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].
‘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 leading space character.
‘dddd’ are the datum fields, each with leading space character.
Description: The 1-character format field (f) is a single decimal 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:
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 integer “ xxxxxxxx”
9
5 long binary integer
to 8-digit hex integer “ xxxxxxxx”

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 one’s transducer, the 16th (aa=10) refers to channel sixteen’s
transducer. Finally, the last array (aa=11) refers to a special global array.
A single 2- character coefficient index field ( cc) is a hexadecimal value that
selects a particular coefficient within the specified array. Multiple contiguous
coefficients of the same type may be specified by using a coefficient index“range”
specified by adding a hyphen (negative sign) between two such indexes (cc-cc).

The coefficients of internal DH200 transducers used in the Model 9116 are
selected
with
array indexes aa=01 through 10 (hex). All valid coefficient indexes
(for each of these arrays) are listed in the following table:
