Read Internal Coefficients - Pressure Systems 9022 User Manual

Pressure Systems, Inc.
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.
"ufaacc[-cc]"
Command
'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:
f
0 single binary float
1 single binary float
5 long binary integer
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).
converts each internal value from..
to 7-10 digit signed decimal " [-xxx]x.xxxxxx"
to 8-digit hex " xxxxxxxx"
to 8-digit hex " xxxxxxxx"
