2.12 Memory Backup Battery

The SRAM is backed up by a rechargeable battery when input power is removed. This

battery should retain the data for about 2 weeks. If data in the SRAM is determined to

be corrupt after power up, all data, including flash memory, is considered invalid and

are erased. All configuration data must be re-downloaded.

The initial charge of the battery may take up to 24 hours to be fully charged.

Note:

2.13 Status LEDs

Power-up: All LEDs OFF.

Initialization: LEDs 1, 2, 3, 4, 5, 6, and 7 are sequenced during initialization. LEDs 1,

3, and 4 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 application

initialization. When LEDs 1, 2, 3 and 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 repeats, perform the Bulk Erase Configuration Memory

procedure described in

memory does not correct the initialization problem, contact technical support.
