The LNL-500 Intelligent System Controller (ISC) by Lenel serves as the access control engine for an OnGuard system. The ISC provides power, performance, and flexibility for the most demanding applications. Multiple combinations of Input Control Modules, Output Control Modules, and Card Reader Interface Modules can be connected. The ISC can communicate upstream at 38.4 Kbps via RS-232/RS-485 multidropped configuration, modem dial-up communication, or Ethernet TCP/IP networks. The ISC can store up to 12,500 cardholders. The ISC can have two downstream 2-wire RS-485 channels or one 4-wire RS-485 channel. In either configuration, you may connect up to 32 readers or 16 devices. Each device (LNL-1100, LNL-1200, LNL-1300,LNL-1320) uses one device address.

The Lenel OpenCard Reader series includes the most flexible readers in the industry. A single reader supports all applicable ISO standards (14443 and 15693), including the new U.S. Government PIV standard. All Lenel OpenCard Readers contain both 125 kHz proximity and 13.56 MHz contactless smart card support in one unit. Lenel OpenCard Readers provide compatibility with Lenel prox, HID® proximity, GE/CASI ProxLite®, XceedID proximity, AWID proximity and most 13.56 MHz technologies (see chart on back). By offering 125 kHz and 13.56 MHz technology in one reader, Lenel protects customers from obsolescence in the transition from proximity technology to contactless smart card technology. Even if customers want to continue using proximity technology today, the new Lenel OpenCard Readers offer economical migration to the latest in smart card technology while accommodating their budget or timeline.
