DOWNLOAD INTERNAL COEFFICIENTS (Command ‘v’)
Purpose: Downloads one or more internal coefficients to the module.
Command
““vfaacc[-cc]dddd..dddd”
‘v’ is the command letter.
‘f’ is the format field.
‘aa’ is the array index field.
‘cc[-cc]’ is coefficient index [or contiguous range].
‘dddd’ are the datum field(s) each with a leading space.
‘v’ is the command letter.
‘f’ is the format field.
‘aa’ is the array index field.
‘cc[-cc]’ is coefficient index [or contiguous range].
‘dddd’ are the datum field(s) each with a leading space.
Response
“A”
‘A’ is the acknowledge letter
‘A’ is the acknowledge letter
Description: The 1-character format field (f) is a single decimal digit that defines the format of
each coefficient to be downloaded in the command’s datum ( dddd) fields, with
each datum 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). Sending
a datum in the improper format will result in an “N08" error response. Valid format
types are shown in the following table:
f
converts each internal value from . . .
max. char.
0 1-10-digit signed decimal “ [-xxx]x.[xxxxxx]”
to
single binary float
13
1 8-digit hex integer “ xxxxxxxx”
to
single binary float
9
5 8-digit hex integer “ xxxxxxxx”
to
long binary integer
9
The
2-character
array index field (aa) is a hexadecimal value selecting a
particular internal coefficient array to receive the downloaded data. 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.
A single 1- or 2- character coefficient index field (c or 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.
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.
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:
