by the connected transducer(s).
Command Format
Syntax
$PASHQ,XDR[*cc]
Parameters
None.
Response Format
Syntax
$GPXDR,c1,f2,c3,s4,…,n(c1,f2,c3,s4)*cc
The response uses the same format as the one used at the
input of the transducer ($WIXDR and $YXXDR).
The data set from each transducer is in the form c1, f2, c3,
s4. Data sets from several transducers can be sent through a
single message as long as the total number of characters in
the data string does not exceed 180 characters.
