Parameters
Parameters are used to specify information
necessary to implement the desired command.
The parameters to be used for each command are
predetermined. The number of digits assigned
to each parameter is also predetermined. Refer
to the PC Control Command Tables {page 4} to
configure the appropriate parameters.
When configuring parameters, be sure not to make
the following mistakes.
Correct parameter example: “IS+1000;”
IS1000; Not enough parameters specified
(No direction given for the IF shift)
IS+100; Not enough digits
(Only three frequency digits given)
IS_+_1000; Unnecessary characters (spaces)
between parameters
IS+10000; Too many digits
(Five frequency digits given)
