Requirements
The
AIS
WatchMate
is available in several packages depending on
your situation. If you purchased an
AIS
WatchMate
without an AIS
receiver or transponder, then you must supply one.
In addition, a suitable VHF antenna must be supplied by the user and
a GPS is required to provide position and navigation information for
the user's vessel.
The following are required for installation:
●
AIS receiver or transponder that outputs NMEA 0183
“VDM” sentences at 38400 baud (IEC 61162).
●
A suitable VHF antenna or antenna splitter for the AIS
receiver or transponder.
●
A GPS unit that outputs NMEA 0183 “RMC” sentences at
4800 or 38400 baud. Some AIS receivers and transponders
include an integrated GPS. If you have one of those, then it is
not necessary to use another GPS.
●
10-16 volts DC power.
GPS Datum
Your GPS should be set to output position data using the WGS 84
datum. Because WGS 84 is the datum used by the AIS system,
inaccurate bearings, range and CPA calculations may result if the
GPS datum is not set properly. Please consult the owner's manual for
your GPS for more details.
