NV9000-SE Utilities

User’s Guide

If you select ‘False’, the NV9000 software retains exclusive access to this physical level and
does not permit crosspoint changes that it does not initiate.

Router Type

This is probably the most critical field in the set of parameters: The choices for this field are

XY or standard

Most routers are X-Y routers, used for video and audio routing. They are called “X-Y” rout-
ers because they incorporate a 2D switching matrix.

X-Y routers stand in contrast to machine control routers because they have a crosspoint
matrix and routes are not bi-directional or point-to-point.

NVISION machine control

This router type is the exception in the NVISION series. Machine control routers are
treated differently from standard routers and must be identified.

Machine control routers transmit control signals from a “source” machine (such as a VTR)
to a “destination” machine and return status signals from the destination to the source.
Machine control routes are bi-directional and point-to-point.

NVISION profile

This is a special feature available for artificial or “virtual” routers created for the purpose
manipulating router levels that could not be otherwise controlled without the artificial
router. (You can get into such a situation if you try to use alien equipment that does not
play well with NV9000 concepts or NVISION series routers.)

NVISION profiles are also useful in supporting Kaleido multi-viewers.

See the

NVISION Profiles

on page 63.

‘Number Virtual XPTs’

If you router is to have virtual crosspoints, specify the number of such crosspoints here. Oth-
erwise, leave the field value at 0.

See

Virtual Crosspoints

on page 59.

Chop Interval

Some routers perform test function known colloquially as “chop.”

Not all NVISION series routers

support “chop.” A chop rapidly switches the selected destination between its current source and the

preset source.

If your router can perform chop (and at least one control panel is configured to initiate a
chop), then specify an interval in this field. The interval is expressed as a number of video
frames. The default value is 6 frames.

‘Virtual XPT Default Input’

If you router is to have virtual crosspoints, specify the default input here. Otherwise, the
value in the field does not matter.

Virtual Crosspoints
