Morningstar MSC PC MeterBus Adapter RJ-11 to RS-232

The Morningstar MSC PC Meterbus Adapter converts a controller’s meter port (RJ-11 phone type connector) to a standard RS-232 serial connector for connection to a PC or other equipment. The MSC may be used with any Morningstar controller or inverter equipped with a meter connection that does not also already have a RS-232 port.

By converting to RS-232, the MSC allows Morningstar’s controllers and inverters to communicate with a variety of third party serial enabled devices such as:

• A PC running Morningstar’s MS View software or any other compatible software.
• A serial enabled device such as an internet gateway.
• Another MODBUS enabled hardware device at the site that needs to access solar system information.

Establishing a communications link enables the monitoring or logging of data from the controller or inverter as well as the customizing of any user-adjustable settings. The MSC makes available a wide variety of data stored in Morningstar’s products such as (varies by product):

• Battery Voltage (including minimum and maximum)
• Solar charge current to the battery
• Load current from the battery
• Accumulated solar and load amp hours
• Charge Stage
• Errors and alarms
• Local and battery temperature
• Data logging files

All data is transmitted in the form of MODBUS protocol. This industry standard was chosen for a high level of compatibility with a variety of equipment. Each Morningstar product has its own data specification (see our website for full details).
