1. Introduction
This is a high performance four input & two outputs switcher.
The output ports support Audio Return Channel (ARC) and HDMI Ethernet
Channel (HEC) according to HDMI v1.4 specification. The SWITCH-4X2 provides
a S/PDIF link from the sink to feed an AV receiver to get digital audio from the
sink decoder. The most typical application for this is a TV with built in Satellite
receiver that decodes digital audio and forwards the SPDIF signal through the
HDMI cable to the SWITCH-4X2 instead of running an additional SPDIF
connection wire.
Another HDMI 1.4 feature is the HEC that adds a connection to the HDMI
link that is capable of carrying the same data as a full duplex, 100Mbps
Ethernet connection. Connection a Fast speed HDMI cable with Ethernet allows
convenient integration of Digital Televisions (DTVs) into the end user’s home
network system. Simply connect the network cable to the SWITCH-4X2 and make
your TV part of the IP network through the HDMI cable.
2. Applications
•Simultaneously display one HDMI source on 2 TVs
•Professional audio display
•Showroom display
•Education demo
•Commercial usage
3. Package Contents
•4 x 2 HDMI Switcher with HEAC
•5V/2.6A DC power supply adaptor

7. Operation Controls and Functions
The following sections describe the hardware components of the unit.
7.1 Front Panel
1
. IR Remote Control Sensor.
2
. Audio/3D content indicator: The system will automatically detect
incoming audio/video signal and the Green LEDs will illuminate
accordingly.
3
. Input selection: Press input button to select input source, the Blue LED will
illuminate accordingly.
4
. EDID selection: This EDID control button is determining if the SWITCH-4X2 is
forwarding the EDID from the display attached to output 1 or use the
preprogrammed EDID. The STD or TV Green LED will illuminate
accordingly. When press EDID button longer then 3 seconds, the RED LED
will illuminate which means the EDID has been locked to STD or TV EDID as
selected previously.
5
. Power LED Indicator: The LED will illuminate when the power is
connected.

7.2 Rear Panel
1
. RS-232: This slot is for RS-232 control signal and for service only.
2
. The Audio return and Ehternet connectors are part of the new HDMI 1.4
features. Both outputs have their own individual audio return and Ethernet
channel. To make these outputs work the TV connected to the HDMI OUT 1
and 2 have to support HDMI 1.4 and the cable must be of the Fast Speed
with Ethernet type.
Typically the digital audio outputs are used to feed an AV receiver that is
located at the SWITCH-4X2 location receiving the decoded audio signal
from the TV through the HDMI cable. No additional audio return wire is
necessary.
The Ethernet port serves a similar purpose, you may connect your IP
connection to the SWITCH-4X2 and supply a network connection through
the HDMI cable to your TVs.
One HDMI cable can carry HD Video to your TV, receive the decoded
audio and pass IP network signals in both directions !
3
. HDMI input 1~4: Connect these to HDMI or DVI source equipment such
as DVD player or set-top-box.
4
. Power: Plug the DC 5V power supply into the sSWITCH-4X2 and
connect the adaptor to AC wall outlet.
