Configuration of AIS
Figure 11
– AIS Configuration with 38400 Baud Rate
Setting up the Hardware for AIS
Control Centre, supplied on the CD (or available for
download from
), allows a quick set-up
for AIS using the configuration file included.
From the menu select
‘File → Load Configuration File’
and select
“NDC-4 config for AIS.ini”
file from the
install directory. Read the pop up and click
‘OK’
.
This will change the settings for OPTO IN 2. The
configuration tab will set 38400 Baud (AIS requires NMEA
0183 HS). The Inclusion List is set to block all AIS data
from being sent to ISO OUT 1 which is typically kept at
4800 Baud. Filtering does not affect the USB/RS232 port,
all the AIS sentences will still be outputted on this port.
Note:
The use of AIS at Baud rates lower than 38400
cannot be recommended as this could cause random AIS
target data to be lost in areas of high target density.
To enable these settings on the NDC-4 click on the
‘Send
to Hardware’
button on
BOTH
the
‘Port Configuration’
and
‘Inclusion List’
tabs.
The AIS device should then be connected to the NDC’s
‘OPTO IN 2’
as shown in
‘Figure 21’
, with any other
talkers connected as required. The device for receiving
the AIS data (chart-plotter or PC) should be connected to
‘ISO OUT 0’
, or the USB port.
The remaining ports can be re-configured by the user as
needed using Control Centre. Refer to “Using NDC Control
Centre” on page 16 of the “Full user manual” available on
the CD and from
for full detailed
information on how to use Control Centre.
