Overview

Access It! Universal.NET has entries available within the AIUniversal database to change the default communications settings for the Mercury-Security hardware. These settings should only be changed if advised by a RS2 Engineer, and when experiencing un-resolvable communications issues. To access the AIUniversal database, SQL Server Management Studio must be used. In most cases it can be access from the access control server (machine with dongle attached) by browsing to Start | Programs | Microsoft SQL Server.
