2.5.1 Bulk erase steps
1. Set S1 DIP switches 1 and 2 to ON, and 3 and 4 to OFF.
2. Apply power to the board. LED 1 is on for about 15 seconds while boots up.
3. Change DIP switches 1 or 2 to OFF Within 10 seconds after LEDs 1 and 2, and LEDs 3 and 4 start flashing
alternately at a rate of 0.5 seconds. If these switches are not changed, the board will power up using
the OEM default communication parameters.
4. LED 2 will flash indicating that the configuration memory is being erased. Full memory erase takes up to
60 seconds.
5. When complete, only LEDs 1 and 4 will flash for about three seconds.
6. The board will complete its initialization within two seconds after LEDs 1 and 4 stop flashing.
Caution: Do not remove power during the bulk erase process.
