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: v2.2.0

Overview

Grass Valley^® Densité^™ cards and modules integrate through the Densité REST API on an AppServer. hi discovers cards, reads status, controls parameters, and polls for session updates.

Network Requirements

Connection Model: hi initiates HTTP requests to the AppServer.
Multicast / Unicast: Unicast only.
VLAN / IGMP: No multicast configuration is required.
Bandwidth: Control traffic only.
IP Version: IPv4.
Firewall: Allow outbound HTTP from hi to the Densité AppServer on TCP 5955.

Required Configuration

Parameter	Description	Default
Host / IP Address	IP address of the Densité AppServer	-
Port	Densité REST API Port	5955
Login Name	Densité AppServer account used by hi. Replace the default with a dedicated account.	admin

Device-Side Setup

Follow Grass Valley Densité Parameter Controllable Device Integration Configuration for the device-side and hi-side configuration steps.

Supported Features

Feature	Access	Exposed Operation and Scope
Card Parameters	Per-parameter access	Read card parameters and write parameters whose AppServer access metadata permits writes. Parameters not marked writable are presented as read-only in hi.
Card and Frame Status	Read-only	Query status exposed by the AppServer.
Card Discovery	Read-only	Discover installed cards through the AppServer.

Device Coverage

Tested With identifies devices that have been tested with hi. Potentially Compatible (Not Yet Verified) identifies devices that use the same protocol or connection method but have not been tested with hi. Device-specific configuration, firmware, and feature support can affect results.

This integration supports the Grass Valley Densité range.

Tested With

Grass Valley iControl Application Server

Supported Product Range

Grass Valley Densité 3 frames
Grass Valley Densité 3+ frames
Grass Valley Densité cards installed in those frames, for example XVP-3901, HCO-3901, and FRS-3901. The cards in a frame appear only if the AppServer exposes them.

Known Limitations

The integration exposes only parameters and status returned by the card's AppServer.
The AppServer delivers updates through a session and closes the session when its update buffer is not read for about 40 seconds. A network interruption longer than that requires a new session, so expect a resynchronization after a long outage.
hi checks the AppServer connection every 10 seconds. A failed check marks the Node as disconnected.
hi compares the card list of the AppServer with its own list every 60 seconds. When a card is added, removed, or changed, hi reinitializes the Node.
hi opens one update session for each frame that the AppServer reports.
Login Name and Password are in the Authentication group. They are available when you create the Node and afterward.

What's Not Supported

Direct card communication; the integration requires an AppServer.
Firmware updates, AppServer administration, and base hardware provisioning.
Reading or setting labels on the AppServer.
