The digital interface for serial communication is based on the standard RS-232 protocol.
The Rad-8 pulse oximeter by default always outputs ASCII2 text data through the serial
port, unless the user selects a different output mode in the Output menu. To interface with
the Rad-8 and receive serial text data, simply connect a serial interface cable to the serial
output connector located on the back of the Rad-8.
NOTE:
Trend data packets are collected at 2 second intervals. Each data packet contains:
the date, time, SpO
2
, pulse rate, perfusion index and alarm and exception values (in ASCII
format).

1 Masimo SET technology with LNOP Adt/ Neo sensors has been validated for no motion accuracy in human blood studies on healthy
adult male and female volunteers with light to dark skin pigmentation in induced hypoxia studies in the range of 70-100% SpO
2
against
a laboratory co-oximeter and ECG monitor. This variation equals plus or minus one standard deviation which encompasses 68% of
the population. The saturation accuracy of the neonatal sensors were validated on adult male and female volunteers with light to dark
skin pigmentation and 1% was added to account for the properties of fetal hemoglobin.
2 Masimo SET technology with LNOP Adt sensors has been validated for motion accuracy in human blood studies on healthy adult male
and female volunteers with light to dark skin pigmentation in induced hypoxia studies while performing rubbing and tapping motions, at
2 to 4 Hz at an amplitude of 1 to 2 cm and a non-repetitive motion between 1 to 4Hz at an amplitude of 2 to 3 cm in induced hypoxia
studies in the range of 70-100% SpO
2
against a laboratory CO-oximeter and ECG monitor. This variation equals plus or minus one
standard deviation which encompasses 68% of the population. The saturation accuracy of the neonatal sensors were validated on adult
male and female volunteers with light to dark skin pigmentation and 1% was added to account for the properties of fetal hemoglobin.
3 Masimo SET technology has been validated for low perfusion accuracy in bench top testing against a Biotek Index 2 simulator and
Masimo’s simulator with signal strengths of greater than 0.02% and a % transmission of greater than 5% for saturations ranging from
70 to 100%. This variation equals plus or minus one standard deviation which encompasses 68% of the population.
4 This represents approximate run time at lowest indicator brightness and pulse tone turned off using a fully charged battery.
5 With FastSat the averaging time is dependent on the input signal. For the 2 and 4 second settings the averaging time may range from
2-4 and 4-6 seconds, respectively.
