Measurement Computing Micro 488/EX rev.2.1 - Manual (Page 120)

Section 5 Command Descriptions
5.50
ERROR This event occurs when the Micro488/EX detects an error condition.
The error condition may be an un-recognized command from the
serial host, an invalid parameter or a bus error. Refer to Appendix B
for a listing of the error conditions which can be detected by the
Micro488/EX. This event is level sensitive. When the Macro
executes, the error status, as read by any of the STATUS commands,
must be read prior to enabling this event again.
STARTUP This edge sensitive event occurs when the Micro488/EX is powered
on, upon the receipt of an ID character, double ID characters or
RESET
command. If a macro has been asssigned as a STARTUP
macro, it sets LOG ON and executes. This is the only event which
cannot be re-enabled within a Macro. Although STARTUP is a valid
condition within the ARM command, it does not ARM.
Once a condition is enabled it remains enabled until it is DISARMed, the event
specified has occurred or until the Micro488/EX is reset.
The ON DOMACRO and ARM commands are mutually exclusive. The
last command issued takes precedence.
