Communication connections<br />
!<br />
Via the communication connections (interfaces),<br />
operating data can be retrieved<br />
from the data memory with an external<br />
computer and specific operating settings<br />
made. Several communication interfaces<br />
are available: RS 232 and RS 485.<br />
The standard communication interface is<br />
the RS 232 interface, which is installed in<br />
all current PCs and notebooks. This interface<br />
allows you to establish contact with<br />
your PC immediately, using a connecting<br />
cable. The use of more than one <strong>solar</strong><br />
inverter or cable lengths of more than<br />
25 m requires the use of the RS 485<br />
interface.<br />
(Fig.) SUB-D connector for RS 232 connection<br />
Attention: RS 485+ and RS 485- are duplicated.<br />
This means that the cable entry and<br />
exit are additionally clamped.<br />
The RS 232 interface is connected directly<br />
to the outside of the housing via a SUB-D<br />
connector. The RS 485 interface is connected<br />
via the circuit board terminals and the<br />
corresponding M12 threaded cable glands<br />
in the housing.<br />
