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	13
			binary float
1	8-digit hex “ xxxxxxxx”	to	single	9
			binary float
5	8-digit hex “ xxxxxxxx”	to	long binary	9
			integer

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.

A2-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.
