AR331HS supports RS485 data connection. An example of the RS485 looping method benefit
is that you only need 1 wire to loop all 10 readers instead of having 10 separate wires back to the PC,
Local Area Network or multi-door controller. The more readers you have,
the more saving you will get. The RS485’s 9600 baud rate is more than enough
to support the simple data transmission of each reader .
Only pay for what you need
When the office is still small, multiple individual AR331HS can be looped together
to achieve lower cost solution up to 3000 users. As the business grows,
you just need to add an AR716E multi-door controller
at a later stage to upgrade to 16,000 users and global anti-pass back.
