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.
3.2. System Diagram

Scaler Switcher with Digital Amplifier
3.3. Connection Procedures
Step1. Connect source devices (e.g. PC, DVD) to video input ports with corresponding
cables. For example, connect VGA INPUTS ports and the VGA ports of source
devices via VGA cable.
Step2. Connect the corresponding audio source to the corresponding AUDIO INPUT
port of SC121D-TN with audio cable separately. C-VIDEO1 shares the same
audio input port with S-VIDEO3; YPbPr shares the same audio input port with
C-VIDEO4, you can select either side as audio input port.
Step3. Connect a microphone to the MIC input port; plug an audio source device or a
wireless microphone to the LINE port.
Step4. Connect a control device (e.g. a PC) to the TCP/IP ports or RS232 sockets of
SC121D-TN. Send commands to control SC121D-TN via control software.
Step5. Connect the HDMI HDBT port of SC121D-TN with TPHD402PR to extend the
signal.
Step6. Connect display devices to video output ports; connect earphones/amplifiers to
audio output ports. (Abiding by the color instruction on output sockets)
Step7. Connect the output ports of amplifiers to stereo equipments.

Step8. Plug the power cable of SC121D-TN to an AC100V~240V power supply,
TPHD402PR is able to get energized with PoC solution.
3.4. PoC Solution
HDBT port supports PoC, which allows SC121D-TN and TPHD402PR share the same
power supply and eliminates the need for extra power supply at the remote nodes.
Connect SC121D-TN with TPHD402PR via a CAT5e/6 cable, then plug the power cable
of SC121D-TN to an AC100V~240V power supply, TPHD402PR can be energized
synchronously with PoC solution, see the picture below:
Note: To activate PoC solution, all related parts (including the devices to share the
same power supply and connecting cable) should support PoC.
