9.8 Result Code
Result codes are informational messages sent from the IS425A and
displayed on your monitor. These messages are the IS425A’s response to
the commands you issue to the IS425A. A result code can be either a
word or a numeric representation.
♦
By default, your IS425A returns a word response after a command is
issued. For example, if your
IS425A successfully executes a
command line, it will send you the response “OK”. However, if
your IS425A is operating under a programming language that either
cannot handle character strings or handles them inefficiently, you
may choose to use the “V0” command to have your IS425A return
numerical responses.
