User Manual
WTI400 v1.2 — In service on the test vessel (~1,000 sea miles), running a simple PlatformIO/Arduino firmware that emits NMEA 2000 wind sentences.
The User Manual covers the operator-facing workflow of the WTI400 — installation, transducer wiring, IMU calibration, status LED and button operation, and troubleshooting.
The operator manual for the WTI400 V1.2 is not yet available.
The WTI400 is in service today, running a simple PlatformIO/Arduino firmware that emits NMEA 2000 wind sentences. Its operator-facing behaviour exists and works in the field; what is pending is a documentation pass of the in-service workflow — installation, transducer wiring, IMU calibration, status LED and button operation, and troubleshooting.
The WTI400's local UI is a single RGB LED + tactile button on the front face. The red channel lights by default at power-on as a power-good indicator, before firmware initialises; firmware then drives the three colour channels to signal device state and respond to button input. The planned Status LED and Fault-finding pages below will cover how to read it; see LED Indicator in the Circuit Design section for the full hardware behaviour.
This section will be published once the in-service operator workflow has been documented. For the installed-firmware status and the planned production ESP-IDF migration, see the Firmware section and the Tasks page.
| Planned page | What it will cover |
|---|---|
| Quick Start | Connect to the NMEA 2000 backbone, attach the wind transducer, power on |
| Installation | Mounting, transducer wiring at the six quick-connect tabs, JP1 supply-setpoint selection |
| Calibration | IMU heel/pitch reference setup and wind ADC limits / midpoint scheme |
| Status LED | What the RGB indicator colours mean and how the button responds |
| Common Pitfalls | Mistakes to avoid during installation and use |
| Fault-finding | Reading the front-face RGB status LED and other on-unit checks to diagnose a fault |
| Troubleshooting | Diagnosing and resolving common faults |
