DIP Switches:
The four switches on S1 DIP switch configure the operating mode of the EP1502 processor. DIP switches
are read on power-up except where noted. Pressing switch S2 causes the EP1502 to reboot.

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
Subnet Mask: 255.255.0.0
Default Gateway: 192.168.0.1
DNS Server: 192.168.0.1
Primary Host port: IP server, no encryption, port 3001, communication address: 0
Alternate Host Port 1: RS-232, 38,400 baud, no encryption, no flow control.
4. Bulk Erase Configuration Memory:
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 EP1502 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 EP1502 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 EP1502 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 EP1502 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 EP1502 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.
