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 loop redundancy is enabled, each string also shows a backup port label indicating which redundancy port provides backup for that string.

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.
