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.
