This manual explains the setup, hardware preparation, operation flow, and demonstration of the VDU4505 UWBTWR active positioning system.
The VDU4505 UWBTWR active positioning system consists of a UWB ranging base station and tags (helmet, chest, etc.) that enable precise indoor location tracking. The system can be built using the VDU2506 base station or the SKU620 core module, and tags are powered by rechargeable batteries.
The manual guides users through hardware installation requirements, tag ID acquisition via Bluetooth, software configuration steps, and how to start coordinate conversion and view real‑time positioning results. Contact information for 95Power support is provided at the end. This manual is written in Chinese.
