6.2 Transponder Unit
The Transponder Unit contains
all the core functionality of the
AIS system and can function as
a separate unit connected to
other display solutions
confirming with the AIS
message format. It consists of a
splash proof Alumina casing
with the following connection
possibilities:
VHF antenna and GNSS antenna
Display connector (Ethernet)
External display connections
(“ECDIS Port” and “Pilot Port”)
Sensor connections
DGNSS Beacon receiver connection
Alarm relay
Complies with the environmental requirements
specified in IEC 60945 Ed.4 Exposed, and is certified for IP56 /IPX6. The operating temperature is from -25°C to
+55°C and storage temperature from -30°C to +70°C
The receiving section of the Transponder consists of three VHF receiver circuits, for continuous reception on both
AIS channels (configurable from 154MHz-164MHz) and the DSC channel (ch70).
The transmitter circuitry is connected to the same antenna terminal and is switched internally.
Functionality for direct reporting with satellites (Long-range AIS broadcast) is implemented and operates when so
configured by the competent authorities.
The internal power supply of the Transponder is galvanically isolated in order to protect the internal circuitry and
operates in a wide voltage input range from 10.8V – 31.2V. A backup power source can be connected if available.
Automatically switching to backup power source will take place if the main source of power is lost.
