Access Hardware
LNL-X2220
Intelligent Dual
Reader Controller
Overview
The LNL-X2220 Intelligent Dual Reader Controller (IDRC) provides
a single board solution for interfacing one or two doors to an
OnGuard® system. In addition, other I/O and reader interface
modules can be added on the controller’s downstream port to
expand its capabilities. The LNL-X2220 controller revolutionizes
access control system architecture by allowing Ethernet
connection directly from an entry location to the OnGuard
server, while still providing the security, functionality, and
modularity of Lenel’s proven hardware platform. The LNL-X2220
controller is scalable for any access control application, from
the most basic to the most sophisticated. In the event of
communication loss, the LNL-X2220 controller allows nearly
all local functionality to continue unimpaired until the server
connection is restored.
Utilizing its native Ethernet communications and an advanced
32-bit processor, the LNL-X2220 controller can communicate
upstream to the host computer through its Ethernet port. The
controller can store up to 250,000 cardholders in non-volatile
flash memory, and supports selective download for larger
cardholder databases. The downstream RS-485 two-wire port
can be used to connect up to 32 devices (maximum 64 doors).
Two on-board reader ports support Data1/Data0, Clock/Data,
Supervised and Unsupervised F2F, Biometric readers and the
bi-directional RS-485 Open Supervised Device Protocol (OSDP)
communications. Each LNL-X2220 controller supports up to
sixteen different card formats. The LNL-X2220 controller includes
eight inputs that support normally open, normally closed,
supervised, and unsupervised circuits. In addition, four output
relays support fail-safe or fail-secure operation.
