4.7.1 UPI4NET Board output signals
Analog/ digital output signals on the connectors X7 can be used for interfacing with other
devices. The pin assignments are illustrated in tables/pictures below.

4.7.2 Digital outputs
The digital output signals are as follows:
Defibrillation Sync B-UPI4NET -02 (X7 pin1),
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 red and yellow 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 level range is from 2.8 to 5 V, while low state range is from 0 to
0.8 V.
