GENERAL WARNINGS
All marine Automatic Identification System (AIS) units utilize a satellite based system such as the Global Positioning Satellite
(GPS) network or the Global Navigation Satellite System (GLONASS) network to determine their position. The accuracy of
these networks is variable and is affected by factors such as the antenna positioning, the number of satellites that are
available to determine a position and how long satellite information has been received for. It is desirable wherever possible
to verify both your vessel’s AIS derived position data and other vessels’ AIS derived position data with visual or radar
based observations.
The compass safe distance of this unit is 0.55m or greater for 0.3° deviation.
In most countries the operation of an AIS unit is included under the vessel’s marine VHF license provisions. The vessel
onto which the AIS unit is to be installed must therefore possess a valid VHF radiotelephone license which lists the AIS
system and the vessel Call Sign and MMSI number. Please contact the relevant authority in your country for more
information.

Safety warnings
This AIS transponder is solely an aid to navigation and can under no circumstances provide complete
and accurate navigation information. AIS is not a replacement for vigilant human lookouts and other
navigation aids such as RADAR. The performance of the transceiver may be seriously impaired if not
installed as instructed in the product manual or due to other factors such as weather and or nearby
transmitting devices. Compatibility with other systems may vary and relies on third party systems
recognising the standard outputs from the transceiver. The manufacturer reserves the right to
update and change these specifications at any time and without notice.
Safety of Life Systems
Nauticast devices may only be used in safety of life devices or systems with the express written
approval of Nauticast. The unsolicited and untested use of Nauticast devices in safety of life devices
or systems may jeopardize the safety or the life of the user or other persons.
Important information for US customers
There are specific laws in the USA regarding the configuration of AIS Class B transceivers.
If you are a US resident and intend to use your AIS Class B transceiver in US waters, you should
make sure that your retailer has configured your product prior to supplying it to you. If your AIS
transceiver has not been pre-configured please contact your dealer for details of how to have it
configured. In the United States the MMSI and static data may only be entered by an
authorized dealer; the end user of the equipment is not authorised to enter or change
their own vessel data.

WHAT IS AIS?
AIS stands for Automatic Identification System. AIS increases the navigational safety and helps
avoid collisions by interchanging vessel identification and route data between nearby ships and land
based stations. This makes identifying ships and their planned course much easier when not in sight
(e.g. at night, in radar blind arcs or shadows or at larger distance).
According to IALA regulations, AIS is defined as follows:
AIS is a broadcast transponder system, operating in the VHF maritime mobile band (using two VHF
channels: 87B - 161.975MHz and 88B - 162.025MHz). It is capable of sending ship information such
as identification, position, course, speed and more, to other ships and to shore. It can handle multiple
reports at rapid update rates and uses Carrier Sense Time Division Multiple Access (CSTDMA)
technology to meet these high broadcast rates and ensure reliable and robust ship to ship operation.
The IMO defines the performance standards as follows:
Ship to ship working, ship to shore working, including long range application, automatic and
continuous operation, provision of information messaging via PC and utilization of maritime VHF
channels .
The Modules:
GPS system, AIS Transponder, VHF Antenna, and the Power Supply (appropriate application
software connects the individual modules).
AIS systems are required to operate in a variety of modes:
The system shall be capable of
 An "autonomous and continuous" mode for operation in all areas. This is the default
mode but can be forced to/from the following alternatives by an entitled authority;
 An "assigned" mode for operation in an area subject to an entitled authority responsible for
traffic monitoring; data transmission interval and/or time slots may be set remotely;
 A "polling or controlled" mode, where data transfer occurs in response to polling from a
ship or entitled authority.
This illustration depicts a typical AIS System where two or more AIS equipped vessels (and shore
based systems) are automatically communicating with each other:
Page 5 of 32
B2 Product Manual 2_0
The illustration below depicts a typical Nauticast B2 installation in a common environment. When
the Nauticast B2 is connected to the vessel’s power supply and both VHF and GPS antenna it fulfils
the requirement for standard operation. The scenario shows a full AIS coverage area (including all
applications and complete shore infrastructure).
1.1
AIS Classes
There are two classes of AIS units fitted to vessels, Class-A and Class-B. In addition to those, AIS
base stations may be employed by the Coastguard, port authorities and other authorized bodies.
AIS units acting as Aids to Navigation (A to N) can also be fitted to fixed and floating navigation
markers such as channel markers and buoys.
Class-A units are a mandatory fit under the safety of life at sea (SOLAS) convention to vessels above
300 gross tons or those that carry more than 11 passengers in international waters. Many other
commercial vessels and some leisure craft are fitted with Class-A units voluntarily. Class-B units are
designed for vessels which do not fall under the mandatory Class-A requirements.
The Nauticast B2 is a fully compliant Class-B AIS unit.

