User Manual NMEA2000 / Modbus TCP Slave
Document code: MN67225_ENG Revision 1.100 Page 17 of 30
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;
If the field “ Send frame every (ms) ” is checked the gateway sends cyclically the NMEA 2000 frames defined in “Transmit NMEA”
section with the specific delay defined. Otherwise a frame is sent in NMEA 2000 when a modbus register is written into the gateway
(only if “Device till April 2014 (with Jumper)” is selected).
The means for the fields for “Modbus TCP Slave” are:
In the field “ IP Address ”, insert the IP address that you want to give to slave Modbus;
In the field “ SubNet Mask ” insert the SubNet Mask;
In the field “ Gateway ”, insert the default gateway that you want to use. This feature can be enabled or disabled pressing the Check
Box field. This feature is used for going out of the net;
In the field “ Port ” insert the number of the port;
If the field “ Fast StartUp ” is checked, the gateway take less time to go online. This command can use only if the gateway is used in
a 100Mb/s network (only if “Device till April 2014 (with Jumper)” is set);
If the field “ Enable write NMEA on request ” is checked, the field “Write NMEA 2000 frame” in “Transmit NMEA 2000 frame info” is
enabled. If this field is not checked, the device send a NMEA 2000 frame for every written register. Otherwise it is possible to select
when to send the NMEA 2000 frame (only if “Device till April 2014 (with Jumper)” is selected).
