Usage Example for Host Computer Software
This guide provides a detailed walkthrough on connecting the 6 DOF IMU sensor to the RainbowLink V2 using host computer software. The process includes hardware and software setup, configuring communication modes, and collecting real-time data such as acceleration and gyroscope values.
Hardware Preparation
- TEL0190 RainbowLink V2 ×1
- SEN0692 Gravity:6 DOF IMU Sensor ×1
Software Preparation
- Download and unzip the host computer software: Download Host Software
Operation Steps
- Connect the 6-axis IMU sensor to RainbowLink V2 correctly. Set the sensor communication mode DIP switch to UART, and the address switch to 0x4A.
- Open the host software, select the correct port, set the baud rate to the default 9600, and click Open Serial Port.
- Click Connect Device. The dynamic motion display of the 6-axis IMU sensor will appear on the left side of the interface.
- Click Collect Basic Data to view real-time data such as acceleration and gyroscope values.

Notes
- After enabling Collect Basic Data, the dynamic display on the left may slightly lag due to real-time synchronization of multi‑dimensional raw data. This is normal and will return to smooth once the function is disabled.
- For this 6-axis IMU sensor (accelerometer + gyroscope), only pitch and roll angles are valid and reliable. The yaw angle has significant drift and is not suitable for practical use.
Reason:
Pitch and roll angles can obtain a static reference from the gravity component of the accelerometer, and achieve stable output with dynamic gyro compensation.
Yaw angle has no external absolute reference and is calculated only by gyro integration; zero-bias drift causes error accumulation over time.
Suggestion:
If stable yaw angle data is required, use a 9-axis / 10-axis sensor equipped with a magnetometer instead.
