SERIAL PORT MUST BE IEC-60950 COMPLIANT.
Analog Output/Nurse Call Specifications
The Analog Out and Nurse Call are features accessible on the same female high density
DB-15 connector.
NOTE: The Radical-7 Pulse CO-Oximeter analog output / nurse call interface is only available when
the Radical-7 Pulse CO-Oximeter Handheld is properly attached to the Radical-7 Pulse CO-Oximeter
Docking Station. Only use an analog / nurse call cable that has a ferrite bead installed.
NOTE: The analog output / nurse call interface is not available in all versions of the Docking Station.
The following table shows the pinout of the analog output and nurse call.
