Intelligent Controller LNL-X2220 Quick Reference
General
The LNL-X2220 intelligent controller provides decision making, event reporting, and database storage for the Lenel
hardware platform. Two reader interfaces provide control for two physical barriers.
The LNL-X2220 communicates with the host via on-board 10-BaseT/100Base-TX Ethernet port or the Micro USB
port (2.0) with an optional Micro USB to Ethernet adapter.
Each reader port can accommodate a reader that utilizes TTL (D1/D0, Clock/Data), F/2F (standard or supervised) or
2-wire RS-485 device signaling (OSDP reader for example) and also provides tri-state LED control, and buzzer
control (one wire LED mode only). Four Form-C relay outputs may be used for door strike control or alarm signaling.
Eight inputs are provided that may be used for monitoring the door contacts, exit push buttons, and alarm contacts.
Input circuits may be configured as unsupervised or supervised. The LNL-X2220 requires 12 to 24 VDC for power.

Bulk Erase Configuration Memory
The bulk erase function can be used for the following purposes:
• Erase all configuration and cardholder database (sanitize board, less third party applications)
• Update OEM default parameters after OEM code has been changed
• Recover from database corruption causing LNL-X2220 board to continuously reboot
If clearing the memory does not correct the initialization problem, contact LenelS2 OnGuard Technical Support.
Bulk Erase Steps
Important: Do not remove power during steps 1-6.
1. Set S1 DIP switches to: 1 & 2 "ON," 3 & 4 "OFF."
2. Apply power to the LNL-X2220 board. LED 1 on for about 15 seconds while LNL-X2220 boots up.
3. After the LNL-X2220 boots up, watch for LEDs 1 & 2 and 3 & 4 to alternately flash at a 0.5 second rate.
4. Within 10 seconds after the above pattern starts, change switches 1 or 2 to "OFF." If these switches are not
changed, the LNL-X2220 board will power up using the OEM default communication parameters.
5. LED 2 will flash indicating that the configuration memory is being erased. Full memory erase takes up to 60
seconds, usually a lot less.
When complete, only LEDs 1 & 4 will flash for about 3 seconds.
6. The LNL-X2220 board will complete its initialization in 2 seconds after LEDs 1 & 4 stop flashing.

Intelligent Controller LNL-X2220 Quick Reference
Input Power, Cabinet Tamper, and UPS Fault Input Wiring
The LNL-X2220 requires 12 to 24 VDC power. Locate power source as close
to the unit as possible. Connect power with minimum of 18 AWG wire.
Connect the GND signal to earth ground in ONE LOCATION within the
system. Multiple earth ground connections may cause ground loop
problems and is not advised.
Observe POLARITY on 12 to 24 VDC input.
There are two dedicated inputs for cabinet tamper and UPS fault monitoring.
Normal (safe) condition is a closed contact. If these inputs are not used, install
a jumper wire.
Communication Wiring
The LNL-X2220 controller communicates to the host via the on-board Ethernet 10-
BaseT/100Base-TX port and/or the USB port (2.0) with an optional USB to Ethernet
adapter.
The serial I/O device communication port (TB3) is a 2-wire RS-485 interface which can
be used to connect additional I/O panels. The interface allows multi-drop
communication on a single bus of up to 4,000 feet (1,219 m). Use 1-twisted pair with
drain wire and shield, 120 ohm impedance, 24 AWG, 4,000 ft. (1,219 m) maximum for
communication.
Important: Install the termination jumper ONLY on the panel at each
end of the RS-485 bus. Failure to do so will compromise the
proper operation of the communication channel.
Reader Wiring
Each reader port supports a reader with TTL (D1/D0, Clock/Data), F/2F (standard or supervised) or 2-wire RS-485
signaling (OSDP reader for example). Power to the readers is selectable: 12 VDC (VIN must be greater than 20
VDC), or power is passed-through (PASS) from the input voltage of the LNL-X2220 (TB1-VIN), 300 mA maximum
per reader port. Readers that require different voltage or have high current requirements must be powered separately.
Refer to the reader manufacturer’s specifications for cabling requirements. In the 2-wire LED mode, the buzzer
output is used to drive the second LED. Reader port configuration is set via the host software.
To fully utilize each reader port:
• TTL signaling requires a 6-conductor cable (18 AWG)
• F/2F signaling requires a 4-conductor cable
• RS-485 signaling requires two 2-conductor cables. Use one cable for power (18 AWG) and one cable for
communication (24 AWG, with drain wire and shield)
Notes: For OSDP cable lengths greater than 200 ft (61 m) or EMF interference, install 120Ω+/- 2Ωresistor
across RS-485 termination ends.
Data 0 and Data 1 wires for Wiegand may be reused for OSDP. However, standard Wiegand cable may
not meet RS-485 twisted pair recommendations. The reuse of cable works best on shorter cable lengths
at lower data rates.

