ERROR MESSAGES
The MFC-CB always replies to a command except for the use of any of the IEEE STD.
488.2 Common Commands (non query form) via the IEEE-488 interface. If the command is
incorrect or contains invalid data, an error number will be returned in the form “ERR#
n
”
where
n
is an integer number that represents a specific error. This allows for easy error
trapping by the host computer. Table 9 is a list of the possible error numbers and the error
description for each.
