2 Operation General Introduction
Thank you for purchasing the Simrad AIS Class A transponder.
The Simrad MX535B has been developed to offer you the highest level of performance and durability and we
hope that it will provide many years of reliable service. This product has been designed to meet the highest
possible quality standards and should you encounter any problems with this product, please contact your
local dealer for assistance.
2.1 About AIS in general
The Automatic Identification System (AIS) is based on the IMO regulation for AIS using Self Organized Time
Division Multiple Access (SOTDMA) technology based on a VHF Data Link (VDL).
The system operates in the following modes:
O Autonomous (continuous operation in all areas)
o Assigned (data transmission interval remotely controlled by authority in traffic monitoring
service)
o Polled (in response to interrogation from a ship or authority)
o Silent (listening only, use with caution)
The system is synchronized with GPS time (UTC) to avoid conflict among multiple users. If GPS data is
not available, the system is self-synchronized using the VDL message.
The VHF channels 2087 and 2088 are the main AIS channels in addition to local AIS frequencies. AIS
transponders onboard ships exchange various data as specified by IMO and ITU on either frequency
set up by:
O The frequency management telecommand (DSC)
O Special AIS messages sent from an AIS Base station
O Manual input of special region
The normal transmit power is 12.5 W, but under certain conditions, as during tanker loading
(according to ISGOTT regulation), or the use of regional settings, a low power option (1 W) is
automatically selected.

5 Operational description
The operational description chapter assumes that the MX535B AIS Transponder and the MX51x display are
fully installed using the instructions found in the Installation chapter.
5.1 Powering the MX535B system
The MX535B turns on as soon as the external 12-24 VDC supply is connected to its terminals. It is
recommended that the external power to the unit be wired to a fuse or a circuit breaker for safety and
convenience. It will take about 1 minute warm-up time before the VHF transmission starts.
The power switch of the MX51x display unit does not control the power to the Transponder. Even if you
turn OFF the MX51x display, the AIS transponder will still be active. Note that the ship list will need some
time to recover when turning the Display unit on again. This is dependent on when the messages from the
different vessels are received. The message logs for sent and received messages will also be lost.
Note that the Transponder unit will issue an alarm when the display is shut down, and there may be no
means to acknowledge this alarm if the display is turned off!
5.1.1 Powering the MX51x display
To turn on the MX51x display, press the power key momentarily. To turn off, press the power key,
then highlight the YES softkey and press the ENT key or you can press and hold down the power key
for 5 seconds.
5.2 AIS General Setup
5.2.1 AIS System Setup

WARNING!
Use of AIS text messages between ships must not be used to avoid collisions when time is critical. AIS systems
are not required to have an audible alarm to indicate the arrival of all text messages.
The use of AIS text messaging does not relieve the vessel of other requirements, such as the Vessel Bridge-toBridge Radiotelephone regulations or of the requirements to sound whistle signals and display lights or shapes in
accordance with the International or Inland Navigation Rules.
Usage During Emergencies - With respect to using AIS safety related text messages in emergency situations,
users must be aware that they may not be received, recognized or acted upon as Global Maritime Distress
Safety Systems (GMDSS) messages would be by the Coast Guard, other competent authorities or maritime first
responders. Thus AIS must not be relied upon as the primary means for broadcasting distress or urgent
communications, nor used in lieu of GMDSS such as Digital Selective Calling radios which are designed to process
distress messaging. Nonetheless, AIS remains an effective means to augment GMDSS and provides the added
benefit of being ‘seen’ (on radar or chart displays), in addition to being ‘heard’ (via text messaging) by other AIS
users within VHF radio range (Ref: USCG Safety Alert 05-10).

