How the Panels and Routing Switchers Communicate
A routing switcher is a module that switches items of broadcast equipment from a nominated source to a nominated
destination. All routing switchers in the system can be connected to other NK Series devices via the T-Bus control
system, and can be connected to a video referencing signal (see “
Connecting a Video Reference to NK Series
Routing Switchers ” on page 32).The NK-3G144 can be partitioned. Each partition may be assigned to a unique or
common switching level.
Switching
The control panel sends a switch request message to the routing switcher. The routing switcher recognizes the
request, sets the crosspoint, then sends a response to the panel.
Data Storage
The panel stores information on the menu, destination, level, breakaway, and machine control status. The routing
switcher stores the crosspoint status in its internal memory.
When the system is powered up, the routing switcher restores its crosspoint status. The control panel requests the
status of the routing switcher.
