Raymarine AIS250 User Manual

12 Raymarine Automatic Identification System Receiver
Antenna
Your Raymarine AIS receiver does not strictly require a dedi-
cated antenna. The on-board antenna splitter enables you to
connect your existing VHF radio antenna to your AIS receiver
and then connect from the AIS250 to your VHF. However in
doing so you may experience some level of degradation to your
VHF’s receiving performance. A separate VHF antenna is
recommended if you wish to maintain the same performance.
2.6 Cable runs
Caution: DO NOT cut cables or remove connectors as this
will severely reduce system performance. If a
longer cable is required you will need to purchase
a replacement cable from a suitable dealer. In the
event a shorter cable length is required, secure
excess cable out of the way.
Consider the following points before installing the system
cables:
• You may need to connect the antenna cable and the antenna
connector cable from the AIS250 receiver to your VHF radio.
So ensure enough room is allowed to comfortably insert and
remove connectors from the unit.
• All cables should be adequately protected from physical
damage and exposure to heat.
• Avoid passing cables through bilges or doorways, or close to
moving or hot objects.
• Acute bends and squashing of the cable must be avoided.
• Where a cable passes through an exposed bulkhead or
deckhead, a watertight gland or swan neck tube should be
used.
• DO NOT pull cables through bulkheads using a cord
attached to the connector. This could damage the connector.
You will need to run the following cables:
• 1.5 m (5 ft.) Power cable.
• 1.2 m (4 ft.) AIS250 to VHF radio connector cable (enables
you to use the existing VHF antenna cable).
Power cable
A 5 ft. (1.5 m) power cable is supplied, and must be protected by
a 1.0A resettable fuse/circuit breaker
Antenna cable
A 4 ft. (1.2 m) AIS250 to VHF cable is supplied. (This allows you
to use your existing VHF antenna for dual purpose, i.e. AIS250 &
VHF reception).
