Grass Valley NVision NP0016 Compatible Router

Driver Maturity

Production

Recommended for normal production use.

Caution

Compatibility Note: This information is a general guide and may be incomplete, may not match a specific project implementation, and is subject to change as supported products and versions evolve. Confirm the exact implementation and requirements for each project with Riedel and the relevant equipment vendor, then validate the required functions end to end in the target environment before deployment.

Minimum hi Version: v2.5.2

Overview

The Grass Valley^® NVision^™ NP0016 integration provides Crosspoint control, partition discovery, and status monitoring over TCP.

Network Requirements

Allow outbound TCP from hi to each configured NP0016 controller on Port 5194 by default.
No callback or inbound connection to hi is used.
Keep the plaintext control connection on a trusted management network.

Standards Conformance

Standard	Conformance	Notes
Grass Valley NP0016	Routing partition and status operations implemented	Vendor protocol no public-standards conformance claimed

Operator Workflow

UI Surface in hi: Routing Matrix and Inventory
Router Scope: The level 1 partition reported by the router controller
Routing Semantics: hi exposes the Sources, Destinations, and Crosspoints in the level 1 partition that the controller reports.
Notes for Operators Familiar with the Vendor's Own Tooling: Use vendor tooling for labels, lock/protect configuration, salvos, and engineering setup.

Connection Details

Property	Value
Protocol	NP0016 Binary
Transport	TCP
Default Port	5194
Authentication	None - NP0016 binary protocol does not include authentication
Encryption in Transit	None - plaintext TCP no TLS defined by this protocol
Connection Model	Persistent TCP with asynchronous status notifications
Required License	hiBase
Traffic Flow	Outbound from hi

Required Configuration

Parameter	Description	Default
Host / IP Address	IP address of the primary NVision router controller	-
Secondary Host / IP Address	Optional redundant router-controller address	-
Port	TCP port for NP0016 communication	5194
Enable polling for crosspoints	Poll the Crosspoint state instead of waiting for asynchronous change announcements. Enable only for legacy routers, such as the NV8288, that do not send them. In the Options group; set at creation or at runtime.	No
Video disconnect	Source number that hi routes to a Destination when an operator disconnects it leave empty if not used set at runtime	-
Set Primary Active	Operations button that makes the primary controller active and restarts initialization available at runtime when the primary controller is connected	-
Set Secondary Active	Operations button that makes the secondary controller active and restarts initialization available at runtime when the secondary controller is connected	-

Device-Side Setup

Follow Grass Valley NVision NP0016 Compatible Router Integration Configuration for the device-side and hi-side configuration steps.

Supported Features

Feature	Access	Exposed Operation and Scope
Crosspoint Take	Write-only	Route a Source to a Destination.
Crosspoint Interrogate	Read-only	Query the currently routed Source for Destinations.
Destination Status	Read-only	Read routed Source and lock state.
Partition and System Status	Read-only	Read available partitions/ranges, system health, and configuration information.
Asynchronous Status Registration	Read-only updates	Register for real-time Crosspoint change notifications.

Device Coverage

Potentially Compatible (Not Yet Verified) identifies compatibility candidates that use the same protocol or connection method. Device-specific configuration, firmware, and feature support can affect results.

This integration supports the Grass Valley NVISION range.

Supported Product Range

NP0016 support for these NVISION routers depends on the controller and its software release. The NV5128, NV7256, and NV8256 use an EM0374 controller card, and the NV8140 and NV8144 use an EM0666 or EM0833 controller card. The EM0833 controller card supports asynchronous status registration from software release 3.5. The EM0353, EM0374-00, EM0374-01, and EM0374-02 controller cards and the NVISION Compact Router do not support it.

Known Limitations

Validate the partition, status, and routing operations with the installed firmware during commissioning.
Controllers do not all support the same NP0016 message set. Only the EM0833 controller card supports Destination status changes, and it supports asynchronous status registration from software release 3.5. If status updates do not arrive, use crosspoint polling.
The number of entries per Take or status request is limited, and the limit depends on the router type. Compact Routers have the tightest limits.
hi creates Sources and Destinations from the level 1 partition that the controller reports, and it registers for Crosspoint changes on that level only. Other levels do not appear in hi.
hi requests the status of at most 64 Destinations in one Destination status request.
When hi connects to a controller pair and finds no active controller, it retries after 30 seconds. When the active controller changes, hi restarts initialization on the new active controller.
When Enable polling for crosspoints is on, hi does not register for change announcements. It requests the Destination status in turn, and it pauses polling while other data moves on the connection. A change to this setting restarts initialization.
A Compact Router that detects no other Compact Router or Remote Panel on its subnet resets its network adaptor after about 120 seconds. An optional UDP Broadcast Data Integrity Message prevents this reset, and hi does not send this message.

What's Not Supported

NV9000 external control (NP0017) is a separate vendor protocol and is not part of this integration.
Label management through NP0016; use the router's native configuration interface.
Engineering-level configuration (level naming, port labels, redundancy setup) - use the vendor's native router-control tool.
Firmware updates - use the vendor's native update utility.
Hardware diagnostics and SFP-level health - surfaced by the device's own management plane, not this integration.
Partition selection. hi has no partition setting.
Setting Destination lock, protect, and release states (Set Destination LPR Request). hi reads the lock state only.
Coherent Take, Chop, and Machine Control Take requests.
Registration for Destination lock, protect, and release change announcements. hi registers for Crosspoint changes only and reads the lock state when it requests the Destination status.
