Port & String Labels

LED.FYI generates human-readable labels for ports and strings to match the labeling conventions used on physical equipment.

Port Labels

Port labels identify which physical output port on the processor (or switch) a string is connected to. The format depends on the equipment:

• Direct 1G outputs — Labeled numerically (Port 1, Port 2, etc.)
• Switch ports — Labeled with the switch identifier and port number (e.g., "A1", "B3")

String Labels

Each string in a screen gets a label based on:

• The screen it belongs to
• Its position in the data path sequence
• The port it's assigned to

These labels appear in:

• The String Assignment sidebar panel
• The LED Mapping view
• The Panel Map test pattern overlay
• Exported paperwork and BOM documents

Backup Port Labels

When a backup port is assigned for a string, the port label updates to show both the primary and backup port in a combined format (e.g., A1/B3). The backup port label appears on the last panel of each redundant string in the Panel Map test pattern, the LED Mapping view, and exported paperwork.

See Data Redundancy for details on how backup ports work across different processor types.

Label Conventions

Labels follow industry conventions for the selected processor type, making it easy to match the on-screen configuration to your physical hardware. The label format is determined by the processor and switch specifications in the equipment library.
