DVD player, the Remote can be switched to the “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.

Serial Port Operation

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 the RS232 serial connection, please ensure the RS232 interface of the device and the control PC are configured correctly.

The HDMI2.0 KVM Switcher also supports serial port operation. Please refer to the user manual for detailed instructions on using the serial port functionality.

Serial Command Routing
The switcher supports serial command routing function to HDBaseT receivers from the switcher LAN port.

1. Users can send commands and receive responses through a switcher LAN port to an HDBT receiver connected to 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 transmissions, and do not need to add an extra terminator. For example, when the switcher IP is 192.168.0.100, all data that goes to 192.168.0.100 port 5001 will also output from the RS-232 port of the switcher HDBT output receiver.
4. When using serial command routing, the default values of serial connection are as follows: Users can use switcher API to change the serial parameters of the 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.

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 the latest version, e.g. Chrome, Firefox, Safari, Opera, IE, etc.

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).
2. Get IP address through API commands (see the separated document “API Command Set_SCT-SWKVM411-H2U3”) or other tools such as SmartSetGUI.
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”.
