Abstract
A system for displaying statuses for multiple signal paths or ports on LEDs is disclosed. The system comprising a plurality of shift circuits receives a data signal comprising groups of status signals. The data signal is serially shifted from one shift circuit to another so as to parse the status signals to be displayed on appropriate LEDs designated for each of the signal paths or ports. As a result, multiple statuses can be effectively displayed in real time using a minimum number of LEDs.
