3. System Connection

3.1 Usage Precaution s

1) System should be installed in a clean environmen t and has a prop temper at ur e and

humidity.

2) All of the power switches, plugs, sockets and power cords should be insulated and
safe.

3) All devices should be connected before power on.

3.2 System Diagram

Compact Scaler Switcher

PTN Electronics Limited 5 www.PTN-electronics.com

3.3 Connection Procedure

Step1. Connect HDMI source devices (e.g. Blue-ray DVD) to HDMI input ports of

SC51D with HDMI cable. Connect VGA source devices (e.g. PC) to VGA input
ports of SC51D with VGA cable.

Step2. Connect the corresponding audio source to the corresponding AUDIO INPUT

port of SC51D with audio cab l e accordingly. The audio of HDMI can be set as
embedded or external by sending right commands.

Step3. Connect a HDMI display device to HDMI output port of SC51D with HDMI cable.
Step4. Connect speakers, headphones or PTN amplifiers to AUDIO OUTPUT port of

SC51D.

Step5. Connect control device (e.g. PC) to the RS232 port of SC51D.
Step6. Select MIC level and connect right microphone to the MIC input port. MIC audio

will be transmitted to AUDIO OUTPUT port and mixed with source audio.

Step7. Connect DC12V power adaptor to the power port.

3.4 Connection of Microphone

SC51D provides 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 offer a 48V phantom power. This is only
used for condenser microphone.

Connect the microphone this way: “+” connects to positive, “-” connects to negative and
“ ” to ground.

Compact Scaler Switcher

PTN Electronics Limited 6 www.PTN-electronics.com

 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 connect ing w ith line audio or
wireless microphone output. There are two different connections:

Compact Scaler Switcher

PTN Electronics Limited 7 www.PTN-electronics.com

1) 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

SC51D has a good application in various occasion s, suc h as computer realm,
monitoring, conferen ce room, big screen displaying, television education, command &
control center and smart house etc.

4. System Operations

4.1 Operations of Buttons

The buttons can be used for output resolution adjusti ng, sw itchin g operations, software
updating, volume adjusting and operatio ns in menu s.

4.1.1 Resolution Adjusting

Support auto-adjusting and m anual-adjusting. Press and hold on RESO/AUTO button
for 7 seconds or more to enter in auto-adjusting/manual-adjusting mode.

Notice:

1. In auto-adjusting mode , SC51D will choose the resoluti on of the display dev ice a s th e

preferred resolution.

Compact Scaler Switcher

PTN Electronics Limited 8 www.PTN-electronics.com

2. In auto-switching mode, front panel button control is not available, but IR and RS232

control is able to switch modes.

4.1.2 Switching Operations

Support auto-switching and m anual-switching. Press and hold on SOURCE/AUTO
button for 7 seconds or more to enter in auto-switching/manual-switching mode.

The display result is show ed as below :

The display result will be showed for 2 seconds.

The auto-switching mode follows the listed principles:
 New input principle

Once detecting a new input signal, SC51D would switch to this new signal
automatically.

 Power rebooting principle

SC51D offers the function to remember the signal last displayed when rebooting.
Once rebooting, SC51D 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 SC51D will output the signal. If
not, there will be no signal on output s.

 Signal removing principle

Once removing the current display signal, SC51D will d ete ct all input signals with
priority (from INPUT 1 to INPUT 5). It will output the signal firstly detected to be
available.

Notice: Auto-switching function works only when there is new input signal, or when
users remove 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 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 7 seconds or more to enter in

auto-switching mode.

 With n o signal removing or new input, SC51D 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, SC51D 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 SC51D, then reboot. As SC51D is in auto-switching mode, then

it will choose INPUT 2 to output.

4.1.3 Software Updating

Software updating means to update the inside program of this scaler switcher.
SC51D supports software updating via USB flash disk. The Operation is:

1) Copy the file “MERGE_51D.bin” to the root dire ctory of a U SB flash di sk. (M ake sure
the file is copied to the root directory for normal use. The “MERGE_51D.bin” file is
provided/authorized by PTN engineering department or from our website:

http://www.PTN-electronics.com)

2) Plug the USB flash disk to the SC51D USB port on its front panel.

3) Press the button “MENU” for 7 seconds or more to update the software

automatically.
Or press this button for 1 second to open the OSD menu “Option”  Select

“Software Update” to enter in update procedure.
Or send command 50698% to update software.

4.1.4 Volume Adjusting
