MARIS ECDIS900 Installation Manual
DATAGRAM TYPES
All UDP multicast datagrams used in the ECDIS900 contain one of the following strings,
followed by a null character (all bits set to zero) as the first six bytes of the datagram:
•
"RaUdP" for transmission of binary file e.g., screen dump to VDR.
• "RrUdP" for transmission of retransmittable binary files e.g., route transfer to and from
the ECDIS900.
BRIDGE ALERT MANAGEMENT INTERFACES
The system supports Bridge Alert Management (BAM). The ECDIS900 uses a communication
protocol based on an interface using a series of sentences: ALF, ALC, ACN, ARC and HBT.
The interface for alerts complies with the IEC 61162-1 standard.
