Standalone source cross-reference
A source cross-reference identifies the originating side of a diagram continuation relationship.

What it represents
A source cross-reference identifies the originating side of a diagram continuation relationship. This is a navigation and association element linking a circuit or signal to its continuation. Its source role is meaningful only when the matching destination reference is present.
Use consistent reference text, sheet identifiers and locations at both ends. Cosmetic source shapes do not create different circuit functions.
How to read it
- Provide the matching destination reference, sheet and location information.
- Rectangle, hexagon and ellipse presentation styles are kept as one source-reference concept.
Information to show or reference
- Identify the associated device, circuit or diagram boundary.
- Provide the matching destination reference, sheet and location information.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
A distinction that matters
Rectangle, hexagon and ellipse presentation styles are kept as one source-reference concept.
