Figure 3 ‐ 2 System Structure for 256 doors
3.3 System for More theN 256 Doors
Each NAV Controller can control up to 31 Flex controllers. And multiple NAV Controllers can be
controlled and communicate with a Navigation software central server. Navigation software is the
enterprise level software to manage middle to large scale access control system. Navigation software
can be installed as central server mode or node server mode. All NAV Controllers can synchronize data
and events to the central server. As a result, a larger scale system can be built with many NAV
Controllers (each can control 31 Flex controllers) under the Navigation software. This large scale system
is illustrated in the below figure:
