Auto-Switching function
The switch has auto-switching and manual-switching modes. When in auto-switching mode, it will follow
the following principles:
New input: Once a new input signal is detected, the switch will switch to this new signal automatically.
Power reboot: The switch offers the function to remember the signal last used before power off. Once
rebooted, it will automatically enter auto-switching mode, and then detect all inputs and memorise their
connection status for future reboots. If the last used input signal is still available, then it will choose that
signal. If not, it will detect all input signals with priority on HDMI1->HDMI2->HDMI3->DP->VGA
(YPbPr/CVBS).
Removed Signal: Once the current signal is removed, the switch will detect all input signals with priority
on HDMI1->HDMI2->HDMI3->DP->VGA (YPbPr/CVBS). It will transfer the first signal detected to the
output.
Notice: The Auto-switching function works only when there is a new input signal or if an input signal is
removed.
VGA/YPbPr/CVBS input
The VGA input port is a multiple format port. It supports VGA/YPbPr/CVBS input signals. The switch will
auto detect the input signal type and format. You can use the converter cable for YPbPr or CVBS signal
inputs.

User Manual English
Connection of Microphone
The switch provides one 2-level microphone input to accommodate different microphone input modes,
including 48V phantom power mode and MIC mode.
When switched to “ON” (It has a good frequency characteristics, high input impedance and high
sensitivity in this mode), the MIC input will provide 48V phantom power. This should only be used for
48V condenser microphones.
1) Unbalanced connection:
“+” and “ ” connect to ground, and “-” connects to signal.
“-” and “ ” connect to ground, and “+” connects to signal.
2) Balanced Connections: “+” connects to positive, “-” connects to negative and “ ” to ground.
When switched to “OFF” (It has low frequency characteristics and wide frequency response in this
mode), the microphone input is used for connecting dynamic and condenser microphones. There are two
different connections:
1) Unbalanced connection:
“+” and “ ” connect to ground, and “-” connects to signal.
“-” and “ ” connect to ground, and “+” connects to signal.

User Manual English
2) Balanced connection: “+” connects to positive, “-” connects to negative and “ ”connects to ground.
Operations of RS-232 Control
As RS-232 can be transmitted bi-directionally between the switch and the HDBaseT receiver, it is able to
control a third-party RS-232 device locally or control the switch bi-directionally.
1) Control the Switch or 3rd Party Device from the local side
2) Control the Switch or 3rd Party Device from remote Receiver

User Manual English
3) RS-232 Control
Please connect the switch with a computer that has been installed with the RS-232 control software. The
interface of the control software is shown as below:

Web GUI Control
The switch can be controlled via a Web browser, which contains General, Setup and Network Settings.
After the active Ethernet link with a RJ45 cable is connected, the IP address is entered in the Web
browser. If the IP address is unknown, there are two methods to obtain the IP address.
1. Obtain the IP address and port number via the information from the MENU-> Network OSD using the
remote control.
2. Obtain the IP address and port number via the RS-232 Control software.
For example, the obtained IP address is 192.168.1.100. Input http://192.168. 1.100 in the address bar of
the web browser.
