Corrective Action Required
Set all DIP Switches to OFF and then set the DIP Switch correctly while
referring to the "Software Information Sheet".
Firmly connect all of the Communication Connectors.
Check for any bent, missing or damaged Pins in the Connector Plugs and
mating Receptacles.
Exchange the CPU Circuit Board with a known good Circuit Board.
Verify that the correct interface between the Host Machine and the Banknote
Acceptor is being used.
NOTE: The Error Codes flash different patterns
when in the normal operation mode
(communicating with the Host Machine) or when
performing the Performance Tests. The LED
shows more detailed flash patterns while running
the Performance Test to identify the specific
error causes.
