# XDR Help

You can configure the mapping of various NMEA2000 entities to XDR records.

To set up such a mapping you select the category, the source of data (if the category has different sources) and the field (if the category has multiple fields).

You have to provide the name of the transducer for the XDR record.

Many of the NMEA2000 messages have an instance id (0..255) to allow for different sources of the data. You need to decide how do you want to map such IDs to XDR records.

- IGNORE: the instance id will be ignored
- AUTO: the instance will be appended to the transducer name: #123
- SINGLE: just map exactlly one instance to this transducer name

You can also decide if you want a both way mapping, i.e. also map received XDR records back to NMEA 2000.

Once you create a mapping the system will show an example of the generated XDR records (and the accepted ones).

To ease the set up the system will track received NMEA2000 data that it currently does not map. With clicking "Show Unmapped" you bring up such a list and for each found mapping there is a "+" button that will allow you to create a mapping for this record.

The set of handled PGNs that can be mapped to XDR records can be found in the documentation.
