Auto Detection; Advanced - Simrad Maris ECDIS900 Technical Manual

Auto detection

ORE SETTINGS
Depending on the selected norm additional settings may be required:
NMEA 0183: use the option when a GPS is connected to set up the route transfer
•
between ECDIS and the GPS
E/T Target Output: targets acquired by Maris PC Radar Kit can be sent on serial line with
•
NMEA format. Then target table can be used by another application.
Lehmkuhl Gyro.
•
AIS Transponder. Adjustment may be necessary during installation.
•
NMEA Gyro Emulator. Sensor Monitor can be used as Gyro repeater.
•
Network repeater may be used when several PCs run ECDIS.
•
REMARK
Other norms are related to the VDR and are not described in this documentation
When the adequate norm is selected in the list, NMEA for example, the input data flow is
automatically analysed by Sensor Monitor and the different parameters extracted from the
sentences (Speed through Water, Wind direction, etc.).
When Auto detection is ON and Sensor Monitor starts, the Sensor Monitor application
selects the first valid sentence for each data type. For example, a GGA sentence may
be selected for a position.
In order to select another sentence for the same data (GLL for example), it is necessary to set
Auto detection OFF and toggle the check box in front GLL.
REMARK
This feature may be used to ignore a specific sentence and data.
C
HECKSUM VALIDATION
NMEA-based and NMEA-like protocols provide CRC-based checksum to validate integrity
check for all sentences.
Checksum validation increases data reliability but takes some time and resources. For strong
and fast data flow (such as AIS) it could be significant.
The button Advanced allows the user to check an input and output data flow with a terminal
27
window, which displays the raw data acquired on the specified serial port.
