3. System Connection
3.1 Usage Precautions
1. System should be installed in a clean environment, which should have a
proper temperature and humidity.
2. All the power switches, plugs, sockets and power cords should be insulated
and safe.
3. All devices should be connected before powered on.
4. System Diagram shown in this manual is for reference only; more specific
schemes depend on real-time applications.
3.2 Connection Procedures
Step1.Connect HDMI source device(s) (e.g. Blue-Ray DVD) to the “IN1” ~ “IN4” ports
of the SW-4X1SL18G via HDMI cable(s).
Step2.Connect HDMI display (e.g. HDTV) to “OUT” port of this switcher with HDMI
cable.
Step3.Connect an IR Receiver to the “IR IN” to control the switcher via IR Remote.
Step4.Connect the control device (e.g. PC) to the “RS232” port to control the switcher
via RS232 commands.
Step5.Plug a DC 5V power adapter to the “FW/DC 5V” port.
NOTE: All the ports support hot-plug.
3.3 Application
The SW-4X1SL18G is ideal for residential AV and corporate applications, such
as under the conference room table. From here, you can run up to four HDMI
cables to different points on the table, and then connect your devices (e.g.
laptops, tablets, and phones). The switcher handles user signal switching and
distribution. You can even connect secondary audio-video inputs, such as Blu-
Ray devices, computers, and cable boxes.

4. Panel Control
4.1 Input source switching
The “Auto Source” button on the front panel can be used to select input source and
switch mode.
4.1.1 Manual switching mode
Press the “Auto Source” button to switch among inputs 1~4, the corresponding
indicator will illuminate green for easy recognition.
4.1.2 Auto-switching mode
Press and hold the button “Auto Source” for 3 seconds or more to switch between
manual mode and auto mode. (Default: Manual switch.). Once enter auto-switching
mode, the “MODE” LED will light up.
The auto-switching mode abides by the following principles:
New input
Once a new input signal is connected, the SW-4X1SL18G will switch to the
new signal automatically.
Power Rebooting
The SW-4X1SL18G supports “power off” memory function. If the last
selected signal is still available, the switcher will output said signal. If not, the
switcher will detect all the input signals with priority from “IN 1” to “IN 4”
ports. When the first signal is detected, it will transfer to the output.
Signal removing
Once the current input signal is removed, the SW-4X1SL18G will detect all
input signals with priority directed towards the succeeding input port. It will
transfer the first available input source to the output device.
For example, the selected input signal is “IN 2”. If you disconnect the current
input source, SW-4X1SL18G will detect all input signals per the following
order: “IN 3”, “IN 4”, “IN 1”. Then the first available source will be switched as
the input.

6. RS232 Control
The SW-4X1SL18G provides an RS232 port for serial port control. Connect the
switcher to the control device (e.g. PC) with an RS232 cable and set the parameters in
the right manner. The control device can control the switcher via designed software.
6.1 Installation/uninstallation of RS232 Control Software
Installation: Copy the control software file to the computer connected with this
switcher.
Uninstallation: Delete all the control software files in corresponding file path.
6.2 Basic Settings
Connect this switcher with an input device and an output device. Then connect it with a
computer, which is installed with the RS232 control software. Double-click the software
icon to run this software.
Here we take the software CommWatch.exe as example. The icon is shown below:
The interface of the control software is shown below:
Please set the parameters of COM number, bound rate, data bit, stop bit and the parity
bit correctly. Only then will you be able to send command in the Command Sending
Area.
Baud rate: 9600 Data bit: 8 Stop bit: 1 Parity bit: none
