TM
The Fortress’s BestDock communication slot accepts optional communication cards, like the
internal BestLink SNMP/WEB adapter. The insertion of a card into the BestDock communication
slot replaces the normal communication channel from the Fortress’s DB-9 Communication Port.
The DB-9 port becomes the connection point for configuring the card in the BestDock.
