SET COMMUNICATION:

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.
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
converter is masked (only if a single NMEA device is connected);
In the field "Device ID NMEA
If the field "Filter FECA
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 "ID Device" the Modbus ID is defined.
