If the operator takes A to Z, the NV9000 software “discovers” that input Z is virtually routed to R,
S, and T. Therefore, it routes A to R, S, and T as real routes.
Here, again, an input was taken to multiple outputs, and that fact was concealed from the oper-
ator. The operator’s control panel reports that A was taken to Z. The operator executed a single
take.
Other inputs can be taken to Z with a similar result: that input will be taken to R, S, and T.
Scenario 3
In this scenario, the setup is the same as for scenario 2:
If the operator now takes B to Z, the NV9000 software again “discovers” that input Z is virtually
routed to R, S, and T. Therefore, it routes B to R, S, and T as real routes.
The operator’s control panel reports that B was taken to Z. The operator executed a single take.
This scenario illustrates that any time an operator takes an input to virtual output V, the router
actually takes the input to the real outputs “connected” to virtual input V.
NVISION Profiles
Profiles are a concept developed to support external systems that must communicate with
NVISION routers over NVISION Ethernet protocol (NVEP) and do not have access to device infor-
mation, principally their port numbers.

could not properly issue takes in an NV9000 system
and required profiles to function with the NV9000. That probably has changed by now.
Using a profile, an external system can cause the NV9000 control system to perform an all-level
take by referring only to the profile.
To provide a profile, you create a virtual router (one that has no real existence) with a single
physical level and a virtual level to match the physical level. You include the virtual level in all
the devices you want to be able to switch from the external system.
You must also convey the physical level ID and the port numbers of the relevent devices to
the external system.
