3.2.4 Recommendations Concerning Redundancy
If possible, the Electronics Unit should be supplied with the ship’s sensor data from two different sources,
e.g. in a dual installation with RADARPILOT 1000 the AIS can be supplied with sensor data from both
radars.
NACOS xx-3 only:
If two Ship’s Interfaces are existing because of redundancy purposes, the ship’s sensor output(s) of both
Ship’s Interfaces must be connected to the AIS Electronics Unit.
3.2.5 Recommendations Concerning the Connection of a (D)GPS to UAIS DBEG 3400
For an AIS stand-alone installation with the connection of an external (D)GPS position sensor, the
following prerequisites must be fulfilled:
NMEA Version
NMEA version 2.01 edition 04/1994 or newer is required. In addition to this, the optional checksum is
required. The AIS requires status information to check the data integrity.
All NMEA versions lower than 2.01 are not allowed for the use with AIS. To verify, that the NMEA version
is 2.01 or higher, check the settings of the GPS sensor.
Data Telegrams
For all NMEA versions lower than 2.3 the GGA message must be transmitted. Only the GGA message
transmits the information, that the differential mode is activated. This is set at the GPS receiver. If this
telegram is not transmitted, it is not indicated that a DGPS is connected to the AIS.
To check, that a DGPS is connected correctly, check the AIS State Menu of the connected DCU Debeg
3401.
AIS SW Version
In case that the prerequisites concerning NMEA version and data telegram are fulfilled an it is not indi-
cated that a DGPS is connected, it is necessary to perform a software update of the UAIS DEBEG 3400
Electronics Unit to the software version 220 or higher.
3.2.6 Emergency Power Source
It is recommended that an emergency power source such as a uninterruptible power supply should be
used. See Section 7 for information about the power consumption of the Electronics Unit.
