Lightware UMX-TPS-TX100 Series

3. Product Overview UMX-TPS-TX100 series – User's Manual 31
Automatic Input Selection - Example
The Concept
If there is no other source connected to the transmitter, but the Laptop, VGA input will be automatically
switched to the TPS output. If the Laptop and the PC are also connected to the transmitter, DVI-D input will
be switched to the TPS output. If the Blu-ray player is connected on the HDMI input, and later the MacBook
is connected on the DP input of the transmitter, it will be switched to the TPS output – independently of the
presence of other video signals.
Settings
▪ TPS output: Set the Autoselect to Enabled. Set Autoselect mode to Priority detect. The priorities are the
following (the lowest number means the highest priority):
Source device Input interface Input port Priority
MacBook DP IN I3 0
Blu-ray player HDMI IN I2 1
PC DVI-D IN I4 2
Laptop VGA IN I1 3
Priorities can be set in Lightware Device Controller software, see related settings in the TPS Video Output
and the TPS Audio Output sections.

Audio Embedding
The transmitter has a built-in audio embedder function which means the audio signal being received on the
analog audio input port can be embedded to the TPS output.
