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) 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.

Factory Default Communication Parameters

Interface 1 (NIC1)

  • Network: static IP address: 192.168.0.251
  • Subnet Mask: 255.255.0.0
  • Default Gateway: 192.168.0.1
  • DNS Server: 192.168.0.1
  • Primary Host port: IP server, Data Security: TLS if Available, port 3001, communication address: 0
  • Alternate Host Port: Disabled


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 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.


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) 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)
  • 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 +/- 2Ω resistor 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.

12V PASS

J7 Reader Power Select

12 VDC is available on reader ports (VIN is greater than or equal to 20 VDC).

VIN power is “passed through” (PASS) to reader ports.


Caution

If the input voltage to the LNL-X2220 is 12 VDC, jumper J7 MUST be in the PASS position.

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.

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.

Running: After initialization is complete, the LEDs have the following meanings:
