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

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

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.

RS-232 cable for components is included. Null modem crossover cable for PC is not included.

RSC-1 Adapter Features

• Removable four (4) position EIA-485 terminal
• 9-pin RS-232 connector (male)
• Status LED for monitoring and diagnostics
• Molded tabs for attachment to 35mm standard DIN rail
• RS-232 ribbon cable with low-profile connectors

Typical example of an EIA-485 Modbus network using multiple Morningstar products.

What is the Modbus Protocol?

MODBUS® Protocol is a messaging structure developed by Modicon in 1979, used to establish master-slave/client-server communication between intelligent devices. It is a de facto standard, truly open and the most widely used network protocol in the industrial manufacturing environment. It is literally implemented by hundreds of vendors on thousands of different devices in order to transfer discrete/analog I/O and register data between control devices. It’s really a lingua franca or common denominator between different manufacturers. One report called it the “de facto standard in multi-vendor integration”.
