3. NMEA Flash Input Interface


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, pilot, calculator.

The NMEA input interface allows the connection of a 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.
