SNX-300
When another device (for example an INS) wishes to set one or more of the bit masks it sends one or
more NRM sentences to the NAVTEX receiver. When another device wishes to determine the current
values of the bit masks it sends a query sentence to the NAVTEX receiver as follows:
$--CRQ,NRM*hh<CR><LF>
On receiving this query, the NAVTEX receiver will respond with one NRM sentences for each mask type
and frequency combination that it supports. For example, a NAVTEX receiver which supports separate
storage, printer and INS masks for each of three receiver requencies will
return a total of nine NRM sentences in response to the above query.
Example usage:
$INNRM,2,1,00001E1F,00000023*57
This example specifies that message identifiers ‘A’, ‘B’ and ‘F’, received from transmitter areas ‘A’ to ‘E’
and ‘J’ to ‘M’ on 490 kHz should be sent to the printer port when they are received. Note that this
command sets the printer mask for future use; there is no immediate output generated as a result of
receiving this command.
Example usage:
$INNRM,0,2,00001E1F,0FFFFFFF*21
This example requests that all currently stored messages of all message types, received from
transmitter areas ‘A’ to ‘E’ and ‘J’ to ‘M’ on 518 kHz should be immediately returned to the requesting
device as a series of NRX sentences. Note that this command does not update any of the stored masks.
