Description of telegrams and remote control
P3404E/A
9
S1 contains the mean S
v
per ping inside each active main
layer and the effective thickness of the layer: header, time
tag, number of active layers, layer number, mean S
v
[dB],
effective thickness [meter] etc. Note that S
v
values smaller
than -99.9 dB causes $$$.$ to be printed.
Q1 contains main and bottom echogram values in dB as
ASCII text. This long telegram should only be used for
special studies since the capacity of the serial line is
limited and overflows even at a moderate ping rate. The
binary mode is a lot more efficient (See echogram Q1 in
The Disk Storage chapter).

VL reports that a log pulse has been detected and contains
header, time tag, date, updated log distance [nm].
LL is output every log interval and contains the current layer
settings: header, time tag, date, current log distance [nm],
super layer, number of active layers, layer number, layer
type (S, B or P), upper depth [meter], lower depth [meter],
margin distance [meter], the value 1, S
v
threshold value
[dB] etc.
A1 is output every log interval and contains the integration
results within each layer: header, time tag, date, first
active main layer [m
2
/nm
2
], second active main layer
[m
2
/nm
2
] etc. Note that a special exponential format is
used for representing very small and very large numbers.
