Read, Write Film Parameters Group 2--
Read, Write Film Parameters
Commands A & B
(A) Read film parameters. These commands are used to read all of the film parameters. The group
command is the letter A followed by the film number, which can be from 1 through 50, followed
by a parameter number. Either a comma or white space needs to separate the arguments. Each
film parameter has a number associated with it.
(B) Write film parameters. These commands are used to set the film parameters of the STC-2000A.
Its format is similar to the read commands above. The command is the letter B followed by the
film number (1 through 50), the film parameter number, the character =, and the data value (as
returned with a matching A query).
Command: A
Mnemonic:
EXCT_rdfp (read film parameters)
Parameters: [1..50] [delimiter] [1 .. 46]
corresponding to film # 1..50 and parameter types DENS .. FRATDR .
Description: Requests a read back from the selected film of the selected parameter value. See the
list of parameters and the corresponding ID code below.
Returns:
[RZCD_AOK][param_value]
if proper film # (1..50) and parameter id were sent. Exact format of [param_value]
depends on the particular parameter for which the data was requested.
[RZCD_ILDV] (H or I) if improper value for parameter arguments.
[RZCD_ILSN] (J or K) if too many arguments, wrong delimiters, etc.
______________________________________________________________________
Command: B
Mnemonic: EXCT_wrfp (write film parameters)
Parameters: [1..50] [delimiter] [1 .. 46] [assign_delim] [desired_value] corresponding to film # 1..50
and parameter types DENS .. FRATDR as in A command above. The assign_delim is zero or
more spaces preceding the '=' sign followed by zero or more spaces. The desired_value is a
numeric data item of proper range and representation (# of decimals points, etc..) used to
update or change the value of the parameter to. This value is expressed in the same manner
as returned to the host when an A type command is issued. Therefore the data return from
an 'A [FILM#] [PARAM#]' query command can be appended to a 'B [FILM#] [PARAM#]
=' command, forming a legal B command which will download the same value to a
parameter as was uploaded with the 'A' command. This makes it easy to save and restore the
STC-2000A instrument's parameters via a host computer.
Description: Command to set or store a new parameter value into one of the film programs.
Returns:
[RZCD_AOK] (A or B) if correctly processed.
