Introduction
Integrating an NV5100 master control switcher with an NV9000 control system allows the
NV9000 and associated systems (tally, automation, etc.) to monitor the state of the various buses
and effects within the NV5100 switcher.
NVISION NV5100MC and NV5128-MC master control systems are obsolete. Although these
systems are no longer manufactured, there is limited support for them in the field.
An NV5100 master control switcher is a MCPM or an MCE, and is not the NV5100 frame
containing MPCMs or MCEs.
Nevertheless, a master control switcher identified by your NV9000 configuration is treated as a
router and included among the routers listed in the ‘Routers’ page and the ‘Routers’ table.
The NV9000 polls the NV5100 MCPM or MCE as it does a router, but the data returned is more
extensive than simple crosspoint state. The MCPM or MCE is modeled as a 128-output router,
with the following configuration parameters:
Level number = 1
Level size = up to 65535 inputs and up to 128 outputs (defaults to 128 inputs and 4 outputs)
Shared control = TRUE
These parameters are to be defined in the ‘PhysLevels’ table.
The outputs of the master control level are defined as follows:
Output

input number)
3

Preset audio — the input of AES channel 1 (input is the AES input number not the mono
input number)
