iButton Reader
The iButton reader is used to enable and disable the Octopus system via the iButton
Key. The iButton DB-9 serial interface connector provides a computer interface for initial
system setup, and for retrieval of the system event log. The iButton Reader is mounted
outside of the actual ATM safe, but inside the ATM enclosure in an area that is readily
accessible during service. The iButton Reader is wired to the MCU via a multi-conductor
cable.
The bicolor LED on the face of the iButton reader indicates the status of the system.
When using normal external AC power the LED color is solid. When operating on
backup power the LED color flashes. Table 1 below shows the iButton LED indications
for the various system states.
