1.4 Important Information
1.4.1 Network Security
The NTWB1 cre tes n open network with no p ssword required to
connect to it. Do not connect WiFi device (such s pc) which h s
sensitive inform tion stored on it s nyone within close proximity could
potenti lly connect to the NTWB1 nd ccess the connected device(s).
If it is necess ry to connect device with sensitive inform tion stored on
it then seek profession l dvice on how to protect your device. As
minimum, ensure ll virus detection nd firew ll softw re is up to d te
nd oper ting.
If you re r cing your competitors could potenti lly view your bo t's
instrument d t when in r nge of the NTWB1's WiFi sign l due to the
open network. Ple se be r this in mind when r cing!
1.4.2 Discl imer
Use the NTWB1 entirely t your own risk. M dm n M rine Pty Ltd
will not be held li ble for ny consequenti l loss, d m ge or injury in ny
w y connected with the use of the NTWB1 NMEA to WiFi Bridge.
M dm n M rine Pty Ltd’s li bility under ny circumst nces sh ll not be
gre ter th n the origin l purch se price of the NTWB1.

2.1 Installation
2.1.1 Overview
The NTWB1 c n be mounted to ny fl t surf ce inside the bo t’s c bin
where it will be protected from w ter nd mech nic l d m ge.
The NTWB1 does not need to be in direct line of sight of the WiFi devices
which will connect to it so c n be hidden out of view if desired, however
the fewer obstructions between the NTWB1 nd connected WiFi devices
the better the reception perform nce will be.
2.1.2 Mounting Loc tion
The following must be t ken into ccount when selecting
mounting loc tion:
•Room to tt ch the ntenn ,
•Ability to view the LED indic tors,
•Obstructions between NTWB1 nd other WiFi devices,
•Protection from w ter (including condens tion) nd mech nic l
d m ge,
•Proximity to equipment or c bling which could c use interference to
or be interfered by the NTWB1.
There re two fl nges on the NTWB1 enclosure which h ve holes
provided for mounting to ny fl t surf ce with screws (2 required).
Altern tively self- dhesive Velcro could be used to mount the NTWB1 in
ny convenient loc tion. Refer to Illustr tion 2 for fl nge loc tions.

2.2.1 C ble Route Consider tions
Although the supplied c ble h s individu lly screened conductors to
reduce the effects of interference from electrom gnetic noise (EMI) c re
should still be t ken in selecting the route the c ble of the NTWB1 is to
t ke. The c ble should be kept s f r s possible from the following items:
•r dio tr nsmitters,
•ntenn s nd ntenn c bles,
•fluorescent lights,
•electric l c bles c rrying AC current,
•engines including outbo rd motors
•AC powered electric l equipment

Also void routing the c ble ne r comp sses or other sensitive
instruments to void interference from the NTWB1.
2.2.2 Electric l Colour Code
The colour coding of the 4 cores of the NTWB1 c ble is s follows:
Red +12Vdc
Black 0Vdc
Yello NMEA d t OUT (to Listeners)
White NMEA d t IN (from T lker)
2.2.3 Electric l Connections
Connect +12V to the red wire nd 0V (neg tive) to the bl ck wire. If you
in dvertently reverse the pol rity no d m ge will be done to the NTWB1.
Simply reconnect with the correct pol rity.
The White wire c rries d t to the NTWB1 from NMEA t lker. The Yellow
wire c rries NMEA d t from the NTWB1 to NMEA listeners.
The NMEA connections re single-ended where the 'other side' is
connected to 0V. This me ns where two wires (A/+ & B/-) re provided on
your NMEA equipment for NMEA In only one wire (the A/+ wire) need be
connected. This pplies for the NMEA Out wires lso.
Refer to the specific instructions for the p rticul r NMEA equipment you
pl n to connect for sign l wire colours s the wire colours re not
st nd rdised between m nuf cturers.
Note: The B/- wires ay need to be connected to 0V (negative) if the
single wire connection does not work. Refer to anufacturers instructions
to check if this can be done without da aging the equip ent.

