3 of 59
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. It is very important that it is installed and set up correctly according to this
manual. Please read and follow the installation and setup instructions carefully to achieve the
best results.
1.1 PRODUCT FEATURES
The 3155 NMEA2000 to Modbus Gateway has the following features:
• RS485 Modbus Interface RTU protocol
• NMEA2000 Interface
• DIN Rail mount enclosure
• Passes NMEA2000 messages from Engines, Generators, Batteries, AC Sources, Fuel Tanks,
Fresh Water Tanks, Grey Water Tanks, Black Water Tanks and Oil Tanks to the Modbus
Interface
• Has easy communications setup controls for the RS485 Interface
• Status and Warning lights for all data transfers
• Allows monitoring and Control of 8 switch banks of 28 switches (224 in total)

2.1 UNPACKING THE BOX
You will nd 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.
2. The cabinet may be located in an engine room providing the ambient temperature
does not exceed 50⁰C (125⁰F).
3. The location needs to allow for connection to the NMEA2000® interface cable and
the RS485 Modbus cable.
2.3 MOUNTING THE UNIT
1. The unit should be hooked over the top of the DIN rail and then pushed back into
location until the red tab at the bottom of the rear of the unit snaps behind the
lower edge of the DIN rail. (Fig.1)
2. The unit can be dismounted from the DIN rail by using a screwdriver to release the
red tab whilst lifting the unit upwards from the mounting rail. (Fig.2)
Fig.1 Fig.2

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.
The RS458 Modbus Interface wires are connected as follows:
2.5 CONNECTING THE NMEA2000® INTERFACE
1. The NMEA2000® interface cable on the unit should be connected to a nearby
NMEA2000® Tee connector (part number 3802).
2. The male end of the cable should be inserted into the female Tee connection
noting the position of the keyway in the plug and the socket.
3. The unit can be connected with power on or off without any damage.
4. Ensure that the locking ring is securely tightened so that
the connection remains sound.

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:
Please note that if the chosen communications parameters are NOT set to the default then the
DefCm green led will NOT be illuminated.
The unit can be reset to the default values at any time by pressing the Set DefCom push button
when the unit has power on and the ADDR switch is set to “0”. When they are set to the default
value the DefCm green LED is illuminated.
ADDR switch position Communications Parameters
019,200 Baud, Even Parity, 1 stop bit (Default)
1 19,200 Baud, Odd Parity, 1 stop bit
2 19,200 Baud, No Parity, 2 stop bits
3 9,600 Baud, Even Parity, 1 stop bit
4 9,600 Baud, Odd Parity, 1 stop bit
5 9,600 Baud, No Parity, 2 stop bits
6 4,800 Baud, Even Parity, 1 stop bit
74,800 Baud, Odd Parity, 1 stop bit
84,800 Baud, No Parity, 2 stop bits

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” as
per the following table:
3.3 MODBUS TERMINATION RESISTOR
Please note that this unit does NOT include any Modbus network termination resistor as the
master normally includes this. If this is not the case then a RS485 termination resistor MUST be
included in the Modbus Communication line
3.4 NMEA DEVICE INSTANCE
NMEA2000 requires a unique Device Instance for each 3155 NMEA2000 to Modbus Gateway on
a single network. This is settable from device instance 0 to Device Instance 15 using the lower
small rotary switch on the front panel labeled “Addr”. This can be set at any time regardless if
power is on or off. The switch counts from 0 – 9 then A – F being equivalent to Device Instance
0 – 15.
Please note that this switch also controls the Modbus Slave Address so a compromise address
that suits both interfaces should be chosen.

4FRONT PANEL INDICATORS AND SWITCHES
8 of 59
The front panel has the following LEDs:
The rotary switch is used to set the communications protocol, the Modbus Slave Device Address
and the NMEA2000 Instance. See 3.1 To 3.3 above
The pushbutton is used to capture the default communications protocol from the rotary switch.
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 Default Communications Protocol in use

FAULT FINDING/TROUBLESHOOTING
5
9 of 59
The front panel indicators should be used to assist in fault nding 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.
5.2 INVALID MODBUS MESSAGE ERROR LED
If the MoFlt led is lit this means that the unit received a Modbus message that it could not carry
out. This indicates that the communications protocol is probably correct but that the message
content was invalid. This could be either the wrong Modbus command or wrong data length
request.
5.3 UNMARKED LED – PGN BECAME DATA NOT AVAILABLE
This green led comes on if any PGN that has been received is not received for a period of great-
er than 10 seconds. This led will stay illuminated until the next power ff poer on cycle occurs.
This can indicate a failing or removed NMEA2000 device on the bus.

DATA NAMING CONVENTION
6
10 of 59
Because it is easy to misunderstand base numbering system it is being shown in this document
decimal / base 10 values are shown thus:-
10 = decimal value of ten
Hexadecimal / base 16 values are shown thus:-
0x10 = decimal value of sixteen.

MODBUS DATA REGISTERS
7
11 of 59
The unit can receive NMEA2000 information from
• 3 Engines
• 8 Fuel Tanks
• 8 Fresh Water Tanks
• 8 Grey Water Tanks
• 8 Black Water Tanks
• 8 Oil Tanks
• 3 Generators
• 3 AC Sources
• 8 Battery Banks
• 4 Battery Chargers
• 8 Banks each of up to 28 switches (224 switches)
The unit can also control the 8 banks of 28 switches individually or collectively
Read access to all registers can only be made using the Modbus Function Code 04 Read
Input Register command.
There is NO write access to any input registers except the Switch Bank Registers.
Note that if a NMEA2000 PGN is not available then the data elds will always read
0xFF which is the standard NMEA2000 value for “Data Not Available”
The information from the NMEA2000 connected devices is stored in 16 bit Input Registers
that can be accessed from the Modbus Interface according to the following tables:
