Dual Channel Receivers

his receiver is just being launched in

Europe with three variants. The entry level

101-E has NMEA input and output, accepting

data from an external GPS and adding the AIS

data to it for output. The 101 adds to this a PC

interface (USB or RS232), and if USB is used

for data then it can also be used for power.

The 101-G model includes a GPS antenna,

instead of accepting GPS data over the NMEA

input. The unit comes with Amec’s AIS Viewer

software, which is a good

tool for tracking

vessels.

omar produce a range of three receivers,

all based on the same core electronics

but with different interfaces. The AIS-2-NMEA

has an NMEA output, while the AIS-2-USB

uses a PC’s USB port for both power and data

output. The AIS-Multi adds an antenna splitter,

an NMEA multiplexer, and both NMEA and

USB outputs.

he FA-30’s big advantage is support for

Furuno’s Navnet Ethernet interface. It also

comes with a cut-down version of Maxsea for

AIS tracking (which only works with Navnet).

Although there is an NMEA input, this is for

when the receiver is used with the AIS display

unit (not tested here), and incoming NMEA

data is not output with the AIS data. The FA-30

is bulky compared with other receivers.

key feature

of the

SeaVieweR is

that it can be

upgraded to

the SeaTraceR

transponder

for about

£200, ideal if

you think you

may want a

transponder later. The unit is designed to take

a GPS antenna for outputting position data

with the AIS data stream – the NMEA input is

just for acknowledging alarm messages that

may be in the NMEA output. Included is the

proAIS software, which is more of a

conﬁguration and diagnostics tool than a

tracking tool.

his is the dual channel version of the

SR161. As well as the RS232 output, it

also has a 4,800bps input, so all incoming

NMEA data can be passed through to the

output stream.

As an RS232

interface is

used, and not

NMEA, there is

a common

ground to the

input and

output – this is

not compliant

with the NMEA

spec, though

will generally

work OK.

his receiver has an NMEA input at

4,800bps and also a port for a GPS

antenna, with both the GPS and incoming

NMEA data being multiplexed to the output

port. As with the SR162, an RS232 interface is

used instead of NMEA.

avicom’s

has dual AIS

receivers

inside. It can

show the AIS

data on the

display either

as a list of

vessels, or as full details on a vessel, or as a

basic plot. Although useful as a backup, this is

too limited for normal use, so you will need to

link the unit to a plotter. Data is output as

either NMEA or RS232. Although it takes GPS

input for the DSC capabilities, this is not

output with the AIS data.
