EP2500 Intelligent Controller
Installation and S pecifications:
1. General:
The EP2500 intelligent controller provides decision making, event reporting, and database storage for
the Mercury hardware platform.
It communicates with the host via on-board 10-BaseT/100Base-TX Ethernet port or port 1. Port 1 may
be set up as RS-232, 2-wire RS-485 or an optional 10-BaseT/100Base-TX using a Lantronix Micro100
interface daughter board. Subcontrollers are connected via ports 2 and 3 using 2-wire RS-485.
It is recommended that the EP2500 be mounted .25" above any conductive surface.
2. Setting Up the EP2500 Hardware:

DIP Switches:
The four switches on S1 DIP switch configure the operating mode of the EP2500 processor . DIP
switches are read on power-up except where noted. Pressing switch S2 causes the EP2500 to reset.

Bulk Erase Configuration Memory:
Use the bulk erase function to erase all configuration and cardholder databases. When power is applied
with S1 switches set to 1 & 2 ON and 3 & 4 OFF, there is a 10-second window that if switch 1 or 2 is
changed to the OFF position, memory is erased. The LEDs flash the following pattern when in the reset
window:LED 1 & 2 and LED 3 & 4 flash alternately at .5 second rate. When erasing memory , LED 2
flashes at a 2 seconds rate. DO NOT CYCLE POWER. Erasing memory takes approximately 60
seconds. LEDs1 and 4 flash for 10 seconds after the memory has been erased, then the EP2500 will reboot.
3. Input Power , Cabinet Tamper and UPS Fault Input Wiring:
The EP2500 requires 12-24Vdc 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 LOCA TION within
the System! Multiple earth ground connections may cause ground
loop problems and is not advised.
Observe POLARITY on 12-24Vdc 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.
4. Communication Wiring:
The EP2500 processor communicates to the host via: on-board Ethernet 10-BaseT/100Base-TX port or
on port 1. Port 1 may be configured as RS-232, 2-wire RS-485 or optional Lantronix Ethernet 10BaseT/100Base-TX Micro100 interface. RS-232 interface is for direct one to one connection to a host
computer port, or a modem.
Ports 2 and 3 utilize 2-wire RS-485 interface. The interface allows multi-drop communication on a
single bus of up to 4,000 feet (1,200 m). Use twisted pair (minimum 24 AWG) with shield for the
communication with 120 ohm impedance. Install termination jumpers only on the units at each end of
the communication line.

5. Memory Backup Battery:
The static RAM and the real time clock device are powered by a lithium battery when input power is
removed. This battery should be replaced annually . If the data in the st atic 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. Battery type: BR2325, BR2330, or CR2330.

6. Status LEDs:
Power-up: All LED's OFF.
Initialization: LED's 1 through 6 are sequenced during initialization. LED's 1, 3, and 5 are turned ON
for approximately 4 seconds 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 3 seconds without a card database. Each 10,000 cards will add about 3 seconds to the applica
tion 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 repeat s, perform one of
the steps below .
1. Power-up and tag database as invalid:
Remove input power to the EP2500, place an insulator under the battery clip, wait 5-10
seconds, remove insulator, reapply input power .
2. Power-up without loading database into RAM:
Remove input power to the EP2500, set DIP to a default mode (in a default mode, the database
is not loaded into RAM), reapply input power.
3. Erase all of the configuration and databases (also erases card database for security reasons):
See procedure in DIP switch note in section 2.
If clearing the memory does not correct the initialization problem, contact technical support.
