Returned Sense Data
A.1 Error/Event Parameter Identification Codes
Table A-1 lists the identification codes that the ACL might report in the Error/Event Log data
returned for acl_errlog_library. For some of these codes, additional integer values are
included to further describe the condition detected. In many cases, this additional information
is intended for Ampex factory personnel as interpretation of integer values requires a detailed
understanding of ACL internal operation.
