Problem
Problem and constraints
Model-specific scripts, undocumented command tables, and unreliable serial workflows made mixed instruments difficult to operate and maintain. Operators and developers needed consistent controls and diagnostics across supported devices.
Engineering approachArchitecture and implementation
A registry-driven driver layer keeps model behavior in YAML specifications and protocol codecs. Acquisition workers isolate transport timing from the UI, while simulated gauges exercise the same operator paths without connected equipment.
Registry
Model defaults, commands, transport constraints, and support status resolve from explicit device specifications.
Runtime
Polling workers emit structured readings and errors without allowing serial faults to freeze the interface.
Diagnostics and records
Saved sessions, traffic inspection, multi-gauge plots, and exports support review of instrument runs.
