The baud rate of the RS485 ports is the same of the RS232 port as per the
dip-switch 5 setting.
Whichever baud rate you choose, remember that:
the same RS485 connection speed has to be set up on all the
connected device (TPRN sub-racks or TSUN remote supervision unit);
the baud-rate which is selected through the dip-switch 5 sets the
connection speed for both the RS485 port and the RS232 port.
Sub-D 15 poles male connector
The TPRN sub-rack provides a sub-D 15 poles male connector, shown in fig.

PIN Name Meaning
1
Ground It is a ground terminal for digital inputs, i.e. for pin 2, 3, 9, 10.
2
Digital input n.1
(SW assignable)
This port can be used to monitor external equipment status. Once a default
working status has been assigned (through supervision system) to this input port,
any change is detected as a failure signal.
3
Digital input n.2
(SW assignable)
This port can be used to monitor external equipment status. Once a default
working status has been assigned (through supervision system) to this input port,
any change is detected as a failure signal.
4
Disconnected pin No meaning
5,6
Summary of
major alarms
These pins present an open circuit if a major alarm is active on the TPRN sub-
rack or on any module hosted in it.
7,8
Summary of
minor alarms
These pins present an open circuit if a minor alarm is active on the TPRN sub-
rack or on any module hosted in it.
9
Digital input n.3
(SW assignable)
This port can be used to monitor external equipment status. Once a default
working status has been assigned (through supervision system) to this input port,
any change is detected as a failure signal.
10
Digital input n.4
(SW assignable)
This port can be used to monitor external equipment status. Once a default
working status has been assigned (through supervision system) to this input port,
any change is detected as a failure signal.
11
Disconnected pin No meaning
12,13
Digital output n.1
(SW assignable)
These pins are terminals of an output port (output relay 1), which can be driven
through the supervision system. The output port can be set to “open” or “close”
condition. These 2 statuses can be used to pilot any external device connected to
subD-15 connector.
14,15
Digital output n.2
(SW assignable)
These pins are terminals of an output port (output relay 2), which can be driven
through the supervision system. The output port can be set to “open” or “close”
condition. These 2 statuses can be used to pilot any external device connected to
subD-15 connector.
