READ INTERNAL COEFFICIENTS (Command ‘u’)

Purpose: Returns one (or more contiguous) requested internal coefficient(s) in a specified

internal coefficient array, and in the specified response data format.

Command

“ufaacc[-cc]”

‘u’ is the command letter.

‘f’ is the format field.

‘aa’ is the array index field.

‘cc[-cc]’ is coefficient index [or contiguous range].

Response

“ dddd.. dddd”

‘dddd’ are the datum fields, each with leading space character.

Description: The 1-character format field (f) is a single decimal digit that defines the format of

each returned datum in the response. All datum ( dddd) fields returned will be

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). Requesting an

improper format will result in an “N08" error response. Valid format types for

coefficients are shown in the following table:

converts each internal value from..

max. char.

single binary float to 7-10 digit signed decimal “

[-xxx]x.xxxxxx”

single binary float to 8-digit hex “ xxxxxxxx”

long binary integer to 8-digit hex “ xxxxxxxx”

The 2-character array index field (aa) is a hexadecimal value selecting a

particular internal coefficient array. The first array index (aa=01) refers to

channel one’s transducer, the 16th (aa=10) refers to channel sixteen’s transducer.

Finally, the last array (aa=11) refers to a special global array. Models 9021 and

9022 would have no data for aa=OD-10 since they only have 12 channels.

A single 2- character coefficient index field ( cc) is a hexadecimal value that selects

a particular coefficient within the specified array. Multiple contiguous coefficients

of the same type may be specified by using a coefficient index“range” specified

by adding a hyphen (negative sign) between two such indexes (cc-cc).
