 1. About the BioStar System  Secure I/O: The Secure I/O device provides a convenient way to increase the security of externally mounted devices or expand the capabilities of your system. When doors are controlled by a secure I/O device, intruders cannot open doors even if they succeed in uninstalling external devices. To further increase security, the secure I/O device provides encrypted communications between door components. The Secure I/O device has four input switches and two output relays to allow control of multiple components with a single device.  LIFT I/O: The LIFT I/O supports 0-9 device IDs and 12 output ports (12 input ports are not currently supported). Each output can be connected to an elevator button to control access to floors. The LIFT I/O can be connected via RS485 as a slave to Xpass and Xpass Slim devices. Up to 10 LIFT I/O devices can be connected to an Xpass or Xpass Slim device to control up to 120 floors. 1.1 Logical Configuration BioStar is a distributed intelligence system. Instead of the complex wiring and centralized control required by conventional access control systems, Suprema's access control devices can be connected via TCP/IP or wirelessly to a local area network or connected directly via serial connections. User information, access rules, and other data can be distributed to each device to speed up authorization time and provide continual operation even when the connection to the network is lost. As the following graphic illustrates, the BioStar system does not require separate access controllers. This feature provides a distinct advantage over other access control systems, because BioStation, BioEntry Plus, or BioEntry W devices act simultaneously as both a controller and a reader. As a result, Suprema's distributed intelligence approach requires less hardware and less wiring than conventional, centralized access control systems. 12 Copyright ©2014, Suprema Inc.
