AIS500 transceiver
This product is NOT approved for use in hazardous/flammable
atmospheres. Do NOT install in a hazardous/flammable atmosphere
(such as in an engine room or near fuel tanks).
The AIS500 transceiver must be fitted in a location where it is not
likely to be stepped on or tripped over, and which:
• Is close enough to allow connection to the boat’s VHF set with the
3 ft (1 m) RF cable supplied.
• Is at least 3 ft (1 m) from an engine, compass or any magnetic
device.
• Has at least 6 in (100 mm) of clear space below, to allow access
for cabling and adequate cable bends.
• Is maintained at a temperature between –10°C (14°F) and 55°C
(130°F).
• Is maintained in a dry condition and where there is no likelihood
of the transceiver being splashed.
• Does NOT have a flammable or hazardous atmosphere.
Power supply
The AIS500 transceiver requires a 12 V dc or 24 V dc power supply,
typically from a circuit breaker on the boat’s power panel or from a
fuse block near the transceiver.
VHF antenna requirement
The AIS500 transceiver requires inputs from both GPS and VHF
antenna.
The AIS500 transceiver has an inbuilt VHF splitter to enable
you to connect your existing VHF antenna directly to the AIS500
transceiver, then route the split signal from the transceiver to your
VHF set. This may cause some degradation of performance of your
VHF set. If the level of degradation is unacceptable, we recommend
you use separate VHF antennae for the AIS500 and the VHF set.
The loss values for the inbuilt splitter are given in the Specification
section.
GPS antenna requirement
A GPS antenna is supplied with the transceiver and must be
installed in accordance with the instructions given here. Do NOT
connect any other GPS antenna to the AIS500 transceiver.
The GPS antenna can be mounted either on a flat horizontal surface
or on a suitable pole.
• If you intend surface mounting the antenna, ensure you have
access to the underside of the mounting surface.
• If you intend pole-mounting the antenna, the pole needs a 1 inch
14 TPI thread.
Important: The main requirement of the intended location for the
GPS antenna is that it gives a good direct line of site to the entire
sky, right around the horizon.
Ensure that the intended mounting location is:
• Open and clear of any obstructions (such as masts, search lights,
or other structures) that could block line-of-sight to the sky.
• As low as possible, to keep the antenna as stable as possible.
The more stable the unit, the more effectively it will track satellites
and provide stable data.
• As far as possible (at least 1 m (3 ft)) from other antennae and
electronic equipment.
Do NOT mount the antenna:
• In any area where it could be stepped on or tripped over
• Up a mast. This will cause the antenna to swing and give
significant errors in position data
• In the direct path of a radar beam.
