Tracor Westronics SDI 310 CPU board

The Tracor Westronics SDI 310 is a digital chart‑recorder system that multiplexes sensor inputs to remote MX60 units and displays data on an integrated keypad/display module. Common failures include loss of the display/keypad interface and failure of the ADC card, often triggered by power outages or surge events, which manifests as “INVALID DATA” flashes across all points. Initial checks should verify mains voltage and UPS status, inspect the display and keypad connectors for corrosion or loose contacts, and test the ADC board with a multimeter to confirm proper supply rails and signal integrity before proceeding to component replacement.[oss-gpt-20b]
