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-Oximeterocking 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.

ANALOG OUTPUT
The Radical-7 Pulse CO-Oximeter can interface with various analog recording devices
and/or strip chart recorders through its Analog Output connector located on the back of the
Docking Station. Depending on the configuration of the Output menu, the following param-
eters are output continuously on the Analog 1 and Analog 2 channels:
■ SpO
2
■ SpCO
■ SpMet
■ Pulse rate
■ Pleth waveform
■ Signal IQ
The output signals vary from approximately 0 to 1 volt in a linear fashion.
NOTE: The actual Analog 1 and Analog 2 output voltage that are generated may not
exactly range between 0.0V to 1.0V. A variance of ± 40 mV is acceptable.
CALIBRATION
For measurement device calibration purposes, the analog output signals can be set to
either 0 Volts or 1 Volt in the menu system under Output/Analog Output Mode. Calibrate
your analog recording system to those levels before use.
NURSE CALL
The nurse call feature is available when Radical-7 Pulse CO-Oximeter is operating in its
standalone configuration. The nurse call feature on the Radical-7 Pulse CO-Oximeter is
based on the relay closing or opening depending on alarm, Low Signal IQ events or both.
For maximum flexibility, either normally open (pin 6) or normally closed (pin 7) signals
are available. Only qualified personnel should connect one of these two signals and
common (pin 12) to a hospital’s nurse call system. During an alarm condition, or a Low
Signal IQ event, depending on the configuration of the output menu, the normally open
pin will be connected to the common pin and the normally closed will be disconnected.
In addition the nurse call polarity can be inverted to accommodate various nurse call
stations requirements.
The nurse call relays have the following electrical specifications per switch:
PARAMETER SPECIFICATION
MAX VOLTAGE
100VDC or AC peak
MAX CURRENT
100mA
WARNING: THE NURSE CALL FEATURE IS DISABLED WHEN THE AUDIBLE
ALARMS ARE SILENCED WHILE THE NURSE CALL SETTING IN
THE OUTPUT MENU IS SET TO “ALARMS”.
