Optional Silent Mode switch
A switch can be connected to the transceiver to enable and disable
‘silent mode’ (see Step 4 and 5 in Installation procedures, chapter 3.
A latching toggle switch is required to use this feature.
VHF antenna cable
Please check that the VHF antenna you intend to use has sufficient
cable to reach between the VHF antenna and the AIS transceiver
unit. If it is not sufficient, you will need an extension cable. Please
contact your dealer for details of suitable products. For reference,
the VHF antenna connector type on the AIS transceiver unit is
SO 239, and is intended to mate with a PL 259 connector.
Power and data cable
The AIS transceiver unit is supplied with a 2 meter long power and
data cable as an accessory. If you require longer cables to reach your
power supply, please ensure the cables are capable of carrying cur-
rents of up to 2A peak and 200mA on average. Means of connecting
the cables together will also be required. The use of Scotchlok
TM
connectors is recommended for this purpose.
Chartplotter
To display received AIS messages from other vessels on your chart-
plotter, you will need to connect your AIS transceiver to your chart-
plotter. Please refer to the user manual supplied with your chartplot-
ter for details of how to connect and configure your chartplotter for
use with AIS devices. For general guidance, your chartplotter should
be configured to accept NMEA 0183 data at 38400 baud (sometimes
referred to as ‘NMEA HS’ in the plotter configuration menu).
Alternatively, if you use an NMEA 2000 network on your vessel, you
can connect the AIS transceiver to your NMEA 2000 network via the
supplied cable. Refer to your chartplotter manual for making NMEA
2000 connection. You may also need to enable the display of AIS
targets in the chart options.
Connection to a PC or Mac
If you choose to use a PC or Mac with suitable charting software
to display received AIS messages from other vessels, this can be
accomplished by connecting to the USB connector on the AIS
transceiver.