Position Information Source
The marine AIS system uses position information derived from networks such as the Global
Positioning Satellite (GPS) or the Global Navigation Satellite System (GLONASS) in order to determine
the location of the AIS unit and thus the vessel to which it is fitted. The Nauticast B2 utilizes the GPS
satellite network.

Enter your ship’s data
NOTE: To program your Nauticast B2 you will need to connect it to a personal computer or a
notebook with the Link2AIS software installed. There is no external power source needed when
using a USB connection. If you intend to use the optional data cable (product no.: 3001004) on the
vessel, we recommend you still perform the configuration of the Nauticast B2 via USB, in order to
make programming your device easier.
2.4.1
Connecting the Nauticast B2 to your PC
 Connect the Nauticast B2 to your PC/notebook using USB. The LEDs on the device will
first cycle through. Then the PWR LED and the ERR LED will stay on, while the TX LED
flashes. This is the normal sytem behaviour if the device is only connected to the USB
port and no antennas are attached.
Make sure the device is recognized correctly by your PC (Windows shows a message on
the task panel what COM port has been assigned).

of Link2AIS installed not all menu entries shown below may be visible.

Open ‘AIS Settings’ - ‘Identification’. This will display the 'Static Data' for the connected
transponder. This includes the vessel's name, call sign, MMSI number and other fixed
information.

To configure the transponder all of the data fields must be filled and saved.

CAUTION:
For security reasons the MMSI of the vessel cannot be changed by the end user once
they are programmed. Do NOT program the MMSI unless you are certain you have the
correct information. Please check the number entered carefully. If the MMSI is
programmed incorrectly or has to be changed at a later date you have to contact your
supplier or Nauticast GmbH (www.nauticast.com) for a MMSI reset.
Page 10 of 32
B2 Product Manual 2_0
Enter vessel information items in the appropriate boxes:
 MMSI number - enter the vessel's Maritime Mobile Service Identity number (see
warning and further notes regarding MMSI below!)
 Call Sign - enter the vessel's radio call sign (7 characters maximum)
 Ship name - enter the name of the vessel (20 characters maximum)
 Select the most appropriate vessel type from the drop down menu.
 Enter the vessel’s dimensions as follows, rounded to the nearest meter:
o Dimension A - distance from GPS antenna location to bow
o Dimension B - distance from GPS antenna location to stern
o Dimension C - distance from GPS antenna location to max. port
o Dimension D - distance from GPS antenna to max. starboard

CAUTION:
If no valid MMSI is entered (MMSI is pre-set to 000000000) the AIS transponder
will only operate in Receive mode, which means the vessel’s position is NOT
transmitted. As a consequence, the TX LED will remain on (indicating a
transmission error) even when all antennas and main power are connected.
When you have entered all of the vessel's data click the 'Save' button to program this
configuration into the AIS transponder.
A warning will be displayed asking you to verify the MMSI number. The MMSI can only be
changed by your dealer once programmed into the transponder. You can change all other
data (except the MMSI) at any time, should the need arise. Please check the MMSI and if the
number is incorrect, click the 'No' button to cancel programming of the MMSI.
Click the 'Yes' button if the MMSI is correct.
When reopening the ‘Identification’ window you can now see the vessel information stored
on the device. The MMSI number will be displayed with a grey background, to indicate that
it has been programmed and cannot be changed.
You can now disconnect the device from the USB cable / PC and install the hardware on your
vessel. A PC is not necessary for normal operation but can be useful to display all AIS data,
maps and system status. For connecting a Chart Plotter please refer to section 3 “ Connecting

