Example node definition

A minimal entry in config.json looks like the block below. Paste it under the sources key, keyed by an instance name of your choice. All settings are optional: anything not listed under settings uses the default from the Properties table above. See The configuration file for how the sections and endpoint wiring work.

{
  "sources": {
    "RTCM": {
      "outEndpoint": "inproc://RTCM_data",
      "type": "ntrip",
      "settings": {}
    }
  }
}
