RF connections
In a typical AIS500 system:
• The boat's existing VHF antenna connects to the ANTENNA
connector on the AIS500 transceiver.
• The supplied 1 m RF cable connects the antenna connector on
the boat's existing VHF set, to the VHF RADIO connector on the
AIS500 transceiver.
If this arrangement results in unacceptable degradation of the
performance of the VHF radio, separate antennae should be used
for the AIS500 transceiver and the VHF radio. In this case, the
supplied 1 m RF cable is not used and the VHF RADIO connector
on the AIS500 transceiver remains unconnected.
Note that when the AIS500 transceiver transmits, there is a very
brief interruption to the boat's VHF receive function. This may
be noticeable during when a long, continuous broadcast is being
received.
GPS connections
The GPS supplied as part of the AIS500 system has a fitted 10 m
(33 ft) cable to connect to the AIS500 transceiver GPS connector.
NMEA connections
The AIS500 transceiver has a fitted cable which provides prepared,
bare-wire NMEA0183 connections at both 4800 baud and
38400 baud rates, as follows:
