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
safe.

3) All devices should be connected before power on.

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 devices (e.g. PC) to VGA input ports of
SC51T with VGA cable.

Step2. Connect audio sources to corresponding AUDIO INPUT ports on SC51T 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 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 end is available).

Step7. Both SC51T and TPHD402PR 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 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 with PoC function).

Note: SC51T supports unidirectional PoC, i.e., If the power adapter is connecting with
SC51T, TPHD402PR can get power from SC51T; but when the power adapter is
connecting with TPHD402PR, SC51T can get power from TPHD402PR.

3.4 Connection of Microphone

SC51T 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

Compact Scaler Switcher (with PoC)

PTN Electronics Limited 7 www.PTN-electronics.com

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.
