Datex-Ohmeda S/5 Compact Anesthesia and Critical Care Monitor
WARNING
WARNING
Always make sure that the combination complies with the international safety
standard IEC 60601-1-1 for medical electrical systems and with the
requirements of local authorities.
Connecting the power supply cord of the computer to the wall socket may cause
the computer leakage current to exceed the limit specified for medical
equipment. Always connect the computer to an appropriate separating
transformer.

4.7.1 Digital outputs
The digital output signals are as follows:
Defibrillation Sync (X8 pin 2)
The defibrillation sync signal is generated by the ECG. When activated, the signal is set to a high
level and then set back to a low level after 10 ms. The signal is regenerated only after returning to
the low level. The high level ranges from 2.8 to 5 V while the low level ranges from 0 to 0.8 V. The
delay from the R wave peak to the start of the signal is 35 ms maximum.
Nurse Call (X4 pin 8)
The nurse call signal is generated by the red, yellow and white alarms. When activated, the signal is
set to the high state and remains at the high state until the alarm situation is over or the SILENCE
ALARM key is pressed. The high state range is from 2.8 to 5 V, while the low state range is from 0 to
0.8 V.
If the output signals are used simultaneously with the coding element, the B-UPINET Y-cable, order
