6.1.4 Configuration
The communication interface does not have to be configured in or-
der to connect the PV inverter to the data logger system of the
AEG "PV.LoG". Once the bus cable has been installed and the
system has been powered up, the configuration settings are made
fully automatically.
If you are using a different/in-house monitoring system, you can
adjust the transmission parameters and the slave address of the
Modbus interface to suit your requirements via port 1 (X2). We
would be happy to provide you with the Modbus unit profile on re-
quest.
6.1.4.1 Configuration Preparations
You will need a 1:1 data line and a PC.
To carry out the configuration, you must now connect the PC to
the MultiCom interface (X2) with the data line and start a termi-
nal program, such as HyperTerminal, on the PC.
Setting the terminal program:
Data transmission: COMx, 9600 baud/8 data bits/1 stop
bit
No parity/no protocol
Terminal emulation: VT100
You can then start the configuration by pressing the "S1" but-
ton on the MultiCom interface. You must make sure that no com-
munication has taken place via the X2/X5 interfaces for at least the
previous 10 seconds.
The start of the configuration is indicated by two flashing LEDs on
the MultiCom interface and by the following message on the termi-
nal display:
„PRESS <CR> FOR CONFIGURATION WHILE LED IS
FLASHING"
The configuration starts, providing you press the <ENTER> key
(<CR>) within 30 seconds. The configuration main menu is
opened:
