Property Editor

Property Editor exposes the selected instrument's canonical data. This view is valuable when the instrument's user-friendly display uses different units, fewer decimals or an unavailable label.

Edit deliberately

  1. Select the instrument or its Object Tree entry.
  2. Read the parameter, value, units and type columns together.
  3. Edit a supported value in its canonical unit/type and commit using the available editor.
  4. Check the instrument, Property Editor and Object Tree agree in meaning, allowing for display rounding.

For example, 293.15 K corresponds to 20 °C and 68 °F. A preferred-unit change alters presentation, not the underlying Kelvin measurement. Coordinate displays may show degrees/minutes while the canonical decimal degrees retain more precision. Do not round canonical values simply to match a short label.

Understand rejected input

While typing, incomplete numeric text leaves the current value unchanged. Press Enter or leave the field to finish editing. Invalid or out-of-range input restores the current value in your selected units, including any newer RX/generator update received during editing. Values are not silently clamped.

Use the field's engineering range. Zero and negative values can be valid for some fields; unavailable, protocol error and reserved values are separate concepts. A visible Unavailable result is not an invitation to enter a raw wire sentinel.

Use structured editors for lists

  1. Open Edit records… or the message's waypoint/identifier editor rather than hand-editing serialized JSON.
  2. Add, edit or remove supported rows. Respect the visible count/length limits.
  3. Check instance/identifier fields and ordering, not only names.
  4. Accept the complete draft or Cancel it. A record-list edit is not a request to upload a route or change a chartplotter database.

Satellite, route and waypoint lists have message-specific limits. The bounded editor must reject an oversized fast packet rather than silently losing records. If values immediately change again after a valid edit, inspect generator Dispatch or incoming RX before assuming the editor failed.
