Simrad EK500 Depth

This proprietary Simrad telegram was defined for the EK500 scientific echo sounder.
It provides the current depth from three channels, as well as the bottom surface
backscattering strength and the athwartships bottom slope. This telegram has be defined
for output on either a serial line or a local area network Ethernet connection.
Serial line format
D#,hhmmsstt,x.x,y.y,t,s.s<CR><LF>
Serial line format description
1 = identifier, can be
D#
2 = current time; hour, minute, second and hundredth of second
hhmmsstt
3 = detected bottom depth in meters
x.x
4 = bottom surface backscattering strength in dB
y.y
= transducer number
5
t
= athwartships bottom slope in degrees
6
s,s
Ethernet format
The Ethernet line output is specified using a "C" programming language structure. Note
that this format does not include carriage return and line feed characters at the end of
the telegram.
