1. INTRODUCTION
The nke Box Wi-Fi allows data to be exchanged between the Topline bus and
wireless peripheral equipment such as smartphones, tablets and PCs.
It features a NMEA 183 input to receive AIS data or other data coming from a NMEA
183 compatible instrument and a NMEA 183 output wire.
It works as a multiplexer, combining AIS data with the Topline bus data to send them
over the Wi-Fi link and the NMEA 183 wired output.
New channels can be created on the Topline bus once the NMEA 183 input has been
set up with data coming from auxiliary NMEA 183 sources.
2. NMEA INPUT
The nke Wifi Box can process NMEA data format through the wire input and/or Wifi
wireless connection.
The nke Box Wi-Fi identifies the sentences coming from an AIS receiver or any
NMEA 183 source.
An auto baud rate detection algorithm allows reception of AIS and NMEA data at
4800, 9600, 19200, or 38400 bauds. The baud rate is saved in the memory once 10
correct NMEA sentences have been received.
The AIS data flow received via the NMEA input is sent directly to the Wifi connection
and the NMEA 183 output.
Data coming from the NMEA 183 device is sent once the set up procedure has been
completed on the Topline bus.
WARNING
Topline channels have priority: a NMEA 183 channel is not considered if an
equivalent channel is already available on the Topline bus.
Once the instrument connected to the NMEA 183 input stops transmitting data the
last values are displayed for 64 seconds on the Topline screens.
The NMEA input has priority on the Wifi NMEA connection.
