3.3 Connection Procedure
Step1. Connect HDMI source devices (e.g. Blue-ray DVD) to HDMI input ports of
SCA51T with HDMI cable. Connect VGAsource devices (e.g. PC) to VGA input
ports of SCA51T with VGA cable.
Step2. Connect audio sources to corresponding AUDIO INPUT ports on SCA51T
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 SCA51T with HDMI
cable.
Step4. Connect TP402PR to HDBaseT output port of SCA51T with twisted pair.
Step5. Connect speaker, headphone or amplifier to AUDIO OUTPUT port of
SCA51T.
Step6. Connect control device (e.g. PC) to RS232 port of SCA51T or TP402PR
(bi-directional RS232 control, either end is available).
Step7. Both SCA51T and TP402PR 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 SCA51T connects with an IR receiver, the IR
transmitter must connect to IR OUT of TP402PR.
The IR signal can be transmitted bi-directionally between SCA51T and
TP402PR.
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 (TP402PR is able to get
power from SCA51T with PoC function).
Note: SCA51T supports unidirectional PoC, i.e., If the power adapter is connecting with
SCA51T, TP402PR can get power from SCA51T; but when the power adapter is
connecting with TP402PR, SCA51T can not get power from TP402PR.
3.4 Connection of Microphone
SCA51T 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.

Compact Scaler Switcher (with PoC)
Altimium 9 www.altimium.com
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

Compact Scaler Switcher (with PoC)
Altimium 10 www.altimium.com
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 “ ”
connects to ground.
3.5 Application
SCA51T 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:
1. In auto-adjusting mode, SCA51T 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 SCA51T and disconnect SCA51T and TP402PR.
Turn on the power of SCA51T.
Gets the resolution of local HDMI output device.
Connect TP402PR to SCA51T.
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, SCA51T would switch to this new signal
automatically.
Power rebooting principle

Auto-switching function

Compact Scaler Switcher (with PoC)
Altimium 12 www.altimium.com
SCA51T offers the function to remember the last displayed signal when rebooting.
Once rebooted, SCA51T 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, SCA51T will output the signal. If not,
there will be no signal on output devices.
Signal removing principle
Once removing the current display signal, SCA51T 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, SCA51T 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, SCA51T 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 SCA51T, then reboot. As SCA51T is in auto-switching mode, it
will choose INPUT 2 to output.
4.1.3 Volume Adjusting
Not in OSD menu, press VOL –to decrease line volume, VOL + to increase.
Not in OSD menu, press MIC –to decrease MIC volume, MIC + to increase.
