Intelligent Dual Reader Controller
LNL-2220
The LNL-2220 Intelligent Dual Reader Controller (IDRC) by Lenel 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 LNL-2220’s downstream port to expand its capabilities. The
LNL-2220 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-2220 is scalable for any access
control application, from the most basic to the most sophisticated. In the event of communication
loss, the LNL-2220 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-2220 can
communicate upstream to the host computer through its Ethernet port (with a throughput up to
eight times greater than the fastest serial connections), or at up to 115.2 Kbps using RS-232
communication directly or through an external dial-up modem. The LNL-2220 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, Bioscrypt RS-485 readers and the
bidirectional RS-485 Open Supervised Device Protocol (OSDP) communications. Each LNL-2220
supports up to eight different card formats. The LNL-2220 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.