Input Circuit Wiring
There are 8 inputs that are typically used to monitor door position, request to exit, or alarm contacts. Input circuits can
be configured as unsupervised or supervised. When unsupervised, reporting consists of only the open or closed states.
When configured as supervised, the input circuit will report not only open and closed, but also open circuit, shorted,
grounded,* and foreign voltage.* A supervised input circuit requires two resistors be added to the circuit to facilitate
proper reporting. The standard supervised circuit requires 1k ohm, 1% resistors and should be located as close to the
sensor as possible. Custom end of line (EOL) resistances may be configured via the host software.
* Grounded and foreign voltage states are not a requirement of UL 294 and therefore not verified by UL.

Intelligent Controller LNL-X2220 Quick Reference
The input circuit wiring configurations shown are supported but may not be typical:
Relay Circuit Wiring
Four relays with Form-C contacts (dry) are provided for controlling door lock mechanisms or alarm signaling. Each
relay has a Common pole (C), a Normally Open pole (NO) and a Normally Closed pole (NC). When controlling the
delivery of power to the door strike, the Normally Open and Common poles are typically used. When momentarily
removing power to unlock the door, as with a magnetic lock, the Normally Closed and Common poles are typically
used. Check with local building codes for proper egress door installation.
Door lock mechanisms can generate feedback to the relay circuit that can cause damage and premature failure of the
relay plus affect the operation of the LNL-X2220. For this reason, it is recommended that a diode be used to protect
the relay. Wire should be of sufficient gauge to avoid voltage loss.
Diode Selection
Diode current rating: 1x strike current. Diode breakdown voltage: 4x strike voltage. For 12 VDC or 24 VDC strike,
diode 1N4002 (100V/1A) typical.
Memory and Real Time Clock Backup Battery
The static RAM and the real time clock are backed up by a lithium battery when input power is removed. This
battery should be replaced annually. If data in the static RAM is determined to be corrupt after power up, all data,
including flash memory, is considered invalid and is erased. All configuration data must be re-downloaded.
During installation and while the unit is not powered, change the jumper (J19) position from OFF to ON to enable
the battery backup.
Battery type: BR2330 or CR2330.

IT Security
When installing the LNL-X2220, it is important to ensure that it is done in a secure manner.
Upon installation, the user accounts to the web configuration page should be created with secure passwords, and that
all DIP switches are in the off position for the normal operating mode. The LNL-X2220 is shipped from the factory
with a default login account, which is enabled when DIP 1 is moved from OFF to ON. The default login user name
and password will be available for five minutes once enabled. Therefore, it is important that at least one user account
is defined, and the DIP switches are set to OFF before the LNL-X2220 is commissioned. It is also highly
recommended not to configure the LNL-X2220 with an IP address that is accessible from the public Internet.
To further enhance network security, options are available to disable SNMP, Zeroconf discovery, as well as the web
configuration module itself. Additionally, data encryption can be enabled over the host communication port.
Status LEDs
Power-up: All LEDs OFF.
Initialization: After power is applied or the reset switch is pressed, LED 1 is ON for about 15 seconds, then LEDs 2
through 6, R1, R2, and IN1 through IN8 are flashed once at the beginning of initialization.
LEDs 3 and 4 turn ON for approximately 1 second after the hardware initialization has completed, then the
application code is initialized. The amount of time the application takes to initialize depends on the size of the
database, about 1 second without a card database. Each 10,000 cards adds about 2 seconds to the application
initialization.
When LEDs 1 through 4 flash at the same time, data is being read from or written to flash memory; do not cycle
power when in this state.
If the sequence stops or repeats, perform “Bulk Erase Steps” on page 4.
