Navigator GUI System Windows in Detail
System Crosspoint Tab
This window is the main crosspoint window for the GUI. It is used to make/break/
view crosspoint connections. In a LAN based audio network, just what is a crosspoint
connection? After all, there is no audio router or patch bay to make audio connections.
Simply put, a crosspoint connection represents a message that a particular destination
(i.e. network address) wants to subscribe to the multicast packets representing a
particular audio stream. The Ethernet switch obliges by forwarding those packets along
to the subscribing device. In the Navigator GUI, this is shown as a dot at the grid
intersection of the source (multicast stream) and destination (subscribing device).
In the most basic view, the System Crosspoint window shows all of the system
sources across the top and all of the system destinations vertically on the left. The default
view has these signals shown first in numerical order of the BLADEs, and alphabetically
by signal name within the BLADE. Furthermore, each BLADE has a color, and the
BLADE’s signals are shown printed in matching color. This is meant to help identify
which signals go with which BLADE.
