TT-3000E mini-C GMDSS User Manual
position reports in return to a poll. When a Capsat mobile
unit responds to a Poll, the response is either forwarded to
the terrestrial user at once, or it is stored at the Land
Station for later retrieval. When receiving a poll the
transceiver will generate a file containing the data of the
poll. These files named POLLFILE.000, POLLFILE.001,... will
be transferred to disk. No further action will be taken.
5.5.39 DNID - THE DATA NETWORK ID
The DNID is a unique number, which serves as a link
between the terrestrial user and the mobile unit(s), i.e. the
DNID is used when the terrestrial user issues a Poll and also
when the mobile responds. A user may very well have
several DNIDs. This is also the case for the mobile.
When several mobiles have the same DNID, this is called a
group. Each mobile in the group is also designated a
member number, which enables the terrestrial user to
differentiate between the mobiles in the group. This is
especially important, when responses from the mobiles are
processed at the premises of the terrestrial user.
The user interface allows you to enable or disable DNIDs. If
a DNID is disabled you will not receive any poll with this
DNID or be able to use it for position reporting.
To change the status of a DNID:
1. Choose Options, Configuration, DNIDs (Alt, O,
C, D) to have the DNID window displayed.
2. Choose Enable or Disable to change the status
of a DNID entry. The entries can have the
status Enabled, Disabled, T&TPos on and
T&TPos off. The last two types will only
appear if you have set this DNID to use the old
T&T type position reporting.
