Operation The GHSW8242 offers easy and flexible source device selection from the front panel buttons, the supplied remote control, or through the RS-232 serial interface. Note: 1. When the GHSW8242 is powered on and there is no video input source connected, it automatically selects Port 1 as the active port (i.e., the Port 1 LED lights up). You may choose one of the methods outlined below to select a different port as your active port. 2.
Audio Return Channel (ARC) Audio Return Channel (ARC) allows an HDMI display that receives or plays content via air waves or Internet applications (such as a TV or STB connected to a satellite antenna) to send audio “upstream” to your HDMI audio / video receiver using the same HDMI cable. Initial Setup The GHSW8242 supports dual HDMI output for dual view, such as two HDTV or audio/video receiver (AVR) applications, as shown in the following diagram.
Enabling ARC With ARC enabled, the TV can act as the HDMI source and send audio “upstream” to the AVR or speakers connected to the GHSW8242. Press the ARC button on the front panel of the GHSW8242 to enable or disable ARC. Note: The HDMI output port 1 is also the ARC input port, depending on whether the ARC feature is enabled or disabled. See ARC Commands, page 18 for more information.
RS-232 Serial Interface RS-232 Serial Interface The GHSW8242’s built-in bi-directional RS-232 serial interface allows system control through a high-end controller, PC, and/or home automation / home theater software package.
