1 PRESENTATION
The NMEA input interface allows the connection to the Topline bus of any instrument fitted
with an NMEA 0183 output (GPS, PC, etc.). It is a one-way communication gateway, which
converts the NMEA data transmitted by the instrument, into Topline channels. These can then
be used on the instruments of your Topline installation : display, driver, calculator.
The NMEA input interface allows the connection of one single instrument that delivers NMEA
frames. If you wish to connect a second instrument, you can connect it either to the NMEA input
of a TOPLINE multifunction system, or to a second NMEA input interface.
Please note that an NMEA frame transmitted by an instrument (GPS, PC, etc.) cannot replace
a channel already created by a Topline instrument of your installation.
IMPORTANT
-Please read this guide completely before starting the installation.
- Any electrical connection on the TOPLINE bus must carried out with the terminal box 90-60-
121. Only use TOPLINE bus cable 20-61-001.
2 LIST OF IDENTIFIED NMEA FRAMES
The NMEA input interface identifies the frames below. The interface is thus able to create up
to 40 NMEA channels on the Topline bus of your installation. These NMEA channels do not
have sub-channels.
Please note :
- Topline channels have priority : an NMEA channel will not be taken into account if an
equivalent Topline channel is already present on the bus.
- When the instrument connected to the NMEA input interface no longer transmits NMEA
frames, the last values received remain on display for 64 seconds.

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 Topline installation does not detect the NMEA
Interface. The NMEA frames do not show on the Topline
display of your installation.
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.
Have you initialised the NMEA interface ? After initialisation, the
red initialisation wire must be connected to the earth or to the init
terminal : see installation chapter
An NMEA channel does not show on the Topline display
of your installation. The Topline channel is already present and provided by an nke instrument.
If you do not manage to solve the problem, please contact your distributor.

5.1 List of accessories
-TOPLINE terminal box : 90-60-121
-TOPLINE terminal box, with NMEA connection : 90-60-417
5.2 Installation precautions
The housing of the NMEA input interface is waterproof against water spray. Install the housing
in a location that is unlikely to get flooded.
5.3 Installation of the NMEA input interface housing
-Fix the housing in place using Ø4 screws
CAUTION :
-The connection of this sensor must be carried out with the power switched off.

5.4 Connection to the Topline bus
1. Make the bus cable run from the NMEA input interface to the TOPLINE terminal box of
your installation.
2. Connect the bus cable inside the terminal box.
3. Connect the NMEA+and NMEA-conductors to your instrument.
If you reduce the length of the bus cable, strip and galvanise the wires before connecting them
inside the terminal box.

5.5 Initialisation of the NMEA input interface
At the first power-up, the NMEA input interface must be initialised in order to identify and
memorise the NMEA frames transmitted by the instrument (GPS, PC, etc.). The NMEA
channels created are then saved to the memory of the NMEA input interface, and restored at
each power-up, on the Topline bus.
5.5.1 Initialisation procedure
-Disconnect the red wire from the init terminal (or from the GND terminal).
-The NMEA input interface then performs a search sequence of NMEA data as long as the
red initialisation wire is disconnected, then it creates the new channels that correspond to
the NMEA frames transmitted by the instrument. A sounding beep is emitted for each NMEA
frame identified.
-Reconnect the red initialisation wire to the init terminal (or to the GND terminal).
Initialisation is then complete and you may select the NMEA channels on the Topline
Multifunction displays of your installation.
Please note that this initialisation procedure can be repeated at any time, to start over a failed
frame identification for example.
CAUTION :
- Under normal operation, the red wire must remain connected to the init terminal (or to the
GND terminal).
- Use one NMEA input interface per instrument that transmits NMEA frames ; Each interface
will thus be initialised separately.
