12.4 Large External Displays
Large external displays can be connected to the Solar-Log™ via two interfaces:
•
Connection via RS485
•
S0 pulse output
The connection via RS485 is preferred Cable lengths can be up to 1000 meters and the data which is dis-
played on the Solar-Log™ can specified.
Note!
It is not possible to connect a large external display on the RS485 / 422 C interface.
The large external display function is not enabled by default. To use a proxy Display advanced configura-
tion needs to be activated under Configuration | System.
Note!
If inverters that use the RS422 connection are connected to this interface (e.g. Fronius,
AEG, Riello), then it is not possible to connect a display to this bus.
If the display is connected via the same cable as the inverters, the display must be con-
figured accordingly in the interface parameters.
