LIN-Otter
Professional-grade LIN Bus Analyzer built for harsh environments.
Industrial debugging made simple. Analyze, capture, and simulate LIN bus communications with professional-grade hardware designed for real-world conditions.
Built different. For a reason.
Every feature designed to solve real problems engineers face in the field.
Ditch the laptop. Free your hands.
Stop dragging fragile laptops into tight, dirty, grease-covered field environments. This rugged handheld analyzer gives you complete independence.
Auto-Baud Lock | Data Filtering
Tired of manually configuring settings and sorting through junk data? LIN-Otter locks onto baud rates instantly with hardware-level precision. Filter out repeating spam and spot anomalies in real-time.
Rock-solid power. Noise-free data.
Decoupled dual inputs feature a standard DC jack and a high-retention Phoenix terminal, rock-solid at 16V for unpredictable field use. Integrated deduplication logic instantly silences repeating bus spam.
Software that works for you.
Intuitive GUI for quick debugging. Powerful CLI for automation. Full API access for custom integrations. Cross-platform: Windows, macOS, and Linux.
Bluetooth notifications anywhere.
Get instant alerts on your smartphone or laptop via Bluetooth. No wires, no hassle—stay connected to your LIN bus even when you're across the shop.
Buzzer confirms success instantly.
Hear when the problem is fixed. The built-in buzzer provides clear, immediate audio confirmation so you don't have to stare at a screen while working.
Custom responses to master requests.
Program exactly how your slave device responds. Test edge cases, validate master behavior, and simulate fault conditions with full control over every response.
Send custom packets on demand.
Take control as the bus master. Construct and transmit custom LIN frames to test slave devices, verify communication protocols, and validate your entire system.
