Analog I/O terminal N81
62 pole D-sub connector (N81). Can be used
for connection of monitoring/recording
equipment. Only Siemens connection cable
must be used.
The illustration of the connector show
outside view.
If a signal has three different scale factor
values, e. g. 3/18/45 V/l/s, the different
values refers to selected front panel setting
Adult/Pediatric/Neonate.
Input control signals can be connected at
N81 to control some ventilator functions
(e.g. when using Bi-Phasic Ventilation).
These input signals are routed via two
sockets, J2 and J3, on PC 1587.

To enable the control functions, jumpers
must be mounted in the sockets. The figure
below, showing sockets J2 and J3, indicates
which connectors that need to be short-
circuited with a jumper to enable a control
signal. (Signal No. as stated in the pin
configuration list below.)
Note – If jumpers are mounted and a
voltage is connected to any of the pin
number marked * in the table below, the
function of the ventilator can be influenced.
