10.3.1 DGNSS message 17
When the R60 is setup for message 17 (DGNSS) transmission
4
there has to be some
source for the DGNSS data. The standard specifies that one possible source is VDM
input.
Consequently when a VDM with encapsulated message 17 is input to the R60 the
message will be saved internally waiting for the message 17 slot, instead of outputting
it on the VDL like other VDM messages.
This behaviour only happens for VDM messages with encapsulated message 17 where
the output channel in question is setup for message 17 transmissions. For a channel
with no message 17 transmission schedule, a received encapsulated message 17 is
treated like any other VDM input and is not saved but output onto the VDL.

Message 17 is enabled and configured in the “Reporting Rates” category. See section 6.7.
