Architecture of Access Easy Controller 2.1

The basic architecture of an AEC2.1 system can be divided into two main building blocks,
namely the Power and the Function. The Power block provides the required power to all the
modules and sustains the system in times of AC power failure. The electrical input sources
vary according to individual electrical power standards in the country.
The Function block can be divided into three different modules namely the Software, the
Processor and the Interface module. These modules work together to define the system's
characteristics and behaviors. Interactions between the modules are carried out through
standard RS232 and RS485 channels. Such architecture structure allows versatilities in
system designing and building.
