  • Page 4: Introduction

    INTRODUCTION The Oceanic Systems’ NMEA2000 to Modbus Gateway (Part No 3155) makes NMEA2000 messages from Engine, Generators, Tanks, Batteries, AC Sources and Switch Banks available over a Modbus interface to PLC based vessel monitoring systems. This unit is designed to operate in a protected marine environment such as an engine room or below decks.

    INSTALLATION 2.1 UNPACKING THE BOX You will find the following items in the 3155 shipping box: 1 x 3155 NMEA2000 to Modbus Gateway 1 x 3155 User Manual (This document) 2.2 CHOOSING THE MOUNTING LOCATION 1. The unit is designed to be mounted on a DIN rail in an electrical cabinet with free air circulation in a dry location below decks.

  • Page 6: Connecting The Rs485 Modbus Interface

    2.4 CONNECTING THE RS485 MODBUS INTERFACE 1. The RS485 Modbus cable should be connected to the terminal block on the lower edge of the 3155 unit. Tighten the terminal block screws to grip the cable securely ensuring that a sound electrical connection has been made. C O M Fig.3 RS485 Connections The RS458 Modbus Interface wires are connected as follows:...

  • Page 7: Configuration

    CONFIGURATION 3.1 MODBUS COMMUNICATION PARAMETERS The 3155 NMEA2000 to Modbus Gateway Modbus interface communications parameters are by default set to 19,200 Baud, EVEN parity, 1 stop bit ex factory The RS485 communications parameters can be changed at any time by setting the ADDR switch to the following number and pressing the COM push button with power on according to the following table: ADDR switch position...

  • Page 8: Modbus Slave Address

    3.2 MODBUS SLAVE ADDRESS • A single Modbus network may have a number of slave units attached and these units MUST have each a unique slave address. • The 3155 NMEA2000 to Modbus Gateway Slave Address can be set from 16 decimal to 1 decimal by using the small rotary switch on the front panel labeled “Addr”...

    FRONT PANEL INDICATORS AND SWITCHES The front panel has the following LEDs: LED Name Description NMRx Receiving an NMEA2000® message NMTx Transmitting an NMEA2000® message MoRx Receiving a Modbus message MoTx Transmitting a Modbus message MoFlt Invalid Modbus message CmFlt Communications error PGN became Data Not Available DefCm...

  • Page 10: Fault Finding/Troubleshooting

    FAULT FINDING/TROUBLESHOOTING The front panel indicators should be used to assist in fault finding as follows: 5.1 COMMUNICATIONS ERROR LEDs If the CmFlt led is lit this means that the unit detected an error in the communications param- eters being used on the Modbus interface. Please check that the transmission protocol EXACTLY matches the Modbus Communications Parameters in section 3.1 above.
