3SETTINGS
The NTWB2 can be used straight out of the box in a typical installation without changing any
settings. The NTWB2 settings can be customised to suit particular user requirements through the use
of DIP switches and WiFi parameters can be customised using an NTWB2 Configuration app.
3.1 DIP Switches
Four DIP switches allow for simple selection of various settings. Refer to Figure 1 - DIP Switches for
their location on the NWTB2.
Figure 1 - DIP Switches
Table 1 below shows the DIP switch functions. The values shown with a grey background are the
switch settings from the factory.
Table 1 –DIP Switch Functions
3.2 NWTB2 Configuration App
An app for Windows PCs and laptops is available for download from the ‘Downloads’ page of
the Madman Marine website www.madmanmarine.com/downloads
The app allows the user to set WiFi parameters such as passwords, IP address, WiFi channel
and SSID. It also provides the ability to monitor the NMEA data being received by the NTWB2.
It is not necessary to use the NTWB2 Configuration app if the NTWB2 is to operate in AP
Mode.
The app must be used to set the SSID and password of an existing WiFi network if the NTWB2
is to be operated in Join Mode. Refer to the NTWB2 Configuration app manual for further
details.

INSTALLATION & USER MANUAL
Page | 7 Rev 1.0
4POWER UP
After connecting power to the NTWB2 the indicator LEDs light up in a specific pattern. Firstly the red
WiFi Status LED turns on for approximately 2 seconds and then the other LEDs turn on and off in the
order of In 1 Data LED, In 2 Data LED and WiFi Data LED. The sequence then reverses after which the
red WiFi Status LED flashes. This indicates a successful power up.
If a WiFi device which has previously connected to the NTWB2 is present then the device may
automatically connect, in which case the red WiFi Status LED will turn off after the NTWB2 has
powered up.
Refer to the Troubleshooting section if any of the LEDs remain on during the power up sequence.
5LED INDICATORS
5.1 Normal Operation
In normal operation, the LEDs behave as per Table 2 below. The NMEA In and WiFi Data LEDs flash
whenever they are receiving valid NMEA data. The rate they flash depends on how much and how
often data is received.

5.2 No Data Received
If no data is being received on any of the NMEA inputs the NMEA In 1, NMEA In 2 and WiFi Data LEDs
will periodically flash in sequence to indicate the fact that the NTWB2 is powered up but no data is
being received.
As soon as data is received on either of the NMEA inputs the LEDs will revert back to normal
operation.
5.3 Turning the LEDs Off
Once proper operation has been confirmed the LEDs can be turned off to avoid being a nuisance,
particularly at night. To turn the LEDs off, move Switch 4 to the OFF position.
When the LEDs have been turned off they will illuminate during NTWB2 power up but will
immediately turn off again once power up has been successfully completed.
The LEDs can be turned on again by moving Switch 4 to the ON position. There is no need to cycle
the power when using Switch 4 to turn the LEDs on or off.

INSTALLATION & USER MANUAL
Rev 1.0 Page | 8
6NMEA OPERATION
6.1 Overview
The NTWB2 can accept two separate wired NMEA0183 inputs and will multiplex the data received
from both inputs to a single WiFi data stream. The NTWB2 can also receive NMEA data from a
connected WiFi device and send that out to a wired NMEA0183 device. Refer to the Installation
section for connection details.
6.2 NMEA Input 1
NMEA Input 1 uses the terminals labelled ‘IN 1’ and is preset to 4800 baud rate. The baud rate for
Input 1 cannot be changed. The orange In 1 Data LED flashes whenever valid data is received.
6.3 NMEA Input 2
NMEA Input 2 uses the terminals labelled ‘IN 2’ and can be set to either 4800 or 38400 baud rate.
Use 4800 for standard NMEA0183 instrument data or 38400 for NMEA HS data such as from AIS
receivers. The orange In 2 Data LED flashes whenever valid data is received.
6.4 NMEA Output
The NMEA Output uses the terminals labelled ‘OUT’ and can be set to either 4800 or 38400 baud
rate. Use 4800 for standard NMEA0183 instrument data (e.g. to an autopilot) or 38400 when that
data rate is supported by the NMEA input of the device connected to the output.
The NTWB2’s output data rate is unrelated to the rate set for Input 2.
7WIFI OPERATION
7.1 Overview
The NTWB2 can operate in two WiFi modes: AP (Access Point) mode or Join Mode. The WiFi mode is
selected using DIP switch 3 (OFF = AP Mode, ON = Join Mode).
Select AP Mode (Figure 2) when no other WiFi router is present and you want to have other
WiFi devices (phones, tablets, PCs etc.) connect to the NTWB2’s WiFi network.
Select Join Mode (Error! Reference source not found.) when you want the NTWB2 to c
onnect to an existing WiFi network such as that of an existing WiFi router on your boat.
The NTWB2 is configured to work in AP Mode out of the box without any further configuration or set
up.
7.2 Devices and TCP/UDP Connections
Up to 7 WiFi devices can connect to the NTWB2 simultaneously, although only one of them can
establish a TCP connection at any one time. It is therefore best to have the main WiFi device to be
used set to TCP with any other devices to be connected set to UDP.
Note: Attempting to make more than one simultaneous TCP connection will cause improper
operation.