5.2.6 AIS 6 - REGIONAL AREAS
Two VHF and one DSC receiver channels have been designated for AIS use worldwide.
These frequencies are:
• AIS 1 (Channel 87B, 161.975 MHz, (2087)
• AIS 2 (Channel 88B, 162.025 MHz, (2088)
• DSC (Channel 70, 156.525 MHz)
Under normal masterless operation, the MX535B AIS transponder operates autonomously with other
ships or AIS base stations using the AIS1 & 2 frequencies. When entering areas controlled by a
competent authority (i.e. Coast Guard) under Vehicle Tracking System (VTS) rules, the MX535B AIS
transponder can be polled and controlled by the VTS station. In this situation, data communication
between ship-to-ship and ship-to-shore stations is done through the DSC frequency (channel 70). All
VTS related activities are happening without any user intervention.
The controlling VTS base station schedules all ship’s data transmission and provides the regional
parameters shown in AIS 6 display, such as:
• Operating frequency, bandwidth and mode of Channel A & B receivers
• Northeast and Southwest corner coordinates of the region
• Zone size
• Date and time tag
These parameters are stored in the memory bank of the AIS transponder and can be displayed in the
MX420/AIS CDU. Up to eight regions can be stored by the transponder. The AIS constantly checks
the stored region boundaries and compares it to its own position. If the distance to the region
boundaries is greater than 500 miles from its own position or the time tag was older than five weeks,
those stored regions will be erased from memory.
The operator (administrator) has the option to do a full or partial editing of the regional parameters
when needed. The conditions below have to be observed when editing:
• Use the correct channel numbers (see table A-1 or in the AIS card)
• Latitude difference should be no less that 20 NM or larger than 200 NM
• Longitude difference should be no less than 20 NM or larger than 200 NM
• The zone size should be no less than 1 square mile or larger than 8 square miles
• Distance to the zone is less than 500 NM from you current position
Manual entries violating any of the above conditions will be rejected by the AIS transponder
without notifying the operator. If the region memory is full, the oldest regional memory will be
replaced by a newly accepted one.

6.1.3 Antennas
As a general rule, longer horizontal distances to other antennas will minimize the interference and
improve reception on all antennas.
Minimum distance is described in the figures below:

6.1.3.1 GPS Antenna
When selecting a mounting location for the antenna, keep in mind the following points.
1. Select a location out of the radar beam. The radar beam will obstruct or prevent reception of
the GPS satellite signal.
2. There should be no interfering object within the line-of-sight to the satellites. Objects within the
line-of-sight to a satellite, for example a mast, may block reception or prolong acquisition time.
3. Mount the antenna unit as high as possible to keep it free of interfering objects and water
spray, which can interrupt reception of GPS satellite signal if the water freezes.
6.1.3.1.1 GPS Globe Antenna
MX535B is delivered as standard with GPS globe antenna
(P/N AN156). The stainless steel stand and antenna coax
cable with TNC connectors in both ends for direct
connection between transponder and antenna are not
included in the kit.
The antenna mount is 1”-14 TPI standard mounting.
Outline Drawings
Calculation of cable length/attenuation etc… is described in chapter 6.2
42
6.1.3.1.2 Combined VHF/AIS
As an option to the individual VHF and GPS antennas, a combined antenna may be used in
conjunction with a signal splitter which will provide a common cable between the signal
splitter and the antenna, and two short jumper cables between splitter and transponder.
The combined antenna is delivered with a mounting bracket to be mounted on a mast.
Calculation of cable length/attenuation etc… is described in chapter 6.2
43
6.1.3.2 VHF Antenna
When individual GPS antenna is used, the CX4 VHF antenna must also be connected.
Location of the mandatory AIS VHF-antenna should be carefully considered. Digital
communication is more sensitive than analogue/voice communication to interference
created by reflections in obstructions like masts and booms. It may be necessary to
relocate the VHF radiotelephone antenna to minimize interference effects.
Install the VHF antenna referring to drawings in beginning of this chapter
The antenna should be connected using RG214 cable or better using BNC connector on the
transponder end and PL259 connector on the antenna end.
Calculation of cable length/attenuation etc… is described in chapter 6.2
44
6.2 Cabling
All outdoor installed connectors on coaxial cables should be fitted with preventive isolation such as
vulcanizing tape to protect against water penetration into the antenna cable.
Coaxial cables should be installed in separate signal cable channels/tubes and at least 10 cm away from
power supply cables. Crossing of cables should be done at right angles (90°). The minimum bend radius of
the coaxial cable should be 5 times the cable's outer diameter.
The cables should be kept as short as possible to minimize signal attenuation.
The type of cables used onboard vessels should be:
o
o
Halogen free
Fire resistant or Flame retardant type
o
Low smoke

For optimum performance of the transponder approximately +10 dB gain should be available when the
cable attenuation has been subtracted from the GPS antenna preamplifier gain. Note that Procom
AIS2/GPS and Comrod AC17-AIS are combined VHF/GPS antennas and additional attenuation from
connectors / diplexer must be taken in consideration. Some examples below:

