SonoMarc module

The SonoMarc module reads seat, radio and intercom state from a SonoMarc radio/intercom training system over its own HTTP and Server-Sent Events API, and publishes one entity per seat. It polls current state continuously and receives transmit, receive and push-to-talk activity events as they happen. Malfunctions are polled and their transitions are computed at the module’s capture interval, not received over the event stream.

What you need

• A running SonoMarc session on a reachable SonoMarc Core server, before this module’s capture session starts. This module waits for one - see Configure.

Interface Control Document

See Interface control document for REST and Server-Sent Events endpoints, session selection, seat and asset fields, event semantics and error behavior.

Pages

• Configure: connection, session selection and per-seat capture mode.
• Data produced: the entity and event model, including a setting that is always published false regardless of the actual radio state, and a few real ambiguities in the event stream.
• Troubleshooting: symptoms, causes and fixes.
