The series 2 Dual Reader Interface Module board contains LEDs that can be used to verify correct
installation after power up.
The A LED is turned on at the beginning of initialization. If the application program cannot be run, the A
LED will flash at a rapid rate. The dual reader interface module is waiting for firmware to be downloaded.