Please keep the cables as short as possible, and be aware that 3 dB losses mean only half the output
power. If you have a transmitter delivering 12.5 W, and you have 3 dB losses in the cable, only 6.25
Watts will be at the antenna.
6.3.1 Cable between MX535B Transponder and MX51x Display Unit
The cable connecting the MX535B Transponder and the MX51x Display unit is a double twisted-pair cable
with individual shielding. Connections to the MX51x can be done easily through the junction box terminals
as shown below for the MX512 and MX510 display models.

In this configuration, both the external relay and the alarm unit are powered from external power source,
and the alarm unit is grounded through the external relay if an alarm occurs or the main power to the AIS is
removed or if the MX535B would become defective.
Other configurations may be used, but remember that the Alarm must function both on AIS Alarm
conditions and power failure to the AIS.
The Alarm relay is a normally open earth free relay contact, provided as an independent and simple
method for triggering an external alarm. The alarm relay is active in case of power off and is capable of
driving a 2 A current. The maximum voltage over the alarm relay must not exceed 48 V. The alarm relay is
deactivated upon acknowledgment of an alarm, either internally on the display unit, or by an externally
provided ACK sentence. If the Transponder power is lost, and the Alarm relay has power, the alarm will
be triggered. In this case, the only way to deactivate the Alarm is to power the Transponder unit or
disconnect the power source of the Alarm relay.

6.3.11 Detailed Description of Connections, fuses, factory reset etc…
1 The RS-232 terminals is only for factory use
2 The upper right preset button can be used to restore factory
settings at two levels. It is assumed that no SD card is present in
the transponder SD card reader.
a. To reset the IP settings for the transponder and the connection
to the display to default values if these setting have been
reconfigured and are unknown:
b.
Press the upper right preset button and apply power. Keep the
button pressed until the alarm LED starts flashing after approx.
10 seconds. Then release the button immediately.
The IP settings are now reset to factory default.
To restore the complete factory setting, all programmed
parameters are lost:
Press the upper right preset button and apply power.
Keep the button pressed.
Watch the alarm LED carefully, after approx. 10 sec it should
start flashing for 5 seconds and then stop. After some seconds
it will flash a sequence rapidly.
The preset button should now be released, and the factory
settings are now restored.
3 There are two fuses connected in series with the Main and
Backup power. There is no visual indication on fuse failure, but a
quick voltage measurement on each side of the fuse should give an
indication. If a fuse is blown, consider possible reasons for fuse
failure and replace the fuse if the reason for failure is repaired.
Replace fuses with identical fuses only. Use of other fuses or such will
make all warranty void.
4 The SD card reader is used for Software upgrades only. This must
be performed by Simrad trained Dealers/Distributors/Service Agents
5 The RST button is used to reset the almanac data of the internal
GPS in case of error. In order to reset the almanac, power off the unit
and then press the RST button for approximately 2s. When you
power up the unit again, the internal GPS will use some time to
obtain a fix. Approximately up to 15 minutes.
6 The GPS-Antenna Voltage jumper is used to select phantom feed
for an active antenna either 5 or 3.3 V. The maximum recommended
current drawn from these ports is 50 mA.
7 The termination jumpers for the sensors, external display, pilot
terminal and DGNSS beacon are made available in order to lower the
differential input resistance of the port in order to enable for longer
cables. The differential input resistance is approximately 7700 Ohm
without jumper and 240 Ohm with the jumper connected.

7.2 Not all vessels carry AIS
It is important to remember that not all ships carry AIS, in particular leisure crafts, fishing boats,
warships and some coastal shore stations including Vessel Traffic Service Centers.
7.3 Use of AIS in collision avoidance
-
As an anti-collision aid the AIS has some advantages over radar:
Capable of instant presentation of target course alterations.
Not subject to target swap.
Not subject to target loss in clutter.
Not subject to target loss due to fast maneuvers.
Able to detect ships within VHF/FM coverage.
IMPORTANT
When using the AIS for anti-collision purposes it is important to remember that the AIS is an
additional source of navigation information. It does not replace other navigational systems. The AIS
may not always give the right picture of the traffic in your area separately.
7.4 Erroneous information
Erroneous information implies a risk to other ships as well as your own. Incorrectly configured or
calibrated sensors might lead to transmission of incorrect information. It is the user’s
responsibility to ensure that all information entered into the system is correct and up to date.

