READ INTERNAL COEFFICIENTS (Command 'u')
Purpose: Returns one (or more contiguous) requested internal coefficient(s) in a specified
internal coefficient array, and in the specified response data format.
Command
“ufaacc[-cc]”
‘u’ is the command letter.
‘f’ is the format field.
‘aa’ is the array index field.
‘cc[-cc]’ is coefficient index [or contiguous range].
Response
dddd[ dddd]...”
‘ dddd’ are the datum fields, each with a leading space.
Description: The 1-character format field (f) is a single digit that defines the format of each
returned datum in the response. All datum ( dddd) fields returned will be
preceded by a space character. Most coefficients have a floating point datum
type (f=0-1), while others have an integer datum type (f=5). Requesting an
improper format will result in an “N08” error response. Valid format types for
coefficients are shown in the following table:
f Converts each internal value from.. max.char.
0 single binary float to 7-10 digit signed decimal
“ [-xxx]x.xxxxxx”
13
1 single binary float to 8-digit hex “ xxxxxxxx” 9
5 long binary integer to 8-digit hex “ xxxxxxxx” 9
The
2-character array index field (aa) is a hexadecimal value selecting a
particular internal coefficient array. The first array index (aa=01) refers to
channel 1's transducer, the 16th (aa=10) refers to channel 16's transducer.
Finally, the last array (aa=11) refers to a special global array.
The
2-character coefficient index field (cc) is a hexadecimal value that selects a
particular coefficient within the specified array. Multiple contiguous coefficients
may be specified by using a coefficient index “range” specified by adding a
hyphen (negative sign) between two such indexes (cc-cc).
