The Concept
Three audio sources are connected to the transmitter: a Blu-ray player on the HDMI input (embedded HDMI
audio); a Laptop on the analog audio input 1; and a Media player on the analog audio input 2. There are two
video sources as well: the Blu-ray player on the HDMI input (digital video with the embedded audio) and the
Laptop on the VGA input (analog video).
▪ If the video input source of the HDTV is the Blu-ray player, you can select from the following audio
sources:
– the original embedded HDMI audio from the Blu-ray player;
– the analog audio input 1 from the Laptop;
– the analog audio input 2 from the Media player.
▪ If the video input source of the HDTV is the Laptop, you can select from the following audio sources:
– the analog audio input 1 from the Laptop;
– the analog audio input 2 from the Media player.

Only one mode can be used at the same time: Control mode, or Pass-through mode, or Command Injection
mode. If you choose one of them, TPS serial link and local RS-232 port will operate in the same mode.
Pass-through Mode
In pass-through mode, the given device forwards the data that is coming from one of its ports to another same
type of port. The command is not processed by the CPU. Incoming serial data is forwarded from local RS-232
port to the TPS output port and vica versa inside the transmitter.
