Masimo SET Pulse
Oximetry (SpO
2
)
Cable Connector
The pulse oximetry function uses an 11-pin, female, “Nicolay-style”
pulse oximetry connector. Special keying only allows the use of Masimo
LNOP (low noise) probes. The pinout is as follows:
Temperature/CO
Cable Connector The temperature/CO function uses an 11-pin, female connector. The
pinout is as follows:
PIN SIGNAL NAME I/O DESCRIPTION DIAGRAM
