Serial interface converted to standard interface
The new MRC-1 converts the Morningstar MeterBus RJ-11 serial interface to a standard EIA-485 interface. By providing isolated power out to a 485 network, this device eliminates the need for an external bus power source in many applications, for example, a separate 24V-12V converter on 24V systems. This product is compatible with GenStar MPPT solar DC system controllers, ProStar MPPT and PWM controllers, SunSaver MPPT controllers, and SunSaver Duo controllers. It enables Morningstar products with a Meterbus port, but without a native EIA-485 communications port, to network with Morningstar EIA-485 devices such as the GenStar and TriStar MPPT controllers (select Morningstar devices support Modbus or Modbus TCP/IP communication via serial EIA-485, RS-232 or Ethernet (RJ-45) ports). It can also be used for EIA-485 communications with any third-party hardware that supports Modbus communication. Once powered on, connected EIA-485 network devices will be enabled with the communications bus powered by a connected Meterbus device. It includes RJ-11 cable and reverse-polarity protection at the EIA-485 terminals.
