Issue
An ACX5740/CX9680 does not provide access events to Cyberstation 1.81.
Environment
Cyberstation 1.81 or earlier version
SQL Server 2005
Cause
The ACX 5740/CX9680 was running version 1.1xxxxx/2.1xxxxx firmware. This version of firmware is incompatible with Cyberstation versions 1.81 and earlier.
Resolution
The site was offered the option of upgrading the version of Cyberstation to 1.9x, or down-reving the ACX 5740/CX9680 to version 1.0xxxxx/2.0xxxxx. Flash down-reving the controller was chosen and did resolve the access event delivery issue.
