APPENDIX A. OPTIONS
Options include a capacitor for the Power-Failure Card-Eject System.
POWER FAILURE CARD EJECT SYSTEM
The externally mounted power-fail capacitor is shown in Figure A- 1.
Figure A- 1. Card Eject Capacitor
The power-failure card-eject system ejects a card during a power failure. Card ejection is
triggered when the power to the reader fails. An external backup capacitor is required for this
option to function. This capacitor can be connected to the reader through a header on the board.
In case of power failure, the capacitor automatically ejects the card. The user must determine the
wire length required for their specific application. The recommended capacitor value is 68000uF
rated at 16 volts.
