4. Serial Communications Specifications
The BCUTE-AO Pulse Oximeter module communicates with the host computer through a single, high-speed asynchronous serial channel at TTL voltage levels. Data provided to the host includes %SpO2, Pulse Rate, Signal Strength, Bargraph, Plethysmogram, and Status Bits data. The host can send commands to control the averaging rates, enable/disable the auto synchronization of the Plethysmogram Waveform, request the Oximeter software revision level, setup the Baudrate, setup the sampling-rate.
4.1 Communication Protocol
There are 4 protocols available on the BCUTE-AO Pulse Oximeter module that also supports the BCI Communications Protocol.
