Main unit features:
1) Utilizes industrial-grade CONTEX-M3 CPU for direct hardware control, independently developed with full intellectual property. Closed 32-bit proprietary encrypted operating system ensures stability and security, avoiding public network virus interference. Closed-source system, boots in seconds, not Android-based.
2) Dual-chip data storage backup with capacity for 60,000 to 120,000 records. Full-process voice prompts (adjustable volume and mute option). 7-inch touch color display with adjustable backlight brightness (touchscreen enables all functions).
3) Standard audio interface for external speakers; charging indicator and USB insertion indicator lights.
4) ≥2 USB ports; built-in imaging QR code and barcode scanner (quick participant data entry); mechanical keypad input for test numbers (supports touchscreen full keyboard input for alphanumeric test IDs); batch import of participant data via USB for rapid roll call testing; incremental numbering function for efficient data entry.
5) Menu-driven WYSIWYG interface with full voice guidance for intuitive operation. Operators cannot delete test data—only administrators have data management privileges.
6) Fully wireless data networking supports real-time or batch transmission using 2.4G communication (long-range large-scale networking). High-power high-frequency wireless module offers long transmission distance, strong diffraction penetration, and large network capacity. Closed-loop local self-organizing network avoids public network virus interference; open-field transmission range up to 2 km.
7) Silicone keys with long lifespan; 4×5 matrix 20-key multifunctional design tested for 100,000 cycles durability. Anti-slip texture prevents miskeying.
8) Dual power supply (DC/AC); built-in high-capacity lithium battery supports 10+ hours continuous operation with real-time power level display.
9) Universal host allows instant peripheral pairing via menu/touchscreen without reprogramming. All peripherals communicate via ANT 2.4G protocol.
10) Test data can be exported via USB to PC fitness test management software (eliminates long wait for batch uploads and allows offline data collection).
