Adding NMEA Data from External Devices
You can display on Scala data received from external devices such as GPS, sonar, winch control
system, compass or anemometer.
Before you begin
• Check the equipment from which you want to receive data to help you complete the parameters.
• Check that your version of Scala is able to read information sent by the device: see Compatible
Incoming NMEA Sentences on page 131.
Procedure
1.
Click Menu > Settings.
2.
Under the NMEA Inputs tab, click Add.
3.
Choose the type of connection between serial port, UDP or TCP socket.
4.
If using a serial port:
a)
In Port, select the incoming data you want to add.
b)
In Baud, choose the transmission speed (bit per second).
c)
Leave the other default parameters if you have no specific requirements.
d)
Select a different input format if you have Marelec or Rapp Marine/Rapp Hydema equipment.
Otherwise, select Standard NMEA format.
e)
To broadcast the data received on this serial port to other equipment than Scala, select
Output to UDP, then enter a port above 1000 and enter 255.255.255.255 to broadcast to all
equipments, or enter a different subnet mask.
5.
If using UDP:
a)
enter the port of the server sending data.
6.
If using TCP:
a)
Enter the IP address of the server and the port.
b)
Select a different input format if you have Marelec or Rapp Marine/Rapp Hydema equipment.
Otherwise, select Standard NMEA format.
7.
Click OK.
Note: Minimum data requirements to have trawl positioning are: heading, GPS position,
warp length and relative bearing angles from door positioning sensors.
Results
In the control panels, new data appears under Sensors Data > NMEA.
