## Summary description

The Riello MULTICOM-302 is a protocol converter designed for UPS systems, featuring a green color. It enhances communication between devices, ensuring reliable performance and compatibility with various systems.

## Long description

The Riello MULTICOM-302 protocol converter enables monitoring and communication for UPS systems and transfer switches via Modbus/Jbus protocols. It provides two serial interfaces: a dedicated RS232 line for connection to the UPS and a secondary port configurable as RS232 or RS485, allowing integration with management and shutdown software such as PowerShield³ on a connected PC.
Advantages
The MULTICOM-302 supports Modbus/Jbus standards for broad compatibility and reliable data exchange. Dual serial ports give flexibility to connect both the UPS and external devices or networks. Support for RS485 on the secondary port allows longer cable runs and multi-drop topologies, and native compatibility with common management software simplifies monitoring and orderly shutdown procedures.
Suitable for
Integration of Riello UPS systems into building management or SCADA systems
Remote monitoring and control of UPS and transfer switches
Connection to a PC running shutdown and management software such as PowerShield³
Environments requiring RS485 multi-drop or long-distance serial links
Key specifications
Protocols: Modbus / Jbus
Serial ports: 2 (one dedicated RS232 for UPS, second RS232/RS485 configurable)
Compatibility: Works with PowerShield³ and similar UPS management software
Brand: Riello
Manufacturer part number (MPN): MULTICOM-302
How to use
Install the MULTICOM-302 according to the UPS manufacturer’s installation instructions. Connect the dedicated RS232 port to the UPS serial interface, and configure the second port as RS232 or RS485 depending on your network requirements. Attach the other end of the secondary port to a PC running appropriate management software (for example, PowerShield³) or to an RS485 network. Configure communication parameters (baud rate, parity, stop bits, Modbus address) in both the UPS and the management software to match.
Usage recommendations
For reliable operation, use shielded serial cables and proper grounding; keep RS485 cable lengths within recommended limits for your baud rate and use termination resistors where required. Verify firmware and software compatibility with the MULTICOM-302 before deployment.
