A.6.2 Implemented Functions
The transmitter sends physiological data (such as ECG waveform and SpO
2
parameter)
and the transmitter status data (such as the status about lead, button, battery voltage,
and others) to the receiver via the wireless network, and then the receiver sends those
data to the central station (CS).
The ECG data precision sent to the CS from the transmitter is 200 Hz, 8 bit per channel.
The transmitter automatically networks with the CS after the transmitter is turned on.
The time from the boot to connecting with the CS network is less than or equal to 15
seconds.
The receiver can detect the wireless signal strength of the transmitter, and send the
information to the CS.
