and 18th connectors are unused. Thus, ports 9.1 through 9.16 and 18.1 through 18.16 do not
exist in the router. However, they are listed in the ‘Current’ table as if they did exist.
You might be tempted to route to these ports. MRC will let you do it, but in the router, nothing
will happen.
You must remember that every ninth disembedder connector and every ninth embedder
connector goes unused. But the numbering is more complex than that. Refer to the NV8500
port diagrams (shipped with the router) for exact details of which ports are used and which are
not.
Second Caveat
The port (sub)space of any input card is 144 audio ports. MADI input cards provide 64 input
ports. The remaining 80 ports of the card are unused.
The port (sub)space of any output card is 288 audio ports. MADI output cards provide 128
output ports. The remaining 160 ports of the card are unused.
MRC does not indicate unused (or unusable) ports, and in fact allows you to route to or from
unused ports. In the actual router, nothing will happen.
Using the Crosspoints Page
You can use the ‘Crosspoints’ page to view or set crosspoints (i.e., perform “takes”) on any router
level. You can also save and load crosspoint matrix data.
Crosspoint changes you make in this page are immediately made in the crosspoint matrix of the
router.
The Current, History and Salvo tabs in the upper region display similar crosspoint information:
The History tab features an ‘Undo History’ section for selecting previous crosspoint states. (See
The Incrementing Takes tab lets you perform multiple takes in sequence. (See
on page 100 for details.)
