output of the internal battery and the 115 is the sounding return quality
number from 70 to 135.

Format ASCII mode (example output below)

0.48
0.48
0.48
0.48
0.48
0.48
0.48

ASCII mode is used mainly by Leica users and 0.48 would be the depth

Format 2 DBT NMEA mode (example output below)

$SMDBT,1.6,f,0.48,M,,*5C
$SMDBT,1.6,f,0.48,M,,*5C
$SMDBT,1.6,f,0.48,M,,*5C
$SMDBT,1.6,f,0.48,M,,*5C
$SMDBT,1.6,f,0.48,M,,*5C
$SMDBT,1.6,f,0.48,M,,*5C

This is a standard NMEA output which can be used with various logging
software.

Format 4 Odom SBT mode (example output below)

et 47
et 47
et 47
et 47
et 47
et 47

This is an Odom output; it can be used if you have logging software that
needs an Odom data format.

Format 5 Deso 25 mode (example output below)

DA 0.48 m
DA 0.48 m