3.1 Operation
3.1.1 Initi l Steps
1. Ensure ll electric l connections h ve been m de correctly.
2. Screw the ntenn on to the ntenn socket if not lre dy inst lled.
3. Turn on the 12V supply to the NTWB1
4. Check th t the LED indic tors re fl shing green nd red. (If NMEA
d t is v il ble the or nge LED will fl sh lso).
3.1.2 Connecting WiFi Device
1. N vig te to the WiFi settings on the device you wish to connect to
the NTWB1.
2. Look for the 'M dm n xxxx' SSID (where xxxx is a ix of nu bers and /or
letters) in the list of v il ble WiFi networks. See left i age of
Illustration 3 for iPhone exa ple.
3. Select the Mad an xxxx network and wait for your device to
establish a WiFi connection. No password is required. See right i age
of Illustration 3 for iPhone exa ple.
4. When your WiFi device has connected to the NTWB1 the red LED will stop
flashing and will re ain off
3.1.3 Configuring Softw re
Refer to your pp's or softw re's document tion for guid nce on
configur tion to est blish TCP or UDP connection.
Gener lly, the three things to be configured re the protocol (TCP or UDP),
the IP ddress of the source of the d t (169.254.1.1) nd the port
(55555).

3.1.6 Indic tor Lights
There re three different light colours which the NTWB1 uses to present
st tus inform tion. All lights ct independently of e ch other.
Light State Meaning
Red Off A WiFi device h s connected
since power on
Fl shing No WiFi device h s
connected since power on
Green Slow Fl shing No TCP connection (UDP
connections m y be in
progress)
On A TCP connection is in
progress
Or nge Off No NMEA d t being
received.
Fl shing NMEA d t being received
On Continuous NMEA d t
being received.
Red, Green, Or nge Off NTWB1 is off (no power
being supplied to it) or sleep
mode ctive.

Chapter 3
Operation
3.1.7 Sleep Mode (Power S ving) nd Autom tic W ke Up
The NTWB1 will enter sleep mode to s ve power if no NMEA d t h s
been received for 60 seconds. It will utom tic lly w ke up every 5
minutes or whenever NMEA d t is being received.
The NTWB1 will st y w ke whenever NMEA d t is being received
periodic lly with no more th n 60 seconds between d t gr ms.
While in sleep mode, ll lights rem in off, the WiFi r dio is turned off nd
only sm ll mount of power will be consumed. Bec use the WiFi r dio is
off the 'M dm n xxxx' SSID will not be found.
To w ke the NTWB1 from sleep mode do one of the following:
•Send NMEA d t to it (vi the wired NMEA connection)
•W it 5 minutes t which time it will utom tic lly w ke up
•Cycle the power to it.
3.1.8 About UDP nd TCP – Which Do I Choose?
Very b sic lly, TCP is reli ble protocol in th t the d t is gu r nteed to
be received due to two-w y h ndsh king between sender nd receiver
where s UDP is unreli ble in th t the sender h s no w y to know whether
the UDP d t w s received ( nd doesn't c re either). For displ ying
m rine instrument d t for inform tion only, UDP is more th n suit ble s
the d t is regul rly upd ted so if some UDP d t is not received t one
moment it is quickly repl ced by new d t soon fter.
The NTWB1 c n only m ke one TCP connection t time but c n m ke up
to seven UDP connections, so select TCP if you re using only one device
nd UDP if you need to connect sever l devices.

3.1.9 NTWB1 Connections & NMEA Repe ters
The NTWB1 c n m ke simult neous TCP nd UDP connections but only
the TCP connected device will receive d t from the NMEA connection of
the NTWB1.
However, d t from other devices c n be simult neously p ssed to other
devices connected to the NTWB1 vi UDP while the TCP connection is
ctive. This me ns if you h ve device running softw re which c n ct s
n NMEA repe ter such s OpenCPN running on PC, you c n h ve TCP
connection for the NMEA d t from the NTWB1 to OpenCPN nd then re-
bro dc st the NMEA d t vi UDP to the other devices connected to the
NTWB1. In OpenCPN, cre te sep r te 'output' network connection with
IP ddress of 169.254.1.255, UDP protocol nd port number in the r nge
49152 to 65535 The other WiFi devices will need to listen to the port set
in the new output connection of OpenCPN with UDP protocol nd IP
ddress 169.254.1.1
