Morningstar RSC-1, Communications Adapter for EIA-485/RS-232

Morningstar’s 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. The RSC-1 may be used with any Morningstar controller or inverter equipped with an RS-232 port. By converting to EIA-485, the RSC-1 allows up to 128 Morningstar products to communicate on the same communication bus and over much greater distances.

Typical configurations include: Networking several TriStar and/or TriStar-MPPT controllers, adding Morningstar’s PC Meterbus Adapters (MSC) for use with an RJ-11 port in multi-device networks, adding Morningstar’s Relay Driver to a network, and integrating any compatible Morningstar product into an existing EIA-485 network (such as those used by industrial control or SCADA systems). All data is transmitted in the form of MODBUS protocol.
