1. PRESENTATION
The NMEA output interface allows the conversion of the Topline data present on the NMEA
data bus, so as to allow the interfacing between your Topline network and the equipment from a
different manufacturer.
When the NMEA output interface is connected to the COM port of a PC with navigation
software, the navigation information (heading and distance to Waypoint, cross-track error) may
be resent from the same COM port on the Topline network via a Gyrographic, a TL25 or an
NMEA input interface.
The NMEA 0183 standard is a specification for communication between items of marine
equipment and GPS equipment. It is defined, and controlled, by the National Marine Electronics
Association (www.nmea.org) .
The 0183 standard uses a simple serial protocol to transmit a “phrase” to one or more listening
units. An NMEA frame uses every ASCII character.
IMPORTANT
-
Read this user guide entirely before starting the installation.
Any electrical connection on the TOPLINE bus must carried out with the terminal box 90-60417. Only use TOPLINE bus cable 20-61-001.
2. INFORMATION CONVERTED BY THE NMEA OUTPUT
INTERFACE
Depending on the sensors connected to the TOPLINE bus, the following information is converted
into NMEA format by the interface:
-
Surface speed, daily log, total log
-
Compass heading, UT time, UT date, depth
-
Water temperature, air temperature
-
Atmospheric pressure
-
Apparent wind speed and angle
-
True wind speed and angle
-
True wind direction
-
Heading and distance to waypoint
-
Cross-track error, bottom speed and heading
-
Latitude and longitude
-
Mast angle
-

LEVEL TROUBLESHOOTING.
This chapter can help you rapidly resolve minor problems which do not require the intervention of
a specialist. Before contacting technical support, please check the troubleshooting table below.
Problem
Possible causes and solutions
The bus cable is not or is badly connected to the terminal box : check the
plugging and the connection inside the terminal box. Check the state of
the cables : they must not show any sign of wear or cut.
The listening apparatus is not properly setup: NMEA 4800 bauds, 8 bits
of data, 1 stop bit.
The listening apparatus does not display the data from the Check that the NMEA frames transmitted by the NMEA output interface
NMEA output interface.
are compatible with the listening apparatus.
You can check the frames using a PC with the NMEA output interface
connected to a COM port and Windows HyperTerminal program (Start
menu/All programs/Accessories/Communications/HyperTerminal). Port
parameters: 4800 bits per second, 8 bits of data, no parity, 1 stop bit, no
flow control.
If you do not manage to solve the problem, please contact your distributor.
