Note

Centric
supports the UPS MIB (Management Information Base) standard.
7.2.7.3
SERIAL COMMUNICATION (OPTIONAL FEATURE)
Serial communication is an optional feature, available by special order.
This option enables serial communication between the
Centric
and an external device. Indicate the port to
be used and the baud rate. Choose one of the ports from the list.
If your system includes this option, the serial communication connector is labeled "RS232" and is located
on the left side of the static switch on the rear side of the UPS.
Figure 37: Defining serial communication parameters
Note: If the serial communication option is ordered as an add-on to an existing system, the physical
connection details may be other than described above.
7.2.7.4
MODBUS (OPTIONAL FEATURE)
The ability to use a Modbus link with the
Centric
is an optional feature, available by special order. A
password may be required to use this feature. If you do not have the appropriate password, contact your
distributor or sales agent.
Two types of Modbus links can be defined between the Centric and another device on the network: a serial
link or a TCP/IP link. The two types of links are not mutually exclusive. In either case, with regards to
Modbus, the Centric is a slave device to the Modbus master located elsewhere on the Modbus
communication network. The Centric will respond to queries from the Modbus master.
