Description
When the ST90 system communicates
with peripheral devices (for example
navigation sensors), the information is
contained in
datagrams .
The term "datagram" has been defined
as follows:
A self-contained, independent
entity of data carrying sufficient
information to be routed from
the source to the destination
computer without reliance on earlier
exchanges between this source and
destination computer and the transporting network.
https://tools.ietf.org/html/rfc1594, April 2016
The majority of the datagrams used by the ST90 system are defined by the National Marine
Electronics Association (NMEA). Other proprietary datagrams are defined by third-party
organizations or by Kongsberg Maritime.
Any information in a datagram, for example the current depth, may be provided in different
datagrams from several sensors. Due to a number of reasons (environmental conditions,
installation, configuration, accuracy, etc.), the numerical values provided can be different
from one sensor to another.
Several sensor are provided on the
Sensor Configuration
page, one for each type of
information. Select the sensor you wish to configure in the
Sensor
list. For each type, you
can define a priority sensor by rearranging the datagrams in a list. You can also define
manual values in case a sensor is unserviceable, or not installed.
Tip
The ST90 system can communicate with several different sensor types. Use the
Sensor
Installation
page to define which external sensors your ST90 system will import information
from. You must also specify which datagram formats to use. The
Sensor Installation
page is
located in the
Installation
dialog box.
A summary of all the sensors that are connected to the ST90 system is provided in the
Diagnostics
dialog box.
When you save echo data in RAW format, all sensor data are included.
