Reader-controller

Appears in the issue.

Lenel Systems International of Pittsford, New York, has introduced the Lenel Intelligent Dual Reader Controller, which combines a network-enabled intelligent system controller with a two-door reader interface module. By eliminating the separate controller, the LNL-2220 simplifies access control. It allows Ethernet connection directly from an entry location to the server and provides up to eight times the throughput of serial-to-Ethernet conversion used by previous-generation devices. On-board reader ports support communication via multiple protocols. The controller offers flexibility in choice of reader brand, technology, and form fact; it also supports biometric and smart card technologies. Up to 32 devices (64 readers) can be connected to the downstream RS-485 port.
