3.3 Connection Procedure
Step1. Connect HDMI source devices (e.g. Blue-ray DVD) to HDMI input ports of
Compact Scaler Switcher with HDMI cable. Connect VGA source devices (e.g.
PC) to VGA input ports of Compact Scaler Switcher with VGA cable.
Step2. Connect audio sources to corresponding AUDIO INPUT ports on Compact
Scaler Switcher 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 Compact Scaler Switcher
with HDMI cable.
Step4. Connect HDMI Twisted Pair PoC Receiver to HDBaseT output port of Compact
Scaler Switcher with twisted pair.
Step5. Connect speaker, headphone or amplifier to AUDIO OUTPUT port of Compact
Scaler Switcher.
Step6. Connect control device (e.g. PC) to RS232 port of Compact Scaler Switcher or
HDMI Twisted Pair PoC Receiver (bi-directional RS232 control, either end is
available).
Step7. Both Compact Scaler Switcher and HDMI Twisted Pair PoC Receiver 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 Compact Scaler Switcher connects with an IR
receiver, the IR transmitter must connect to IR OUT of HDMI Twisted Pair PoC
Receiver.
The IR signal can be transmitted bi-directionally between Compact Scaler
Switcher and HDMI Twisted Pair PoC Receiver.
Step8. Select MIC level and connect right microphone to MIC input port. MIC audio will
be transmitted to AUDIO OUTPUT port and mixed with source audio.
Step9. Connect DC12V power adaptor to the power port (HDMI Twisted Pair PoC
Receiver is able to get power from Compact Scaler Switcher with PoC function).
Note: Compact Scaler Switcher supports unidirectional PoC, i.e., If the power adapter
is connecting with Compact Scaler Switcher, HDMI Twisted Pair PoC Receiver can get
power from Compact Scaler Switcher; but when the power adapter is connecting with
HDMI Twisted Pair PoC Receiver, Compact Scaler Switcher can get power from HDMI
Twisted Pair PoC Receiver.
3.4 Connection of Microphone
Compact Scaler Switcher 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
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.
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 “ ”

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:
1. In auto-adjusting mode, Compact Scaler Switcher 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 Compact Scaler Switcher and disconnect Compact Scaler
Switcher and HDMI Twisted Pair PoC Receiver.
Turn on the power of Compact Scaler Switcher.
Gets the resolution of local HDMI output device.
Connect HDMI Twisted Pair PoC Receiver to Compact Scaler Switcher.
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, Compact Scaler Switcher would switch to this
new signal automatically.
Power rebooting principle
Compact Scaler Switcher offers the function to remember the last displayed signal
when rebooting. Once rebooted, Compact Scaler Switcher 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, Compact Scaler Switcher will output the
signal. If not, there will be no signal on output devices.
Signal removing principle
Once removing the current display signal, Compact Scaler Switcher 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 VGA port 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, Compact Scaler Switcher 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, Compact Scaler Switcher 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 Compact Scaler Switcher, then reboot. As Compact Scaler
Switcher is in auto-switching mode, it will choose INPUT 2 to output.
4.1.3 Volume Adjusting
