Correcting a displayed boat speed
SPEED CORR.(-50~+50%)
0%
When the water temperature/speed sensor
ST-80/90/100
is connected, you can correct currently displayed
boat speed data
Selecting a water temperature data source
TEMP DATA
INTERNAL EXTERNAL
TRI
connector and
SER DATA
connector are provided on the rear side of the incoming signal indicator unit.
Both of them accept water temperature data. When acquiring the data from
SER DATA
connector, you must
select a proper input data format referencing the
"Selecting an input data format"
.
INTERNAL
...........This mode is used for collecting the water temperature data from the water
temperature/speed sensor
ST-80/90/100
connected to
TRI
connector. If the water
temperature data is absent,
"0.0"
appears in the data display space.
EXTERNAL
..........This mode is used for collecting water temperature data from the water temperature sensor
connected to
SER DATA
connector. If the water temperature data is absent,
"X.X.X.X"
appears in the data display space.
Correcting a displayed water temperature
TEMP CORR. (-9.9~+9.9 C)
0.0 C
When the water temperature/speed sensor
ST-80/90/100
is connected to
TRI
connector, you can correct
currently displayed water temperature data.
Selecting an input data format
When acquiring data from the GPS navigation system or electronic compass via the SEA DATA connector,
input data must have one of the following formats.
FORMAT
0182 0183 COMPASS
0182
...................Acquires data on the current position (latitude and longitude) in the NMEA0182 format.
0183
...................Acquires data on the current position (latitude/longitude or LOP), bearing of your boat (VTG
sentence), external boat speed and external water temperature in the NMEA0183format.
COMPASS
...........Acquires data on bearing of your boat (HDM sentence) in the NMEA0183 or DC400 format.
For the data (sentence) entered in the NMEA 0183 format, refer to the
"NMEA 0183 output data format Ver.
1.5/2.0"
.
If the data does not contain a sentence or you cannot receive the data,
XXXX
will appear in the data display
space.
If the navigation system or electronic compass is not equipped, data won't be displayed even if you may
specify the format.
Selecting gain type
For general applications where bottom depths are continually changing, set the gain type to
2
(default value).
For consistent shallow water use (under 50 feet) select gain type
1
.
GAIN TYPE
1 2
1
......................Gain changes linearly by the gain number.
2
.......................Gain changes logarithmically by the gain level number.
