LP2500 Intelligent
Controller
Installation and Specifications
1. General
The LP2500 intelligent controller provides decision-making, event reporting, and database storage for the
Mercury hardware platform.
The LP2500 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. Sub controllers are connected via ports 1 and 2
using 2-wire RS-485 multi-drop communication busses. The LP2500 requires 12 to 24 Vdc for power.

DIP Switches:
The four switches on S1 DIP switch are used to configure the operating mode of the LP2500 controller. DIP
switches are read on power-up except where noted. Pressing reset switch S2 causes the LP2500 to reboot.

All other switch settings are unassigned and reserved for future use. X = don’t care.
In the factory or OEM default modes, downloaded configuration/database is not saved to flash memory.
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, TLS if Available, port 3001, communication address: 0
Alternate Host Port: Disabled
4. 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 LP2500 board to continuously reboot
If clearing the memory does not correct the initialization problem, contact technical support.

Mercury Security © 2018 LP2500 DOC 10107-0063 REV 1.02 Page 3
Bulk Erase Steps: Do not remove power during steps 1-8.
1. Set S1 DIP switches to: 1 & 2 "ON", 3 & 4 "OFF".
2. Apply power to the LP2500 board. LED 1 on for about 15 seconds while LP2500 boots up.
3. After the LP2500 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 LP2500 board will power up using the OEM default communication parameters.
5. LED 2 will flash indicating that the configuration memory is being erased.
6. Full memory erase takes up to 60 seconds, usually a lot less.
7. When complete, only LEDs 1 & 4 will flash for about 3 seconds.
8. The LP2500 board will complete its initialization in 2 seconds after LEDs 1 & 4 stop flashing.
5. Input Power, Cabinet Tamper and UPS Fault Input Wiring:
The LP2500 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,
suggest installing a jumper wire.
6. Communication Wiring:
The LP2500 controller communicates to the host via: on-board Ethernet 10-BaseT/100Base-TX port and/or the
USB port (2.0) with an optional Micro USB to Ethernet adapter.
Ports 1 and 2 utilize 2-wire RS-485 interface. The interface allows multi-drop communication on a single bus
of up to 4,000 feet (1,219 m). Use 1-twisted pair, shielded, 120 ohm impedance, 24 AWG. 4,000 ft. (1,219 m)
maximum cable length.
PORT 1
2-WIRE RS-485
PORT 2
2-WIRE RS-485
IMPORTANT NOTE! 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!
7. 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. Remove the insulator from the battery holder after installation. Battery type: BR2330 or CR2330.

8. Status LEDs:
Power-up: All LED's OFF.
Initialization: After power is applied or reset switch pushed, LED 1 is ON for about 15 seconds, then LED’s 2
through 6 are flashed once at the beginning of initialization. LEDs 3 and 4 is turned 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 will add about 2 seconds to the application initialization. When LED's 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 the bulk erase procedure, see section 4.

9. IT Security
When installing the LP2500, 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 LP2500 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
LP2500 is commissioned. It is also highly recommended not to configure the LP2500 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 also be enabled over the host
communication port.
