Whichever baud rate you choose through dip-switch 5, remember that:
the same RS232 connection speed must be set up on the remote
supervision unit
the baud rate which is selected through the dip-switch 5 sets the
connection speed for both the RS232 port and the RS485 port as the
TPRN uses both ports with the same rate.
RS485 port
The RS485 port consists of two RJ45 connectors, which can both work as
input or output ports towards a RS485 bus.
This RS485 bus has to be used in order to connect a multi sub-rack system to
the remote supervision unit. In this case:
the TPRN sub-racks have to be connected one another via RS485 bus
in a daisy chain;
In order to monitor the whole system, the remote supervision unit has
to be connected to one of the TPRN sub-racks through RS232 port.
Before connecting the TPRN sub-racks belonging to a multi-sub-rack system,
remember to assign an exclusive binary address to each one. This is essential
in order to let the supervision system recognize the different master units
without any conflict.
The binary address assignment can be done through dip-switches 1,2,3,4,
which stand on interior TPRN backplane (see figure 5.6). A list of the
correspondences between the addresses and the dip-switches is provided by
table 5.2: simply note that dip-switch 1 is the least significant binary digit,
while dip-switch 4 is the most significant one.
