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.
Response “A”
‘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 datum parameter value (‘ dddd’) from.. max. char.
0 1-10 digit signed decimal “ [-xxx]x.[xxxxxx]” to single binary float 13
1 8-digit hex “ xxxxxxxx” to single binary float 9
5 8-digit hex “ 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.
