HDMI/HEAC equipped TVs or displays will pass the Ethernet andAudio signals via HDMI v1.4 cable back to the HDMI Output port,
the splitter will separate the Ethernet and audio, and will outputaudio from the ARC and bi-directional data streams through theEthernet ports. If the display has a built-in tuner or an attached
DVD player, audio content can be sent “upstream” from the TV
back to the audio system to be output in multi-channel audio.
The HDMI Switcher can use the HDMI Ethernet Channel (HEC) toconsolidate video, audio and data streams into a single HDMI
cable connection to an Ethernet Hub/modem in order to accessthe internet and also incorporates a dedicated data channel
into the HDMI link, enabling high-speed, bi-directional networkingat up to 100 Mb to control and search from the sink (please see
Section 6 for connection diagram). The HDMI output number iscorrespondingto ARC and Ethernet output number.
Note 1: Be sure to connect devices with a suitable HDMI cable
designed to support the Ethernet Channel functionality, either thestandard HDMI cable with Ethernet or High Speed HDMI cable withEthernet.

3 HDMI INPUT 1~4Connect to HDMI or DVI sources equipment such as DVD player orset-top-box for input video and audio sending.
Note A: This system was tested with 24 AWG cables. If using cablesof another specification, the performance of this system may vary.
