All of the front panel switches have built-in LEDs that help in the operation. The
functions of front panel are carefully designed for intuitiveness. With just a little
practice, one can learn to quickly monitor and control the matrix.
3.1.1 Viewing Audio and Video Routings or “Ties”
There are three different ways to view a tie: Video & Audio, Video only, or
Audio only. The point of view can also be either from input side (where the
selected input is routed to), or from the output side (see which input is feeding the
selected output). You can also use the ▲ and ▼ buttons to quickly go through
and check status of all channels. Furthermore, during viewing of ties you can
make new ties.
3.1.1.1 Viewing ties by Video and Audio
Press and release both VID and AUD buttons so that the LEDs of the VID and
AUD buttons are lit, which indicates that you are going to view both together.
At this point you have to decide if you want to view from the point of view of the
input or the output side.
… To View from input side
Press and release any Input button, the backlit LED of that button will light, and
all the backlit LEDs for the outputs whose video and audio are both
currently tied
to this input will also light up solid.
Note
If there is audio breakaway, the output LED will not be lit. An example may be
that output #2 video is tied to input #7 while output #2 audio is tied to input 12.
In this case if you start the viewing from input #7, output #2 will not be lit even
though input 7 video is routed to it. To see video ties independently from audio
ties, only the Video or the Audio LED on the front panel should be lit, not both.
You can now use the ▲ and ▼ buttons to quickly go through all inputs.
You can also make new ties by hitting output buttons. New ties will not take
effect unless ENTER is hit (see next section).
When you are done viewing ties, to exit you can hit ENTER. If you don’t hit any
buttons, then after 8 sec the view function times out and all the input and output
LEDs will go out.
