NMEA4WIFI - A MULTIPLEXER AND A TOOL

THE MULTIPLEXER allows bidirectional serial and wifi communication between your smart-phone, tablet or laptop and your boat instrumentation. The Nmea4Wifi multiplexer can be simply configured using a Web Browser. It has four opto-isolated Nmea 0183 input ports and one Nmea 0183 output port. The multiplexer also has an input/output USB port. One of the 4 input ports can be configured to receive SeaTalk1 data which will be converted to Nmea 0183 data. Wifi communication can use both the UDP and the TCP internet protocols. In total there can exist 6 input streams of data (4 serial, 1 UDP and 1 TCP) and 3 output streams of data (1 serial, 1 UDP and 1 TCP). The 6 input streams can be filtered, combined and transmitted to the receivers on any of the 3 output streams. Serial output can also be filtered. You can use this multiplexer in different ways. You can use it with a PC running navigation software such as OpenCPN or you can use it with several free Apps for Android or Ios. In addition you can get Sonar Chart Live maps on your Navionics Boating HD app.


THE TOOL is a windows programme, hereby referred to as the Nmea4Wifi tool, to help in the configuration of the Nmea4Wifi multiplexer. The configuration of the Nmea4Wifi multiplexer can be totally done with a simple Web Browser, either in a PC or in a smartphone, without the need of the present Nmea4Wifi tool. However, the tool is particularly useful if you need to set complex Nmea 0183 sentence filtering or if you need to update the multiplexer firmware without using a USB cable. The tool is also capable of transmitting and/or recording Nmea 0183 sentences for testing purposes. The present Help File contains information on how to use the Nmea4Wifi multiplexer as well as information about the Nmea4Wifi tool.
