BTN604 blood oxygen module is a module that can be used to monitor patients' blood oxygen saturation and pulse rate. It is compatible with all BCI probes and is suitable for infants, newborns and adults.
The BTN604 is a compact, high‑reliability blood‑oxygen (SpO₂) and pulse‑rate monitoring module designed for use with adult, infant and newborn patients. It operates at 3.3 V, supports RS‑232 serial communication, and is compatible with BCI‑type probes.
The manual covers product features, safety warnings, electrical specifications, pin‑out diagrams, serial‑port protocol (4800 baud, 8‑N‑1), installation procedures, verification using a blood‑oxygen simulator, and warranty/maintenance instructions. This manual is written in Chinese.
