 Just for your understanding, “NP0017” is the part number of the document that describes
the NVISION Ethernet protocol (NVEP). It has no real meaning in the master control control
system.
Configure the following parameters:
• NP0017 user ID.
 The default value should be used because the Imagestore 750 does not support the lock,
protect, and release functions of NVISION router crosspoints.
In future software releases, this setting may be used by the NV9000 to track and diagnose
the Imagestore 750’s lock, protect, release activity on router crosspoints.
• NP0017 mnemonic set.
Up to 10 alternative name sets for sources and destinations can be defined in the NV9000
configuration, using NV9000-SE Utilities.
Note: name sets must be standard ASCII.
This setting selects which name set is combined with the main name set when you create a
new master control configuration (before any channel-specific naming overrides).
• Post-tally delay.
When the Imagestore 750 instructs the NV9000 router control system to perform a router
switch, the NV9000 sends the switch command to the router and tallies back to the Images-
tore 750 at the same time.
The router still must complete a physical switch which takes a small but significant amount
of time depending on the physical characteristics of the router.
The value entered into the ‘post tally delay’ field is the worst-case router switching delay.
The value is expressed in frames. The Imagestore 750 uses this value to ensure the integrity
of A/B mixer output during transitions.
