Design & Development of Annunciator . For a California based Company redesigned their annunciators around modern technology. The annunciators could handle 1 to 128 input modules with inputs to display from 8 to 1024 zones. The original full analog design was simplified with a single main PCB with a powerful microcontroller and multiple smaller PCBs with smaller microcontrollers, Analog & Digital inputs and outputs. PC based Software was developed to configure the system for multiple parameters. The duration of the project was 8 months.Test jigs were replicated at both places (USA & Goa, India).
