3. System Connection
3.1 Usage Precautions
1) System should be installed in a clean environment and has a prop temperature and
humidity.
2) All of the power switches, plugs, sockets and power cords should be insulated and
safety.
3) All devices should be connected before power on.
3.2 System Diagram
3.3 Connection Procedure
Step1. Connect HDMI source devices (e.g. Blue-ray DVD) to HDMI input ports of SC51T
with HDMI cable. Connect VGA source device (e.g. PC) to VGA input ports of
SC51T with VGA cable.
Step2. Connect the corresponding audio source to the corresponding AUDIO INPUT
port of SC51T with audio cable one to one. The audio of HDMI can be embedded
or external by sending right command.
Step3. Connect HDMI display device to HDMI output port of SC51T with HDMI cable.
Step4. Connect TPHD402PR to HDBaseT output port of SC51T with twisted pair.
Step5. Connect speaker, headphone or PTN amplifier to AUDIO OUTPUT port of
SC51T.
Step6. Connect control device (e.g. PC) to RS232 port of SC51T or TPHD402PR
(bi-directional RS232 control, either is available).
Step7. Both SC51T and TPHD402PR have IR IN and OUT. When one model is used for
PTN Electronics Limited
5
www.PTN-electronics.com
Compact Scaler Switcher (with PoC)
IR signal receiver, the IR signal must be sent out by the other model.
For example: When “IR IN” of SC51T connects with an IR receiver, the IR
transmitter must connect to IR OUT of TPHD402PR.
The IR signal can be transmitted bi-directionally between SC51T and
TPHD402PR.
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 (TPHD402PR is able to get
power from SC51T).
3.4 Connection of Microphone
SC51T provides with one 3-level microphone input, to accommodate different
microphone input modes, including 48V phantom power mode, MIC mode & LINE mode.
 48V phantom power input
When switch 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 condenser microphone.
Connection is: “+” connects to positive, “-” connects to negative and “
” to ground.
 MIC input
When switch to “MIC” (It has a low frequency characteristics, and wide frequency
response in this mode), the microphone input is used for connecting with dynamic
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 “
connects to ground.
”
 LINE input
When switch to “LINE” (It has a low frequency characteristics, and wide frequency
response in this mode), the microphone input is used for connecting with line audio or
wireless microphone output. There are two different connections:
 Unbalanced connection:
“+” and “
” connect to ground, and “-” connects to signal.
“-” and “
” connect to ground, and “+” connects to signal.
b) Balanced connection: “+” connects to positive, “-” connects to negative and “
connects to ground.

3.5 Application
SC51T 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 Buttons
The buttons can be used for output resolution adjusting, switching operations, software
updating, volume adjusting and operations in menus.
4.1.1 Resolution Adjusting
Supports auto-adjusting and manual-adjusting. Press and hold on RESO/AUTO button
for 3 seconds or more to enter in auto-adjusting/manual-adjusting mode.
Notice: In auto-adjusting mode, SC51T will choose the resolution of the display device
at the far-end as the preferred resolution.
If need to choose the resolution of local HDMI display device:
 Cut off the power of SC51T and break the connection between SC51T and
TPHD402PR.
 Turn on the power of SC51T.
 Gets the resolution of local HDMI output device.
 Connect TPHD402PR to SC51T.
4.1.2 Switching Operations
Supports auto-switching and manual-switching. Press and hold on SOURCE/AUTO
button for 3 seconds or more to enter in auto-switching/manual-switching mode.
The display result is showed as below:

Compact Scaler Switcher (with PoC)
Auto-switching function
The auto-switching mode follows the listed principles:
 New input principle
Once detecting a new input signal, SC51T would switch to this new signal
automatically.
 Power rebooting principle
SC51T offers the function to remember the signal last displayed when rebooting.
Once rebooting, SC51T will automatically enter in auto-switching mode, and then
detect all inputs and memorize their connection status for future rebooting using.
And if the signal last displayed is still available, then it will choose the signal to output.
If not, there will be no signal on outputs.
 Signal removing principle
Once removing the current display signal, SC51T will detect all input signals with
priority from INPUT 1 to INPUT 5. It will transfer the signal firstly detected to be
available to outputs.
Notice: Auto-switching function works only when input with new signal, remove a signal
or power rebooting.
Operation Examples:
 Connect the INPUT 2, INPUT 4, and INPUT 5 ports to the source devices, select
INPUT 4 to outputs.
 Press and hold on the front key SOURCE/AUTO for 3 seconds or more to enter in
auto-switching mode.
 No signal removing or new input, SC51T 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, SC51T 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 SC51T, then reboot. As SC51T is in auto-switching mode, then it
will choose INPUT 2 to output.

CEC: Control HDMI source devices by IR remote of SC51T
4.4 Operations of RS232 Control
As RS232 can be transmitted bi-directionally between SC51T and TPHD402PR, so it is
able to control a third party RS232 device from local or control SC51T from remote.
When to control a third party RS232 device, the baud rate of this device should be 2400,
4800, 9600, 19200, 38400, 57600 or 115200.
4.4.1 Installation/uninstallation of RS232 Control Software
 Installation Copy the control software file to the computer connected with SC51T.
 Uninstallation Delete all the control software files in corresponding file path.
4.4.2 Basic Settings
First to connect SC51T with all input devices and output devices needed, then to

7. Troubleshooting & Maintenance
1) When output image is with snowflake, such as the projector output with snowflake.
Generally this is not a unit faulty,
 Caused by a bad quality of cable. Please try another high quality cable.
 The video cables are loose, please connect again.
2) When it is not able to manage EDID, maybe the HDMI cable is broken or loose.
3) When user cannot control the switcher by computer through its COM port, please
check the COM port number in the software and make sure the COM port is in
good condition.
4) If the POWER indicator doesn’t work or no respond to any operation, please make
sure the power cord connection is good.
5) When switching , there is no output image:
 Check with oscilloscope or multimeter if there is any signal at the input/output
end. If there is no signal input/output, it may be the input/output connection
cord broken or the connectors loosen. Please change for another cable or
connect again.
 If it is still the same after the above checking, maybe there is something wrong
in the switcher. Please send it to the dealer for fixing.
6) If the static becomes stronger when connecting the video/audio connectors, it
probably due to the incorrect grounding, please correct it otherwise it would
damage the switcher.
7) If it is not able to control the scaler switcher from front panel buttons, but able
through RS232 commands, maybe the front panel buttons are locked. Please send
command 50605% to unlock.
8) If the scaler switcher cannot be controlled by the buttons on the front panel, RS232
port or IR remote, the switcher may have broken. Please send it to the dealer for
repairing.
