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 fields, each with a leading space.
Response
“A”
‘A’ is the acknowledge letter.
Description: The 1-character format field (f) is a single 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
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).
Transducer Coefficient arrays for internal channels 1-16 are selected with
array indexes aa=01 through aa=10 (hex). A special single Other Coefficient
array is selected with array index aa=11 (hex). All the valid coefficient (cc)
indexes (for each of these arrays) are listed in the appropriate tables included in
the description of the previous Read Internal Coefficients ('u') command.