2.5
2.5.1
Installing your Nauticast B2 hardware
Installation hints
We strongly recommend that:
 The GPS antenna is mounted in an elevated position and free of shadow effects from the
ship’s rigg or other super-structure.
 The GPS antenna has a free view through 360 degrees with a vertical angle of 5 to 90 degrees
above the horizon.
 As the received GPS signal is very sensitive to noise and interference generated by other onboard transmitters, ensure that the GPS antenna is placed as far away as possible from radar,
Inmarsat and Iridium transmitters and that the GPS antenna is not mounted within the direct
radar or Inmarsat beams.
 It is also important that the MF/HF and other VHF transmitter antennas are kept as far away
as possible from the GPS antenna. It is good practice never to install a GPS antenna within
a radius of 2 meters from these antennas.
 The VHF antenna should be mounted with at least two meters of vertical separation from
any other VHF antenna, e.g. those used for speech or DCS communication.
 The Nauticast B2 transponder should be mounted on a vertical bulkhead or surface with the
end featuring connectors / cables in the downward position. Use the procided mounting
plate. The mounting location must be protected from weather (e.g. rain, snow, ..) and direct
water spray. The best place, therefore, is at the navigation desk, under the helm station or
some other suitable location in the cabin.
 Safe distance to other electronic equipment should be half a meter.
 The GPS, VHF, power and data cables need to be secured to the bulkhead within 6” to 12”
(15 to 30cm) from the connectors.
CAUTION:
 Use only the parts and cables provided with the Nauticast B2 set or Nauticast accessories to
connect antennas, power and display devices in order to ensure the proper functioning of
the system. When attaching other parts to the system follow the technical recommendations
in section 4.3 “Using different antennas”.
 Do not connect the Nauticast B2 unit to a main line 110/220V AC electrical supply, as it could
cause electric shock or fire. Only use 12-24V DC power sources!
 Do not connect the Nauticast B2 unit to a DC supply exceeding 24V DC or reverse the supply
polarity, because it may cause damage to the unit. Ensure that the power supply is limited
in accordance with EN 60950-1:2006 and protected with a fuse or breakers not exceeding
the specifications listed in this manual.
 The length of either data or power cable must not exceed 3 meters.
 Do not apply excessive force to connectors during installation!
 The Nauticast B2 unit is designed for operation in the temperature range -25 °C to +55 °C.
Do not install (or use) the Nauticast B2 unit in environments which exceed this range.
 Connecting a mismatched VHF antenna, leaving the VHF antenna port disconnected or
shorting the VHF antenna port will activate the VSWR alarm, will cause the unit to stop
sending position reports and can cause damage to the transponder and activate the Error
LED.
2.5.2
Connecting the antennas
Connect the down-lead from the VHF antenna to the VHF antenna port and connect the down-lead
of the GPS antenna to the GPS antenna port. Please see 8.1 APPENDIX A – Block Diagram for proper
antenna installation.
Page 12 of 32
B2 Product Manual 2_0
2.5.3 Connecting Power
Connect the power cable to a 12 VDC or 24 VDC power supply, capable of supplying 2A peak to the
DC power lead (red = positive, black = negative) and plug the power connector into the Nauticast
B2. Please see the Appendix B of this manual for details of the power, data and RF cables supplied.
2.5.4 Mounting the Nauticast B2
Attach the mounting plate with Phillips self tapping head screws (10-32 x 1,2) on a vertical surface.
Please see Appendix C for the mounting plate’s exact dimensions.
Then insert the Nauticast B2 main unit and press down firmly until it snaps in.
2.5.5 Installation Check
You now have successfully completed the installation of your Nauticast B2 AIS system. After
connecting the main power supply allow the system 5 minutes to calibrate and start operation.
Then check the LED status. Normal operation is indicated by:
PWR:

