The Morningstar EIA-485 / RS-232 Communications Adapter (RSC-1) enables networking capability by converting a controller or inverter’s RS-232 port to a standard EIA-485 serial connector using the standard MODBUS protocol.
By converting to EIA-485, the RSC-1 allows up to 128 Morningstar products to communicate on the same communication bus over much greater distances than RS-232. The RSC-1 may be used with any Morningstar controller or inverter equipped with an RS-232 port.
