Resolution

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 the board to continuously reboot

Bulk Erase Steps (Factory Reset):

Do not remove power during steps 1-8

1. Set S1 DIP switches to: 1 & 2 "ON", 3 & 4 "OFF" (see DIP switch location and diagram below)
2. Apply power to the 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 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 board will reboot 8 seconds after LEDs 1 & 4 stop flashing (no LEDs are on during this time) 

All other switch settings are unassigned and reserved for future use.
