Setting the dip-switches in a multi sub-rack system
If you are installing a multi-sub-rack system, remember to assign each sub-
rack an exclusive binary address, by properly setting dip-switches 1,2,3,4 on
the interior TPRN backplane (see fig. 5.6 and Tab.5.2). Dip-switch 5 has to be
set on each TPRN sub-rack in order to fix the baud rate for RS485 and RS232
port. Connecting TPRNs through RS485 port is necessary when supervising
the whole multi sub-rack system through the remote supervision unit (to be
set at the same baud rate).
TPRN Installation
The TPRN kit provides:
• 1 TPRN sub-rack
• 1 suitable power cord
• 1 standard RS232 cable (male-female), 2m
• 1 CD Manual
First of all insert the sub-rack into the cabinet and apply 4 screws (not
provided) in order to fix it (fig. 5.8a).
To have a correct TPRN installation, distance between the front
door of the rack and the front side of the TPRN should be at
least 15cm otherwise RF and optical cables can be damaged
when cabinet door is closed.
Leave at least 1HE distance between two subracks
in order to facilitate air circulation.
Leave at least a 1HE free space between the
bottom or the top of the cabinet and the TPRNs.
Connect the ground to the safety ground terminal. Then, connect the power
supply connector to the mains.
