Multicom 302

Technical Specifications - MultiCom 302 Protocol Converter
Overview

• Protocol converter card for Riello UPS and Transfer Switches.
  
• Enables monitoring and control via Modbus (RTU) / Jbus and proprietary protocols.
  
• Provides two serial communication ports:
  • SERIAL 1: RS232 (for proprietary GPSER protocol)
  • SERIAL 2: RS485 Half-Duplex or RS232 (Modbus/Jbus or GPSER)

Communication Features

• Baud Rate Support: 1200-57600 bps (configurable via DIP switch or MultiSetup software).
  
• Parity Options: None, Even, Odd.
  
• Stop Bits: 1 or 2.
  
• LEDs indicate serial activity (Green for SERIAL 1, Yellow for SERIAL 2).
  
• Supports Modbus function codes:
  
  • 0x01, 0x02 (Bit Reading)
    
  • 0x03, 0x04 (Register Reading)
    
  • 0x06, 0x10 (Register Writing)

Installation & Configuration

• Plug into UPS communication slot (hot-swappable).
  
• DIP switches available for setting:
  • RS232/RS485 mode
    
  • Device Modbus address (1-31 via DIP, 32+ via software)
    
  • Baud rate
    
  • RS485 bus terminal resistor (120Ω option)

Monitoring Capabilities

• Real-time UPS status, measurements (e.g., voltages, frequencies, load percentages, battery data).
  
• Alarm monitoring (e.g., low battery, overload, UPS failure).
  
• Commands support for shutdown, battery testing, and diagnostics.

Environmental

• Indoor installation only (clean, dry environment).
  
• Operating Temperature: 0°C to 40°C.
  
• Relative Humidity: <90% RH (non-condensing).
