Varnished / Resined (optionally);
Wide power supply input range: 8…26V AC | 10…40V DC;
Mini-Fit® / AMP SuperSeal 1 5 connectors;
Metal enclosure with fixing lugs;
Possibility to use Metal hose clamps for fixing it without using lugs;
Microprocessor for data control;
Wide temperature range: -40°C / 105°C (-40°F / 221°F)
CONF GURAT ON:
You need Compositor SW67452 software on your PC in order to perform the following:
Define the NMEA 2000 frames received by the converter;
Define the NMEA 2000 frames transmitted by the converter;
Define the Modbus registers readable by the Master;
Define the Modbus registers writeable by the Master;
Update the device

A device’s configuration can also be imported or exported:
To clone the configurations of a programmable “NMEA 2000 / Modbus Slave -
Converter” in order to configure another device in the same manner, it is necessary to
maintain the folder and all its contents;
To clone a project in order to obtain a different version of the project, it is sufficient to
duplicate the project folder with another name and open the new folder with the
button “Open Configuration”

SET COMMUN CAT ON:
This section defines the fundamental communication parameters of two buses, NMEA 2000 and
Modbus
By pressing the “Set Communication” button from the main window for SW67452 (Fig 2) the
window “Set Communication Setting” appears (Fig 3)
The means for the fields for the “NMEA 2000” are:
In the field “Baud Rate” the data rate of the NMEA 2000 is defined;
In the field “TimeOut” the timeout of the data is defined If this time is elapsed the value of
the data of the NMEA 2000 frame become “0” If the “Cancel Data” field is checked in the
“Receive NMEA 2000” window;
The field “Modbus Reg. TimeOut” a Modbus register is defined In this register it is possible
to visualize if the data is reliable, if ‘1’ the data is ok, if ‘0’ the data is oldest of the time
inserted in the “TimeOut Data” field;
If the field “Enable Peer to Peer” is checked, the Source Address of the PGNs received by the
converter is masked (only if a single NMEA device is connected);
In the field “Device D NMEA 2000” the ID of the converter is defined;
If the field “Filter FECA (ms)” is checked, when the FECA PGN arrives the gateway puts the
values in Standby If the time, expressed in milliseconds and written at the right side of “Filter
FECA”, is elapsed and there aren’t arrived the frames of Transport Protocol the gateway put
the data of FECA into Modbus Registers Otherwise if the Transport Protocol arrives before the
time is elapsed the gateway put his data into Modbus Registers discarding the data of FECA
When this field is checked the values aren’t updated when the FECA frame arrive but there is
an offset of xx ms You can use this function if there is only one NMEA 2000 device in the
network
The meaning of the fields of “Modbus Slave” are:
In the field “Baudrate” the data rate of the RS485 bus is defined;
In the field “Parity” the serial parity is defined;
In the field “ D Device” the Modbus ID is defined

RECE VE NMEA 2000:
By pressing the “Receive NMEA 2000” button from the main window of SW67452 (Fig 2) the window “Receive NMEA 2000 Frames”
appears (Fig 4) This section is used to define the NMEA 2000 messages accepted by the converter
The means of the fields of the table are:
In the field “PGN” the PGN of the NMEA 2000 message to receive is defined (in the NMEA 2000 protocol, the PGN is an identifier);
In the field “Source Address” the address of the device that sends the frame is defined
If the field “Transport Protocol” is checked, the frame can use transport protocol functions;
If the field “Fast Packet” is checked, the frame will use the Fast Packet functions;
In the field “Start Byte” the starting byte to save on Modbus side is defined This field is enabled only when the field “Transport
Protocol” is checked;
In the field “Num Bytes” the number of consecutive byte from the starting one is defined For example, if the Start Byte is ‘20’ and
Num Bytes is ‘10’, it is possible to read the byte from 20 to 30;
If the field “Cancel Data” is checked and the “Modbus Register” in the section “Set Communication” is different from ‘0’, the
converter, when the data is oldest of the time inserted in the “TimeOut Data”, sets “0xFF” in the Modbus registers reserved for the
PGN;
If the field “On Request” is checked, the converter sends a request for the PGN: this option is used if the PGN can be only sent on
request by the NMEA 2000 devices;

In the field “List of Modbus Registers Relative to
the PGN Selected” there are the Modbus words
In the field “Create/Modify a Modbus Register”
you can define the index of the Modbus register and
the bytes of the can frame that you map in
For example:
Click on the frame, insert the valid address in the field “Index of
Modbus Register”, select the byte position (Byte 1 in High
Modbus byte and Byte 3 in Low Modbus byte), click the “Create”
button, in the field “List of Modbus Registers” appears the new
Modbus register created with the data that it contains
