! Commands received as valid but that can not be performed:
A valid command in the Echo or Ack/Nak mode that can not be performed will respond with:
:NAC
The conditions that give you a ‘NAC’ response are:
♦ Not in a valid mode for the command. For example, a ’Cal’ command in the
‘normal (run)’ mode (Refer to Command Performance Status Table Below).
♦ The Command is acting on a parameter that is disabled in Configuration. For
example, Peak data recall command when the Peak is configured for ‘off’.
(Refer to Command Performance Status Table I Below).
♦ The command is acting on a parameter that can not be performed due to the
unit conditions such as motion or over range.
