Figure 2. CR-510 (Front Panel)
(Note: When you first turn on the Card Reader, all of the Front Panel Lights will come on for about
a second.)
A chart of error conditions associated with these lights appears in Appendix C.
START/STOP Button Press this button to begin card reading. Press a second time to stop
the unit once the current card has been read. Pressing START while in the Single-Feed Mode
causes the unit to read one card. In the Continuous Feed Mode, press START to read cards
in the Hopper.
SELF-TEST Button Press this button to start the Self-Test.
There are two kinds of Self-Tests you can run:
• The Diagnostic Self-Test (described at the end of this section).
• A quick Self-Test with the Mechanical Feed Test. Place some cards (marked or unmarked)
in the Hopper and press the Self-Test button. All Front Panel lights will come on for
about one second. When the Self-Test is successfully completed, the lights will go off and the
cards will quickly feed through. If the lights remain on, or the cards don't feed through,
perform the Diagnostic Self-Test.
LOAD/ATTENTION Indicator This light indicates that the Computer expects more cards,
but the Hopper is empty. This condition can also be activated through software. A flashing
lamp indicates that an ATN command was sent by the Computer. See Chapter 4 for additional
information.
READY Indicator This indicator illuminates when the START button has been pressed and
the unit is ready to read cards. When it blinks, or lights up along with other indicators, an
error condition exists.
FEED ERROR Indicator When this indicator is illuminated, a mechanical failure of some
kind has occurred.
Power Indicator When the Card Reader is connected to an outlet and the power switch is set
to ON, this indicator will illuminate.