Connecting external equipment
External equipment can be any device complying with NMEA0183 standard or a PC with appropriate
AIS software installed. For information about the data see section 4.2 Data Port Messages (NMEA
0183).
3.1
Connecting to a PC
The connection to a PC can be established either via USB (provides a Virtual Serial Interface) or with
the optional Data Cable (prod. No.: 3001004) and a serial interface (RS232), if the latter is available.
3.2
Connecting to other marine equipment via NMEA0183 (optional data cable
required)
All other devices that support the NMEA0183 standard can be connected with Cable 1 (RS422) of
the optional Data Cable (prod. No.: 3001004). (see Appendix B for more details).
Note: Connections via USB and RS232 use a Baud rate of 115200 by default. If you are
connecting trough RS422 the default Baud rate is 38400. Please make sure to adjust the
port settings on any connected equipment accordingly.
3.3
Connecting an alarm relay (optional data cable required)
An alarm relay (prod. no.: 3001009) can be connected with Cable 3 of the optional Data Cable (prod.
no.: 3001004). (see Appendix B for more details).
3.4
Silent mode (optional data cable required)
By connecting a silent mode switch with Cable 3 of the optional Data Cable (prod. no.: 3001004)
the transmitting function of the Nauticast B2 can be switched off on on. (see Appendix B for more
details).
Note: The TX LED will start flashing when the silent mode is active.
3.5
External LED status indicators (optional data cable required)
If the Nauticast B2 is not visible and the status LEDs should still be monitored, external LEDs can be
connected with Cable 4 of the optional Data Cable (prod. no.: 3001004). (see Appendix B for more
details).
Note: The optional data cable provides the functions on the 4 output cables
simultaneously. Therefore only one cable is needed.

Operation of your Nauticast B2
4.1 Interpreting Status LEDs
Please note that a proper 12 / 24 VDC power suppply is necessary for the B2 to operate flawlessly.
The USB connection will not suffice!
All Class B Devices and hence the Nauticast B2 have a lower priority than Class A devices and base
stations whenever the AIS-channel is highly loaded.
Class B devices send with lower power than class A devices. Therefore a class A device may be
visible to the Nauticast B2, while the reverse may sometimes not be the case.
4.1.1 PWR
A green LED indicates that the unit is connected to an external power source.
NOTE: LED will be a dimmer shade of green on USB power supply as well; however, USB-only
power supply is NOT sufficient for full operation, so make sure 12-24VDC main power is actually
supplied if you want to operate the B2 in normal operational mode (i.e. transmitting AIS data
to other ships)
4.1.2 TX (Timeout)
This LED will show up in amber if the unit has failed to transmit a position report during the last
two reporting intervals.
Reasons for missing reporting intervals might be (examples):
• Message 23 “quiet period”
• A high VDL load
• Positional information unavailable
• Transmissions disabled
• Irregularities in the power supply (USB power alone is insufficient for sending!)
• Connection problems with one of the antennas
• Unit has not been configured
4.1.3 ERR - Error
An amber LED shows up if the unit has failed its integrity test. The unit is equipped with builtin integrity tests (BIIT) which is performed in parallel with standard AIS operation.
The BIIT provide the following test functions:
• Receiver monitoring of background noise level – indicates if background noise level
exceeds -77dBm

CH1 and CH2 – channel information
Two tri-colour LEDs briefly light up (flash), indicating activity of channel 1 and channel 2:
Green flash: channel has received an AIS message
Amber (red and green): channel is transmitting
Red indicates the channel is in DSC mode
Data Port Messages (NMEA 0183)
The data port will output the following:
 Details of relevant AIS transmissions received (VDM messages)
 Details of AIS transmissions sent (VDO messages)
 Details of channel management messages received (VDM messages)
 Alarm messages generated by the BIIT function (ALR messages)
 System notifications generated by the transponder (TXT messages)
 GPS information (RMC, GSA, GSV)
The data port will accept the following inputs:
 Programming information (SSD, proprietary command PNAU)
 Alarm acknowledgements (ACK)
For more information about the interface protocol refer to the latest “PROTOCOL SPECIFICATION”
of the Nauticast B2 or contact our Technical Support Team (see Section: Contact & Support
information).
4.3 Using different antennas
It is possible to use different antennas than the ones provided with the Nauticast B2. For instance,
a combined antenna for VHF and GPS (“combi antenna”) can be used, if there is not enough space
to fit two antennas on the vessel without disturbing other equipment. A combined antenna solution
is available on our website (prod. no.: 1001027 – “AC Marine VHF/GPS-2”).
If other antennas are being used, please take note of the following minimal requierements:
4.3.1 GPS Antenna
The Nauticast B2 has a TNC female bulkhead connector. This port provides a 5V DC feed for an
active GPS antenna, required by the Nauticast B2 unit (i.e. it should incorporate an LNA). Therefore,
the GPS antenna must be an active type using 5V. The antenna must be suitable for marine
applications (index of protection, ruggedness, means of mounting, etc.). An antenna should be
selected with a gain (in dB) depending on the length of cable between the antenna and the AIS unit.
After subtraction of cable and connector losses a minimum total gain of 20 dB should be available
at the Nauticast B2 unit GPS antenna connector. The GPS antenna must be a dedicated antenna,
i.e. not shared with any other GPS receiver. Installation of the GPS antenna is crucial for flawless
operation of the built in GPS receiver, which in turn is used for timing of the transmitted time slots
and for the supply of navigational information.
4.3.2 VHF Antenna
The Nauticast B2 has a UHF female bulkhead connector . The VHF antenna employed for AIS use:
 Must be a dedicated antenna, i.e. not shared with any other VHF transmitter/receiver.
 Must be suitable for marine applications (index of protection, ruggedness, means of
mounting, etc.).
 Should be omni-directional and vertically polarized with unity gain (0 dB) with a bandwidth
sufficient to maintain VSWR <1.5 over the frequency range 156 – 163 MHz. As a minimum
the 3dB bandwidth must cover the two AIS channels and the DSC Channel.
 Should be mounted at least 2 meter apart from any other VHF antenna used for speech or

