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.
