The LNL-3300 Intelligent System Controller (ISC) by Lenel is designed for advanced access control applications. As the access control engine for the OnGuard® system, the ISC provides power and functionality.

The ISC can communicate to the host computer in a single- or dual- path configuration of Ethernet, dial-up or direct connect RS-485 communication. Multiple combinations of Input Control Modules, Output Control Modules and Card Reader Interface Modules (up to 64 devices) can be configured.

On-board high-speed Ethernet 10/100Base-T upstream port

provides up to 8 times higher throughput than serial-to-Ethernet

converters. DHCP and fixed IP addressing supported.
