Meterbus to EIA-485 Adapter [MRC-1]

The Meterbus-485 Adapter (Model: MRC-1), with RJ-11 cable included, converts the Morningstar MeterBus RJ-11 electrical interface to a standard EIA-485 interface. This allows Morningstar controllers or inverters with a MeterbusTM port, but without an EIA-485 communications port, to network with Morningstar EIA-485 devices like the GenStar and TriStar MPPT controllers. The MRC-1 can also be used for EIA-485 communications with any 3rd party hardware that supports Modbus communication.

Key Features and Benefits
  • The MRC-1 is protected against reverse polarity at its EIA-485 power terminals
  • The MRC-1 supports a four wire EIA-485 bus: GND, Data A, Data B, Power. A networked GenStar
    MPPT will use only three (3) wires: GND, Data A, Data B. Data A and B are differentially driven lines
    that carry the network data
  • The MRC-1is capable of supplying isolated power to an EIA-485 network, eliminating the need for
    an external bus power source in many cases
  • Five year limited warranty
