Communication connections
!
Via the communication connections (inter- faces), operating data can be retrieved from the data memory with an external computer and specific operating settings made. Two interfaces are available:
RS 232 and RS 485.
The standard communication interface is the RS 232 interface, which is installed in all current PCs and notebooks. This inter- face allows you to establish contact with your PC immediately, using a connecting cable. The use of more than one solar inverter or cable lengths of more than 50 m requires the use of the RS 485 interface.
The connections for the RS 232 or RS 485 interface supply cable are also made via circuit board terminals and via the M12 screwed cable glands in the cabinet.

Attention: RS 485+ and RS 485- are dupli- cated. This means that the cable entry and exit are additionally clamped.
