The 38,400 baud NMEA data input (NMEA IN 1) would normally be connected to an external AIS
Receiver or Transponder, however it will also accept any other NMEA data at 38,400.
Any 4800 baud NMEA data such as from a GPS, Chart Plotter or Instruments can be connected
to the NMEA IN 2 terminals, observing the correct polarity. The unit can only be connected to one
piece of equipment so choose the unit that has the most information that you require. If you have
several pieces of equipment that you wish to receive data from then you may need to purchase
a NMEA Multiplexer to combine all this data into one before connecting to the WiFi unit.
If the equipment that you are connecting to has a pair of NMEA cables, normally marked NMEA
Output Positive (A) and Negative (B) these should go to the respective NMEA input on the WiFi
unit.
If the equipment has only one Positive NMEA output wire this should go to the A NMEA Input and
a wire from the B NMEA Input should then be taken to the common ground/negative of the other
equipment.
Connect a NMEA 0183 AIS source to the “NMEA IN 1” input..
6.5 Installation Step 3
Apply power and verify that the unit is operating:
●
Apply power to the i300W and all connected devices.
● Verify that the green power LED on the i300W is illuminated
●
Use a WiFi enabled device like a smartphone, tablet or PC and search for WiFi networks. Your
device should find the i300W network and you should be able to connect without a password.
●
Wait for the connected AIS receiver to receive the first AIS messages (usually indicated by flashing
LEDs). Once the AIS receiver is sending NMEA 0183 AIS data to the i300W you should see the
indicator LED “NMEA IN 1” flashing yellow.
●
Now, open a marine navigation program / app that is able to process AIS messages on your WiFi
enabled device that you have connected to the i300W WiFi network. In the settings page of the
program / app set the AIS settings as follows:
Protocol: TCP
IP Address: 10.10.100.110
Port: 10110
Once sucessfully connected you should see the AIS data displayed on your screen.
