User manual

Main (left) tick-box area:
Each NMEA 0183 sentence has its own individual tick-
box, and is intended for the advanced user to ne tune
the selection to exactly what is required (as this requires
detailed knowledge of NMEA 0183 sentences).
Sentence Groups (right) tick-box area:
To make selection of NMEA 0183 sentence’s easier,
all sentences of a particular type have been collected
together, and is primarily intended for the novice user who
does not know which sentences contain what information.
The NMEA sentence collections are designed for quick
list conguration; each collection inuences all the NMEA
sentence tick-boxes in the main (left) area that contain the
selected information.
The tick-box operation is straightforward: if the box is
ticked, the corresponding NMEA sentence will appear on
the combined NMEA output. Conversely, if the box is not
ticked, that NMEA sentence will be blocked and not appear
on the combined output.
To completely disable the Inclusion
List for a particular channel,
click on the Clear all sentences
button. The list status indicator will
then change from the green List
Enabled to red Pass all data.
The Sentence Total box will also show that ‘0’ sentences
are selected.
Once disabled (and Pass all data displayed), all NMEA
sentences will be passed to the NMEA combined output
- no ltering will occur on this channel. This is only useful
when trying to pass an NMEA sentence that is not available
for selection in the Inclusion List and is not normally used.
The buttons Clear all sentences and Set all sentences
are useful to quickly reset or set all tick marks. This allows
for quick conguration of the Inclusion List without having
to click on every tick box. For example, if only a couple
of sentences are required to be set, press the Clear all
sentences button followed by selecting the couple of
required sentence IDs.
Sentence Total:
The total number of NMEA sentences currently
selected / enabled for the current channel / port
is displayed in the bottom right corner. This is
purely for user information and interest.
Get from Hardware:
Reads/retrieves the current Inclusion
List information, for all channels, from
the connected NDC hardware. This will
overwrite any current settings held by
the Control Centre Inclusion Lists; if the current settings
must be remembered, the File → Save Conguration
le main window menu option should be used before
requesting this operation.
Reset to defaults:
Returns all channel Inclusion Lists to the
factory default – all Inclusions Lists are
disabled on all channels, which allows
all sentences to be passed by default.
Send to Hardware:
Finalises the Inclusion List editing
operation. If any alterations to the list
have occurred, the Control Centre will
now attempt to download the new settings
to the attached Actisense™ NDC hardware. The Flash
Hardware Control window will appear for the duration of
the download and the details of the conversation can be
viewed in the NDC Hardware Connection Status window
(advanced users only).
Note: Pressing any of the threes buttons above will only
affect the Inclusion List settings - all Port Conguration
settings will remain unaffected as they are controlled by
their own independent set of buttons.