DCS communication.
4.4

Information Reporting Intervals
The Nauticast Class-B AIS will transmit position reports (Message 18) in reporting intervals of
 Every 30 seconds: if Speed over Ground (SOG) is > 2 kn;
 Every 3 Minutes: if (Speed over Ground) SOG is < 2 kn;
 These transmission intervals will be observed only if the device is connected to 12-24VDC
power supply; the device will not transmit when connected to USB power supply alone!
Transmissions by any class B device, and therefore also the B2, are subject to available time slots
in the broadcast area of the device; e.g. a command received by Message 23 or a large number of
class A devices can override the reporting interval!
Static Data sub messages 24A and 24B will be transmitted every 6 minutes in addition to and
independent of the position report.

ALARM OUT:
If you want to signal an alarm with a LED only, you can connect the LED with a series resistor R
between + (grey) and ALARM OUT (yellow). Depending on the Voltage used for the Nauticast B2
you either have to use a 470(calculated 500) resistor (LED: UF=2V, IF=20mA) when using
12VDC or a 1k (calculated 1100 when using 24VDC.
See calculation in the Section for CABLE 4.
ALARM OUT
How to connect a LED to Alarm OUT
The next figures show the alarm relay (prod. no.: 3001009) and its dimensions, explain how to
connect the alarm relay to the data cable and how to connect the load (alarm circuit) to the alarm
relay. The input voltage of the alarm relay is matched with the operating voltage of the Nauticast
B2. The operating voltage of the alarm relay is 3 to 60 VDC with a load current of 0.1 to 2 A (3A
when using a heat sink).

Connection of the Alarm Relay
CABLE 4:
Depending on the Voltage used for the Nauticast B2 you have to calculate the series resistor which
is connected with the LED between the + wire (grey) and the OUTPUT wire (CH1 LED RED, green;
CH2 LED RED, brown; TX TIMEOUT LED, white; ERROR LED, yellow). A series resistor of 330
(calculated 350) for 12VDC and 910 or 1k (calculated 950) for 24VDC are needed - see
calculation below.
XXX LED
How to connect a LED to XXX LED OUT
Calculation of the series resistor: Used variables
U... operating voltage of the Nauticast B2
UF... Forward Voltage of LED [V]
IF... Forward Current of LED[V]
R... Series Resistor[Ί]
P... Power consumption of the resistor[W]
𝑅=
Examples:
U=12V, UF=2V, IF=20mA:
𝑅=
𝑈−𝑈𝐹
𝐼𝐹
12𝑉 − 2𝑉
10𝑉
= 500𝛺
0.02𝐴
0.02𝐴
As there is already a 150 resistor included for the LED OUT ports, you have to substract this from
the 500. Therefore 350 is the result.
(!) The ALARM OUT has no resistor included therefore 500 is the result. (see CABLE 3)
U=24V, UF=2V, IF=20mA:
𝑅=
24𝑉 − 2𝑉
22𝑉
= 1100𝛺
0.02𝐴
0.02𝐴
As there is already a 150 resistor included for the LED OUT ports, you have to substract this from
the 1100. Therefore 950 is the result. (!) ALARM OUT has no resistor included, therefore the
result is 1100 (see CABLE 3).
