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:

converts each datum parameter value (‘ dddd’) from..

max. char.

1-10 digit signed decimal “ [-xxx]x.[xxxxxx]” to single

binary float

8-digit hex “ xxxxxxxx”

single

binary float

8-digit hex “ xxxxxxxx”

long

binary 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.
