3. Change the BAUD rate on each of the FIAMM battery
controllers.
Install RS485 Conductors in Parallel Between the NetSure 721
and Each of the FIAMM Batteries
In order for the NCU to communicate with any FIAMM 48TL200
battery(s), each FIAMM 48TL200 battery must parallel connect its’
respective RS485 (±) polarity terminal, between the NetSure 721
System Interface Circuit Card (P/N 556166) to the corresponding
FIAMM’s Com port.
Refer to the following documents for relative instructions:
FIAMM Technical Manual, ‘Installation & Operating
Instructions_48TL200_12-2014’.

Procedure
1. Install one (1) 18 AWG conductor per polarity, parallel
connecting between respective RS485 polarity terminals,
located on the NetSure 721 System Interface Circuit Card
(P/N 556166) and each of the FIAMM batteries.
Changing FIAMM Batteries ModBus Address
FIAMM automatically assigns each battery with a default Modbus
number of ‘02’. In order for the NCU to communicate with
multiple FIAMM 48TL200 batteries, each battery must have its
respective address changed to one of the Modbus numbers noted
below.
Modbus Number Assignment
o Regardless of which battery is chosen for the first
Modbus assignment, assign the first battery with
Modbus #6.
o Assign any additional batteries using whole numbers
only, up to #13.
o Note only a maximum of (8) batteries can be
monitored using the NCU.
NOTE: Remember to STOP the SMC Monitor software
communication before upgrading any software changes.
Refer to the following FIAMM documents for relative instructions:
FIAMM Technical Bulletin, ‘48TL200 Modbus Protocol’,
(Revision 5, Issue Date 21/05/2012), Section “Setting a
new MODBUS address”.
FIAMM User Manual, ‘48TL200 SMC Monitor’, (Revision 0,
Issue Date 27/08/2012), Section “FW Update”.
Procedure
1. Change the Modbus Address of each of the FIAMM
batteries by following instructions listed in the
referenced FIAMM Document, ‘48TL200_Modbus
Protocol’, Section ‘Setting a new MODBUS address’.
Changing FIAMM Battery Controllers BAUD Rate
In order for the NCU to communicate with any FIAMM 48TL200
batteries, each FIAMM 48TL200 battery must have its respective
BAUD rate changed to match the NCU controller’s BAUD rate of
9600.
As noted in FIAMM Technical Bulletin, ‘48TL200 Modbus Protocol’,
(Revision 5, Issue Date 21/05/2012), the default BAUD Rate is set
in the FIAMM controller at 115.2k.
User is to upload the file, ‘48TL200-Baud-rate-9600.xml', into each
FIAMM battery's separate controller, applying the respective
software BAUD Rate adjustment to each 48TL200 battery using
the upgrade utility instructions as described in the User Manual
referenced below.
After the upload is complete, the User is to toggle the ON/Off
switch located on each of the effected batteries, for purpose of
applying the BAUD rate software changes to the controller.
Refer to the following FIAMM documents for relative instructions:
FIAMM Technical Bulletin, ‘48TL200 Modbus Protocol’,
(Revision 5, Issue Date 21/05/2012), Section “Setting a
new MODBUS address”.
FIAMM User Manual, ‘48TL200 SMC Monitor’, (Revision 0,
Issue Date 27/08/2012), Section “FW Update”.
Procedure
1. Change the BAUD rate on each of the FIAMM batteries by
following the same “SMCMonitor200.exe” program
instructions as noted for changing Modbus Address,
described in the previous procedure, (referring again to
the instructions listed in referenced FIAMM Document,
‘48TL200_Modbus Protocol’, Section ‘Setting a new
MODBUS address’). However, for the changing of the
BAUD rate, a different operational ‘.xml’ file is to be used.
