3.3 Connection Procedure
Step1. Connect HDMI source devices (e.g. Blue-ray DVD) to HDMI input ports of
VL120000 with HDMI cable. Connect VGA source devices (e.g. PC) to VGA input
ports of VL120000 with VGA cable.
Step2. Connect audio sources to corresponding AUDIO INPUT ports on VL120000
with audio cable. The audio of HDMI can be embedded or external by sending the
right command.
Step3. Connect a HDMI display device to HDMI output port of VL120000 with HDMI
cable.
Step4. Connect VL120001R to HDBaseT output port of VL120000 with twisted pair.
Step5.Connect speaker,headphone or VivoLink amplifier to AUDIO OUTPUT port of
VL120000
Step6. Connect control device (e.g. PC) to RS232 port of VL120000 or VL120001R
(bi-directional RS232 control, either end is available).
Step7. Both VL120000 and VL120001R have IR IN and OUT. When one model is
connected with IR receiver, the other model should connect with an IR transmitter.
For example: When “IR IN” of VL120000 connects with an IR receiver, the IR
transmitter must connect to IR OUT of VL120001R.
The IR signal can be transmitted bi-directionally between VL120000 and
VL120001R.
Step8.Select MIC level and connect right microphone to MIC input port. MIC audio will
be transmitted toAUDIO OUTPUT port and mixed with source audio.
Step9. Connect DC12V power adaptor to the power port (VL120001R is able to get
power from VL120000 with PoC function).
Note: VL120000 supports unidirectional PoC, i.e., If the power adapter is connecting
with VL120000, VL120001R can get power from VL120000; but when the power
adapter is connecting with VL120001R, VL120000 cannot get power from VL120001R.
3.4 Connection of Microphone
VL120000 provides with one 3-level microphone input port, to accommodate different
microphone input modes, including 48V phantom power mode, MIC mode & LINE mode.
48V phantom power input
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 microphone.
Connect the microphone in this way: “+” connects to positive, “-” connects to negative
11

Compact Scaler Switcher (with PoC)
and “ ” to ground.
MIC input
MIC input has a low frequency characteristics, and wide frequency response.
When switch to “MIC”, the microphone input is used for connecting with 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 characteristics, and wide frequency response.
12

Compact Scaler Switcher (with PoC)
When switch 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.
3.5 Application
VL120000 has a good application in various occasions, such as computer realm,
monitoring, conference room, big screen displaying, television education, command &
control center and smart home etc.
4. System Operations
4.1 Operations of Front Panel Buttons
Front panel buttons can be used for output resolution adjusting, switching operations,
software updating, volume adjusting and other operations in menus.
4.1.1 Resolution Adjusting
Resolution supports auto-adjusting and manual-adjusting. Press and hold for
RESO/AUTO button for 7 seconds or more to switch between auto-adjusting/ manual-
adjusting mode.
Note:
13

Compact Scaler Switcher (with PoC)
1. In auto-adjusting mode, VL120000 will choose the resolution of the display device at
the far-end as the preferred resolution.
If you need to choose the resolution of local HDMI display device:
Cut off the power of VL120000 and disconnect VL120000 and VL120001R.
Turn on the power of VL120000.
Gets the resolution of local HDMI output device.
Connect VL120001R to VL120000.
2. In auto-switching mode, front panel button control is not available, but IR and RS232
control are able to switch modes.
4.1.2 Switching Operations
Video signals support auto-switching and manual-switching. Press and hold for
SOURCE/AUTO button for 7 seconds or more to enter in auto-switching/ manual-
switching mode.
The display result is showed as below:
The display result will be showed for 2 seconds.
The auto-switching mode abides by the following principles:
New input principle
Once detecting a new input signal, VL120000 would switch to this new signal
automatically.
Power rebooting principle
VL120000 offers the function to remember the last displayed signal when rebooting.
Once rebooted, VL120000 will automatically enter auto-switching mode, and then
detect all inputs and memorize their connection status for future rebooting using.
If the last displayed signal is still available, VL120000 will output the signal. If not,
there will be no signal on output devices.
Signal removing principle
Once removing the current display signal, VL120000 will detect all input signals with
priority from INPUT 1 to INPUT 5. It will transfer the signal firstly detected to be
available to output devices.
Notice: Auto-switching function works only when inputting new signal, removing a
signal or power rebooting. With any VGAport set to AV or YPbPr, the system will be not

able to enter in Auto-switching mode.
Operation Examples:
Connect INPUT 2, INPUT 4, and INPUT 5 ports with source devices, select INPUT
4 to outputs.
Press and hold for the front key SOURCE/AUTO for 7 seconds or more to enter in
auto-switching mode.
No signal removing or new input, VL120000 just works in auto-switching mode,
and take no action (Output from INPUT 4)
Connect INPUT 3 with a source device, and then it will choose INPUT 3 to output.
Remove the signal of INPUT 3, VL120000 will detect from INPUT 1 to INPUT 5.
And when it detects that input 2 is available, it will choose INPUT 2 to output.
Cut off the power of VL120000, then reboot. As VL120000 is in auto-switching
mode, it will choose INPUT 2 to output.
