2.1 GENERAL

The hard disk in the PC is an independent device with its own echogram
definition. Several telegram types may be enabled for on-line storage. When
LOG in the Disk Menu is ON, the data will automatically be given a name
including creation time. The file will be terminated at the current file size given
in MAX. FILE SIZE in the Disk Menu or by turning Disk Menu/Log = OFF. The
postprocessing system will read these files and enable the user to scrutinize the
data with new layer limits.
The SHOW program supplied with the Utility Disk enables the user to convert
the binary telegrams stored in a file into an ASCII readable file for easy
inspection of EY 500 data.
All relevant files are stored in the EY 500 directory.
