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 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:
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”
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 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:
