Note:
Pictures shown in this manual are for reference only, different model and
specifications are subject to real product.
TCP/IP port and HDBT port are selectable. When there is a TCP/IP port, the
switcher may be named as Scaler Switcher with Digital Amplifier-N. When there is
a HDBT port, the switcher may be named as Scaler Switcher with Digital Amplifier-
T.
For example, the name “Scaler Switcher with Digital Amplifier-TN” suggests that
the switcher has both the two port. While “Scaler Switcher with Digital Amplifier”
suggests that the switcher has neither a TCP/IP port nor a HDBT port.
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 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 Scaler Switcher with Digital Amplifier-TN with audio cable separately. C-
VIDEO1 shares the same audio input port with S-VIDEO3; Pr-Pb-Y 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
Scaler Switcher with Digital Amplifier-TN. Send commands to control Scaler
Switcher with Digital Amplifier-TN via control software.
Step5. Connect the HDMI HDBT port of Scaler Switcher with Digital Amplifier-TN with
HDMI twisted pair Receiver with PoC 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 the switcher to an AC100V~240V power supply, HDMI
twisted pair Receiver with PoC is able to get energized with PoC solution.
3.4. PoC Solution
HDBT port supports PoC, which allows Scaler Switcher with Digital Amplifier-TN and
HDMI twisted pair Receiver with PoC share the same power supply and eliminates the
need for extra power supply at the remote nodes.
Connect Scaler Switcher with Digital Amplifier-TN with HDMI twisted pair Receiver with
PoC via a CAT5e/6 cable, then plug the power cable of the switcher to an AC100V~240V
power supply, HDMI twisted pair Receiver with PoC 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.