8.2 Regional settings
The regional settings are primarily used by local base stations to assign special frequencies or transmitter
configurations for certain areas. It is also allowable to add or edit the regions, but this should be done with
caution, as incorrect frequency settings for an area will disable the functionality of the AIS system. Altering
the regional settings is protected by a user password. The Area named HIGH SEA, is the default area and
contains the whole world, except from the other regions, if defined.
Each Region is defined by the following parameters:
Area, defined as North East corner and South West corner.
Two channels used for VHF communications.
Rx/Tx mode is used to restrict the transmission to one of the two channels.
Transitional zone defines the area surrounding an area in order to switch the frequencies in a step
by step order.
The user is allowed to Add Regions manually, but caution is advised. It is not allowed to delete regions; they
will be deleted on timeout after 24 hours inactivity, if the ship is more than 500 NM away from the region, or
if the region is overwritten. There is a maximum amount of 8 regions in addition to the HIGH SEA region.
65
8.2.1 Transition Zone
A Region must be between 20 and 200 Nautical miles and within this region there will be a “Transition
zone” between 1 and 8 Nautical miles:
This zone is used for frequency transition so only one
frequency is changed at a time. There are defined
rules for how the AIS will behave through this zone.
The AIS will continuously monitor for its own position
and range to the regional areas defined. By entering
transition Zone of Region 1, frequency is changed on
the primary channel. The AIS is now sending the
primary frequency defined for each of the regions.
When the boundary for the Region 1 is crossed, the second frequency shall be changed. Then the primary
frequency for the old region (or default setting) is switched with the secondary frequency for the new
region. Then both frequencies have changed.
When entering another region, frequency transition is performed as described above with the frequencies
(settings) of the new region. When leaving a region, frequency transition is reset to perform the default
values.
66
8.2.2 Define Region
A Region must be between 20 and 200 Nautical miles as described above and you must define the
Longitudes and Latitudes of the South West and North East corners:
The values are defined by selecting these 4 buttons:
North East corner
South West corner
If the values are within 20 – 200 NM, they will be accepted, and you will be asked if you want to save it:

The Alarm relay is a normally open earth free relay contact, provided as an independent and simple method
for triggering an external alarm. The alarm relay is deactivated upon acknowledgment of an alarm, either
internally on the display unit, or by an externally provided ACK sentence. If the Transponder power is lost,
and the Alarm relay has power, the alarm will be triggered. In this case, the only way to deactivate the Alarm
is to power the Transponder unit or disconnect the power source of the Alarm relay.

8.2.8 Test VHF transmission
The communications test is used to verify the operation of the VHF communication by transmitting a request
for an acknowledgement to another ship (a.k.a. “pinging”). The user can select an AIS target from the list in
AIS 2 screen as long as the target is a Class A AIS transponder and “ping” it. This can be done under the AIS 4
screen. You can send a TEST text message to any class A AIS target and hopefully it will send an
acknowledgement message back. If the Acknowledgment is not received within 10 seconds, an alarm
message will be sounded. It is possible that the Communications Test has failed or the auto ACK feature of
the AIS target has not been activated. The user should retry with another target.
If the MX535B is in “Silent mode”, it is not possible to perform this test:
Using the AIS 2 screen, you can pick a target number using the TGT index number and use that to “ping”.
To “ping” a target, do the following:
1. Press the AIS key several times until the AIS 4 screen appears.
2. Press the EDIT key to bring up the cursor to “TGT:” field.
3. Enter the index (or TGT# i.e. #3) number of the target vessel as listed in the AIS 2 screen.
4. The MMSI field will be populated with the MMSI# for the selected vessel.

Press the right arrow key to bring up AIS 5 screen. If the pinged target sends an acknowledgement, the word YES will be indicated under the ACK field. If no acknowledgement is
received within 10 seconds, the word NO will be indicated and an alarm message will be
shown on the display.
8.2.9 Security Log
If the transmitter functionality of the transponder stops functioning for more than 15 minutes, this is
logged as an event in the AIS 11 (SECURITY LOG) screen.
