4.3 Connection Procedure
a) Connect HDMI source devices (e.g. Blue-ray DVD) to HDMI input ports of the
500435 with HDMI cables. Connect VGA source devices (e.g. PC) to VGA input
ports of the 500435 with VGA cables.
b) Connect audio sources to corresponding Audio Input ports on the 500435 with
audio cable. The audio of HDMI can be selected from the embedded audio or from
the external audio.
c) Connect an HDMI display device to the HDMI output port of the 500435 with HDMI
cable.
d) Connect HDMI Extender PoC/PoE Receiver to the HDBaseT output port of the
500435 with a twisted pair Cat5e/6 cable.
e) Connect speakers, headphones or an amplifier to the Audio Output port of the
500435.
f) Connect control device (e.g. PC) to the RS232 port of the 500435; or to the HDMI
Extender PoC/PoE Receiver (with bidirectional RS232 control).
g) Both the 500435 and the HDMI Extender PoC/PoE Receiver have IR sensors and
emitters. When one end is connected with IR sensor, the other end should be
connected with an IR emitter.
•
For example: When an “IR Sensor” of the 500435 connects to an IR Sensor,
the IR Emitter must be connected to IR Emitter port of HDMI Extender
PoC/PoE Receiver.
•
The IR signal can be transmitted in both directions simultaneously between the
500435 and the HDMI Extender PoC/PoE Receiver.
h) Select MIC level and connect the right microphone to Microphone input port. MIC
audio will be transmitted to Audio Output port and mixed with the audio source.
i) Connect 12V DC power to the power port. The HDMI Extender PoC/PoE Receiver
will get power from the 500435 via PoC/PoE function.
4.4 Connection of Microphone
The 500435 provides with 3-level microphone input port, to accommodate different
microphone input modes, including 48V phantom power mode, MIC mode & LINE mode.
48V phantom power input:
The 48V phantom power input has a good frequency characteristic, high input
impedance and high sensitivity.
When switching to “48V”, the MIC input will provide a 48V phantom power. This is only
used for condenser microphones.

5x1 HDMI / HDBT Multimedia Presentation Switch Installation Guide

Connect the microphone as follows: “+” connects to positive, “-” connects to negative
and “ ” to ground.
MIC input
MIC input has a low frequency characteristic, and a wide frequency response.
When switched to “MIC”, the microphone input is used for connecting with a dynamic
microphone. There are two different connection methods:
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.
LINE input
LINE input has a low frequency characteristic, and a wide frequency response.
When switched to “LINE”, the microphone input is used for connecting with line audio or
wireless microphone output. There are two different connection methods:

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.
4.5 Application
The 500435 product can be used in multiple applications, such as computer realm,
monitoring, conference room, big screen display, television education, command &
control center, smart home, etc.

5. Operations
5.1 Operations of Front Panel Buttons
Front panel buttons can be used for adjusting output resolution, switching operations,
software updating, volume adjusting and other operations in the menus.
5.1.1 Adjusting Resolution
There are two modes available: auto-adjust and manual-adjust. Press and hold the
Resolution/Auto button for 7 seconds or more to switch between auto-adjust and
manual-adjust modes.
Note:
1) In auto-adjust mode, the 500435 will choose the resolution of the display device at
the far-end as the preferred resolution. If you need to choose the resolution of a
local HDMI display device, follow the steps below:
•Turn off the power of the 500435 and disconnect the HDMI Extender PoC/PoE
Receiver.
•Turn on the power of the 500435.
•The 500435 gets the resolution of the local HDMI output device.
•Connect the HDMI Extender PoC/PoE Receiver to the 500435.
2) In auto-switch mode, the front panel button control is not active, but it is possible to
switch modes from the IR or RS232 controls.
5.1.2 Switching Operations
Video signals support auto-switching and manual-switching. Press and hold
Source/Auto button for 7 seconds or more to enter the auto-switching or the
manual-switching mode.
The display result is showed as below:
The display result will be showed for 2 seconds.

1280 X 720
IN: HDMI1 AUTO
1280 X 720

5x1 HDMI / HDBT Multimedia Presentation Switch Installation Guide

Auto-switching function:
The auto-switching function works as follows:
New input
When a new input signal is detected, the 500435 will switch to this new signal
automatically.
Signal loss
When the current display signal is lost, the 500435 will detect other input signals with
priority from INPUT 1 to INPUT 5. It will detect the first signal and switch it to the
output devices.
Power reboot
The 500435 offers the function to remember the last displayed signal when
rebooting. Once rebooted, the 500435 will automatically enter auto-switching mode,
and then detect all inputs and memorize their connection status for future rebooting.
If the last displayed signal is still available, the 500435 will output that signal. If not,
there will be no signal on output devices.
Note: Auto-switching function works only when a new signal is detected, when a
signal lost or when rebooting the unit. When any VGA input port is set to AV
or YPbPr, the system will always stay in Manual-switching mode.
Operation Examples:
•Connect Input 2, Input 4, and Input 5 ports with source devices, select Input 4.
•Press and hold Source/Auto button for 7 seconds or more to enter the
auto-switching mode.
•The 500435 is now in auto-switching mode. If there is no signal loss or no new input,
the Output will still be connected to Input 4.
•Connect Input 3 with an active source device; the outputs will automatically connect
to Input 3.
•Remove the signal of Input 3; the 500435 will detect from Input 1 to Input 5, and will
automatically switch to Input 2.
•Turn off the power of the 500435. As the 500435 is in auto-switching mode, it will
choose Input 2 to output when power is restored.
5.1.3 Adjusting the Volume
When not in OSD menu, press VOL – to decrease line volume, VOL + to increase line
volume; press MIC – to decrease MIC volume, MIC + to increase MIC volume.
