Information About LNL-X2220

The LNL-X2220, manufactured by UTC Fire & Security Company, is an industrial computer accessory designed to serve as the Lenel LNL-X2220 Intelligent Dual Reader Controller (IDRC). It functions as a single-board solution tailored for interfacing one or two doors to an OnGuard system.

Key specifications of the LNL-X2220 include primary power compatibility ranging from 12 to 24 VDC with a tolerance of ± 10%, supporting a maximum current draw of 500 mA (excluding reader current). Reader ports allow a maximum current draw of 600 mA, which should be added to the primary power current.

For communication, the LNL-X2220 features Ethernet connectivity with support for 10-BaseT/100Base-TX as the primary host communication channel. Additionally, it includes a USB port (2.0) with the option to use an adapter, specifically the pluggable model USB2-OTGE100, for secondary host communication.

The serial I/O device on the LNL-X2220 is equipped with 2-wire RS-485 connectivity, supporting data rates ranging from 2,400 to 115,200 bps. It operates in an asynchronous, half-duplex mode with 1 start bit, 8 data bits, and 1 stop bit.

Input options consist of eight unsupervised/supervised inputs with standard EOL resistance of 1k/1k ohm, 1% 1/4 watt. Additionally, two unsupervised inputs are dedicated to cabinet tamper and UPS fault monitoring. Outputs on the LNL-X2220 include four relays, with normally open contacts supporting 5 A @ 30 VDC resistive load and normally closed contacts supporting 3 A @ 30 VDC resistive load.

The reader interface of the LNL-X2220 operates with regulated 12 VDC power, supporting a maximum current draw of 300 mA per reader. Data inputs are TTL compatible and support F/2F or 2-wire RS-485 configurations. The RS-485 mode operates at data rates ranging from 9,600 to 115,200 bps.

LED outputs provide TTL levels with high > 3 V and low < 0.5 V, with a maximum source/sink current of 5 mA. Buzzer outputs feature an open collector configuration with a maximum 12 VDC open circuit and 40 mA sink.
