4.5 NMEA 0183 connection
The AIS700 can transmit data to devices connected via
NMEA 0183. The AIS700 is connected using the NMEA
0183 wires located on the Power/data cable.
Note:
Whilst it is possible to output both AIS and
GNSS data, it is NOT recommended that you output
GNSS data to external devices as this can cause data
conflicts and / or performance issues. The ability
to output GNSS data is intended for diagnostics
purposes only.
The AIS700 includes 2 bidirectional NMEA 0183 ports.
The baud rate for each port can be configured using
the supplied proAIS2 software. Both ports can be
multiplexed which enables any data provided to one
port to be combined with AIS data and output on the
other port.
Typically port 1 is connected to an MFD and configured
for 38,400 baud rate, the baud rate required for AIS
data transfer. Port 2 is connected to a Heading sensor
or other NMEA 0183 device and configured for 4,800
baud rate.
Important:
To avoid potential data conflicts or loops multiple
network protocols should not be connected to the
same device i.e.:
• Do NOT connect the AIS700 to a MFD using NMEA
0183 and SeaTalkng ®/ NMEA 2000 connections
at the same time.
• Do NOT connect the AIS700 to a VHF Radio
using NMEA 0183 and SeaTalkng ®/ NMEA 2000
connections at the same time.
• Do NOT connect the AIS700 to a PC using NMEA
0183 and USB connections at the same time.
• If you are connecting to an AIS capable VHF Radio,
you must disable the VHF Radio’s AIS function first.
Refer to your Radio’s documentation for details on
disabling the AIS function.

cable are identified below.

4.6 GPS (GNSS) antenna
connection
Connect the supplied GNSS antenna to your AIS700
using the GNSS antenna connection. The antenna
is fitted with a 10m (33ft) cable for connecting to the
AIS700.
Note:
Do NOT connect any other antenna than the
one supplied with your AIS700.
If the antenna is not connected or connected incorrectly
then your AIS700 will operate in Silent mode, the AIS700
will not transmit but will still receive.
