The serial RS232 interface
Operating data can be transmitted to a computer (e.g. note-
book) over a galvanically isolated serial interface (see fi gure
4.1 - (6)) from where it can then be individually processed fur-
ther using standard spreadsheet software.
A standard serial 1:1 interface cable is all that is required for
connecting the inverter to the computer. The cable length
should not exceed 20 metres.
The data from the inverter is sent unidirectionally as pure
ASCII text over the serial interface. The data is not checked for
errors.
The RS232 interface has the following parameters:
Baud rate
Data bits
Parity
Stop bits

9600 baud

Figure 4.6 shows, as an example, a few of lines of transmis-
sion via the RS232 interface.
The interface of the connected PC or laptop must comply with
the standard for RS232 interfaces. Some computer manufac-
turers do not fully adhere to the standard. In such cases, prob-
lems may occur during data transmission.
Data can be received with any terminal emulator, which comes
with every operating system, or with the KACO-viso visualisa-
tion tool.
Together with the Powador inverter, KACO-viso takes over the
role of a data logger. It saves the data from the inverter and
displays it in various diagram types as a daily or monthly rep-
resentation.
The PC, however, must also run continuously. Because of the
amount of energy used, this type of monitoring only makes
sense over limited periods, such as during a fault analysis. For
permanent monitoring, we recommend the optional accesso-
ries (see section 5).

NOTICE
Calculating effi ciency by measuring the current and volt-
age values leads to unusable results due to the tolerances
of the measuring units.
The sole purpose of these values is to monitor the basic
operation of the system.