Figure 2 - NTWB2 AP Mode Diagram
7.3 AP (Access Point) Mode
7.3.1 Overview
In AP Mode, the NTWB2 creates a WiFi network for up to 7 other WiFi devices to connect to.
Note: DIP Switch 3 must be set to the OFF position to use AP Mode.
7.3.2 Default AP Mode WiFi Settings
Unless changed with the NWTB2 Configuration app, the NWTB2’s WiFi settings are as follows…
SSID: Madman xxxx (where xxxx are alphanumeric characters, 0-9 and A-F).
The AP Mode SSID is factory set and cannot be changed.
Password: A unique AP Mode password is factory set for each NTWB2.
The AP Mode password can be changed using the NTWB2 Configuration app.
IP Address: The NTWB2’s default IP address is 169.254.2.1
The AP Mode IP address can be changed using the NTWB2 Configuration app.
Port: The NTWB2’s default port is 55555
The AP Mode port can be changed using the NTWB2 Configuration app.
7.3.3 Connecting WiFi Devices in AP Mode
After successful power up in AP mode the NTWB2 will be broadcasting its WiFi network SSID and the
red WiFi Status LED will be flashing.
To connect a WiFi device such as a phone, tablet or PC, look for the NTWB2’s SSID (Madman xxxx) in
the list of available WiFi networks in your device’s WiFi settings. Select the NTWB2 network and
enter the NTWB2’s AP mode password.
Once at least one WiFi device is connected to the NTWB2’s WiFi network then the red WiFi Status
LED will turn off.
NMEA data being sent to the NTWB2 will now be available at the connected WiFi device.

7.4 Join Mode
7.4.1 Overview
In Join Mode the NTWB2 does not create a WiFi network. Instead the NTWB2 attempts to connect to
an existing WiFi network according to the Join Mode SSID and password that has been set.
Note: DIP Switch 3 must be set to the ON position to use Join Mode.
7.4.2 Default Join Mode WiFi Settings
Unless changed with the NWTB2 Configuration app, the NWTB2’s WiFi settings are as follows…
SSID: No default SSID is set.
Use the NTWB2 Configuration app to set the SSID of the network to join.
Password: No default password is set.
Use the NTWB2 Configuration app to set the password of the network to join.
IP Address: No default IP address is set.

8INSTALLATION
8.1 Overview
The NTWB2 must be installed in a location that is clean, dry and not subject to high humidity or
extremes of temperature. For optimum performance it should be located such that there are as few
obstructions as possible between it and the WiFi devices to which it will communicate.
All electrical connections are made using the green plug-in connector supplied. The electrical
connections can be made with or without the plug-in connector plugged in to the NTWB2.
The terminals are of the spring type for superior resistance to vibration and no tools are needed to
connect pre-stripped wires.
The terminals also have test probe insertion holes (1mm diameter) to facilitate testing when plugged
in. Refer to Figure 5 for details of the green plug-in connector.
8.2 Making Connections
The spring terminals of the plug-in connector will accept wires up to 0.5mm2(20 AWG). The wires
must be stripped back 8mm (5/16”) and the strands either lightly twisted or crimped in a 0.5mm2
ferrule.
Figure 4 - Wire Strip Length
Using your fingernail or a small screwdriver, depress the orange button and insert the wire all the
way into the terminal below the orange button. Release the orange button and gently pull on the
wire to ensure it is held in place by the terminal.

8.3 Terminal Designations
Refer to Table 3 below for the terminal designations.
Table 3 - Terminal Designations
8.4 12V Supply Wiring
The NTWB2 requires a fused 12V supply to be provided to it in order to operate. An internal,
automatically resetting fuse protects the NTWB2 but an external fuse or circuit breaker must be
provided to protect the wiring to the NTWB2.
Connect +12V to either of the terminals labelled ’12 V’. The 12V supply should be provided from a
switch or circuit breaker to switch it off the NTWB2 when it is not needed and also to enable
isolation when wiring. There is no on/off switch on the NTWB2 itself, however the NTWB2 can be
disconnected by removing the green plug-in connector.
The NTWB2 has a second set of +12V terminal and 0V terminals which allows for 12V supply wiring
to a second device. The terminals are connected internally and so the connector must be plugged
into the NTWB2 for the 12V supply to be present on the second set of terminals.
Note: the internal fuse only protects the NTWB2 and does not protect any other devices connected to
the green connector!
