2.3 Standard Data Products
2.3.1 Depth Output via Serial or UDP Port
The Echotrac E20 is capable of generating ASCII depth data messages via serial or UDP port COM3.
The following depth data messages are supported by the Echotrac E20:
o Depth
 Echotrac SBT
Example: “
<sp>et<sp><sp>54321<CR>
”
 Echotrac DBT
Example: “
<sp>ETOL<sp>54321<CR>
”
 DESO25
 NMEA 0183: $SDDBS
Example: “
$SDDBS, 3.3,f,1.9,M,0.6,F*AB
“
o Motion
 DESO DDV Heave
Example: “
DH01.23<sp>m<CR><LF>
“
o Draft
 DESO DDV Draft
o Sound velocity

DESO DDV Sound Velocity
o Universal message
 Echotrac DBX
Example: “
$DBX,2019-09-30T205959.999,2,00123.999,-216.14,00.950,
00124.321,-218.14,01.100,1,-002.230,1,1435.98<CR><LF>
”

2.3.2 Echograms
The Echotrac E20 provides raw data of both channels on Ethernet, in s7k format, including all
auxiliary sensor data of sensors connected to the echosounder.
o The raw echogram information is in full resolution of sampling rate.
o The data of all auxiliary sensors connected to the E20, such as Heave and GPS, are provided
in the s7k record in full resolution as well.
o Acoustic basic information, such as used transmit pulses, basic echosounder settings,
operation modes, and receive gain, is part of the s7k record as well, to allow receiving
software to interpret the raw echogram values in a meaningful way.
The main singlebeam record types are 10000 SBES channel settings, 10018 SBES echogram water
column data, and 100027 SBES raw detection data. For details, refer to the Data Format Definition
document (see
Appendix A – Reference Documentation ).
