Port 2 & 3

2-wire RS-485: 2,400 to 38,400 bps, async

Inputs:

2 non-supervised, dedicated for cabinet tamper and power fault monitoring

6. Status LEDs

Power-up: All LED's OFF.

Initialization: LED's 1 through 6 are sequenced during initialization. LED's 1, 3, and 5 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 applica
tion initialization. When LED's 1 through 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 one of
the steps below.
1. Power-up and tag database as invalid:

Remove input power to the EP2500, place an insulator under the battery clip, wait 5-10
seconds, remove insulator, reapply input power.

2. Power-up without loading database into RAM:

Remove input power to the EP2500, set DIP to a default mode (in a default mode, the database
is not loaded into RAM), reapply input power.

3. Erase all of the configuration and databases (also erases card database for security reasons):

See procedure in DIP switch note in section 2.

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