5.5 Auto-Switching function
The switcher has auto-switching and manual-switching modes. When the user selects auto-switching mode,
it will follow the following principles:
5.5.1. New input principle
Once a new input signal is detected, the switcher will switch to this new signal automatically.
5.5.2. Power rebooting principle
The switcher 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 memorize 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).
5.5.3. Signal removing principle
Once the current signal is removed, the switcher 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: Auto-switching function works only when there is a new input signal or if an input signal is removed.
5.6 VGA/YPbPr/CVBS input
The VGA input port is a multiple format port. It supports VGA/YPbPr/CVBS input signal. The switcher will
auto detect the input signal type and format. The user can use the convert cable for YPbPr or CVBS signal
input.
5.7 Connection of Microphone
The switcher provides one 2-level microphone input to accommodate different microphone input modes,
including 48V phantom power mode, MIC mode and Line Mode.

P/N: S00302
5.7.1 48V mode
When switched to “48V” (It has a good frequency characteristic, high input impedance and high sensitivity
in this mode), the MIC input will provide a 48V phantom power. This is only 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.
5.7.2 MIC mode
When switched to “MIC” (It has a low frequency characteristic, and wide frequency response in this mode),
the microphone input is used for connecting dynamic microphones and electrets condenser microphone.
There are two different connections:
1) Unbalanced connection:
“+” and “ ” connect to ground, and “-” connects to signal.
“-” and “ ” connect to ground, and “+” connects to signal.
2) Balanced connection: “+” connects to positive, “-” connects to negative and

Stock Code 873117 en.rgble.com 400-1661-021
P/N: S00302
“ ”connects to ground.
5.7.3 Line mode
When switched to “LINE” (It has a low frequency characteristic, and wide frequency
response in this mode), the microphone input is used for connecting line audio or wireless
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.
2) Balanced connection: “+” connects to positive, “-” connects to negative and
“ ”connects to ground.
5.8 Operations of RS-232 Control
As RS-232 can be transmitted bi-directionally between the switcher and the HDBT receiver, it is able to
control a third-party RS-232 device locally or control the compact switcher bi-directionally.
1) Control the Switcher or 3rd Party Device from Local

2) Control the Switcher or 3rd Party Device from remote Receiver
3) RS-232 Controller
Please connect the switcher with input devices and output device needed, then connect it with a
computer that is installed with RS-232 control software (attention: the switcher RS-232 port settings
must same with the software settings, e.g.: baud rate, data bits, parity, stop bits). Double-click the
software (Hercules) icon to run this software on your computer. The interface of the control software is
showed as below:
