SYNOPSIS
Show input_file [> output_file]
Show -a input_file [> output_file]
Input_file is a EY 500 .dgx file
(Refer to chapter "The Disk Storage" in section "Description of Telegrams and
Remote Control" in the EY 500 Instruction Manual.
DESCRIPTION
The Simrad EY 500 echo sounder outputs binary telegrams over the DISK
interface and the RS232 interface on PC (default COM2). This program
translates binary telegrams into ASCII telegrams providing a useful mechanism
for displaying the content of binary data. Using DOS command input is taken
from the EY 500 input file name at the command line,and output is sent to the
standard output (CRT or a an output file). The telegram formats, binary and
ASCII, are described in the EY 500 Instruction Manual, section "Description of
Telegrams and Remote Control". Five telegrams are only output in binary
format by the EY 500, due to their large size, and no ASCII equivalent is
defined in the EY 500 manual. The full content of these telegrams are printed
in ASCII using the -a option.The compressed ASCII output formats are
described below.

Q1 contains complete echogram data and allows an entire survey to be replayed
and recomputed off line on a general purpose computer: header, time tag, data
type (volume backscattering strength, target strength), detected depth [meter],
upper depth boundary of pelagic echogram [meter],lower depth boundary of
pelagic echogram [meter], number of pelagic echogram data points, upper depth
boundary of bottom echogram [meter], lower depth boundary of bottom
echogram [meter], number of bottom echogram data points.
