4 INTRODUCTION
Congratulations on the purchase of your Comar i300W NMEA To WiFi Interface.
The i300W NMEA to WiFi Interface provides a low cost method of setting up a wireless network onboard. This will enable you to use marine navigation programs or apps on your smartphone, tablet
or PC to display all your electronic data including position, AIS data, depth, wind, compass heading
and more.
This manual describes the installation and operation of the i300W.
● Before operating the unit you should familiarise yourself with this user manual.
4.1 Parts List
On delivery, carefully inspect the contents of the packing case. Note any damage or any missing
items. Ensure that the correct parts are included for your application.

6 INSTALLATION
6.1 Before you Start
You will need the following items and tools to complete the installation:
● i300W NMEA To WiFi Interface
● Access to 12 V dc or 24 V dc power supply where the unit is to be installed, via a 1 A rated fuse
or circuit breaker / or alternatively a USB cable connected to a USB power source.
● Four screws or other fixings appropriate to the mounting location
6.2 Installing the Unit
The i300W unit is not waterproof and should be installed in a dry location. The unit can be secured
by the 4 mounting holes in the end flanges. It should ideally be installed in a location suitable for
connection to power and NMEA cables, observing a compass safe distance of 0.5 m. When
installing the unit you should consider:
● The best location for WiFi transmission, ideally within sight of the device you wish to connect to
(Mount the device away from obstructions, that can have a negative impact on wireless
performance. Also avoid mounting the unit behind any metal structures.)
● Nearby interference that can impact your i300W Interface installation
● Routing of the power cables to the unit
● Provision of sufficient space behind the unit for cable connections
● Maintaining the compass safe distance of 0.5m
● Visibility of the front panel indicators
6.3 Installation Step 1
● Secure the i300W to a flat surface in the selected location. Use four 5mm wood screws, or other
fixings suited to the material the unit is being fixed to
● The unit may be installed in any orientation
6.4 Installation Step 2
Refer to section 6.5.1 Connection Diagram. Make the electrical connections to the i300W:
● Connect 12 V dc or 24 V dc power supply cables to the power terminals. The positive power
supply wire should be connected to the positive terminal via a 1A rated fuse or circuit breaker.
The negative power supply connection should be connected to the negative terminal. /
Alternatively you can power the device through the USB socket connected to a USB power
source.
● The NMEA-2-WIFI has two NMEA 0183 Inputs, one at 38,400 baud (NMEA IN 1), and one at 4800
(NMEA IN 2) baud.
11
Page 12
i300W
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.

installation and follow the on-screen instructions.
7.3.2 Connecting to your i300W / Read Data
● Before launching the i300W Setup Tool, first connect your i300W to your computer using the USB
cable. After it is connected, you can launch the i300W Setup Tool.
● Select the serial port corresponding to your i300W from the drop down menu at the bottom right
of the i300W Setup Tool window, and click the "Read Data" button.
● The i300W Setup Tool is now communicating with your i300W and will display the current setup of
your device.
7.3.3 Changing the configuration / Write Data

7.4 Factory Reset
To reset the i300W to default factory settings, disconnect all power sources from the unit (power
cables as well as USB cable). Using a paper clip, push the reset button (a click will be felt), power
on the device either through the power connection or the USB cable and hold down the reset
button for at least 5 seconds, after which the factory defaults will be restored.

8 FAULT FINDING
8.1 No green ON LED is displayed
● Check power supply connections and fuse or circuit breaker
● Check polarity of power supply connections
● Check power supply voltage
8.2 No DATA LED flashing
● Check that the NMEA equipment is switched on
● Check polarity of the NMEA cables: A – A (or +), B – B (or -)
8.3 Unable to see the i300W Network
● Move closer to the unit to improve radio reception
8.4 Unable to connect to the unit
● Retry connecting, initially the device may take a while to negotiate with the network, as a radio
device, it is possible to suffer from interference in a busy marina, moving closer to the device will
improve the signal and give a more reliable connection.
