DIP Switches:
The four switches on S1 DIP switch configure the operating mode of the EP4502 processor.
DIP switches are read on power-up except where noted. Pressing reset switch S2 or the processor reset
switch S1 (on the processor board) causes the EP4502 to reboot.

All other switch settings are unassigned and are reserved for future use.
In the factory or OEM default modes, downloaded configuration/database is not saved to flash memory.
Factory Default Communication Parameters:
Network: static IP address: 192.168.0.251
Communication address: 0
Primary Host port: IP server, no encryption, port 3001.
4. The bulk erase function can be used for the following purposes:
Erase all configuration and cardholder database (sanitize board).
Update OEM default parameters after OEM code has been changed.
Recover from database corruption causing EP4502 board to continuously reboot.
If clearing the memory does not correct the initialization problem, contact technical support.
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 EP4502 board.
3. Watch for LEDs 1 & 2 and 3 & 4 to alternately flash at a 0.5 second rate.
4. Within 10 seconds of powering up, change switches 1 or 2 to "OFF". If these switches are not
changed, the EP4502 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.
7. When complete, only LEDs 1 & 4 will flash for 8 seconds.
8. The EP4502 Board will reboot 8 seconds after LEDs 1 & 4 stop flashing (no LEDs are on during this
time).
5. Input Power, Cabinet Tamper and UPS Fault Input Wiring:
The EP4502 requires 12-24 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 12-24 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.
