Class B AIS Transponder for
Pleasure & Fishing Boats
What is an AIS transponder?
An AIS transponder on your
boat automatically receives information broadcast by
other AIS-equipped vessel's and base stations, all while
your own vessel's static and dynamic information is
being transmitted. AIS signals may reach where radar
cannot, showing AIS-equipped vessels that might
otherwise be hidden, such as on the other side of an
island or behind a larger vessel. SOLAS commercial
vessels are already required to carry a Class A AIS
transponder, so your position will be known by nearby
large vessels. The MA-500TR increases your safety at
sea.
Class B AIS transponder
The MA-500TR is a Class B AIS
transponder for Non-SOLAS vessels such as pleasure
craft, workboat and small vessels. Your vessels
information will automatically be transmitted at fixed
intervals or under base station control. The MA-500TR
receives dual AIS channels (Ch. 87B and Ch. 88B)
simultaneously and receives both Class A and Class B AIS
information.
Transmitted information by MA-500TR is
• MMSI code
• Vessel name
• Call sign
• Type of ship
• GPS antenna position
• Ship's position
• SOG (Speed over ground)
• COG (Course over ground)
• UTC date and time
• GPS antenna type
• PA (Position Accuracy)
Simple operation
The Plotter display looks like
a marine radar display. North-up, course-up and range
zoom from 0.125 NM to 24 NM are supported. The Target
list display shows all detected AIS equipped vessels and
targets. The Danger list display shows a list of vessels
that are within 6 NM CPA and 60 minutes TCPA from your
vessel. The Danger list can be sorted by CPA or TCPA
order. In addition to these display types, the Detail
screen shows various information about the selected AIS
target.
CPA and TCPA for
collision-risk management
When a vessel comes into the
CPA and TCPA range, the vessel icon blinks on the
Plotter display and emits a beep sound. When connected
to external audio equipment installed on the deck or
tower, the collision alarm function will alerts you even
when you are away from the AIS transponder.
Individual DSC call*
When connected to a compatible
Icom VHF radio, it's easy to make an individual DSC
call. Select a vessel using the MA-500TR's cursor keys
and then push the "DSC" button on the MA-500TR. It is
not required to input an MMSI number manually.
* This function works only
when a compatible radio is connected such as new
firmware versions of the
IC-M603 or M505
series.
100 Waypoints memory
Up to 100 waypoints can be
stored on the waypoint list. The "MOB" button allows you
to set a waypoint on your current position instantly.
Safety-related message
When the MA-500TR receives a
safety-related message from a Class A AIS transponder,
the message icon appears on the Plotter display. Up to
20 received DSC messages are automatically stored in the
log memory.
3-line NMEA input/output
The MA-500TR has 15-pin D-SUB
connector providing 3-lines of NMEA input/output on the
rear panel. The supplied NMEA connector cable simplifies
the installation and connection to the VHF radio and
other navigation equipment.
GPS receiver needs the
MA-500TR
The MX-5000 GPS receiver is a
12 channel parallel GPS receiver with SBAS function.
