Chapter 2: Architectural Overview

2 – 2

Notes The table below outlines features of the NT500 Security Man-

agement Suite.

In an online application, most access control decisions are

performed by a component called a controller. The controller

is a circuit board with on-board memory, and this on-board

memory must be configured by users who understand access

control functions and features.

The online configuration is accomplished through

operator entering data on or through a computer called a

server. This server is a computer where the access control

system database resides. An operator can enter configura-

tions in the server database through the NT500 System soft-

ware interface and these updates are sent over the computer

network to the appropriate controllers.

When used offline, the same readers, locks, and controllers

can be used with the NT500 System. Updates to the access

parameters for a cardholder or door are made using a PDA or

laptop connected directly to the affected lock. Offline use is

most often the solution chosen for a site that does not need

real time updates. Offline use also has lower up front costs.

The main focus of this guide is the offline use of the NT500

System software. Therefore, NT510 and NT520 system users

are the primary audience for this guide.
