Network - NMEA (UDP) - 15

Lock User Interface

Means that you cannot change (by mistake) the properties of the currently defined messages.

Show Output Columns

If you enable the output column to show, each message that has been sent will be displayed in the dialog.

Notice that timing of the update in the dialog is less accurate than the actual timing of output.

NMEA Talker

You may define your own, by default it is 'GP'.

Output

Every update rate, by default. Other options are 2x, 5x, 10x, 30x, 60x or 300 times the update rate (from Db Setup). Disabled means the same as unchecking the checkbox in the drivers dialog.

Depth

Select from the list with available observations the observation that you want to use.

Note that only singlebeam depth, generic (miscellaneous) and/or ROV  depth (underwater sensor) observations will be displayed.

Checksum

Yes by default. At the end of the output message a two characters long checksum field will be added.
It is the absolute value calculated by exclusive OR-ing the 8 data bits (no start or stop bits) of each character in the sentence, but excluding '$' and '*'.

Output

Every update rate, by default. (See properties of DBT message above for more information)

Computation

From Priority List by default. Select from the list with available computations the one that you want to use

Node

Select from the list with available node the node position that you want to use

Datum

WGS'84 by default. The datum of the outputted position (lat/lon/height)

Time offset

Zero hours by default (meaning GMT time). This value affects the time field in the message

Deskew

No by default. If enabled, the position will be skewed to the moment of output. In that case the time in the datastring will also be the moment of being outputted.

Checksum

Yes by default. (See properties of DBT message above for more information)

Output

Every update rate, by default. (See properties of DBT message above for more information)

Heading

From Node result or from Observation:

Observation

Select from the list with available observations the observation that you want to use. Notice that any C-O or scale factor from Db Setup will be applied prior to output.

Computation

From Priority List by default. Select from the list with available computations the one that you want to use

Node

Select from the list with available nodes the node that you want to use. The heading of this node is then used for output.

Checksum

Yes by default. (See properties of DBT message above for more information)

Output

Every update rate, by default. (See properties of DBT message above for more information)

Temperature

Select from the list with available observations the observation that you want to use.

Checksum

Yes by default. (See properties of DBT message above for more information)

Output

Every update rate, by default. (See properties of DBT message above for more information)

Target ID

Target number for identification. Select the number from the list (00 - 99).

Computation

From Priority List by default. Select from the list with available computations the one that you want to use.

Target Node

Select from the list with available node the node that you want to use.

Own vessel node

Select from the list with available node the node that you want to use.

Unit

Distance or speed unit, can be: meters, meters / second (M); kilometers, kilometers / hour (K), Nautical miles, knots (N), International miles, International miles / hour (S)

Bearing

True bearing will output the target course and target bearing from own ship relative to true north. Relative bearing will output these values relative to the own vessel's heading.

Deskew

No by default. If enabled, the positions of the target and the own vessel will be skewed to the moment of output. In that case the time in the datastring will also be the moment of being outputted.

Checksum

Yes by default. (See properties of DBT message above for more information)

Output

Every update rate, by default. (See properties of DBT message above for more information)

Computation

From Priority List by default. Select from the list with available computations the one that you want to use.

Node

Select from the list with available nodes the node that you want to use. The COG and SOG of this node will be used to calculate Set and Drift, together with the selected water speed observation.

Water speed

Select from the list with available observations the observation that you want to use.

Checksum

Yes by default. (See properties of DBT message above for more information)

Output

Every update rate, by default. (See properties of DBT message above for more information)

Checksum

Yes by default. (See properties of DBT message above for more information)
